Memmert UN30 Universal Oven, compact heating and drying oven with natural convection, 32 litres, up to 300 °C
The Memmert UN30 universal cabinet is the most compact model in the Memmert universal cabinet range and operates using purely natural convection rather than an active fan. With an internal volume of 32 litres, a temperature range of 20 to 300 °C and a unit weight of around 45 kg, it fits on a laboratory bench, where space is usually more limited than in the equipment area of a permanent laboratory. As there is no active air circulation inside the chamber, the UN30 is particularly suitable for applications where vibration-free and low-dust operation are more important than the shortest possible heating time, such as when gently drying light samples or fine powders.Natural convection for vibration-free, low-dust operationUnlike the UF models in the series, the Memmert UN30 universal oven deliberately does not feature an air turbine or a recirculation motor. Heat rises within the chamber purely by convection, without a fan setting air, dust or light sample components in motion. As a result, the operating temperature range starts from at least 5 °C above room temperature up to 300 °C, whilst the forced-air models in the UF series only start from 10 °C above room temperature; however, thanks to forced air circulation, they heat up more quickly and distribute the temperature more actively. For samples that are sensitive to air movement – such as loose powders, fine fibres or specimens that must not be blown away by draughts – the UN30’s natural convection is the ideal choice. A DIN Class A Pt100 temperature sensor with 4-wire measurement ensures the same setting accuracy as in the larger models, despite the simpler airflow principle: 0.1 °C to 99.9 °C and 0.5 °C from 100 °C.ControlCOCKPIT SingleDISPLAY: compact operation with a full range of functionsDespite its compact design, the UN30 does not compromise on any of the control functions found in the larger models. The ControlCOCKPIT SingleDISPLAY, an adaptive, multifunctional digital PID microprocessor controller with a TFT colour graphic display, regulates temperature in Celsius or Fahrenheit, as well as the position of the exhaust air damper, programme duration, time zone and summer/winter time. As no air turbine is fitted, the only parameter omitted is that for the recirculation fan speed. A digital countdown timer with target time can be set from 1 minute to 99 days; the SetpointWait function only starts the process time once the setpoint temperature has been reached. The data logger can be read out and managed via the Ethernet interface; a time-limited trial version of the AtmoCONTROL software is available for download, whilst a USB stick containing the full version is available as an optional accessory.Compact dimensions of the Memmert UN30 universal chamberThe internal dimensions are 400 x 320 x 250 mm, whilst the external dimensions are 585 x 704 x 434 mm. One electropolished stainless steel wire shelf is included as standard; the cabinet can accommodate up to three shelves in total. The maximum load capacity is 60 kg for the entire unit and 20 kg per insert, which is entirely sufficient for smaller sample batches and individual containers. As with the larger models, the interior consists of easy-to-clean stainless steel, reinforced by deep-drawn ribbing, with protected, integrated 4-sided all-round heating; the housing is made of textured stainless steel with a fully galvanised sheet steel rear panel. The fully insulated stainless steel door locks via a 2-point compression door latch. The UN30 is connected to a 230 V or 115 V supply, in each case at 50/60 Hz, with a power consumption of around 1,600 W.Selection guide: choosing the right size from the UN seriesThe Memmert universal cabinet series with natural convection covers a range of internal volumes from 32 to 749 litres. The UN30 is the smallest model in the range. When choosing the right size, the key factors – apart from internal volume – are the footprint and the number of shelves required; not every larger model takes up more floor space than the next smaller one.ModelInternal volumeUN3032 l, footprint 585 x 434 mm, max. 3 shelvesUN5553 l, footprint 585 x 514 mm, max. 4 shelvesUN7574 l, footprint 585 x 514 mm, max. 6 shelvesUN110108 l, footprint 745 x 584 mm, max. 5 shelvesUN260256 l, footprint 824 x 684 mm, max. 9 shelvesUN450449 l, footprint 1,224 x 784 mm, max. 8 shelvesUN750749 l, footprint 1,224 x 784 mm, max. 14 shelvesThe UN30 is the right choice when space on the laboratory bench is limited and only a few samples are being processed at a time. If the number of samples increases, the Memmert UN55 universal cabinet is the obvious next size up, offering 53 litres instead of 32 and 4 shelves instead of 3, whilst taking up only slightly more floor space. All seven sizes in the series can be found in the LT Laborhandel range of climate chambers and incubators.Distinction: TwinDISPLAY and the forced-air versionWithin the UN30 series, the most important purchasing decision is between SingleDISPLAY and TwinDISPLAY. The UN30 described here operates with a single Pt100 sensor and one display; for unattended processes with higher safety requirements, the Memmert UN30plus universal cabinet offers two redundant Pt100 sensors as well as two TFT displays instead of one. Those who would instead prefer to benefit from the shorter heating-up time offered by active air circulation and do not require vibration-free operation will find the Memmert UF30 universal cabinet to be the equivalent model featuring forced air circulation rather than natural convection, whilst retaining the same internal volume of 32 litres.Safety in accordance with DIN 12880, even in the smallest modelThe UN30 also features adjustable electronic temperature monitoring plus a mechanical temperature limiter of protection class 1 in accordance with DIN 12880, which switches off the heating when the temperature reaches approximately 20 °C above the maximum cabinet temperature. A self-diagnostic system assists with fault-finding, and three freely selectable temperature values can be calibrated. CE and EAC markings, as well as a UL certification mark, are present.Application, installation and disposalThe same installation rules apply to the Memmert UN30 universal cabinet when placed on a laboratory bench as for the larger models in the series: a minimum clearance of 15 cm from the wall, a maximum clearance of 20 cm from the ceiling, and a minimum clearance of 5 cm on each side from a wall or adjacent unit. It may be installed at altitudes of up to 2,000 m above sea level at ambient temperatures of 5 °C to 40 °C and a maximum relative humidity of 80 per cent, non-condensing. Electrically, the UN30 is designed for overvoltage category II and pollution degree 2; it must only be transported in an upright position. The interior, made of easy-to-clean stainless steel, can be cleaned using standard laboratory cleaning products. As an electrical appliance, the UN30 is subject to the Electrical and Electronic Equipment Act at the end of its service life and must not be disposed of with household waste; see Regulatory Information below.Typical applicationsThe compact Memmert UN30 universal oven is suitable wherever space is limited or where vibration-free, low-dust heat treatment is more important than a short heating-up time.Drying small sample quantities and laboratory glassware on the laboratory benchVibration-free drying of dust- or air-sensitive samplesTempering, ageing and baking of small material samplesRoutine tests in quality assurance, schools and trainingA compact addition or secondary unit in laboratories with limited spaceInvestment rationale: keep it compact or opt for greater safety straight awayThe UN30 is supplied with 1 electro-polished stainless steel wire mesh shelf; the cabinet is designed to accommodate up to 3 shelves. For day-to-day operation under supervision, the SingleDISPLAY of the UN30 described here is generally sufficient. If a process runs unattended overnight, the redundant sensor system of the Memmert UN30plus universal chamber reduces the risk of an undetected sensor failure. For visual inspection without opening the door, a fully transparent glass door with 4-layer insulation up to 250 °C or 300 °C is available as an option, as are interior lighting and a stacking kit, which allows two UN30 units to be stacked on top of one another to save space. Anyone wishing to use the data logger permanently, rather than just with the time-limited trial version, should add an AtmoCONTROL software licence. For pharmaceutical or standards-compliant applications, we arrange calibration, IQ/OQ and maintenance services, including those accredited by DAkkS in accordance with DKD-R 5-7.Frequently asked questions before purchaseDoes the UN30 fit on a standard laboratory bench?Yes, with a net weight of around 45 kg and external dimensions of 585 x 704 x 434 mm, the UN30 is designed for use on a laboratory bench, provided that the bench can safely support the load.How many samples can fit into the UN30 at once?One wire rack is included as standard; up to 3 inserts, each with a maximum load of 20 kg, are possible, giving a total load capacity of up to 60 kg.Is natural convection sufficient for uniform drying?For most routine applications, yes. For dust- or air-sensitive samples, the gentle natural convection of the UN30 is an advantage; for shorter heating times with larger batches, the Memmert UF30 universal oven offers active air circulation with the same volume.How does the UN30 differ from the UN30plus?Both operate using natural convection and share the same housing; the UN30plus additionally features two redundant Pt100 sensors and TwinDISPLAY for greater process reliability during unattended operation.What is the accuracy of the temperature control?0.1 °C up to 99.9 °C and 0.5 °C from 100 °C onwards, as the UN30, like all models in the series, measures using a DIN Class A Pt100 sensor with 4-wire technology.Can a glass door be retrofitted?A fully transparent glass door with 4-layer insulation up to 250 °C or 300 °C is one of the standard options for the UN30 and can be specified when ordering.Is the UN30 suitable for continuous overnight operation?The mechanical temperature limiter, which complies with protection class 1 according to DIN 12880, switches off the heating in the event of an overtemperature of approximately 20 °C and is designed for unattended operation.Technical detailsAdjustable temperature range20 to 300 °COperating temperature rangeat least 5 °C above room temperature up to 300 °CTemperature setting accuracyup to 99.9 °C: 0.1 °C, from 100 °C: 0.5 °CTemperature sensorPt100, DIN Class A, 4-wire measurementInternal volume32 lInternal dimensions (W x H x D)400 x 320 x 250 mmExternal dimensions of housing (W x H x D)585 x 704 x 434 mmNet weightapprox. 45 kgConnection 230 V50/60 Hz, approx. 1,600 WConnection 115 V50/60 Hz, approx. 1,600 WMaximum number of trays3Trays included1Max. load on unit60 kgMax. load per shelf20 kgInterior materialStainless steel, 4-sided all-round heatingCasing materialTextured stainless steel, galvanised sheet steel rear panelControl systemControlCOCKPIT SingleDISPLAY, PID microprocessor controller, TFT colour graphic displayTimer1 minute to 99 days, digital countdown timerPermissible ambient temperature5 °C to 40 °CPermissible relative humiditymax. 80% rel., non-condensingMaximum installation height2,000 mCertificationsCE, EAC, UL marksContents of delivery1x Memmert UN30 universal cabinetFactory calibration certificate (calibrated at 160 °C)Fully insulated stainless steel door with 2-point locking (compression door seal)1x stainless steel grating, electropolishedRegulatory informationThe Memmert UN30 universal cabinet is registered with the Stiftung Elektro-Altgeräte Register (Stiftung EAR) under WEEE registration number DE 66812464.Customised requirements & procurement serviceOptions available for the UN30 include fully glazed doors with 4-layer insulation up to 250 °C or 300 °C, interior lighting, reinforced grating and perforated sheets, slide-in or floor-standing drip trays, as well as wall brackets, levelling feet, stacking kits and a mobile or fixed base frame.

Memmert UF160 Universal Oven, heating and drying oven with forced circulation, 161 litres, up to 300 °C
Within the eight-tier UF series with forced convection, the Memmert UF160 universal oven marks the exact point at which a benchtop unit becomes a floor-standing oven: 161 litres’ internal volume, a temperature range of 20 to 300 °C and up to 8 shelves for the daily rotation of different batches. The air turbine, which can be electronically controlled in 10 per cent increments, actively distributes the heat throughout the interior and brings samples up to temperature more quickly and evenly than natural convection alone. From drying freshly cleaned laboratory glassware, through the tempering, ageing and firing of material samples, to curing in quality assurance, the UF160 thus covers a wide range of applications in laboratories and industry.Circulating air for even temperature distribution and short heating-up timesThe air turbine in the Memmert UF160 universal oven can be controlled electronically in 10 per cent increments and actively distributes heat throughout the interior, rather than simply allowing it to rise, as is the case with a natural convection oven. As a result, the UF160 reaches its operating temperature range from as low as 10 °C above room temperature up to 300 °C more quickly than a natural convection unit, which only starts operating from around 5 °C above room temperature but operates without any air movement inside the chamber. A DIN Class A Pt100 temperature sensor with 4-wire measurement ensures a setting accuracy of 0.1 °C up to 99.9 °C and 0.5 °C from 100 °C. Those running many different batches with varying setpoint temperatures benefit from the shorter heating phases achieved through active air circulation.ControlCOCKPIT SingleDISPLAY: Operation, programming and data acquisitionThe UF160 is controlled via the ControlCOCKPIT SingleDISPLAY, an adaptive, multifunctional digital PID microprocessor controller with a high-resolution TFT colour graphic display. Settings include temperature in Celsius or Fahrenheit, the speed of the air circulation motor, the position of the exhaust air flap, the programme duration, as well as the time zone and summer/winter time. A digital countdown timer with target time can be set from 1 minute to 99 days; the SetpointWait function only starts the actual process time once the setpoint temperature has actually been reached, which ensures reproducible results in time-critical drying or ageing processes. The integrated data logger can be read, managed and organised via the Ethernet interface; a time-limited trial version of the AtmoCONTROL software is available for download to get you started.Capacity and connections of the Memmert UF160 universal chamberThe interior of the UF160 accommodates up to 8 shelves; 2 electropolished stainless steel grids are included as standard. The cabinet can be loaded with a total of up to 210 kg; a maximum of 20 kg is permitted per shelf. The internal usable space measures 560 x 720 x 400 mm; the external dimensions of the cabinet are 745 x 1,104 x 584 mm, and the net weight is approximately 96 kg. The interior consists of easy-to-clean stainless steel, reinforced by deep-drawn ribbing, with protected, integrated 4-sided all-round heating; the housing is made of textured stainless steel with a fully galvanised sheet steel rear panel. The UF160 can be connected either to 230 V (approx. 3,200 W) or 115 V (approx. 1,800 W), in both cases at 50/60 Hz; a single-phase connection is still sufficient for this size.Selection guide: choosing the right size from the UF rangeEight sizes ranging from 53 to 1,060 litres internal volume make up the Memmert UF range with forced air circulation, each also available with TwinDISPLAY. When selecting the appropriate size, the key factors – alongside the internal volume – are the footprint and the number of shelves required; not every larger model automatically requires more floor space.ModelInternal volumeUF5553 l, footprint 585 x 514 mm, max. 4 shelvesUF7574 l, footprint 585 x 514 mm, max. 6 shelvesUF110108 l, footprint 745 x 584 mm, max. 5 shelvesUF160161 l, footprint 745 x 584 mm, max. 8 shelvesUF260256 l, footprint 824 x 684 mm, max. 9 shelvesUF450449 l, footprint 1,224 x 784 mm, max. 8 shelvesUF750749 l, footprint 1,224 x 784 mm, max. 14 shelvesUF10601,060 l, footprint 1,224 x 1,035 mm, max. 14 shelvesThe UF160 bridges the gap between a benchtop unit and a floor-standing cabinet: whilst having the same footprint as the smaller Memmert UF110 universal cabinet, it offers significantly more capacity – with 8 shelves instead of 5 – in a housing that is only slightly larger. For those who regularly run even larger batches, the next step up is the Memmert UF260 universal cabinet with a capacity of 256 litres. You can find all sizes in this range in the LT Laborhandel range of climate cabinets and incubators.Differences: TwinDISPLAY and the natural convection variantWithin the UF160 series, the key purchasing decision is between SingleDISPLAY and TwinDISPLAY. The UF160 described here operates with a single Pt100 sensor and one display; for unattended processes with higher safety requirements, the Memmert UF160plus universal cabinet offers two redundant Pt100 sensors with mutual monitoring, as well as two TFT displays instead of one. Those who can do without active air circulation – for example, because samples sensitive to dust or air movement are laid out in the open – will find the Memmert UN160 universal cabinet to be the direct counterpart, featuring natural convection rather than an air turbine, whilst offering the same internal volume of 161 litres. On the other hand, those who can manage with a smaller volume will save a considerable amount of floor space with the more compact Memmert UN110 universal cabinet.Safety in accordance with DIN 12880 for unattended operationIn addition to the adjustable electronic temperature monitoring, the UF160 features a mechanical temperature limiter of protection class 1 in accordance with DIN 12880, which switches off the heater at approximately 20 °C above the maximum cabinet temperature – an important safety feature for overnight or weekend runs. An integrated self-diagnostic system assists with fault-finding, whilst the calibration function allows three freely selectable temperature values to be readjusted. The unit bears CE and EAC markings as well as a UL test mark.Application, Installation and DisposalFor the UF160 to operate, a minimum distance of 15 cm from the wall and a maximum distance of 20 cm from the ceiling must be maintained; a minimum distance of 5 cm from the side of the wall or an adjacent unit is sufficient. It may be installed at altitudes of up to 2,000 m above sea level at an ambient temperature of 5 °C to 40 °C and a relative humidity of no more than 80 per cent, non-condensing. Electrically, the cabinet is designed for overvoltage category II and pollution degree 2; it must only be transported in an upright position. The interior, made of easy-to-clean stainless steel, can be maintained using standard laboratory cleaning agents; the robust structured stainless steel construction ensures a long service life. As an electrical appliance, the UF160 is subject to the Electrical and Electronic Equipment Act at the end of its service life and must not be disposed of with household waste; see Regulatory Information below.Typical applicationsWith forced air circulation, an internal volume of 161 litres and a maximum installation altitude of 2,000 m, the Memmert UF160 universal oven is suitable for a wide range of heat treatment processes in laboratories and industry.Drying of laboratory glassware and sample vessels in routine operationTempering, ageing and firing of material samplesTesting and curing in quality assuranceMaterial testing in industrial manufacturingHeat treatment processes in science and researchAn intermediate option for laboratories that require greater capacity than the UF110 can provideInvestment rationale: SingleDISPLAY or TwinDISPLAYThe UF160 is supplied with 2 electropolished stainless steel wire shelves; the cabinet is designed to accommodate up to 8 shelves. For daytime operation under supervision, the SingleDISPLAY of the UF160 described here is generally sufficient. If, on the other hand, drying or ageing processes run unattended overnight or at the weekend, the redundant sensor system of the Memmert UF160plus universal cabinet reduces the risk of a single sensor failure jeopardising the entire batch. For visual inspection without opening the door, a fully transparent glass door rated up to 250 °C or 300 °C is available as an option, as are interior lighting and reinforced wire mesh shelves or perforated metal sheets rated up to 60 kg for heavier samples. Anyone wishing to use the data logger on a permanent basis rather than just with the time-limited trial version should add an AtmoCONTROL software licence. For pharmaceutical or standards-compliant applications, we arrange calibration, IQ/OQ/PQ and maintenance services, including those accredited by DAkkS.Frequently asked questions before purchaseHow many samples can the UF160 hold at once?Two wire racks are included as standard; up to 8 inserts, each with a maximum load of 20 kg, are possible, giving a total load capacity of up to 210 kg.How does the UF160 differ from the UF160plus?Both share the same housing and air turbine; the UF160plus additionally offers two redundant Pt100 sensors, TwinDISPLAY, HeatBALANCE and AutoSAFETY for greater process reliability during unattended operation.Is a natural convection version available in this size?Yes, the Memmert UN160 universal chamber offers the same internal volume of 161 litres, but operates without an air turbine and is suitable for samples sensitive to dust or air movement.What is the accuracy of the temperature control?0.1 °C up to 99.9 °C and 0.5 °C from 100 °C, measured using a DIN Class A Pt100 sensor with 4-wire technology.What power supply is required?Either 230 V at approximately 3,200 W or 115 V at approximately 1,800 W, in each case at 50/60 Hz; a single-phase connection is sufficient.Is the UF160 suitable for continuous operation overnight?The mechanical temperature limiter, which complies with Protection Class 1 as per DIN 12880, switches the heater off if the temperature exceeds approximately 20 °C and is designed for unattended operation.Can a glass door be retrofitted?A full-view glass door rated up to 250 °C or 300 °C is one of the standard options for the UF160 and can be specified when ordering.Technical detailsAdjustable temperature range20 to 300 °COperating temperature rangeat least 10 °C above room temperature up to 300 °CTemperature setting accuracyup to 99.9 °C: 0.1 °C, from 100 °C: 0.5 °CTemperature sensorPt100, DIN Class A, 4-wire measurementInternal volume161 lInternal dimensions (W x H x D)560 x 720 x 400 mmExternal dimensions of housing (W x H x D)745 x 1,104 x 584 mmNet weightapprox. 96 kgPower supply 230 V50/60 Hz, approx. 3,200 WConnection 115 V50/60 Hz, approx. 1,800 WMaximum number of trays8Slots included2Max. load capacity of unit210 kgMax. load per drawer20 kgInner chamber materialStainless steel, 4-sided all-round heatingCasing materialTextured stainless steel, galvanised sheet steel rear panelControl systemControlCOCKPIT SingleDISPLAY, PID microprocessor controller, TFT colour graphic displayTimer1 minute to 99 days, digital countdown timerPermissible ambient temperature5 °C to 40 °CPermissible relative humiditymax. 80% rel., non-condensingMaximum installation height2,000 mCertificationsCE, EAC, UL marksScope of delivery1x Memmert UF160 universal cabinetFactory calibration certificate (calibrated at 160 °C)Fully insulated stainless steel door with 2-point locking (compression door seal)2x electropolished stainless steel gratingRegulatory informationThe Memmert UF160 universal cabinet is registered with the Stiftung Elektro-Altgeräte Register (Stiftung EAR) under WEEE registration number DE 66812464.Customised requirements & procurement serviceOptions available for the UF160 include fully transparent glass doors rated up to 250 °C or 300 °C, interior lighting, reinforced wire mesh shelves and perforated metal sheets supporting up to 60 kg, slide-in or floor-standing drip trays, as well as wall brackets, levelling feet and a mobile or fixed base frame.

Memmert UN110 Universal Oven, heating and drying oven with natural convection, 108 litres, up to 300 °C
The Memmert UN110 universal cabinet is one of the most frequently ordered heating and drying cabinets in the entire Memmert range at LT Laborhandel. With an internal volume of 108 litres, it marks the transition from the compact benchtop units of the UN series to a noticeably larger footprint and greater loading capacity, whilst continuing to operate using purely natural convection within a temperature range of 20 to 300 °C. For laboratories that regularly dry, temper or cure larger batches or several batches in parallel, whilst requiring a vibration-free environment, the UN110 is the obvious choice between a compact benchtop unit and a large-volume floor-standing cabinet.Natural convection for larger batchesThe Memmert UN110 universal oven also deliberately dispenses with an air turbine and a forced-air fan. Heat rises within the chamber purely by thermal convection, without dust or light sample particles being stirred up by a fan. The operating temperature range therefore starts from at least 5 °C above room temperature up to 300 °C. With an internal volume of 108 litres and several shelves loaded simultaneously, uniform natural heat distribution remains crucial, particularly when sensitive or exposed samples must not be affected by air movement. A Pt100 temperature sensor of DIN Class A in a 4-wire configuration ensures a setting accuracy of 0.1 °C up to 99.9 °C and 0.5 °C from 100 °C onwards.ControlCOCKPIT SingleDISPLAY: Operation and data acquisitionThe UN110 is controlled via the ControlCOCKPIT SingleDISPLAY, an adaptive, multifunctional digital PID microprocessor controller with a high-resolution TFT colour graphic display. The temperature can be set in Celsius or Fahrenheit, as can the position of the exhaust air flap, the programme duration, the time zone and summer/winter time. A digital countdown timer with target time can be set from 1 minute to 99 days; the SetpointWait function only starts the process time once the setpoint temperature has actually been reached, ensuring reproducible results for larger batches. The data logger can be read out and managed via the Ethernet interface; a time-limited trial version of the AtmoCONTROL software is available for download.Capacity and dimensions of the Memmert UN110 universal chamberThe interior measures 560 x 480 x 400 mm, whilst the external dimensions are 745 x 864 x 584 mm – a noticeably larger footprint than the smaller UN30, UN55 and UN75 models. Two electropolished stainless steel wire shelves are included as standard, and the cabinet can accommodate up to five shelves in total. The maximum load capacity is 175 kg for the entire unit and 20 kg per shelf. The interior is made of easy-to-clean stainless steel, reinforced with deep-drawn ribbing, and features protected, integrated 4-sided all-round heating; the housing is made of textured stainless steel with a fully galvanised sheet steel rear panel. The UN110 is connected to 230 V (approx. 2,800 W) or 115 V (approx. 1,800 W), in each case at 50/60 Hz.Selection guide: the move to a larger footprintThe Memmert UN series with natural convection covers internal volumes ranging from 32 to 749 litres. The UN110 is the first model in the series to offer a noticeably larger footprint compared with the three smaller benchtop models.ModelInternal volumeUN3032 l, footprint 585 x 434 mm, max. 3 shelvesUN5553 l, footprint 585 x 514 mm, max. 4 shelvesUN7574 l, footprint 585 x 514 mm, max. 6 shelvesUN110108 l, footprint 745 x 584 mm, max. 5 shelvesUN260256 l, footprint 824 x 684 mm, max. 9 shelvesUN450449 l, footprint 1,224 x 784 mm, max. 8 shelvesUN750749 l, footprint 1,224 x 784 mm, max. 14 shelvesFor those upgrading from the UN75 (74 litres, same footprint as the UN55) and requiring more volume and a higher load capacity per unit, the UN110 is the ideal next step. If even that is no longer sufficient, the Memmert UN260 universal cabinet offers a significantly larger, freestanding model with a capacity of 256 litres. The full range of climate cabinets and incubators can be found under Climate Cabinets & Incubators.Distinction: natural convection versus forced air circulationAnyone requiring more active heat distribution and shorter heating times for a similar volume – for example, with densely packed batches of varying sizes – will find the ideal forced-air equivalent in the Memmert UF160 universal cabinet, which features an electronically controlled fan. Its operating temperature range starts at 10 °C rather than 5 °C above room temperature. For samples sensitive to dust or air movement, the natural convection of the UN110 remains the more suitable choice. A significantly more compact natural convection model for smaller sample quantities is the Memmert UN30 universal cabinet. Like all standard models in the UN series, the UN110 operates with the ControlCOCKPIT SingleDISPLAY, rather than the TwinDISPLAY reserved for the ‘plus’ variants.Safety in accordance with DIN 12880, even with larger batchesThe UN110 features adjustable electronic temperature monitoring and a mechanical temperature limiter of protection class 1 in accordance with DIN 12880, which switches off the heating when the temperature reaches approximately 20 °C above the maximum cabinet temperature – an important safety feature for overnight or weekend runs when several shelves are occupied simultaneously. A self-diagnostic system assists with fault-finding, and 3 freely selectable temperature values can be calibrated. The unit bears CE and EAC markings as well as a UL mark.Installation, operation and disposalFor operation, a minimum clearance of 15 cm from the wall and a maximum clearance of 20 cm from the ceiling must be maintained; a minimum of 5 cm is sufficient on either side relative to the wall or an adjacent unit. With a net weight of around 74 kg, it is recommended that the UN110 be placed on a fixed, load-bearing base rather than simply on a laboratory bench. Installation is permitted at altitudes of up to 2,000 m above sea level at an ambient temperature of 5 °C to 40 °C and a relative humidity of no more than 80 per cent, non-condensing. Electrically, the UN110 is designed for overvoltage category II and pollution degree 2; it must only be transported in an upright position. As an electrical appliance, the UN110 is subject to the Electrical and Electronic Equipment Act at the end of its service life and must not be disposed of with household waste.Typical applicationsWith an internal volume of 108 litres and a load capacity of up to 175 kg, the Memmert UN110 universal cabinet is suitable for laboratories and businesses that regularly dry or heat-treat larger quantities of samples.Drying large quantities of laboratory glassware and sample containersVibration-free drying of dust- or air-sensitive materials in multiple batchesTempering, ageing and firing of material samples in industrial quality assuranceMaterial testing with a higher sample throughput than with the smaller UN modelsScience and research involving varying, sometimes larger, batchesReason for investment: Equipment for higher throughputThe UN110 is supplied with 2 electropolished stainless steel wire mesh shelves as standard; the cabinet is designed to accommodate up to 5 shelves, each with a maximum load of 20 kg.

Memmert IN30 incubator, compact incubator with natural convection, 32 litres, up to 80 °C
The Memmert IN30 incubator is one of the most frequently ordered Memmert instruments at LT Laborhandel. With an internal volume of 32 litres, a temperature range of 20 to 80 °C and purely natural convection, it is designed as a compact incubator for the incubation and cultivation of samples in microbiology, food analysis and pharmacy. An internal glass door allows visual inspection of the cultures without having to open the fully insulated outer door and thereby disturb the internal temperature – a practical difference compared to the pure heating and drying cabinets of the UN series.Natural convection for stable incubation conditionsThe Memmert IN30 incubator operates without an air turbine or a forced-air fan; the heat rises within the chamber purely by thermal convection. This is an advantage for the cultivation of microorganisms and cell cultures: there is no forced air movement that could dry out open Petri dishes or affect culture media. The operating temperature range starts at a minimum of 5 °C above room temperature and extends up to 80 °C. A DIN Class A Pt100 temperature sensor with 4-wire measurement ensures a setting accuracy of 0.1 °C across the entire operating range – a crucial factor for reproducible incubation temperatures, such as 37 °C in microbiology.ControlCOCKPIT SingleDISPLAY and data acquisitionThe IN30 is controlled via the ControlCOCKPIT SingleDISPLAY, an adaptive, multifunctional digital PID microprocessor controller with a high-resolution TFT colour graphic display. The temperature can be set in Celsius or Fahrenheit, as well as the position of the exhaust air flap, programme duration, time zone and summer/winter time. A digital countdown timer with target time can be set from 1 minute to 99 days; the SetpointWait function only starts the incubation time once the setpoint temperature has actually been reached, which is important for defined incubation times. The data logger can be read out and managed via the Ethernet interface; a time-limited trial version of the AtmoCONTROL software is available for download.Capacity and dimensions of the Memmert IN30 incubatorThe internal chamber measures 400 x 320 x 250 mm, whilst the external dimensions are 585 x 704 x 434 mm. An electropolished stainless steel wire rack is included as standard; the incubator can accommodate up to three racks in total. The maximum load capacity is 60 kg for the entire unit and 20 kg per shelf, which is more than sufficient for Petri dishes, test tubes and smaller culture vessels. The interior consists of easy-to-clean stainless steel, reinforced by deep-drawn ribbing, with protected, integrated 4-sided all-round heating; the housing is made of textured stainless steel with a fully galvanised sheet steel rear panel. The IN30 is connected to 230 V (approx. 1,600 W) or 115 V (approx. 800 W), in both cases at 50/60 Hz, with noticeably lower power consumption than the UN series incubators with their higher temperature range.Selection guide: choosing the right incubator sizeLT Laborhandel offers a choice of two sizes with natural convection, as well as the forced-air version with TwinDISPLAY for different temperature distribution requirements.ModelInternal volume and controlIN3032 l, natural convection, SingleDISPLAY, max. 3 shelvesIN5553 l, natural convection, SingleDISPLAY, max. 4 shelvesIF30plus32 l, forced air circulation, TwinDISPLAY, max. 3 shelvesFor those who wish to incubate more culture flasks simultaneously whilst still avoiding forced air circulation, the Memmert IN55 incubator with a 53-litre capacity offers the next level. Those who, on the other hand, require active, more uniform air circulation as well as an integrated sterilisation programme will find these functions in the Memmert IF30plus incubator, which is identical in size. The full range of climate chambers and incubators can be found under Climate Chambers & Incubators.Distinction: Incubator versus heating cabinet, IN versus IFUnlike the universal cabinets in the UN series, the IN30 is specifically designed for incubation temperatures up to 80 °C, not for drying or tempering processes up to 300 °C. The inner glass door, included with the IN30, is not part of the standard specification for the UN models and is important for culture monitoring without temperature loss. Within the incubator range, the key purchasing decision is between natural convection (IN series) and forced air circulation (IF series): The IF30plus features an air turbine, two Pt100 sensors for mutual monitoring, a TwinDISPLAY with two screens and a permanently installed sterilisation programme for the interior – all functions that the IN30, with its SingleDISPLAY, does not offer. Those who switch between different sample types and wish to decontaminate the interior between runs are better served by the IF30plus; those who require quiet, vibration-free incubation without air movement are better off sticking with the IN30.Safety in accordance with DIN 12880The IN30 features adjustable electronic temperature monitoring and a mechanical temperature limiter of protection class 1 in accordance with DIN 12880, which switches off the heating when the temperature reaches approximately 20 °C above the maximum chamber temperature – an important feature for incubation runs lasting several days without constant supervision. A self-diagnostic system assists with fault-finding, and three freely selectable temperature values can be calibrated. The unit bears CE and EAC markings as well as a UL mark.Installation, operation and disposalFor operation, a minimum distance of 15 cm from the wall and a maximum distance of 20 cm from the ceiling must be maintained; a minimum of 5 cm is sufficient on either side in relation to a wall or neighbouring unit. Installation is permitted at altitudes of up to 2,000 m above sea level at an ambient temperature of 5 °C to 40 °C and a relative humidity of no more than 80 per cent, non-condensing. Electrically, the IN30 is designed for overvoltage category II and pollution degree 2; it must only be transported in an upright position. The interior and the inner glass door can be cleaned using standard laboratory cleaning agents and disinfectants. As an electrical appliance, the IN30 is subject to the Electrical and Electronic Equipment Act at the end of its service life and must not be disposed of with household waste.Typical areas of applicationWith an internal volume of 32 litres and incubation temperatures of up to 80 °C, the Memmert IN30 incubator is suitable for compact routine applications in microbiology and food technology.Incubation of culture media and cultures in routine microbiological workBacterial count determination and shelf-life testing in food analysisIncubation of small batches in the pharmaceutical industry and researchVisual inspection of ongoing cultures without temperature loss thanks to the internal glass doorCompact entry-level incubator for schools, training and routine laboratoriesReasons for investment: Equipment for day-to-day incubationThe IN30 comes supplied with 1 electropolished stainless steel wire shelf and the internal glass door; the incubator is designed to accommodate up to 3 shelves. For process documentation, we recommend a permanent AtmoCONTROL software licence rather than the time-limited trial version, supplemented by a USB-to-Ethernet adapter. Those wishing to secure access can configure a lockable door with a security lock; for enhanced safety, an additional Pt100 sensor with overtemperature protection is available. For pharmaceutical or standards-compliant applications, we arrange calibration, IQ/OQ/PQ and maintenance services, including those accredited by DAkkS. Those wishing to combine the IN30 with other devices on a shelf or rack will find a space-saving solution in a wall bracket or stacking kit, without taking up any additional floor space.Frequently asked questions before purchaseWhat is the inner glass door for?It allows visual inspection of the cultures without having to open the fully insulated outer door, which reduces temperature fluctuations inside the unit and minimises disruption to the incubation process.Up to what temperature does the IN30 operate?The adjustable temperature range is from 20 to 80 °C; the operating temperature range starts at a minimum of 5 °C above room temperature.How many culture vessels can fit inside at the same time?One wire shelf is included as standard; up to three shelves, each with a maximum load of 20 kg, are possible, for a total load of up to 60 kg.Is the IN30 different from the UN30 universal cabinet?Yes, the IN30 is designed for incubation temperatures up to 80 °C and has an internal glass door, whilst the UN30 operates as a heating and drying cabinet up to 300 °C without an internal glass door.Is the IN30 a medical device?No, according to Memmert’s own MDR classification table, the IN30 is not a medical device; this applies only to the separate m and mplus variants.Is there a version with active air circulation?Yes, the Memmert IF30plus incubator, which is the same size, features forced air circulation, TwinDISPLAY and an integrated sterilisation programme.Is the IN30 suitable for continuous operation over several days?The mechanical temperature limiter, which complies with Protection Class 1 according to DIN 12880, switches off the heating element if the temperature exceeds the set point by approximately 20 °C and is designed for unattended operation.Can the IN30 also be used for drying tasks instead of incubation?In principle, yes, provided the setpoint temperature is within the range of 20 to 80 °C. For higher drying temperatures up to 300 °C, a heating and drying cabinet from the UN series, such as the Memmert UN30 universal cabinet, is the more suitable choice.Technical detailsAdjustable temperature range20 to 80 °COperating temperature rangeat least 5 °C above room temperature up to 80 °CTemperature setting accuracy0.1 °CTemperature sensorPt100, DIN Class A, 4-wire measurementInternal volume32 lInternal dimensions (W x H x D)400 x 320 x 250 mmExternal dimensions of housing (W x H x D)585 x 704 x 434 mmNet weightapprox. 48 kgPower supply 230 V50/60 Hz, approx. 1,600 WConnection 115 V50/60 Hz, approx. 800 WMaximum number of trays3Slots included1Max. load on unit60 kgMax. load per drawer20 kgInterior materialStainless steel, 4-sided all-round heatingCasing materialTextured stainless steel, galvanised sheet steel rear panelControl systemControlCOCKPIT SingleDISPLAY, PID microprocessor controller, TFT colour graphics displayTimer1 minute to 99 days, digital countdown timerPermissible ambient temperature5 °C to 40 °CPermissible relative humiditymax. 80% rel., non-condensingMaximum installation height2,000 mCertificationsCE, EAC, UL marksContents of delivery1x Memmert IN30 incubatorFactory calibration certificate (calibrated at 37 °C)Fully insulated stainless steel door with 2-point locking mechanism (compression door seal)Inner glass door1x stainless steel wire mesh shelf, electropolishedRegulatory informationThe Memmert IN30 incubator is registered with the Stiftung Elektro-Altgeräte Register (Stiftung EAR) under WEEE registration number DE 66812464.Customised requirements & procurement serviceOptions available for the IN30 include interior lighting and a power socket, a lockable door with a security lock, an additional Pt100 sensor with over-temperature protection, and reinforced wire mesh shelves.

Memmert UF30 Universal Oven, forced-air drying oven, 32 litres, +300 °C
Precision in the smallest of spaces: the Memmert UF30 universal cabinet The Memmert UF30 universal cabinet epitomises German engineering excellence in the field of temperature control technology. In laboratories where space is at a premium but no compromises can be made on temperature accuracy, this model is the first choice. With an internal volume of 32 litres and powerful forced-air circulation technology, the UF30 delivers excellent drying results and unrivalled temperature uniformity. Whether for material testing, ageing tests, drying glassware or baking components – this universal oven masters every thermal task up to +300 °C with flying colours. The principle of forced air circulation (“F” for Forced Air) The key difference between the Memmert UF30 universal oven and static ovens (UN series) is the integrated, high-performance fan. The ‘F’ in the model designation stands for ‘Forced Air Circulation’. Why is this important for your application? Faster drying: Active air movement removes moisture from the sample surface much more efficiently than natural convection. If you need to dry damp granules, painted parts or washed laboratory equipment, the UF30 significantly reduces the process time. Uniform temperature distribution: The fan ensures continuous mixing of the air inside the chamber. This prevents hot spots or cold zones. Even when the cabinet is fully loaded, the temperature remains virtually the same across all shelf levels. This is essential for standard-compliant testing (e.g. in accordance with DIN or ISO). Rapid recovery times: After the door is opened, the UF30 returns to the set temperature in a flash thanks to active air circulation. Unique heating technology: all-round radiant heat One of Memmert’s hallmarks is its all-round heating. Unlike competitors, who often install heating coils only in the base or on the rear wall, the UF30’s heating elements are housed within fins on all four sides of the interior. This greatly increases the heat-emitting surface area. The result is extremely gentle heat transfer without localised overheating points (‘hotspots’). Your valuable samples are not scorched by direct heat radiation, but are heated evenly. This technology also ensures excellent energy efficiency. Stainless steel: Hygienic, robust and durable The Memmert UF30 universal cabinet is made almost entirely of high-quality, stainless steel (grade 1.4301). The interior: It is seamlessly deep-drawn and features rounded corners. This means there are no crevices where dirt or dust can accumulate. Cleaning is completed with just a few wipes – a huge advantage in cleanroom-like environments or in food analysis. The outer casing: The distinctive textured stainless steel sheet is not only a visual highlight in any laboratory, but is also extremely resistant to scratches, fingerprints and mechanical stress. A Memmert cabinet often still looks as good as new even after 20 years. Intuitive operation: ControlCOCKPIT (SingleDISPLAY) The UF30 is controlled via the intuitive ControlCOCKPIT. In the standard version (SingleDISPLAY), this high-resolution TFT touch display offers everything you need for routine operation without overwhelming you with unnecessary complexity. Touch & Turn: You select the function (temperature, fan speed, air damper position, timer) via touch and set the value precisely using the rotary control. Air exchange control: A key feature is the motorised exhaust air flap. You can set on the display how much humid air should escape from the cabinet (0% to 100% opening). This allows for precise control of the drying process. Timer functions: Set a running time or use the ‘SetpointWAIT’ function. With this function, the timer only starts once the target temperature inside the chamber has actually been reached. This ensures that your sample is temperature-controlled for exactly the duration specified. Safety for the laboratory and the sample The Memmert UF30 universal oven is self-monitoring. An electronic temperature monitor (TWW, protection class 3.1) and a mechanical temperature limiter (TB, protection class 1) provide dual protection. Should the electronics fail, the mechanical protection takes over and switches off the heating before any danger arises. Versatility in use Thanks to its compact dimensions, the UF30 fits on any laboratory bench, yet still offers sufficient space for standard applications. Drying: Of powders, granules and electronic components. Ageing: Simulating years of storage through elevated temperatures (plastics, packaging). Curing: Curing of paints or adhesives. Warm-holding: Temperature control of media or bed linen in clinical settings. In summary, the Memmert UF30 is the perfect combination of compact design, speed (thanks to forced air circulation) and legendary build quality. It is a sound investment for any laboratory.

Memmert UN450 Universal Oven, large-capacity heating and drying oven with natural convection, 449 litres, up to 300 °C
The Memmert UN450 universal cabinet offers an internal volume of 449 litres within a comparatively modest overall height of 1,247 mm, meaning it fits even under lower ceilings where a taller model would not. Like all natural convection models in the series, it operates without a fan in the temperature range from 20 to 300 °C and is powered by three-phase current due to the heating power required. For industrial and research facilities wishing to heat-treat large batches without vibration, without needing a particularly tall unit, the UN450 is the ideal solution.Natural convection with a large internal volumeEven with an internal volume of 449 litres, the Memmert UN450 universal chamber does not require an air turbine or a forced-air fan. Heat rises purely by convection, without a fan stirring up dust or light sample particles within the large interior. The operating temperature range extends from at least 5 °C above room temperature up to 300 °C. Natural convection remains in high demand even in this size category, particularly for industrial material samples that must not be affected by air movement. A Pt100 temperature sensor of DIN Class A in a 4-wire configuration provides a setting accuracy of 0.1 °C up to 99.9 °C and 0.5 °C from 100 °C onwards.ControlCOCKPIT SingleDISPLAY and three-phase connectionThe UN450 is controlled via the ControlCOCKPIT SingleDISPLAY, an adaptive, multifunctional digital PID microprocessor controller with a TFT colour graphic display, which can be used to set the temperature, exhaust air damper position, programme duration and time zone. A digital countdown timer ranging from 1 minute to 99 days and the SetpointWait function – which only starts the process time once the setpoint temperature has been reached – ensure reproducible processes, even during long, unattended runs. As a chamber of this size requires correspondingly higher heating capacity, the UN450 is powered by 400 V three-phase current and 3 x 230 V without a neutral conductor at 50/60 Hz and with a power consumption of approximately 5,800 W, rather than the single-phase connection used by the smaller models. The data logger can be read via the Ethernet interface; a time-limited trial version of the AtmoCONTROL software is available for download.Capacity of the Memmert UN450 universal chamberThe internal dimensions are 1,040 x 720 x 600 mm; the external dimensions of the cabinet are 1,224 x 1,247 x 784 mm. There is space for up to 8 shelves; 2 electropolished stainless steel grids are included in the scope of delivery. The UN450 can be loaded with a total of up to 300 kg; each shelf can hold up to 30 kg, which is more than the smaller UN models, which allow 20 kg per shelf. The interior consists of easy-to-clean stainless steel, reinforced by deep-drawn ribbing, with protected, integrated 4-sided all-round heating; the housing is made of textured stainless steel with a fully galvanised sheet steel rear panel. The fully insulated stainless steel doors are secured by a 2-point locking mechanism with a compression door latch.Selection guide: same footprint, different heightsWithin the Memmert UN series with natural convection, the internal volume ranges from 32 to 749 litres. The UN450 and UN750 share the same floor space and differ only in their overall height, which is an important selection criterion where room heights are low.ModelInternal volumeUN3032 l, footprint 585 x 434 mm, max. 3 shelvesUN5553 l, footprint 585 x 514 mm, max. 4 shelvesUN7574 l, footprint 585 x 514 mm, max. 6 shelvesUN110108 l, footprint 745 x 584 mm, max. 5 shelvesUN260256 l, footprint 824 x 684 mm, max. 9 shelvesUN450449 l, footprint 1,224 x 784 mm, max. 8 shelvesUN750749 l, footprint 1,224 x 784 mm, max. 14 shelvesIf you require the maximum capacity within this footprint and have a room height of more than 1.72 m, choose the Memmert UN750 universal cabinet with 749 litres and 14 shelves. If a smaller volume with a smaller footprint is sufficient, the Memmert UN260 universal cabinet with 256 litres is the ideal alternative. The full range of climate chambers and incubators can be found under Climate Chambers & Incubators.Distinction: natural convection versus forced air circulation, UN450 versus UF450In addition to the UN450 with natural convection, LT Laborhandel also stocks the Memmert UN450 universal cabinet, the structurally identical large forced-air version with an electronically controlled fan. The UF450 actively distributes heat throughout the interior and reaches its operating temperature range from as low as 10 °C above room temperature, which ensures shorter heating times for densely packed batches of varying sizes. The UN450 deliberately avoids this and instead starts operating from just 5 °C above room temperature, with absolutely no air movement inside the chamber; this is the right choice for large quantities of material samples that are sensitive to dust or vibration. Both models share the same interior, housing and ControlCOCKPIT SingleDISPLAY, but differ in their ventilation principle and operating temperature range.Safety in accordance with DIN 12880 for long, unattended processesProcess safety is crucial, particularly for large-volume batches that often run overnight or for several days. The UN450 features adjustable electronic temperature monitoring plus a mechanical temperature limiter of protection class 1 in accordance with DIN 12880, which switches off the heating when the temperature reaches approximately 20 °C above the maximum cabinet temperature. A self-diagnostic system assists with fault-finding, and 3 freely selectable temperature values can be calibrated. CE and EAC markings, as well as a UL test mark, are provided.Installation, operation and disposalThe same spacing requirements apply to the operation of the UN450 as for the smaller models: a minimum of 15 cm from the wall, a maximum of 20 cm from the ceiling and a minimum of 5 cm to the side, either from a wall or an adjacent unit. Given a net weight of around 161 kg and the three-phase power connection, the installation site should be fitted with a suitable high-voltage power supply prior to delivery. The unit may be installed at altitudes of up to 2,000 m above sea level, at ambient temperatures of 5 °C to 40 °C and with a maximum relative humidity of 80 per cent, non-condensing. Electrically, the UN450 is designed for overvoltage category II and pollution degree 2; it must only be transported in an upright position. As an electrical appliance, the UN450 is subject to the Electrical and Electronic Equipment Act at the end of its service life and must not be disposed of with household waste.Typical areas of applicationWith an internal volume of 449 litres, up to 8 shelves and a load capacity of up to 300 kg, the Memmert UN450 universal cabinet is designed for high-throughput applications where headroom at the installation site is also limited.Large-volume drying and heat treatment batches in industry and researchRoutine tempering, ageing and baking of material samplesMaterial testing and quality assurance with high sample throughputVibration-free heat treatment of dust-sensitive materials on a large scaleInstallation sites with limited headroom where a UN750 will not fitBusiness case: racks, access control and process monitoringThe UN450 is supplied with 2 electropolished stainless steel grating trays as standard; the cabinet is designed to accommodate up to 8 racks, each with a maximum load of 30 kg. Options for process monitoring include a 4–20 mA current interface, fan speed monitoring, an additional Pt100 sensor and SMS alerts; for controlled access, there is a lockable door with a security lock. Those requiring a gas-tight version with various pipe penetrations can also have this configured. In addition, we supply base frames with levelling, as well as calibration, IQ/OQ/PQ services in accordance with DIN 12880 and maintenance contracts, including those accredited by DAkkS.Frequently asked questions before purchaseWhy does the UN450 require three-phase power?A cabinet of this size requires significantly more heating power – around 5,800 W – than the smaller UN models; therefore, the UN450 is operated with 400 V three-phase power and 3 x 230 V without a neutral conductor, rather than a single-phase connection.How does the UN450 differ from the UF450?Both share the same interior, housing and control system; however, the UF450 also features an electronically controlled fan for active air circulation and has an operating temperature range that starts at 10 °C rather than 5 °C above room temperature.How tall is the UN450 and will it fit under a standard ceiling?The external dimensions are 1,224 x 1,247 x 784 mm; with a height of 1,247 mm, the UN450 also fits into rooms where the taller UN750, at 1,720 mm, would no longer fit.What is the maximum load per shelf?Up to 30 kg per shelf, with a total load of up to 300 kg for the entire unit when fitted with a maximum of 8 shelves.What is the accuracy of the temperature control?Despite the three-phase power supply, the same accuracy applies across the range as for the smaller models: 0.1 °C up to 99.9 °C and 0.5 °C from 100 °C, measured using a DIN Class A Pt100 sensor with 4-wire technology.Is the UN450 suitable for long, unattended processes?The mechanical temperature limiter, which complies with Protection Class 1 according to DIN 12880, switches off the heating element in the event of an overtemperature of approximately 20 °C and is designed for processes running overnight or over several days.Technical detailsAdjustable temperature range20 to 300 °COperating temperature rangeat least 5 °C above room temperature up to 300 °CTemperature setting accuracyup to 99.9 °C: 0.1 °C, from 100 °C: 0.5 °CTemperature sensorPt100, DIN Class A, 4-wire measurementInternal volume449 lInternal dimensions (W x H x D)1040 x 720 x 600 mmExternal dimensions of housing (W x H x D)1224 x 1247 x 784 mmNet weightapprox. 161 kgConnection400 V and 3 x 230 V, neutral, 50/60 Hz, approx. 5,800 WMaximum number of racks8Drawers included2Max. load capacity300 kgMax. load per shelf30 kgInterior materialStainless steel, 4-sided all-round heatingCasing materialTextured stainless steel, galvanised sheet steel rear panelControl systemControlCOCKPIT SingleDISPLAY, PID microprocessor controller, TFT colour graphic displayTimer1 minute to 99 days, digital countdown timerPermissible ambient temperature5 °C to 40 °CPermissible relative humiditymax. 80% rel., non-condensingMaximum installation height2,000 mCertificationsCE, EAC, UL certification marksContents of delivery1x Memmert UN450 universal cabinetFactory calibration certificate (calibrated at 160 °C)Fully insulated stainless steel doors with 2-point locking (compression door seal)2x stainless steel grating, electropolishedRegulatory informationThe Memmert UN450 universal cabinet is registered with the Stiftung Elektro-Altgeräte Register (Stiftung EAR) under WEEE registration number DE 66812464.Customised requirements & procurement serviceOptions available for the UN450 include a lockable door with a security lock, a gas-tight version with various pipe feed-throughs, and reinforced grating and perforated sheets.

Binder FD-S 56 Drying and Heating Oven, Solid.Line with forced convection, 55 l, up to 250 °C, 9090-0018
If you need to dry laboratory glassware reliably after cleaning or store samples at a constant temperature, you don’t need a high-tech cabinet – you need a robust workhorse. The Binder FD-S 56 from the Solid.Line range is built precisely for this purpose: a drying and heating cabinet with forced air circulation and a 55-litre usable volume, deliberately stripped back to the essentials. Rather than offering numerous additional functions, the Solid.Line provides BINDER’s tried-and-tested quality and reliability at a more affordable entry-level price than the Avantgarde.Line (FD series): a conscious choice for anyone looking for a solid convection drying oven without any frills. Solid.Line instead of Avantgarde.Line: reduced but well-thought-out features The FD-S 56 covers a temperature range from 10 °C above ambient temperature up to 250 °C. Whilst this is lower than the maximum offered by the Avantgarde.Line models (up to 300 °C), it is entirely sufficient for most routine applications in drying and heat treatment. Control is via a controller with a timer function; the APT.line preheating chamber technology ensures even temperature distribution inside the chamber despite its simpler design. The exhaust air flap can be adjusted so that the air exchange can be tailored to the specific drying process. Heating times and energy consumption in everyday use At 150 °C, the FD-S 56 achieves a spatial temperature deviation of 2.6 ± K and a temporal deviation of 0.4 ± K. The heating time to 150 °C is approximately 15 minutes; once the door is opened, the set temperature is reached again after about 5 minutes. The air change rate at 100 °C is 4 air changes per hour. Energy consumption at 150 °C is 290 Wh/h: a figure that has a direct impact on running costs when used frequently in day-to-day laboratory work. Typical applications A compact, forced-air drying and heating cabinet such as the FD-S 56 is suitable for day-to-day tasks in laboratories and quality assurance, where reliability in continuous use is more important than the highest temperature accuracy. Drying of cleaned laboratory glassware and sample vessels Warm storage and conditioning of material samples Simple heat treatment processes in quality assurance and training Routine drying in industrial and testing laboratories with limited space With external dimensions of 614 x 577 x 625 mm and a weight of 35 kg, the FD-S 56 fits comfortably on smaller laboratory benches or in ancillary rooms, without compromising on its 55-litre capacity for day-to-day drying tasks.

Do you require any of these accessories or assistance in selecting the right drying and heating cabinet for your application? Through our procurement service, LT Laborhandel will be happy to assist you with procurement and configuration. Selection guide within the range The Solid.Line FD-S series is currently available from BINDER in two sizes. Both share the same temperature range, control concept and features, but differ significantly in terms of usable volume and footprint. ModelUseful volumeExternal dimensions (W x D x H)Well suited for FD-S 56 (9090-0018)55 l614 x 577 x 625 mmsmaller batches, limited floor space FD-S 115 (9090-0024)106 l764 x 616 x 735 mmLarger batches, higher throughput Anyone who regularly dries larger quantities of laboratory glassware or sample material is better served by the FD-S 115. For day-to-day routine operation with smaller quantities, the FD-S 56 described here is generally sufficient. Differences compared to the Avantgarde.Line, Classic.Line and natural convection The Solid.Line is one of three equipment ranges in which BINDER offers drying and heating cabinets. It reliably covers the basic functions, but omits some of the features found in Avantgarde.Line models of the same volume, such as the FD 56: The temperature range tops out at 250 °C instead of 300 °C, and control is via a simpler controller with a timer function rather than an LCD display. In return, the Solid.Line has a lower entry-level price than the Avantgarde.Line, as described in the introductory section. Those who require gentler heat distribution without air movement inside the chamber, rather than forced circulation, will find the ED-S 56 to be the ideal counterpart within the Solid.Line range: the same housing design, but with heat distribution via natural convection rather than via the fan found in the FD-S 56. BINDER also uses the designation Classic.Line for certain smaller models. The current master data does not provide a consistent record of which LT items belong to this third line; therefore, no specific classification is stated here. An overview of the entire Binder range available from LT Laborhandel can be found in the ‘Climate Chambers & Incubators’ category. Application, Operation and Maintenance In day-to-day use, the Solid.Line range really comes into its own in terms of cycle times: the heating-up time to 150 °C for the FD-S 56 is around 15 minutes; once the door is opened, the set temperature is reached again after approximately 5 minutes. The spatial temperature deviation of 2.6 ± K and the temporal deviation of 0.4 ± K at 150 °C are sufficient for most routine applications in drying and heat treatment, even though both values exceed the accuracy of comparable Avantgarde.Line models. If the door is opened frequently – for example, when loading sample vessels in stages – the recovery time of around 5 minutes has a direct impact on overall throughput during daily operation. Practical note: Standard, non-abrasive laboratory cleaners are suitable for cleaning the interior; we advise against the use of abrasive or chlorine-based agents. The built-in Class 2 temperature limiter in accordance with DIN 12880, featuring a visual alarm, provides additional protection against accidental overheating during unattended drying cycles. Calibration is recommended for regular checks of temperature accuracy; LT Laborhandel can arrange suitable calibration certificates via its procurement service. Investment rationale: When Solid.Line is sufficient, and when Avantgarde.Line is worthwhile For routine tasks up to 250 °C, where a simple timer controller is sufficient, the Solid.Line meets requirements reliably and at a lower cost than the Avantgarde.Line. If, on the other hand, a higher temperature range up to 300 °C is required, an LCD display with more precise process control is desired, or the process needs to be documented, a model such as the FD 56 from the Avantgarde.Line is the more suitable choice, even if this entails a higher purchase price. For higher throughput within the Solid.Line range itself, the larger FD-S 115 model is available, rather than switching straight to the Avantgarde.Line. The FD-S 56 comes as standard with a chrome-plated loading rack, including a base support. For higher loading densities, additional loading racks are available as accessories, as are calibration certificates and maintenance contracts of varying scope; both can be obtained via LT Laborhandel’s procurement service. Frequently asked questions about the Binder FD-S 56 What is the usable volume of the FD-S 56?55 litres, with external dimensions of 614 x 577 x 625 mm. What distinguishes the FD-S 56 from the FD-S 115?With a capacity of 106 litres, the FD-S 115 offers roughly twice the usable volume but takes up more floor space; otherwise, both models are technically identical. What distinguishes the Solid.Line from the FD 56 model in the Avantgarde.Line?The FD-S 56 covers a temperature range up to 250 °C, whilst the FD 56 covers a range up to 300 °C. The Avantgarde.Line is also controlled via an LCD display rather than a simple timer controller. Is the FD-S 56 also available with a 120 V connection?Yes, in addition to the 230 V version, the appliance is also available as a 120 V variant. How do I clean the interior?A mild, non-abrasive laboratory cleaner is sufficient. It is best to avoid using abrasive or chlorine-based cleaners (practical advice). Can I have the FD-S 56 calibrated?Yes, LT Laborhandel can arrange the relevant calibration certificates via its procurement service. What is included in the scope of delivery?The FD-S 56 (9090-0018), a chrome-plated insert rack including a base support, and the user manual.
Memmert Incubator IN750m, 749 l, +20 to +80 °C, SingleDISPLAY
The Memmert Incubator IN750m is a Class I medical device under Regulation (EU) 2017/745 with the intended purpose of heating and keeping warm fango, silicate and APS packs in physiotherapy. With 749 litres of internal volume and internal dimensions of 1,040 x 1,200 x 600 mm, it is the largest model in the IN-m series and holds up to 14 shelves, more than any other model in the series.Control, display and data loggerThe ControlCOCKPIT SingleDISPLAY controls the temperature, and its core is an adaptive, multifunctional PID microprocessor controller with a high-resolution TFT colour graphic display. Measurement is made via a Pt100 sensor of DIN class A using 4-wire technology with a setting accuracy of 0.1 °C. The digital countdown timer can be programmed from 1 minute to 99 days, and SetpointWAIT lets the process time begin only once the set temperature has been reached. After a power failure, the program sequence remains stored, the data logger can be read out via Ethernet using the time-limited trial version of AtmoCONTROL, and a USB stick with the software is available as an accessory.Safety and air circulationA mechanical temperature limiter TB of protection class 1 to DIN 12880 switches the heating off at approx. 20 °C above the maximum cabinet temperature, and an adjustable electronic temperature monitor and a self-diagnosis system for fault finding complete the safety technology. Natural ventilation receives pre-heated fresh air via an electronically adjustable exhaust air flap, and an electronically adjustable throttle valve regulates at the exhaust air port. Three temperature values can be freely calibrated.Interior, doors and connectionThe interior is made of easy-care, deep-drawn, ribbed stainless steel and has a protected, integrated 4-sided all-round heating. Two electropolished stainless steel grid shelves are included as standard, and a maximum of 14 shelves is possible at 30 kg per shelf and 300 kg total load. The fully insulated stainless steel doors have 2-point locking with a compression door seal and inner glass doors. The connection is 230 V with approx. 2,000 W or 115 V with approx. 1,800 W, in each case 50/60 Hz. Externally, the IN750m measures 1,224 x 1,720 x 784 mm plus 56 mm door handle, approx. 217 kg net and approx. 288 kg gross in the carton.Distinction: laboratory unit IN750 and IN750mplusWithout a medical intended purpose, the same size is available as the Memmert Incubator IN750. The IN750mplus also offers 749 litres, but shows its values via a ControlCOCKPIT TwinDISPLAY instead of SingleDISPLAY and has a different intended purpose: tempering of irrigation and infusion solutions and contrast media, not heating of fango, silicate and APS packs.Selection guide: which size fitsThe IN750m is the largest model in the series. The smaller IN450m has 449 litres and, with eight shelves, significantly fewer loading positions, at the same total load of 300 kg and the same load of 30 kg per shelf. With 14 shelves and 1,200 mm internal height, the IN750m offers the most shelf levels in the series.Typical applicationsAs a Class I medical device, the IN750m is intended exclusively for the physiotherapeutic applications named in the intended purpose.Heating of fango packs for physiotherapeutic useHeating and keeping warm of silicate packsHeating and keeping warm of APS packsTechnical detailsSetting temperature range+20 to +80 °CWorking temperature rangemin. 5 °C above room temperature to +80 °CTemperature setting accuracy0.1 °CTemperature sensor1x Pt100, DIN class A, 4-wire measurementInternal volume749 lInternal dimensions (W x H x D)1,040 x 1,200 x 600 mmExternal dimensions of housing (W x H x D)1,224 x 1,720 x 784 mm (plus 56 mm door handle)Net weightapprox. 217 kgConnection230 V, 50/60 Hz, approx. 2,000 W; 115 V, 50/60 Hz, approx. 1,800 WShelves in scope of delivery2Shelves, maximum14Max. load, unit300 kgMax. load per shelf30 kgControlControlCOCKPIT SingleDISPLAY, PID microprocessor controller, TFT colour graphic displayMedical device classificationClass I under Regulation (EU) 2017/745Intended purposeHeating/keeping warm of fango, silicate and APS packs in physiotherapyPermissible ambient temperature5 °C to 40 °CPermissible humiditymax. 80 % rel., non-condensingMarkingsCE, VDE, ULOther sizes in the seriesThe IN750m is one of eight sizes in the IN-m series from 32 to 749 litres, all with SingleDISPLAY and the same setting temperature range of +20 to +80 °C.ModelInternal volumeSetting temperatureDisplayIN30m32 l+20 to +80 °CSingleDISPLAYIN55m53 l+20 to +80 °CSingleDISPLAYIN75m74 l+20 to +80 °CSingleDISPLAYIN110m108 l+20 to +80 °CSingleDISPLAYIN160m161 l+20 to +80 °CSingleDISPLAYIN260m256 l+20 to +80 °CSingleDISPLAYIN450m449 l+20 to +80 °CSingleDISPLAYIN750m (this page)749 l+20 to +80 °CSingleDISPLAYScope of deliveryFactory calibration certificate (calibration at +37 °C)Fully insulated stainless steel doors with 2-point locking (compression door seal), inner glass doors2x stainless steel grid shelf, electropolishedRegulatory informationThe device is electrical equipment within the meaning of the German Electrical and Electronic Equipment Act (ElektroG).

Memmert UN750 Universal Oven, large-capacity heating and drying oven with natural convection, 749 litres, up to 300 °C
With an internal volume of 749 litres, the Memmert UN750 universal oven is the largest natural convection model in the entire UN series and, with up to 14 shelves, offers space for significantly more parallel batches than any smaller model in the range. Like all UN models, it does not feature a forced-air fan and operates purely by natural convection within a temperature range of 20 to 300 °C. For businesses with high sample throughput in multi-shift operation, such as in industrial materials testing or quality assurance, the UN750 represents the upper limit of the capacity offered by the natural convection series.Natural convection in the largest size of the seriesEven with an internal volume of 749 litres and 14 possible shelves, the Memmert UN750 universal oven deliberately does without an air turbine and a recirculation fan. Heat rises purely by convection, without a fan stirring up dust or light sample particles – an advantage that is particularly evident when so many levels are occupied simultaneously. The operating temperature range extends from at least 5 °C above room temperature up to 300 °C. A Pt100 temperature sensor of DIN Class A in a 4-wire configuration provides a setting accuracy of 0.1 °C up to 99.9 °C and 0.5 °C from 100 °C onwards, regardless of the number of shelves in use.ControlCOCKPIT SingleDISPLAY and three-phase connection for high utilisationThe UN750 is operated via the ControlCOCKPIT SingleDISPLAY, an adaptive, multifunctional digital PID microprocessor controller with a TFT colour graphic display. Temperature, exhaust air damper position, programme duration, time zone and summer/winter time can all be set. A digital countdown timer ranging from 1 minute to 99 days and the SetpointWait function, which only starts the process time once the setpoint temperature has been reached, ensure reproducible results even during continuous multi-shift operation. Due to the required heating power, the UN750 is operated with 400 V three-phase current and 3 x 230 V without a neutral conductor at 50/60 Hz and approximately 7,000 W. The data logger can be read via the Ethernet interface; a time-limited trial version of the AtmoCONTROL software is available for download.Capacity of the Memmert UN750 universal chamberThe internal dimensions are 1,040 x 1,200 x 600 mm, whilst the external dimensions of the cabinet are 1,224 x 1,720 x 784 mm. It can accommodate up to 14 shelves – more than any other model in the UN series – and two electropolished stainless steel wire shelves are included as standard. The UN750 has a total load capacity of up to 300 kg, with a maximum load of 30 kg per shelf. The interior consists of easy-to-clean stainless steel, reinforced with deep-drawn ribbing, featuring protected, integrated 4-sided all-round heating; the cabinet is made of textured stainless steel with a fully galvanised sheet steel rear panel. The fully insulated stainless steel doors are secured by a 2-point locking mechanism with a compression door latch.Selection guide: the top of the natural convection rangeThe Memmert UN series with natural convection ranges from 32 to 749 litres in internal volume. The UN750 shares the same footprint as the UN450, but is around 47 cm taller and therefore offers almost twice as many shelves.ModelInternal volumeUN3032 l, footprint 585 x 434 mm, 3 shelves max.UN5553 l, footprint 585 x 514 mm, max. 4 shelvesUN7574 l, footprint 585 x 514 mm, max. 6 shelvesUN110108 l, footprint 745 x 584 mm, max. 5 shelvesUN260256 l, footprint 824 x 684 mm, max. 9 shelvesUN450449 l, footprint 1,224 x 784 mm, max. 8 shelvesUN750749 l, footprint 1,224 x 784 mm, max. 14 shelvesIf there is insufficient headroom at the installation site for the UN750’s 1.72 m overall height, the Memmert UN450 universal cabinet—with the same footprint but a significantly lower height—is the practical alternative. For smaller batch sizes, the Memmert UN260 universal cabinet with a capacity of 256 litres is often sufficient. The full range can be found under Climate Cabinets & Incubators.Distinction: natural convection versus forced air circulationWith a capacity of 749 litres and 14 shelves, the question of active air circulation often arises. Forced-air models in the UF series feature an electronically controlled fan, which actively distributes heat throughout the interior, thereby achieving shorter heating times for densely packed batches of varying sizes – though only from 10 °C rather than 5 °C above room temperature. For large quantities of material samples that are sensitive to dust or vibration, the natural convection of the UN750 remains the more technically suitable choice. A forced-air model of a comparable size, albeit smaller, is the Memmert UF450 universal oven with a capacity of 449 litres. Like all standard models in the series, the UN750 uses the ControlCOCKPIT SingleDISPLAY, rather than the TwinDISPLAY, which is reserved for the ‘plus’ variants.Safety in accordance with DIN 12880 at high utilisationWith up to 14 trays occupied simultaneously and processes that often run overnight or for several days, reliable process safety is essential. The UN750 features adjustable electronic temperature monitoring plus a mechanical temperature limiter of protection class 1 in accordance with DIN 12880, which switches off the heating when the temperature reaches approximately 20 °C above the maximum cabinet temperature. A self-diagnostic system assists with fault-finding, and 3 freely selectable temperature values can be calibrated. The unit bears CE and EAC markings as well as a UL mark.Installation, operation and disposalThe same clearance requirements apply during operation as for the smaller models in the series: a minimum of 15 cm clearance from the wall, a maximum of 20 cm clearance from the ceiling, and a minimum of 5 cm clearance to the side from a wall or adjacent unit. With a height of 1.72 m and a net weight of around 217 kg, the room height at the installation site should be checked in advance and a high-voltage connection for three-phase operation should be provided. Installation is permitted at altitudes of up to 2,000 m above sea level, at ambient temperatures between 5 °C and 40 °C and with a maximum relative humidity of 80 per cent, non-condensing. Electrically, the UN750 is designed for overvoltage category II and pollution degree 2; it must only be transported in an upright position. As an electrical appliance, the UN750 is subject to the Electrical and Electronic Equipment Act at the end of its service life and must not be disposed of with household waste.Typical applicationsWith an internal volume of 749 litres and up to 14 shelves, the Memmert UN750 universal cabinet offers the highest throughput of the entire UN series.Heat treatment of very large material batches in industrial multi-shift operationStandard annealing, ageing and curing of numerous material samples in parallelMaterial testing and quality assurance with maximum sample throughputVibration-free heat treatment of dust-sensitive materials on a large scaleCentral heat treatment station for multiple production linesInvestment rationale: optimising capacity utilisationThe UN750 is supplied with 2 electropolished stainless steel grating trays; the cabinet is designed to accommodate up to 14 trays, each with a maximum load of 30 kg. Anyone wishing to utilise the full capacity should factor in the additional grating trays or perforated sheets from the outset. For process monitoring across so many levels, a 4–20 mA current interface, fan speed monitoring, an additional Pt100 sensor and SMS alerts are available; for access control, a lockable door with a security lock is provided. In addition, we supply base frames with levelling, as well as calibration, IQ/OQ/PQ services in accordance with DIN 12880 and maintenance contracts – some of which are DAkkS-accredited – which are particularly recommended for a unit of this size.Frequently asked questions before purchaseHow many samples can the UN750 hold at once?Up to 14 shelves, each with a maximum load of 30 kg, giving a total load capacity of up to 300 kg – more than any other model in the UN series.What ceiling height do I need for the UN750?The external dimensions are 1224 x 1720 x 784 mm; the height of 1.72 m should be checked against the available room height before delivery.Why does the UN750 require three-phase power?With a power consumption of around 7,000 W, the UN750 requires more heating power than can be reasonably supplied by a single-phase supply; therefore, it requires 400 V three-phase power and 3 x 230 V without a neutral conductor.Is the UN750 also available with forced air circulation?A forced-air model with a comparable control system but a smaller capacity is the Memmert UF450 universal cabinet, which has a capacity of 449 litres and an electronically controlled fan.What is the accuracy of the temperature control?Even in the largest model in the series, it remains unchanged: 0.1 °C up to 99.9 °C and 0.5 °C from 100 °C, via a DIN Class A Pt100 sensor using 4-wire technology.Is the UN750 suitable for continuous operation in a multi-shift system?The mechanical temperature limiter, which complies with Protection Class 1 according to DIN 12880, switches off the heating element at an overtemperature of approximately 20 °C and is designed for long, unattended processes.Technical detailsAdjustable temperature range20 to 300 °COperating temperature rangeat least 5 °C above room temperature up to 300 °CTemperature setting accuracyup to 99.9 °C: 0.1 °C, from 100 °C: 0.5 °CTemperature sensorPt100, DIN Class A, 4-wire measurementInternal volume749 lInternal dimensions (W x H x D)1040 x 1200 x 600 mmExternal dimensions of housing (W x H x D)1224 x 1720 x 784 mmNet weightapprox. 217 kgConnection400 V and 3 x 230 V neutral, 50/60 Hz, approx. 7,000 WMaximum number of shelves14Drawers included2Max. load on unit300 kgMax. load per shelf30 kgInterior materialStainless steel, 4-sided all-round heatingCasing materialTextured stainless steel, galvanised sheet steel rear panelControl systemControlCOCKPIT SingleDISPLAY, PID microprocessor controller, TFT colour graphic displayTimer1 minute to 99 days, digital countdown timerPermissible ambient temperature5 °C to 40 °CPermissible relative humiditymax. 80% RH, non-condensingMaximum installation height2,000 mCertificationsCE, EAC, UL marksContents of delivery1x Memmert UN750 universal cabinetFactory calibration certificate (calibrated at 160 °C)Fully insulated stainless steel doors with 2-point locking (compression door seal)2x stainless steel grating, electropolishedRegulatory informationThe Memmert UN750 universal cabinet is registered with the Stiftung Elektro-Altgeräte Register (Stiftung EAR) under WEEE registration number DE 66812464.Customised requirements & procurement serviceOptions available for the UN750 include a lockable door with a security lock, a gas-tight version with various pipe penetrations, and reinforced grating and perforated sheets.

Binder ED-S 56 Drying and Heating Cabinet with Natural Convection, 62 L, up to 250 Degrees Celsius, 9090-0014
The Binder ED-S 56 is a drying and heating cabinet housed in a compact Solid.Line casing, which is identical in construction to the BD-S 056 and FD-S 056 models from the BINDER range. Contrary to what the name ‘ED-S’ might suggest, this is not a conventional incubator, but rather a unit designed for drying and heat treatment tasks: With a temperature range from 7 °C above room temperature up to 250 °C, the ED-S 56 covers a significantly wider range than would be required for incubation tasks alone. The usable volume is 62 l. Natural convection for gentle heating The ED-S 56 operates using natural convection rather than active forced air circulation. Heat is distributed via the heated chamber walls without a fan actively circulating the air inside the chamber. This is a suitable operating principle for drying tasks where gentler, less turbulent air movement is desired, such as when drying laboratory glassware or sample material without active turbulence. The ED-S 56 shares its compact Solid.Line housing with the structurally identical models BD-S 056 and FD-S 056, but differs from them in its significantly extended temperature range up to 250 °C. High temperature range for drying and heat treatment tasks With a temperature range up to 250 °C, the ED-S 56 extends well beyond the range of conventional incubators, which typically stop at around 70 to 100 °C. This makes the unit suitable for applications involving genuine drying, heat treatment or sterilisation processes at higher temperatures, rather than the incubation of living cultures. With external dimensions of 614 x 577 x 625 mm (W x D x H) and a weight of 36 kg, the ED-S 56 remains a compact benchtop unit. The connected load is 1.05 kW.

Do you need help selecting the right unit for your application? We’re happy to help via our procurement service. Selection guide within the range Within the ED-S designation, BINDER currently offers only one size: the ED-S 56 described here, with a 62-litre usable volume. If you require a larger or smaller volume, the suitable alternative is not to be found in a larger ED-S model, but in one of the other Solid.Line product families featuring a comparable, compact housing design.

If natural convection remains a requirement, the ED-S 56 is currently the only Solid.Line option from LT Laborhandel in this market segment. For larger internal volumes with natural convection, the only option in this case is to switch to the Avantgarde.Line ED series, which offers a significantly wider range with six sizes from 20 to 743 l. Distinction from the Avantgarde.Line and the FD-S 56 forced-air model The ED-S 56 belongs to the Solid.Line range, which reliably covers the basic functions but does not include the LCD control panel or the higher temperature range found in the Avantgarde.Line. The Avantgarde.Line counterpart with natural convection is the ED 56, which has a 57-litre usable volume, a temperature range up to 300 °C instead of 250 °C, and an LCD controller with USB data logging. Within the Solid.Line range itself, the FD-S 56 is the forced-air counterpart to the ED-S 56: it features an identical housing design but with an active fan for faster, more uniform heating. The ‘Climate Chambers & Incubators’ category provides an overview of the entire Binder range available from LT Laborhandel. Application, operation and maintenance Without active air circulation, heating up typically takes longer than with the structurally identical FD-S 56 with forced air circulation, for which a heating time of around 15 minutes to 150 °C is documented. We can provide a corresponding figure for the ED-S 56 on request. For processes where steady, low-airflow heating is more important than short cycle times, such as with dust-sensitive samples or sample material stored in the open, this is of secondary importance anyway. The connected load of 1.05 kW is on a par with comparable compact drying and heating cabinets with natural convection in this size range. Practical note: Standard, non-abrasive laboratory cleaners are suitable for cleaning the interior; we advise against using abrasive or chlorine-based products. Calibration is recommended for regular checks of temperature accuracy; LT Laborhandel can arrange suitable calibration certificates via its procurement service. We will provide the class of the adjustable temperature limiter on request. Investment rationale: When Solid.Line is sufficient, and when Avantgarde.Line or forced-air systems are worthwhile If a temperature range up to 250 °C with natural convection is sufficient for drying, heat treatment or sterilisation processes, the ED-S 56 meets this requirement without the need for an LCD control panel or USB data logging. If a higher temperature range up to 300 °C or documented process recording is required, the ED 56 from the Avantgarde.Line is the more suitable choice. If, on the other hand, rapid, uniform heating is the main priority and air movement inside the chamber is not critical, the FD-S 56 with forced air circulation is a better fit. For additional accessories, spare parts, custom calibration or special configurations relating to the ED-S 56, LT Laborhandel’s procurement service is available; it is also worth making an enquiry to confirm the compatibility of insert grids with the identically constructed Solid.Line housing. Anyone unsure whether the ED-S 56 or one of the higher-capacity Avantgarde.Line models is the more cost-effective choice can also seek this assessment via the procurement service, rather than deciding based solely on the data sheet specifications. Frequently asked questions about the Binder ED-S 56 What is the usable volume of the ED-S 56?62 l, with external dimensions of 614 x 577 x 625 mm. Is the ED-S 56 also available in a larger size?No, BINDER currently only offers the ED-S model in this one size. For greater capacity with natural convection, you will need to switch to the Avantgarde.Line ED series. What distinguishes the ED-S 56 from the ED 56 in the Avantgarde.Line range?The ED-S 56 covers a temperature range up to 250 °C, whilst the ED 56 covers a range up to 300 °C and also features an LCD controller with USB data logging. What distinguishes the ED-S 56 from the FD-S 56?Both share the Solid.Line housing, but the FD-S 56 operates with forced air circulation, whilst the ED-S 56 uses natural convection without an active fan. Is the ED-S 56 suitable for sterilisation tasks?The temperature range up to 250 °C is significantly higher than that of conventional incubators, which typically top out at around 70 to 100 °C, and is therefore also suitable for sterilisation processes at higher temperatures. How do I clean the interior?Wipe the interior with a standard, non-abrasive laboratory cleaner. Abrasive cleaners and chlorine-based cleaners are not suitable (practical note). What is included in the scope of delivery?The ED-S 56 (9090-0014) and the user manual. Is the ED-S 56 more suitable for a laboratory or for industrial use?The compact Solid.Line housing and the temperature range up to 250 °C make the ED-S 56 suitable for laboratories and quality assurance, as well as for simple industrial drying and heat treatment tasks where space is limited.
Memmert HPP410eco Constant-Climate Chamber, 384 litres, Peltier technology without a compressor
Contract laboratories and manufacturers running several test programmes simultaneously under ICH conditions need one thing above all else: reliable capacity without compromising on control accuracy. The Memmert HPP410eco constant-climate chamber offers an internal volume of 384 litres and space for up to 14 shelves; temperature and humidity are controlled via a Peltier heating and cooling system that requires no compressor and no conventional refrigerant, with the same control range as the smaller models in the HPPeco range: 0 to 70 °C without humidity control, 5 to 70 °C with active humidity control between 10 and 90 % rh.Peltier cooling even under heavy loadsLike the other HPPeco models, the HPP410eco heats and cools via a Peltier element integrated into the rear panel; there is no conventional refrigeration circuit with a refrigerant whatsoever. Two DIN Class A Pt100 sensors in a 4-wire configuration monitor each other and automatically take over the function of the other sensor in the event of a fault; with 14 possible racks and a total load of up to 200 kg, this is a crucial feature for long, unattended test runs. The setting accuracy is 0.1 °C; when exposed to light, the operating range narrows to 15 to 40 °C, with a maximum load of 20 kg per shelf.Humidity control and ControlCOCKPIT TwinDISPLAYRelative humidity is controlled between 10 and 90 % rh with an accuracy of 0.5 % rh; humidification is provided by a hot steam generator, whilst dehumidification is achieved via a cold trap using Peltier technology. The water supply is provided via an external canister with a connecting hose and a self-priming pump; a fixed water connection is not required. The chamber is operated via the ControlCOCKPIT TwinDISPLAY, which features two TFT colour graphic displays; an Ethernet interface and AtmoCONTROL software are available for documenting multiple parallel test programmes. The SetpointWait function ensures that the test time only begins once the temperature and humidity have actually reached the setpoint.Selection guide: Choosing the right size within the HPPeco rangeWith a capacity of 384 litres and 14 shelves, the HPP410eco is one of the larger models among the four chambers compared here:Memmert HPP110eco constant-climate chamber108 litres, 560 x 480 x 400 mm, approx. 64 kg, up to 5 shelvesMemmert Constant-Climate Chamber HPP260eco256 litres, 640 x 800 x 500 mm, approx. 94 kg, up to 9 shelvesMemmert Constant-Climate Chamber HPP410eco384 litres, 640 x 1200 x 500 mm, approx. 134 kg, up to 14 shelvesMemmert Constant-Climate Chamber HPP750eco749 litres, 1040 x 1200 x 600 mm, approx. 197 kg, up to 14 shelvesThose who regularly require an even larger sample capacity whilst maintaining a similar number of shelves will find the Memmert HPP750eco Constant Climate Chamber (749 litres) to be the next size up, offering, amongst other things, a higher load capacity per shelf. For smaller, less frequent test runs, the HPP260eco or HPP110eco are often the more economical choice; technically, the only differences between all four models are in volume, dimensions, weight and power consumption. You can find an overview of the entire Memmert range of climate chambers and incubators at LT Laborhandel in the Climate Chambers & Incubators category.Differences: HPPeco or ICH110?The Memmert ICH110 climate chamber covers a wider temperature range from –10 to +60 °C and uses a compressor-based, CFC-free R290 system with automatic defrosting; however, at 108 litres, it falls into a significantly smaller volume class than the HPP410eco. For test programmes that remain within the 0 to 70 °C range and process larger batch sizes in parallel, the Peltier technology of the HPP410eco, with a connected load of around 420 W, remains the more energy-efficient option compared to the ICH110’s approximately 1,350 W.Installation, water connection and drainageA minimum distance of 15 cm from the wall, a maximum distance of 20 cm from the ceiling and a minimum side clearance of 5 cm must be maintained; the unit may be installed at altitudes of up to 2,000 m above sea level at an ambient temperature of 16 to 40 °C and a maximum relative humidity of 70 per cent, non-condensing. A fixed water connection in the installation room is not required; the supplied water canister with connecting hose provides the water supply for the humidity control. For disposal as waste electrical and electronic equipment (WEEE), Memmert is registered with the Stiftung Elektro-Altgeräte Register (Stiftung EAR) under WEEE registration number DE 66812464.Investment rationale: Which equipment for which testing purposeWhere several test programmes are being documented in parallel, a USB-to-Ethernet adapter is recommended, together with AtmoCONTROL or myChamber software licences – which can be FDA-compliant for 21 CFR Part 11 environments if required. For long, unattended runs, a potential-free contact for connection to a central control system and a MobileALERT SMS alert system can be added. If several user groups with different access rights are using the device, a lockable door and a USB user ID stick for the TwinDISPLAY are available as options. For permanent installation in the test chamber, a built-in frame with or without ventilation is also available.Typical applicationsWith an internal volume of 384 litres and up to 14 shelves, the Memmert HPP410eco constant-climate chamber is designed for contract laboratories and manufacturers running multiple ICH test programmes simultaneously.Parallel long-term and intermediate storage studies of multiple active substances in accordance with ICH Q1AStability testing for cosmetic and food batches on an industrial development scaleMaterial testing with higher sample throughput in industryEnvironmental testing from freezing point upwards for several parallel test seriesFrequently asked questions about the Memmert HPP410eco constant-climate chamberWhat temperature and humidity range does the HPP410eco cover?Depending on the operating mode, 0 to 70 °C without humidity or 5 to 70 °C with active humidity control between 10 and 90 % rh; with light exposure, the operating range is restricted to 15 to 40 °C.Does the chamber require a fixed water supply?No. An external water container with a connecting hose supplies the humidity control system via a self-priming pump; a fixed water connection in the installation room is not required.How many samples can fit into the HPP410eco?Two shelves are included as standard; a total of up to 14 shelves, each with a maximum load of 20 kg, can be fitted, with the total load not exceeding 200 kg.When does it make sense to switch to the HPP750eco?If you regularly require a larger sample volume with a higher load capacity per tray, the HPP750eco, with a capacity of 749 litres and up to 30 kg per tray, offers greater capacity whilst utilising the same control technology.What distinguishes the HPP410eco from the Memmert ICH110 climate chamber?The HPP410eco cools between 0 and 70 °C using a Peltier element without a compressor or refrigerant, whilst the ICH110 operates with a compressor-based refrigeration cycle (R290) and also covers a range down to -10 °C, albeit with an internal volume of only 108 litres.What software is available for documentation and validation?The chamber can be managed and data read out via Ethernet using the AtmoCONTROL software; for environments where 21 CFR Part 11 compliance is mandatory, Memmert also offers an FDA-compliant licence option.How is calibration carried out?The factory calibration certificate covers the standard values of 25 °C at 60 % rh and 40 °C at 75 % rh; in addition, three freely selectable temperature and humidity values each can be calibrated by the user. For DAkkS-accredited calibrations and IQ/OQ/PQ, LT Laborhandel arranges suitable services.Technical detailsAdjustable temperature range (without light, without humidity)0 to 70 °CAdjustable temperature range (with humidity)5 to 70 °COperating temperature range with lighting15 to 40 °CTemperature setting accuracy0.1 °CTemperature sensor2x Pt100, DIN Class A, 4-wire measurementAdjustable humidity range10 to 90 % rhHumidity setting accuracy0.5% RHInternal volume384 lInternal dimensions (W x H x D)640 x 1200 x 500 mmExternal dimensions of the housing (W x H x D)824 x 1720 x 655 mmNet weightapprox. 134 kgPower supply 230 V50/60 Hz, approx. 420 WConnection 115 V50/60 Hz, approx. 420 WMaximum number of trays14Trays included2Max. load on unit200 kgMax. load per shelf20 kgHousing materialTextured stainless steel housing, fully galvanised sheet steel rear panelControlControlCOCKPIT TwinDISPLAY, PID microprocessor controller, 2 TFT colour graphic displaysTimer1 minute to 99 days, digital countdown timerPermissible ambient temperature16 to 40 °CPermissible relative humiditymax. 70% relative, non-condensingMaximum installation altitude2,000 mCertificationsCE, EAC, UL marksScope of delivery1x Memmert HPP410eco constant-climate chamberStandard factory calibration certificate (25 °C / 60 % rh, 40 °C / 75 % rh)Fully insulated stainless steel door with 2-point locking (compression door seal)Inner glass doorMoisture-tight silicone feed-through (internal diameter 18 mm) with silicone plug2x stainless steel grating, electropolishedWater canister including connection hoseRegulatory informationThe Memmert HPP410eco constant-climate chamber is registered with the Stiftung Elektro-Altgeräte Register (Stiftung EAR) under WEEE registration number DE 66812464.Customised requirements & procurement serviceOptions available for the HPP410eco include a built-in frame with or without ventilation, a potential-free contact for building management systems, and a lockable door.

Memmert UF450 Universal Oven, large-capacity heating and drying oven with forced circulation, 449 litres, up to 300 °C, on castors
With an internal volume of 449 litres, the Memmert UF450 universal cabinet is the largest floor-standing model in the UF range and is designed for batches that no longer fit into smaller heating cabinets. Like the more compact Memmert UF160 universal oven, it features an air turbine with electronic control in 10 per cent increments for forced air circulation and covers a temperature range from 20 to 300 °C. Fitted with castors and lockable, the cabinet – which weighs around 161 kg – can be moved around the laboratory or production hall despite its size, without having to be lifted every time.Large-scale forced air circulation: uniform heat distribution even when fully loadedWith an internal volume of 449 litres and up to 8 shelves, active air circulation is particularly noticeable: without an air turbine, the heat in such a large interior would be distributed much more unevenly and rise more slowly. The UF450’s electronically controlled air turbine ensures that the operating temperature range – which, as with all UF models, is at least 10 °C above room temperature up to 300 °C – is reliably achieved even with large, densely packed batches. A DIN Class A Pt100 temperature sensor with 4-wire measurement provides a setting accuracy of 0.1 °C up to 99.9 °C and 0.5 °C from 100 °C onwards, regardless of the unit size.ControlCOCKPIT SingleDISPLAY and three-phase power connection for industrial useThe UF450 is controlled via the ControlCOCKPIT SingleDISPLAY, an adaptive, multifunctional digital PID microprocessor controller with a TFT colour graphic display, which can be used to set the temperature, recirculation fan speed, exhaust air damper position, programme duration and time zone. A digital countdown timer ranging from 1 minute to 99 days and the SetpointWait function, which only starts the process time once the setpoint temperature has been reached, ensure reproducible processes even during long, unattended runs. As an oven of this size requires correspondingly more heating power, the UF450 is operated with 400 V three-phase current and 3 x 230 V without a neutral conductor at 50/60 Hz and a power consumption of approximately 5,800 W, rather than the single-phase connection used by the smaller models. The data logger can be read via the Ethernet interface; a time-limited trial version of the AtmoCONTROL software is available for download.Capacity of the Memmert UF450 universal chamber for large batchesThe internal dimensions are 1,040 x 720 x 600 mm, whilst the external dimensions of the cabinet are 1,224 x 1,247 x 784 mm. There is space for up to 8 shelves; 2 electropolished stainless steel wire mesh shelves are included. The UF450 can be loaded with a total of up to 300 kg; each shelf can carry up to 30 kg, which is significantly more than the UF160 and considerably more than the compact UN30. The interior consists of easy-to-clean stainless steel, reinforced by deep-drawn ribbing, with protected, integrated 4-sided all-round heating; the housing is made of textured stainless steel with a fully galvanised sheet steel rear panel. The fully insulated stainless steel doors are secured by a 2-point locking mechanism with a compression door latch.Selection guide: choosing the right size from the UF rangeEight sizes ranging from 53 to 1,060 litres of internal volume make up the Memmert UF range with forced air circulation, each also available with TwinDISPLAY. When choosing the right size, the key factors – in addition to the internal volume – are the footprint and the number of shelves required.ModelInternal volumeUF5553 l, footprint 585 x 514 mm, 4 shelves max.UF7574 l, footprint 585 x 514 mm, max. 6 shelvesUF110108 l, footprint 745 x 584 mm, max. 5 shelvesUF160161 l, footprint 745 x 584 mm, max. 8 shelvesUF260256 l, footprint 824 x 684 mm, max. 9 shelvesUF450449 l, footprint 1,224 x 784 mm, max. 8 shelvesUF750749 l, footprint 1,224 x 784 mm, max. 14 shelvesUF10601,060 l, footprint 1,224 x 1,035 mm, max. 14 shelvesThe UF450 sits between the more compact Memmert UF260 universal cabinet (256 litres) and the very large models starting at 749 litres. Those requiring even more capacity will find it in the Memmert UF750 universal cabinet, which is also fitted with castors. All sizes in this range can be found in the LT Laborhandel range of climate cabinets and incubators.Differentiation: TwinDISPLAY and the natural convection variantWithin the UF450 series, the most important decision is between SingleDISPLAY and TwinDISPLAY. The UF450 described here operates with a single Pt100 sensor and one display, for unattended processes with higher safety requirements, the structurally identical Memmert UF450plus universal cabinet offers two redundant Pt100 sensors, the HeatBALANCE function for fine-tuning the heat output distribution, and the additional AutoSAFETY monitoring, each with two TFT displays instead of one. For those who can do without active air circulation entirely – for example, because dust-sensitive samples are laid out in the open – the Memmert UN450 universal cabinet is the ideal alternative, featuring natural convection instead of an air turbine, whilst maintaining the same internal volume of 449 litres.Safety in accordance with DIN 12880 for long, unattended processesProcess reliability is crucial, particularly for large-volume batches that often run overnight or for several days. The UF450 features adjustable electronic temperature monitoring plus a mechanical temperature limiter of protection class 1 in accordance with DIN 12880, which switches off the heating when the temperature reaches approximately 20 °C above the maximum cabinet temperature. A self-diagnostic system assists with fault-finding, and three freely selectable temperature values can be calibrated. The unit bears CE and EAC markings as well as a UL mark.Application, installation and disposalDespite its size, the same spacing requirements apply to the Memmert UF450 universal cabinet as to the smaller models: a minimum of 15 cm clearance from the wall, a maximum of 20 cm clearance from the ceiling and a minimum of 5 cm clearance on either side from a wall or adjacent unit, even though the cabinet can be easily manoeuvred into the correct position thanks to its castors. It may be installed at altitudes of up to 2,000 m above sea level at ambient temperatures of 5 °C to 40 °C and a maximum relative humidity of 80 per cent, non-condensing. Electrically, the UF450 is designed for overvoltage category II and pollution degree 2; despite the castors, it must only be transported in an upright position. The interior, made of easy-to-clean stainless steel, can be cleaned using standard laboratory cleaning agents, even with frequent batch changes. As an electrical appliance, the UF450 is subject to the Electrical and Electronic Equipment Act at the end of its service life and must not be disposed of with household waste; see Regulatory Information below.Typical areas of applicationWith an internal volume of 449 litres, up to 8 shelves and a load capacity of up to 300 kg, the Memmert UF450 universal cabinet is designed for applications with higher throughput.Large-volume drying and heat treatment batches in industry and researchRoutine tempering, ageing and baking of material samplesMaterial testing and quality assurance with high sample throughputCuring processes in which several shelves are occupied simultaneouslyMobile use at different locations thanks to a wheeled baseInvestment rationale: when TwinDISPLAY is worthwhileThe UF450 is supplied with 2 electropolished stainless steel grids; the cabinet is designed to accommodate up to 8 racks. TwinDISPLAY is particularly worthwhile where processes run unattended overnight or at weekends and where a sensor failure would otherwise jeopardise the entire, often large-volume batch: in such cases, the Memmert UF450plus universal cabinet is the safer choice. For daytime operation under supervision, the SingleDISPLAY model described here is sufficient. For visual inspection without opening the door, a fully transparent glass door rated up to 300 °C is available as an option, as is a lockable door with a security lock and interior lighting. For process monitoring, a 4–20 mA current interface, fan speed monitoring and door-open detection are also available. For pharmaceutical or standards-compliant applications, we provide calibration, IQ/OQ/PQ services in accordance with DIN 12880 and maintenance contracts.Frequently asked questions before purchaseHow many samples can the UF450 hold at any one time?Two wire shelves are included as standard; up to 8 shelves, each with a maximum load of 30 kg, are possible, giving a total load capacity of up to 300 kg.Can the cabinet be moved around the laboratory?Yes, the UF450 is mounted on castors that can be locked in place and, despite its net weight of around 161 kg, can be moved within the permitted installation conditions.What type of power connection is required?The UF450 requires 400 V three-phase current at 3 x 230 V without a neutral conductor at 50/60 Hz and has a power consumption of approximately 5,800 W; a single-phase 230 V connection is not sufficient for this size.How does the UF450 differ from the UF450plus?Both share the same housing and air turbine; the UF450plus additionally offers two redundant Pt100 sensors, TwinDISPLAY, HeatBALANCE and AutoSAFETY for greater process reliability during unattended operation.Is a natural convection version available in this size?Yes, the Memmert UN450 universal chamber offers the same internal volume of 449 litres, but operates without an air turbine and is suitable for samples sensitive to dust or air movement.What is the accuracy of the temperature control?0.1 °C to 99.9 °C and 0.5 °C from 100 °C, measured using a DIN Class A Pt100 sensor with 4-wire technology.Is the UF450 suitable for continuous operation overnight?The mechanical temperature limiter, which complies with Protection Class 1 according to DIN 12880, switches off the heating in the event of an overtemperature of approximately 20 °C and is designed for unattended operation.How do I clean the interior between two batches?The interior is made of easy-to-clean stainless steel and can be cleaned using standard laboratory cleaning agents without exposing the 4-sided all-round heating system.Technical detailsAdjustable temperature range20 to 300 °COperating temperature rangeat least 10 °C above room temperature up to 300 °CTemperature setting accuracyup to 99.9 °C: 0.1 °C, from 100 °C: 0.5 °CTemperature sensorPt100, DIN Class A, 4-wire measurementInternal volume449 lInternal dimensions (W x H x D)1,040 x 720 x 600 mmExternal dimensions of housing (W x H x D)1,224 x 1,247 x 784 mmNet weightapprox. 161 kgConnection400 V and 3 x 230 V neutral, 50/60 Hz, approx. 5,800 WMaximum number of shelves8Drawers included2Max. unit load300 kgMax. load per shelf30 kgInterior materialStainless steel, 4-sided all-round heatingCasing materialTextured stainless steel, galvanised sheet steel rear panelControlsControlCOCKPIT SingleDISPLAY, PID microprocessor controller, TFT colour graphic displayInstallationMovable and lockable on castorsTimer1 minute to 99 days, digital countdown timerPermissible ambient temperature5 °C to 40 °CPermissible relative humiditymax. 80% rel., non-condensingMaximum installation height2,000 mCertificationsCE, EAC, UL marksContents of delivery1x Memmert UF450 universal cabinetFactory calibration certificate (calibrated at 160 °C)Fully insulated stainless steel doors with 2-point locking (compression door seal)2x stainless steel grating, electropolishedRegulatory informationThe Memmert UF450 universal cabinet is registered with the Stiftung Elektro-Altgeräte Register (Stiftung EAR) under WEEE registration number DE 66812464.Customised requirements & procurement serviceOptions available for the UF450 include fully transparent glass doors rated up to 300 °C, a lockable door with a security lock, interior lighting, reinforced wire mesh shelves and perforated metal sheets supporting up to 60 kg, as well as a gas-tight version with various pipe feed-throughs.

Memmert HPP260eco Constant-Temperature Chamber, 256 litres, Peltier technology without a compressor
As soon as a single stability study develops into an ongoing test programme involving several formulations, a small chamber is often no longer sufficient. With an internal volume of 256 litres and up to 9 shelves, the Memmert HPP260eco constant-climate chamber offers significantly more capacity than the smallest model in the range, without compromising on temperature and humidity control: 0 to 70 °C without humidity, 5 to 70 °C with active humidity control between 10 and 90 % rh, regulated via a Peltier heating and cooling system without a compressor and without conventional refrigerant.Peltier cooling for parallel test runsLike all four sizes in the HPPeco range, the HPP260eco heats and cools via a Peltier element integrated into the rear wall, operating on the heat pump principle. There is no need for a separate refrigeration circuit with conventional refrigerant, which reduces maintenance requirements compared with compressor-cooled climate chambers. Two DIN Class A Pt100 sensors in a 4-wire configuration monitor each other and automatically take over the function of the other sensor in the event of a fault – a crucial safety feature for a chamber that typically runs continuously for several weeks at a time. The temperature setting accuracy is 0.1 °C; when exposed to light, the operating range is restricted to 15 to 40 °C.Humidity control and ControlCOCKPIT TwinDISPLAYRelative humidity can be set between 10 and 90 % rh with an accuracy of 0.5 % rh; a hot steam generator humidifies the chamber, whilst a Peltier-based cold trap dehumidifies it. The water supply is provided by an external canister with a connecting hose and a self-priming pump; a fixed water connection is not required. The HPP260eco is controlled via the ControlCOCKPIT TwinDISPLAY with two TFT colour graphic displays; test runs are managed and documented via the Ethernet interface and the AtmoCONTROL software. The SetpointWait function only starts the test time once both the temperature and humidity have reached the setpoint, which helps ensure the comparability of results when multiple formulations are running in parallel.Selection guide: Choosing the right model size in the HPPeco rangeWith a capacity of 256 litres, the HPP260eco sits between the compact entry-level model and the two larger chambers in the series:Memmert HPP110eco constant-climate chamber108 litres, 560 x 480 x 400 mm, approx. 64 kg, up to 5 shelvesMemmert Constant-Climate Chamber HPP260eco256 litres, 640 x 800 x 500 mm, approx. 94 kg, up to 9 shelvesMemmert Constant-Climate Chamber HPP410eco384 litres, 640 x 1200 x 500 mm, approx. 134 kg, up to 14 shelvesMemmert Constant-Climate Chamber HPP750eco749 litres, 1040 x 1200 x 600 mm, approx. 197 kg, up to 14 shelvesIf 9 shelves are consistently insufficient for the planned test programmes, it is worth considering the Memmert HPP410eco constant-climate chamber with a capacity of 384 litres and 14 shelves. On the other hand, if you only test individual batches occasionally, the more compact Memmert HPP110eco Constant Climate Chamber is often the more cost-effective solution; technically, the only differences between all four models are in volume, dimensions, weight and power consumption. You can find an overview of the entire Memmert range of climate chambers and incubators at LT Laborhandel in the Climate Chambers & Incubators category.Choosing between the HPP110eco and the ICH110?For test programmes that also require temperatures below 0 °C or compressor-based cooling with automatic defrosting, the Memmert ICH110 climate chamber is the suitable alternative, although, at 108 litres, it falls into a smaller volume class than the HPP260eco. The ICH110 covers a range from –10 to +60 °C and uses the CFC-free R290 refrigerant; however, its connected load of around 1,350 W is significantly higher than the HPP260eco’s approximately 420 W. As long as the test range is between 0 and 70 °C, the Peltier technology of the HPP260eco remains the more energy-efficient and low-maintenance choice.Installation, water connection and drainageA minimum distance of 15 cm from the wall, a maximum distance of 20 cm from the ceiling and a minimum distance of 5 cm from the side must be maintained; the unit may be installed at altitudes of up to 2,000 m above sea level at ambient temperatures of 16 to 40 °C and a maximum relative humidity of 70 per cent, non-condensing. The supplied water canister with connecting hose supplies the humidity control system; a fixed water connection in the installation room is not required. For disposal as waste electrical and electronic equipment, Memmert is registered with the Stiftung Elektro-Altgeräte Register (Stiftung EAR) under WEEE registration number DE 66812464.Investment rationale: Which equipment for which test purposeFor validated, documented test runs, a USB-to-Ethernet adapter is ideal in combination with AtmoCONTROL or myChamber software licences; an FDA-compliant version for 21 CFR Part 11 environments is available on request. Where several test series are running in parallel with different user groups, a lockable door and a USB user ID stick can be added to the TwinDISPLAY. For unattended runs, a potential-free contact for connection to a central control system and a MobileALERT SMS alert system are available as options. For installation, a castor frame with a supply air filter, levelling feet and a levelling or mobile base frame are also available, along with accessories for the water supply.Typical areas of applicationWith an internal volume of 256 litres and up to 9 shelves, the Memmert HPP260eco constant-climate chamber is suitable for laboratories that test multiple formulations or batches in parallel under controlled ICH conditions.Parallel stability studies of several active ingredient batches in accordance with ICH Q1AStability testing for cosmetic and food formulations during ongoing developmentMaterial testing in industrial quality assurance involving a large volume of samplesEnvironmental testing from freezing point upwards in research and developmentFrequently asked questions about the Memmert HPP260eco constant-climate chamberWhat temperature and humidity range does the HPP260eco cover?Depending on the operating mode, 0 to 70 °C without humidity or 5 to 70 °C with active humidity control between 10 and 90 % rh; when light exposure is applied, the operating range is restricted to 15 to 40 °C.Does the chamber require a fixed water connection?No. Humidity is supplied via the water canister supplied with the unit, which includes a connection hose and a self-priming pump.How many samples can fit into the HPP260eco?Two trays are included as standard; a total of up to nine trays, each with a maximum load of 20 kg, can be used, provided the total load does not exceed 200 kg.When does it make sense to switch to the HPP410eco?If you regularly require more than 9 trays at the same time or a total load exceeding 200 kg, the HPP410eco, with a capacity of 384 litres and up to 14 trays, offers greater capacity whilst retaining the same control technology.What distinguishes the HPP260eco from the Memmert ICH110 climate chamber?The HPP260eco cools between 0 and 70 °C using a Peltier element without a compressor or refrigerant, whilst the ICH110 operates with a compressor-based refrigeration cycle (R290) and also covers a range down to -10 °C, albeit with an internal volume of only 108 litres.What software is available for documentation and validation?The HPP260eco can be managed and read via Ethernet using the AtmoCONTROL software; for environments subject to 21 CFR Part 11, Memmert also offers an FDA-compliant licence option.How is calibration carried out?A calibration certificate is supplied as standard (reference values: 25 °C at 60 % rh and 40 °C at 75 % rh); in addition, three freely selectable values each for temperature and humidity can be calibrated by the user.

Binder FD 56 Drying and Heating Oven with forced air circulation, 60 l, up to 300 °C, 9010-0303
The Binder FD 56 drying oven from the Avantgarde.Line FD series is a drying and heating oven with forced convection, designed for applications requiring particularly rapid drying and sterilisation. With a usable volume of 60 litres and a temperature range from 10 °C above ambient temperature up to 300 °C, this compact benchtop unit is equally suitable for daily laboratory routines and for specific sterilisation processes. Rapid heating thanks to a powerful fan A powerful fan, combined with APT.line technology, ensures uniform temperature distribution throughout the entire interior. At 150 °C, the FD 56 achieves a spatial temperature deviation of 1.7 ± K and a temporal deviation of 0.3 ± K. The heating time to 150 °C is just 15 minutes. With an air change rate of 80 times per hour at 100 °C, rapid, uniform drying is achieved even with a dense load. Operation and features in everyday laboratory use The FD 56 is controlled via a controller with an LCD display; the exhaust air flap is controlled electromechanically and can thus be adapted to the respective drying or sterilisation process. With a sound pressure level of 43 dB(A) and energy consumption of 290 Wh/h at 150 °C, the unit is also suitable for continuous operation in everyday laboratory use. Typical applications Drying of laboratory glassware and sample material in routine laboratory work Sterilisation processes in quality assurance and research Rapid heat treatment of small to medium-sized batches Complementary unit to larger drying and heating cabinets For laboratories that regularly need to dry small to medium quantities of glassware or sample material, the FD 56 combines short heating times with a compact footprint, without compromising on temperature accuracy.

Do you require bespoke configurations, spare parts or advice on selecting the right drying oven for your application? LT Laborhandel will be happy to assist you via our procurement service. Selection guide within the range BINDER’s Avantgarde.Line FD range with recirculation comprises five sizes. All share the same temperature range, LCD controller and electromechanically controlled exhaust air flap, but differ significantly in terms of usable volume and footprint. ModelUseful volumeExternal dimensions (W x D x H) FD 23 (9010-0194)20 l435 x 520 x 495 mm FD 56 (9010-0303)60 l560 x 565 x 625 mm FD 115 (9010-0305)116 l710 x 605 x 735 mm FD 260 (9010-0309)259 l810 x 825 x 940 mm FD 720 (9010-0311)741 l1,165 x 870 x 1,590 mm The FD 56 described here, with a capacity of 60 litres, is suitable as a supplementary unit for small to medium-sized batches. If this volume is insufficient, the FD 115 with a 116-litre capacity is the next size up; for significantly larger quantities, the FD 260 with a 259-litre capacity or the FD 720 with a 741-litre capacity are available for large-scale applications. At the lower end of the range is the compact FD 23 model with a 20-litre capacity, designed for very small sample volumes and a minimal footprint. Distinction from natural convection, Solid.Line and the FP and M equipment variants The FD 56 operates with forced air circulation. Its counterpart with natural convection is the ED 56: without an active fan, heating up takes considerably longer, but air movement inside the chamber remains minimal, which is advantageous for some samples. Those on a tighter budget who are satisfied with a temperature range up to 250 °C and a simpler timer controller without an LCD display will find the FD-S 56 from the Solid.Line range to be the more economical alternative with a comparable usable volume. If additional programmable temperature and time profiles are required, BINDER offers two higher-specification models above the FD 56 in size 56: the FP series (convection with programme functions) and the M series (convection with extensive programme functions), designated as the FP 56 and M 56 respectively. BINDER also uses the designation ‘Classic’ for certain smaller models.Line; as the current master data does not provide a consistent record of which LT items belong to this third line, no specific assignment is claimed here. An overview of the entire BINDER range available from LT Laborhandel can be found in the ‘Climate Chambers & Incubators’ category. Application, operation and maintenance The heating time to 150 °C is just 15 minutes; the spatial temperature deviation is 1.7 ± K and the temporal deviation is 0.3 ± K. With an air exchange rate of 80 times per hour at 100 °C, rapid, uniform drying is achieved even with a dense load. The sound pressure level of 43 dB(A) must be taken into account when installing the unit in a laboratory, particularly if it is in continuous operation in the immediate vicinity of workstations. The rated power of 1.1 kW is on a par with comparable forced-air drying cabinets of this size and must be taken into account when fusing the electrical circuit. Practical note: Standard, non-abrasive laboratory cleaning products are suitable for maintaining the interior; we advise against the use of abrasive or chlorine-based agents. Calibration is recommended for the regular checking of temperature accuracy; LT Laborhandel can supply suitable calibration certificates via its procurement service. No separately verified data is available for the FD 56 regarding the class of the temperature selector limiter; therefore, no statement is deliberately made on this matter. Investment rationale: When recirculation is sufficient, and when programme functions or natural convection are advisable For day-to-day laboratory routines involving recurring drying and sterilisation processes at a constant setpoint temperature, the FD 56 with its LCD controller reliably meets these requirements. If, on the other hand, multi-stage temperature profiles need to be run automatically and repeatably, the additional cost of the FP 56 or M 56 is often recouped through reduced manual intervention. If air movement inside the chamber is undesirable, the ED 56 with natural convection is the only option, even if this means accepting longer heating-up times. If a temperature range up to 250 °C is sufficient, the FD-S 56 from the Solid.Line range offers additional savings on the initial purchase cost, without compromising performance for most routine applications in drying and heat treatment. For higher loading densities, additional loading racks are available as accessories, as are calibration certificates and maintenance contracts of varying scope; both can be obtained via LT Laborhandel’s procurement service. Anyone who is still unsure whether the FD 56, FP 56 or M 56 is the more cost-effective choice for their intended application can also seek this assessment via the procurement service, rather than making a decision based solely on the data sheet specifications. Frequently asked questions about the Binder FD 56 What is the usable volume of the FD 56?60 litres, with external dimensions of 560 x 625 x 565 mm. What distinguishes the FD 56 from the ED 56 with natural convection?The FD 56 uses forced air circulation and therefore heats up significantly faster than the ED 56, which operates without a fan and avoids air movement inside the chamber. What distinguishes the FD 56 from the FD-S 56 in the Solid.Line range?The FD-S 56 covers a temperature range up to 250 °C and is controlled via a simpler timer controller; the FD 56 reaches up to 300 °C and features an LCD display. Is the FD 56 suitable for sterilisation processes?Yes, the temperature range up to 300 °C and the rapid, uniform convection heating make it suitable for sterilisation processes in quality assurance and research. How loud is the FD 56 when in operation?The sound pressure level is 43 dB(A). Is the FD 56 also available with a 120 V connection?Yes, in addition to the 230 V version, the unit is also available as a 120 V variant. What is included in the scope of delivery?The FD 56 (9010-0303), standard insert grilles and the user manual.
Memmert UN260 Universal Oven, large-capacity heating and drying oven with natural convection, 256 litres, up to 300 °C
With an internal volume of 256 litres, the Memmert UN260 universal oven is clearly a floor-standing unit designed for businesses that regularly heat-treat, dry or temper larger batches. Like the smaller models in the series, it operates using purely natural convection within a temperature range of 20 to 300 °C, but now across up to 9 shelves. For materials testing and quality assurance in industry, where several test series run simultaneously and vibration-free operation remains crucial, the UN260 marks the entry point into the large-volume models of the UN series.Natural convection on an industrial scaleEven with an internal volume of 256 litres, the Memmert UN260 universal oven does not require an air turbine or a forced-air motor. Heat rises purely by thermal convection, without a fan stirring up dust or light sample particles within the large interior. The operating temperature range starts at a minimum of 5 °C above room temperature and extends up to 300 °C. With up to 9 shelves occupied simultaneously, uniform natural heat distribution is particularly advantageous for sensitive or open-design material samples, for example in materials testing. A DIN Class A Pt100 temperature sensor with 4-wire measurement provides a setting accuracy of 0.1 °C up to 99.9 °C and 0.5 °C from 100 °C onwards, regardless of the unit size.ControlCOCKPIT SingleDISPLAY for everyday industrial useThe UN260 is operated via the ControlCOCKPIT SingleDISPLAY, an adaptive, multifunctional digital PID microprocessor controller with a high-resolution TFT colour graphic display. Settings include temperature in Celsius or Fahrenheit, the position of the exhaust air damper, programme duration, as well as time zone and summer/winter time. A digital countdown timer with target time can be set from 1 minute to 99 days; the SetpointWait function only starts the process time once the setpoint temperature has been reached, ensuring reproducible results for industrial batches lasting several hours. The data logger can be read out and managed via the Ethernet interface; a time-limited trial version of the AtmoCONTROL software is available for download.Capacity and dimensions of the Memmert UN260 universal chamberThe interior measures 640 x 800 x 500 mm, whilst the external dimensions are 824 x 1183 x 684 mm. Two electropolished stainless steel wire racks are included as standard; the cabinet can accommodate up to nine racks in total – more than any smaller UN model. The maximum load capacity is 300 kg for the entire unit and 20 kg per shelf. The interior consists of easy-to-clean stainless steel, reinforced with deep-drawn ribbing, featuring protected, integrated 4-sided all-round heating; the housing is made of textured stainless steel with a fully galvanised sheet steel rear panel. The UN260 is connected to 230 V (approx. 3,400 W) or 115 V (approx. 1,800 W), in both cases at 50/60 Hz, and remains single-phase despite the unit’s size.Selection guide: an introduction to the large-volume modelsThe Memmert UN series with natural convection ranges from 32 to 749 litres internal volume. The UN260 is the first model in the range that is specifically designed as a floor-standing unit, rather than a benchtop unit.ModelInternal volumeUN3032 l, footprint 585 x 434 mm, 3 shelves max.UN5553 l, footprint 585 x 514 mm, max. 4 shelvesUN7574 l, footprint 585 x 514 mm, max. 6 shelvesUN110108 l, footprint 745 x 584 mm, max. 5 shelvesUN260256 l, footprint 824 x 684 mm, max. 9 shelvesUN450449 l, footprint 1,224 x 784 mm, max. 8 shelvesUN750749 l, footprint 1,224 x 784 mm, max. 14 shelvesIf the 108-litre capacity of the Memmert UN110 universal cabinet is no longer sufficient, the UN260, with a capacity of 256 litres and a significantly larger footprint, is the next step up. For even larger industrial batches, the Memmert UN450 universal cabinet follows, with a capacity of 449 litres and a three-phase power connection. The entire range can be found under Climate Cabinets & Incubators.Distinction: natural convection versus forced air circulationWith a capacity of 256 litres and 9 shelves, it is worth considering whether active air circulation might not be more appropriate anyway. Forced-air models in the UF series feature an electronically controlled fan and actively distribute heat throughout the interior, which ensures shorter heating times for very densely packed batches of varying sizes – though only from 10 °C rather than 5 °C above room temperature. For materials sensitive to dust or air movement – such as in materials testing with open-layout samples – the natural convection of the UN260 remains the more technically suitable choice. A forced-air model of a similar size is the Memmert UF450 universal oven with a capacity of 449 litres. Like all standard models in the series, the UN260 uses the ControlCOCKPIT SingleDISPLAY; the TwinDISPLAY with two screens is reserved for the ‘plus’ variants.Safety in accordance with DIN 12880 for large, valuable batchesProcess reliability is crucial, particularly with a 256-litre load, which often runs for several hours or overnight. The UN260 features adjustable electronic temperature monitoring as well as a mechanical temperature limiter of protection class 1 in accordance with DIN 12880, which switches off the heating when the temperature reaches approximately 20 °C above the maximum cabinet temperature. A self-diagnostic system assists with fault-finding, and three freely selectable temperature values can be calibrated. The unit bears CE and EAC markings as well as a UL mark.Installation, operation and disposalFor operation, a minimum clearance of 15 cm from the wall and a maximum clearance of 20 cm from the ceiling must be maintained; a minimum clearance of 5 cm is sufficient on the sides from the wall or an adjacent unit. With a net weight of around 110 kg and a footprint of 824 x 684 mm, the UN260 requires a permanently designated installation site with a load-bearing floor. It may be installed at altitudes of up to 2,000 m above sea level at ambient temperatures of 5 °C to 40 °C and a relative humidity of no more than 80 per cent, non-condensing. Electrically, the UN260 is designed for overvoltage category II and pollution degree 2; it must only be transported in an upright position. At the end of its service life, the UN260, as an electrical appliance, is subject to the Electrical and Electronic Equipment Act and must not be disposed of with household waste.Typical areas of applicationWith an internal volume of 256 litres, up to 9 shelves and a load capacity of up to 300 kg, the Memmert UN260 universal chamber is designed for applications involving higher throughput and larger test batches.Heat treatment and drying of larger batches of material in industryRoutine tempering, ageing and baking of material samplesMaterial testing and quality assurance with high sample throughputVibration-free operation with large numbers of dust-sensitive test specimensA complement to laboratories upgrading from the UN110 to significantly greater capacityInvestment rationale: Equipment designed for continuous industrial operationThe UN260 is supplied with 2 electropolished stainless steel grating shelves as standard; the cabinet is designed to accommodate up to 9 shelves, each with a maximum load of 20 kg. Users who regularly utilise all levels should order additional grating or perforated sheets accordingly. For visual inspection without opening the door, a fully transparent glass door is available, along with interior lighting, an internal power socket and a levelling or mobile base frame. Those wishing to secure access can add a lockable door with a security lock. An AtmoCONTROL software licence is recommended for continuous data logging; for applications subject to standards, calibration and IQ/OQ/PQ services are available, including those accredited by DAkkS.Frequently asked questions before purchaseCan the UN260 still be operated on single-phase power?Yes, despite the size of the unit, the UN260 can be operated with either 230 V (approx. 3,400 W) or 115 V (approx. 1,800 W); a three-phase connection is only required from the UN450 upwards.How many samples can be loaded at the same time?Up to 9 trays, each with a maximum load of 20 kg, giving a total load capacity of up to 300 kg.How much floor space do I need to allow for?824 x 684 mm floor space, with a total height of 1,183 mm and a net weight of around 110 kg.Is natural convection still sufficient with so many trays?Yes, for most heat treatment and drying processes. For very densely loaded batches with widely varying sample sizes, a forced-air model such as the UF450 can operate more uniformly.What is the accuracy of the temperature control?With the UN260, too, it is 0.1 °C up to 99.9 °C and 0.5 °C from 100 °C onwards, measured using a DIN Class A Pt100 sensor with 4-wire technology – unchanged from the smaller models in the series.Is the UN260 suitable for unattended continuous operation?The mechanical temperature limiter, which complies with Protection Class 1 according to DIN 12880, switches off the heating element at an overtemperature of approximately 20 °C and is designed for long, unattended processes.Technical detailsAdjustable temperature range20 to 300 °COperating temperature rangeat least 5 °C above room temperature up to 300 °CTemperature setting accuracyup to 99.9 °C: 0.1 °C, from 100 °C: 0.5 °CTemperature sensorPt100, DIN Class A, 4-wire measurementInternal volume256 lInternal dimensions (W x H x D)640 x 800 x 500 mmExternal dimensions of housing (W x H x D)824 x 1183 x 684 mmNet weightapprox. 110 kgPower supply 230 V50/60 Hz, approx. 3,400 WConnection 115 V50/60 Hz, approx. 1,800 WMaximum number of trays9Slots included2Max. load on unit300 kgMax. load per shelf20 kgInterior materialStainless steel, 4-sided all-round heatingCasing materialTextured stainless steel, galvanised sheet steel rear panelControl systemControlCOCKPIT SingleDISPLAY, PID microprocessor controller, TFT colour graphic displayTimer1 minute to 99 days, digital countdown timerPermissible ambient temperature5 °C to 40 °CPermissible relative humiditymax. 80% rel., non-condensingMaximum installation height2,000 mCertificationsCE, EAC, UL marksContents1x Memmert UN260 universal cabinetFactory calibration certificate (calibration at 160 °C)Fully insulated stainless steel doors with 2-point locking (compression door seal)2x stainless steel grating, electropolishedRegulatory informationThe Memmert UN260 universal cabinet is registered with the Stiftung Elektro-Altgeräte Register (Stiftung EAR) under WEEE registration number DE 66812464.Customised requirements & procurement serviceOptions available for the UN260 include fully transparent glass doors, interior lighting and a power socket, a levelling or castor-mounted base frame, a lockable door with a security lock, as well as reinforced grating and perforated metal sheets.

Binder FD 260 drying and heating cabinet with forced air circulation, 230 V, 9010-0309
The Binder FD 260 from the FD Avantgarde.Line series is a forced-air drying and heating cabinet designed for applications requiring particularly rapid drying and sterilisation. A powerful fan ensures uniform temperature distribution throughout the entire chamber, whilst Binder’s APT.line technology guarantees high spatial and temporal temperature accuracy. With a chamber volume of 259 litres and a temperature range from 10 °C above room temperature up to 300 °C, the FD 260 covers a wide range of applications. The unit is designed for energy efficiency: according to the manufacturer, the FD 260 is up to 30 per cent more energy-efficient than standard units on the market. It is operated via a controller with an LCD display, and a USB port enables data logging. A Class 2 temperature selector limiter in accordance with DIN 12880, featuring a visual alarm, is already integrated. Precise temperature control and fast heating times At 150 °C, the FD 260 achieves a spatial temperature deviation of 1.9 ± K and a temporal deviation of 0.4 ± K. The heating time to 150 °C is approximately 19 minutes; once the door is opened, the setpoint temperature is reached again after about 5 minutes. At 100 °C, the air exchange rate is 9 air changes per hour, which is important for uniform and rapid drying. The integrated Class 2 temperature selector limiter in accordance with DIN 12880, featuring a visual alarm, offers additional process reliability, for example during unattended drying or sterilisation cycles. With a maximum load of 40 kg per tray or 270 kg total load, the FD 260 is also designed for heavier samples and material batches. Typical applications A drying and heating oven such as the FD 260 is typically used for drying laboratory glassware and sample material, for the heat treatment of material samples, and for sterilisation processes in quality assurance, research and industrial manufacturing. The homogeneous temperature distribution and the rapid thermal dynamics of the forced-air circulation system also make the unit suitable for time-critical testing and drying processes where reproducible, consistent results are essential. Operation, features and noise levels in everyday laboratory use The FD 260 is controlled via a controller with an LCD display and features a programme memory that allows recurring drying and sterilisation cycles to be stored. The exhaust air flap is controlled electromechanically, enabling the air exchange rate to be adjusted to suit the specific process. The scope of delivery includes two chrome-plated insert racks; if required, the interior can be expanded to accommodate up to eight racks. The ergonomic handle design facilitates operation in day-to-day laboratory work, and with a sound pressure level of just 43 dB(A), the unit operates pleasantly quietly even during continuous use. In terms of energy consumption, the FD 260 uses 245 Wh/h when operating at 100 °C and 410 Wh/h at 150 °C. Combined with what the manufacturer claims is up to 30 per cent greater energy efficiency compared to standard market models, this is particularly noticeable during frequent or continuous use in laboratory settings, such as during batch testing or in multi-shift operation.

Binder ED 56 Drying and Heating Oven, Avantgarde.Line with natural convection, 57 l, up to 300 °C, 9010-0333
A forced-air drying oven is not always the best choice for the warm storage or drying of samples that cannot tolerate air movement. The Binder ED 56 operates using natural convection rather than an active fan: the heat is distributed solely by thermal buoyancy within the chamber. With a usable volume of 57 litres and a temperature range from 5 °C above ambient temperature up to 300 °C, the ED 56 covers a wide range of applications within the Avantgarde.Line, without any of the air turbulence associated with a forced-air unit. Natural convection: slower, but gentler Without active air circulation, heating up takes longer than with a comparably sized forced-air model such as the FED 56, which has identical dimensions (heating time to 150 °C takes around 15 minutes for that model). With the ED 56, the heating-up time to 150 °C is around 50 minutes; once the door is opened, the setpoint temperature is reached again after approximately 19 minutes. In return, air movement inside the chamber remains minimal: an advantage for samples where turbulence or uneven airflow must be avoided. Controls, safety and data logging The ED 56 is controlled via a controller with an LCD display. A USB port enables the recording of process data. At 150 °C, the spatial temperature deviation is 2.3 ± K, the temporal deviation is 0.4 ± K, and energy consumption is 105 Wh/h (100 °C) and 180 Wh/h (150 °C) respectively. An integrated Class 2 temperature selector limiter in accordance with DIN 12880, featuring a visual alarm, provides additional process safety during unattended runs. Typical applications The ED 56 is suitable for drying and heating applications where air movement inside the chamber is undesirable or where a documented, reproducible process record is required. Drying of laboratory glassware and sample containers without air turbulence Warm storage of dust- or particle-sensitive materials Heat treatment with documented data recording via USB Routine operation in quality assurance and industrial laboratories With external dimensions of 560 x 565 x 625 mm and a weight of 39 kg, the ED 56 fits on most laboratory benches. Two chrome-plated shelf grids are included as standard.

Through our procurement service, LT Laborhandel will be happy to assist you with procurement and configuration. Selection guide within the range The Avantgarde.Line ED series with natural convection comprises six sizes at BINDER. All share the same temperature range, a controller with an LCD display and USB data logging, but differ significantly in terms of usable volume and footprint. Model sizeInternal volumeExternal dimensions (W x D x H) ED 23 (9010-0190)20 l435 x 520 x 495 mm ED 56 (9010-0333)57 l560 x 565 x 625 mm ED 115 (9010-0335)114 l710 x 605 x 705 mm ED 260 (9010-0339)255 l810 x 760 x 940 mm ED 400 (9010-0075)400 l1,235 x 765 x 1,025 mm ED 720 (9010-0341)743 l1,165 x 870 x 1,590 mm The ED 56 described here, with a capacity of 57 litres, is suitable for small to medium-sized batches on the laboratory bench. If this volume is insufficient, the next size up, the ED 115 with a capacity of 114 litres, is the obvious choice; for significantly larger batches, the ED 260 with a capacity of 255 litres is recommended. Differences between forced-air, Solid.Line and the FP and M equipment variants The most important distinction within the BINDER range is between natural convection and forced-air circulation: The ED 56 operates without an active fan; its forced-air counterpart with the same capacity is the FD 56. Forced-air heating heats up significantly faster (the FD 56 reaches 150 °C in around 15 minutes, compared with 50 minutes for the ED 56), but in doing so creates air movement inside the chamber, which is undesirable for some samples. Users who require programmable temperature and time profiles in addition to forced-air circulation will not find these functions in the ED series, but rather in the FP (forced-air circulation with programme functions) and M (forced-air circulation with extensive programme functions) series within the same BINDER range. For a smaller budget with a reduced temperature range up to 250 °C, the ED-S 56 is available within the Solid.Line range; this also features natural convection but comes with a simpler timer controller instead of the ED 56’s LCD display. BINDER also uses the designation ‘Classic’ for certain smaller models.Line; as the current master data does not provide a consistent record of which LT items belong to this third line, no specific classification is claimed here. An overview of the entire BINDER range at LT Laborhandel is provided in the ‘Climate Chambers & Incubators’ category. Application, Operation and Maintenance Without active air circulation, heating up to 150 °C takes around 50 minutes; after opening the door, the set temperature is reached again after approximately 19 minutes. Anyone using the cabinet for longer, unattended drying or heat treatment cycles can factor these times into their process planning. The spatial temperature deviation is 2.3 ± K, and the temporal deviation is 0.4 ± K. Process data can be downloaded via the USB port for documentation purposes, such as for batch records in quality assurance. Practical note: Standard, non-abrasive laboratory cleaning agents are suitable for cleaning the interior; we advise against using abrasive or chlorine-based products. The built-in Class 2 temperature selector limiter in accordance with DIN 12880, with a visual alarm, provides additional protection against accidental overheating during unattended runs. Calibration is recommended for regular checks of temperature accuracy; LT Laborhandel can arrange suitable calibration certificates via its procurement service. Investment rationale: When natural convection is sufficient, and when forced air or programme functions are advisable For samples where air movement inside the chamber is to be avoided, or where a documented process record via USB is required, the ED 56 is the right choice. If, on the other hand, the main priority is short cycle times and rapid, uniform drying of larger quantities, the forced-air circulation of the FD 56 comes into its own. If multi-stage temperature profiles need to run automatically, it is worth looking at the FP or M series with programme functions. If, on the other hand, a temperature range up to 250 °C and a simpler timer controller are sufficient, the Solid.Line with the ED-S 56 is the more economical option. The ED 56 comes as standard with two chrome-plated shelf grids. For higher loading densities, additional shelf grids are available as accessories, as are calibration certificates and maintenance contracts of varying scope – both available via LT Laborhandel’s procurement service. Frequently asked questions about the Binder ED 56 What is the internal capacity of the ED 56?57 litres, with external dimensions of 560 x 565 x 625 mm. What is the difference between the ED 56 and the FD 56?The ED 56 operates using natural convection without a fan, whilst the FD 56 uses forced air circulation. As a result, the FD 56 heats up significantly faster (around 15 minutes instead of 50 to reach 150 °C), whereas the ED 56 avoids air movement inside the chamber. What distinguishes the ED 56 from the larger ED 260?With a capacity of 255 litres, the ED 260 offers around four times the usable volume, with a correspondingly larger footprint; the operating principle is identical. What is the USB data logging function used for?The USB port allows process data from the drying or heat treatment cycle to be read out and documented, for example for batch records. Is the ED 56 also available with a 120 V connection?Yes, in addition to the 230 V version, the unit is also available as a 120 V variant. How do I clean the interior?Standard laboratory cleaners without abrasive properties are the right choice. Abrasive or chlorine-based agents must not be used inside the chamber (practical note). What is included in the scope of delivery?The ED 56 (9010-0333), two chrome-plated insert grids and the user manual.
Memmert UF260 Universal Oven, heating and drying oven with forced air circulation, 256 litres, up to 300 °C
The Memmert UF260 universal oven bridges the gap between compact benchtop units and the very large floor-standing models in the range: 256 litres of internal volume, a temperature range of 20 to 300 °C and an electronically controlled fan that ensures even heat distribution even when several batches are running simultaneously. With up to 9 shelves and a maximum total load capacity of 300 kg, the UF260 offers sufficient capacity for routine laboratory operations with varying sample quantities, without taking up the floor space of a floor-standing oven in the 449- or 749-litre class. It can be connected to either 230 V or 115 V, at 50/60 Hz in each case.Forced air circulation for even heat distribution in a medium-sized chamberThe UF260’s fan, which is electronically controllable in 10 per cent increments, actively distributes heat throughout the interior rather than allowing it to rise naturally, as is the case with a natural convection oven. As a result, the UF260 reliably achieves its operating temperature range – from at least 10 °C above room temperature up to 300 °C – even when several wire shelves are occupied simultaneously. A DIN Class A Pt100 temperature sensor with 4-wire measurement ensures a setting accuracy of 0.1 °C up to 99.9 °C and 0.5 °C from 100 °C onwards. Preheated fresh air is introduced via an electronically adjustable exhaust air damper; the exhaust air outlet with a throttle valve can also be controlled electronically.ControlCOCKPIT SingleDISPLAY: Operation, programming and data acquisitionThe UF260 is controlled via the ControlCOCKPIT SingleDISPLAY, an adaptive, multifunctional digital PID microprocessor controller with a high-resolution TFT colour graphic display. The following can be set: temperature in Celsius or Fahrenheit, the speed of the recirculation fan, the position of the exhaust air damper, the programme duration, as well as the time zone and summer/winter time. A digital countdown timer with target time can be set from 1 minute to 99 days; the SetpointWait function only starts the actual process time once the setpoint temperature has actually been reached. The integrated data logger can be read, managed and organised via the Ethernet interface; a time-limited trial version of the AtmoCONTROL software is available for download to help you get started.Capacity and dimensions of the Memmert UF260 universal chamberThe interior of the UF260 measures 640 x 800 x 500 mm and accommodates 2 electropolished stainless steel wire shelves as standard; up to 9 shelves can be fitted in total. The cabinet can be loaded with up to 300 kg; a maximum of 20 kg is permitted per shelf. The external dimensions of the cabinet are 824 x 1,183 x 684 mm, and the net weight is approximately 110 kg. The interior consists of easy-to-clean stainless steel, reinforced by deep-drawn ribbing, with protected, integrated 4-sided all-round heating; the housing is made of textured stainless steel with a fully galvanised sheet steel rear panel. Unlike the 449- and 749-litre models, the UF260 is not listed as a mobile version in the data sheet; it is designed for a fixed installation on a laboratory bench or base frame.Selection guide: choosing the right size from the UF rangeWithin the Memmert UF range, there is a difference of almost 1,000 litres in internal volume between the smallest and largest models, ranging from 53 to 1,060 litres. In addition to the volume, the footprint and the number of shelves required are key factors in making the right choice.ModelInternal volumeUF5553 l, footprint 585 x 514 mm, max. 4 shelvesUF7574 l, footprint 585 x 514 mm, max. 6 shelvesUF110108 l, footprint 745 x 584 mm, max. 5 shelvesUF160161 l, footprint 745 x 584 mm, max. 8 shelvesUF260256 l, footprint 824 x 684 mm, max. 9 shelvesUF450449 l, footprint 1,224 x 784 mm, max. 8 shelvesUF750749 l, footprint 1,224 x 784 mm, max. 14 shelvesUF10601,060 l, footprint 1,224 x 1,035 mm, max. 14 shelvesThe UF260 is the obvious choice when the Memmert UF160 universal cabinet (161 litres, same footprint as the UF110) reaches its capacity limit, but a significantly larger footprint is not yet available. Those requiring even more volume and additional mobility will find this in the Memmert UF450 universal cabinet (449 litres). All sizes in the range can be found in the LT Laborhandel range of climate cabinets and incubators.Distinction: TwinDISPLAY variant and natural convection counterpartThe UF260 described here operates with SingleDISPLAY and a single Pt100 sensor. For processes with higher safety requirements, such as unattended overnight runs, the Memmert UF260plus universal cabinet additionally offers a second Pt100 sensor for redundant monitoring, TwinDISPLAY with two displays, and the HeatBALANCE and AutoSAFETY functions. For those who can do without active air circulation – because dust-sensitive or airflow-sensitive samples are laid out in the open – the Memmert UN260 universal cabinet offers the same housing design but with natural convection instead of an air turbine.Safety in accordance with DIN 12880 for unattended operationIn addition to the adjustable electronic temperature monitoring, the UF260 features a mechanical temperature limiter of protection class 1 in accordance with DIN 12880, which switches off the heating element when the temperature reaches approximately 20 °C above the maximum cabinet temperature. An integrated self-diagnostic system assists with fault-finding, whilst the calibration function allows for the readjustment of three freely selectable temperature values. The unit bears CE and EAC markings as well as a UL mark.Installation, operation and disposalFor operation, a minimum clearance of 15 cm from the wall and a maximum clearance of 20 cm from the ceiling must be maintained; a minimum clearance of 5 cm from the side to the wall or an adjacent unit is sufficient. The unit may be installed at altitudes of up to 2,000 m above sea level at an ambient temperature of 5 °C to 40 °C and a relative humidity of no more than 80 per cent, non-condensing. Electrically, the UF260 is designed for overvoltage category II and pollution degree 2; it must only be transported in an upright position. The interior, made of easy-to-clean stainless steel, can be cleaned using standard laboratory cleaning agents. As an electrical appliance, the UF260 is subject to the Electrical and Electronic Equipment Act at the end of its service life and must not be disposed of with household waste; see Regulatory Information below.Typical areas of applicationWith an internal volume of 256 litres and active air circulation, the Memmert UF260 universal cabinet is suitable for laboratories that regularly run several batches simultaneously without the need to install a separate floor-standing cabinet.Drying several sample series in parallel during routine operationsTempering, ageing and baking of material samples in small batchesTesting and curing in quality assuranceMaterial testing in industrial manufacturingA second unit alongside a smaller UF model when the sample volume increasesInvestment rationale: Equipment tailored to the specific purposeThe UF260 is supplied with 2 electropolished stainless steel wire mesh shelves; the cabinet is designed to accommodate up to 9 shelves. Users who regularly load multiple levels simultaneously should order additional wire mesh shelves or perforated sheets. A fully transparent glass door is available as an option for visual inspection without opening the door, as are interior lighting, an internal power socket and a reversible door hinge. Those wishing to operate the UF260 unattended overnight whilst utilising the redundancy of a second temperature sensor with AutoSAFETY monitoring should opt for the Memmert UF260plus universal cabinet. A USB-to-Ethernet adapter and AtmoCONTROL software licences are available for continuous data logging. For pharmaceutical or standards-compliant applications, we arrange calibration, IQ/OQ/PQ and maintenance services, including those accredited by DAkkS.Frequently asked questions before purchaseHow many samples can the UF260 hold at any one time?Two wire shelves are included as standard; up to 9 inserts, each with a maximum load of 20 kg, are possible, giving a total load capacity of up to 300 kg.Is the UF260 on castors?No, the data sheet does not list any castors for this model; the UF260 is designed for a fixed location on a laboratory bench or base frame.Is SingleDISPLAY sufficient for routine operation?For most applications, yes. However, if you wish to run unattended overnight cycles with redundant temperature monitoring, the Memmert UF260plus universal chamber with TwinDISPLAY is a better choice.What is the accuracy of the temperature control?The DIN Class A Pt100 sensor operates using a 4-wire measurement and achieves an accuracy of 0.1 °C up to 99.9 °C; from 100 °C onwards, the accuracy is 0.5 °C.How does the UF260 differ from the smaller UF160?Both use the same forced-air circulation technology and SingleDISPLAY; however, the UF260 offers greater capacity with 256 litres instead of 161 litres and 9 shelves instead of 8, whilst occupying a larger footprint.Is a natural convection version available in this size?Yes, the Memmert UN260 universal cabinet shares the same housing as the UF260 but operates without an air turbine.Is the UF260 suitable for continuous operation overnight?The mechanical temperature limiter, which complies with Protection Class 1 according to DIN 12880, switches off the heating when the temperature exceeds the set point by approximately 20 °C and is designed for unattended operation.Technical detailsAdjustable temperature range20 to 300 °COperating temperature rangeat least 10 °C above room temperature up to 300 °CTemperature setting accuracyup to 99.9 °C: 0.1 °C, from 100 °C: 0.5 °CTemperature sensorPt100, DIN Class A, 4-wire measurementInternal volume256 lInternal dimensions (W x H x D)640 x 800 x 500 mmExternal dimensions of housing (W x H x D)824 x 1,183 x 684 mmNet weightapprox. 110 kgPower supply 230 V50/60 Hz, approx. 3,400 WConnection 115 V50/60 Hz, approx. 1,800 WMaximum number of trays9Slots included2Max. load on unit300 kgMax. load per shelf20 kgInterior materialStainless steel, 4-sided all-round heatingCasing materialTextured stainless steel, galvanised sheet steel rear panelControl systemControlCOCKPIT SingleDISPLAY, PID microprocessor controller, TFT colour graphic displayTimer1 minute to 99 days, digital countdown timerPermissible ambient temperature5 °C to 40 °CPermissible relative humiditymax. 80% relative, non-condensingMaximum installation altitude2,000 mCertificationsCE, EAC, UL approval marksContents of delivery1x Memmert UF260 universal cabinetFactory calibration certificate (calibration at 160 °C)Fully insulated stainless steel door with 2-point locking (compression door seal)2x stainless steel grating, electropolishedRegulatory informationThe Memmert UF260 universal cabinet is registered with the Stiftung Elektro-Altgeräte Register (Stiftung EAR) under WEEE registration number DE 66812464.Customised requirements & procurement serviceOptions available for the UF260 include full-view glass doors, interior lighting and a power socket, a reversible door hinge, lockable doors, a potential-free alarm contact and MobileALERT remote monitoring.

Memmert UF110 Universal Oven, compact heating and drying oven with forced circulation, 108 litres, up to 300 °C
For those wishing to upgrade from a small benchtop unit to a model with significantly greater capacity without having to install a floor-standing cabinet straight away, the Memmert UF110 universal cabinet offers the ideal intermediate solution: 108 litres’ internal volume, a temperature range of 20 to 300 °C and an electronically controlled fan for active heat distribution. With up to 5 shelves and a maximum total load capacity of 175 kg, the UF110 meets the needs of many laboratories that regularly dry or temper several small to medium-sized sample batches in parallel, without the cabinet taking up the floor space of a larger model.Forced air circulation instead of natural convection: faster heating timesThe UF110’s fan, which is electronically adjustable in 10 per cent increments, actively distributes heat throughout the interior, rather than simply allowing it to rise, as is the case with a natural convection oven. As a result, the UF110 reaches its operating temperature range from at least 10 °C above room temperature up to 300 °C, with shorter heating-up times than a comparable natural convection model, which achieves this without any air movement inside the chamber. A DIN Class A Pt100 temperature sensor with 4-wire measurement ensures a setting accuracy of 0.1 °C up to 99.9 °C and 0.5 °C from 100 °C onwards. Those running many different batches with varying setpoint temperatures will benefit from the active air circulation; dust-sensitive samples, on the other hand, are better suited to the natural convection version.ControlCOCKPIT SingleDISPLAY and data acquisitionThe UF110 is controlled via the ControlCOCKPIT SingleDISPLAY, an adaptive, multifunctional digital PID microprocessor controller with a high-resolution TFT colour graphic display. Settings include temperature in Celsius or Fahrenheit, the speed of the air circulation motor, the position of the exhaust air flap, the programme duration, as well as the time zone and summer/winter time. A digital countdown timer with target time can be set from 1 minute to 99 days; the SetpointWait function only starts the process time once the setpoint temperature has actually been reached. The data logger can be read out and managed via the Ethernet interface; a time-limited trial version of the AtmoCONTROL software is available for download.Capacity and dimensions of the Memmert UF110 universal chamberThe internal dimensions are 560 x 480 x 400 mm; the external dimensions of the housing are 745 x 864 x 584 mm, and the net weight is approximately 74 kg. Two electropolished stainless steel grids are included as standard; a total of up to five shelves can be fitted. The maximum total load is 175 kg, with a maximum of 20 kg per shelf. The interior is made of easy-to-clean stainless steel, reinforced with deep-drawn ribbing, and features protected, integrated 4-sided all-round heating; the housing is made of textured stainless steel with a fully galvanised sheet steel rear panel. The UF110 can be connected either to 230 V (approx. 2,800 W) or to 115 V (approx. 1,800 W), in each case at 50/60 Hz.Selection guide: choosing the right size from the UF rangeThe Memmert UF range offers eight models with internal volumes ranging from 53 to 1,060 litres. When selecting the right size, you should compare not only the volume but also the footprint and the maximum number of shelves.ModelInternal volumeUF5553 l, footprint 585 x 514 mm, max. 4 shelvesUF7574 l, footprint 585 x 514 mm, max. 6 shelvesUF110108 l, footprint 745 x 584 mm, max. 5 shelvesUF160161 l, footprint 745 x 584 mm, max. 8 shelvesUF260256 l, footprint 824 x 684 mm, max. 9 shelvesUF450449 l, footprint 1,224 x 784 mm, max. 8 shelvesUF750749 l, footprint 1,224 x 784 mm, max. 14 shelvesUF10601,060 l, footprint 1,224 x 1,035 mm, max. 14 shelvesThe UF110 is the obvious choice when the Memmert UF75 universal cabinet (74 litres, 6 shelves with a smaller footprint) becomes too small for the sample volume, but a larger footprint is not yet available. Anyone requiring more volume and more shelves whilst maintaining the same footprint will find what they need in the Memmert UF160 universal cabinet (161 litres, 8 shelves instead of 5, same footprint, but taller). All sizes in the range can be found in the LT Laborhandel range of climate cabinets and incubators.Distinction: TwinDISPLAY variant and natural convection counterpartThe UF110 described here operates with SingleDISPLAY and a single Pt100 sensor. Those requiring redundant temperature monitoring for unattended runs will find this in the Memmert UF110plus universal cabinet, which features two Pt100 sensors, TwinDISPLAY, HeatBALANCE and AutoSAFETY. Those who can do without active air circulation – for example, because dust-sensitive samples are laid out in the open – will find the Memmert UN110 universal chamber, which features the same housing design but uses natural convection instead of an air turbine.Safety in accordance with DIN 12880 for unattended operationIn addition to the adjustable electronic temperature monitoring, the UF110 features a mechanical temperature limiter of protection class 1 in accordance with DIN 12880, which switches off the heating when the temperature reaches approximately 20 °C above the maximum cabinet temperature – an important safety feature for runs carried out overnight or at weekends. An integrated self-diagnostic system assists with fault-finding, whilst the calibration function allows three freely selectable temperature values to be readjusted. The unit bears CE and EAC markings as well as a UL certification mark.Installation, operation and disposalFor the operation of the UF110, a minimum clearance of 15 cm from the wall and a maximum clearance of 20 cm from the ceiling must be maintained; a minimum clearance of 5 cm is sufficient on the sides from the wall or an adjacent unit. Installation is permitted at altitudes of up to 2,000 m above sea level, at an ambient temperature of 5 °C to 40 °C and a relative humidity of no more than 80 per cent, non-condensing. Electrically, the cabinet is designed for overvoltage category II and pollution degree 2; it must only be transported in an upright position. As an electrical appliance, the UF110 is subject to the Electrical and Electronic Equipment Act at the end of its service life and must not be disposed of with household waste; see Regulatory Information below.Typical applicationsWith an internal volume of 108 litres and active air circulation, the Memmert UF110 universal cabinet is suitable for laboratories that require more capacity than a standard benchtop unit but wish to remain compact.Drying of laboratory glassware and medium-sized sample batches in routine operationTempering, ageing and baking of material samplesTesting and curing in quality assuranceMaterial testing in the industrial manufacture of smaller componentsAs a secondary unit alongside a UF75 when the volume of samples increasesInvestment rationale: Equipment tailored to the specific purposeThe UF110 is supplied with 2 electropolished stainless steel wire mesh shelves; the cabinet is designed to accommodate up to 5 shelves.

Memmert UN55 Universal Oven, compact heating and drying oven with natural convection, 53 litres, up to 300 °C
For those who have outgrown the Memmert UN30 universal cabinet but do not yet wish to install a floor-standing cabinet, the Memmert UN55 universal cabinet is the obvious next size up: 53 litres’ internal volume with almost the same footprint, and still utilising natural convection rather than an active fan. The temperature range extends from 20 to 300 °C, and the housing is made of textured stainless steel. As there is no active air circulation inside the chamber, the UN55 remains the first choice where vibration-free operation and low dust levels are more important than a particularly short heating-up time – for example, when drying samples laid out in the open or fine powders in slightly larger quantities than with the UN30.Natural convection: greater volume, same operating principleLike the smaller UN30, the Memmert UN55 universal oven deliberately does without an air turbine and a forced-air motor. Heat rises within the chamber purely by convection, without a fan stirring up dust or light sample particles. Consequently, the operating temperature range starts from at least 5 °C above room temperature up to 300 °C, whilst the forced-air models of the UF series only start from 10 °C above room temperature, but heat up more quickly thanks to forced air circulation. A Pt100 temperature sensor of DIN Class A in a 4-wire configuration ensures a setting accuracy of 0.1 °C from 0 to 99.9 °C and 0.5 °C from 100 °C upwards, regardless of the unit size within the series.ControlCOCKPIT SingleDISPLAY and data acquisitionThe UN55 is controlled via the ControlCOCKPIT SingleDISPLAY, an adaptive, multifunctional digital PID microprocessor controller with a high-resolution TFT colour graphic display. Settings include temperature in Celsius or Fahrenheit, the position of the exhaust air damper, the programme duration, as well as time zone and summer/winter time; the parameter for a recirculation fan speed is omitted due to the design. A digital countdown timer with target time can be set from 1 minute to 99 days; the SetpointWait function only starts the process time once the setpoint temperature has actually been reached. The data logger can be read out and managed via the Ethernet interface; a time-limited trial version of the AtmoCONTROL software is available for download.Capacity and dimensions of the Memmert UN55 universal chamberThe interior measures 400 x 400 x 330 mm; the external dimensions are 585 x 784 x 514 mm, meaning it has the same footprint as the UN30 but is slightly taller. An electropolished stainless steel wire shelf is included; the cabinet can accommodate up to four shelves in total. The maximum load capacity is 80 kg for the entire unit and 20 kg per shelf. The interior consists of easy-to-clean stainless steel, reinforced by deep-drawn ribbing, with protected, integrated 4-sided all-round heating; the housing is made of textured stainless steel with a fully galvanised sheet steel rear panel. The UN55 is connected to 230 V (approx. 2,000 W) or 115 V (approx. 1,700 W), in each case at 50/60 Hz.Selection guide: choosing the right size from the UN seriesThe Memmert universal cabinet series with natural convection covers a range of internal volumes from 32 to 749 litres. When selecting the appropriate size, the key factors – in addition to the internal volume – are the footprint and the number of shelves required; not every larger model requires more floor space than the next smaller one.ModelInternal volumeUN3032 l, footprint 585 x 434 mm, max. 3 shelvesUN5553 l, footprint 585 x 514 mm, max. 4 shelvesUN7574 l, footprint 585 x 514 mm, max. 6 shelvesUN110108 l, footprint 745 x 584 mm, max. 5 shelvesUN260256 l, footprint 824 x 684 mm, max. 9 shelvesUN450449 l, footprint 1,224 x 784 mm, max. 8 shelvesUN750749 l, footprint 1,224 x 784 mm, max. 14 shelvesThe UN55 is the obvious choice when the UN30 (32 litres) becomes too small for the volume of samples to be processed, but a significantly larger footprint is not yet available. If you need even more shelves whilst maintaining the same footprint, the UN75 (74 litres, 6 shelves instead of 4, same footprint, just taller) is the solution. All seven sizes can be found in the LT Laborhandel range of climate cabinets and incubators.Differences: UN versus UF, and which display to chooseWithin the Memmert range of heating and drying cabinets, the most important purchasing decision is between natural convection (UN series) and forced air circulation (UF series). The UF models feature an electronically controlled fan, which actively distributes heat throughout the interior, thereby achieving shorter heating-up times; however, this only applies from 10 °C above room temperature, rather than from 5 °C as with the UN55. For samples sensitive to dust or air movement – such as loose powders or fibres – natural convection remains the more suitable choice. A direct forced-air equivalent of a similar size is the Memmert UF160 universal cabinet with a capacity of 161 litres. Those looking for an even more compact natural convection solution will find it in the Memmert UN30 universal cabinet with a capacity of 32 litres. All standard models in the UN series, including the UN55, are equipped with the ControlCOCKPIT SingleDISPLAY; the TwinDISPLAY variant, featuring two displays and additional safety and logging functions, is reserved for Memmert’s ‘plus’ models and is not part of this series.Safety in accordance with DIN 12880In addition to adjustable electronic temperature monitoring, the UN55 features a mechanical temperature limiter of protection class 1 in accordance with DIN 12880, which switches off the heating when the temperature reaches approximately 20 °C above the maximum cabinet temperature. A self-diagnostic system assists with fault-finding, and three freely selectable temperature values can be calibrated. The unit bears the CE and EAC markings as well as a UL certification mark.Installation, operation and disposalFor operation, a minimum distance of 15 cm from the wall and a maximum distance of 20 cm from the ceiling must be maintained; a minimum of 5 cm is sufficient on the sides relative to the wall or an adjacent unit. Installation is permitted at altitudes of up to 2,000 m above sea level at an ambient temperature of 5 °C to 40 °C and a relative humidity of no more than 80 per cent, non-condensing. Electrically, the UN55 is designed for overvoltage category II and pollution degree 2; it must only be transported in an upright position. The interior, made of easy-to-clean stainless steel, can be cleaned using standard laboratory cleaning products. As an electrical appliance, the UN55 is subject to the Electrical and Electronic Equipment Act at the end of its service life and must not be disposed of with household waste; see Regulatory Information below.Typical applicationsWith an internal volume of 53 litres and natural convection, the Memmert UN55 universal cabinet is suitable for laboratories that require slightly more capacity than a standard benchtop unit but still wish to operate in a vibration-free environment.Drying of laboratory glassware and medium-sized sample batchesVibration-free drying of dust- or air-sensitive samples and powdersTempering, ageing and baking of material samples in routine operationTesting and curing in quality assuranceAs a secondary unit alongside a UN30, as the volume of samples increasesInvestment rationale: Equipment tailored to the specific purposeThe UN55 is supplied with 1 electro-polished stainless steel wire mesh tray; the cabinet is designed to accommodate up to 4 trays. Those who regularly run several batches in parallel should order additional wire mesh shelves or perforated sheets. A fully transparent glass door is available as an option for visual inspection without opening the door – which reduces temperature fluctuations inside the chamber – as are interior lighting and an internal power socket for additional measuring equipment. Those wishing to use the data logger on a permanent basis, rather than just with the time-limited trial version, should add an AtmoCONTROL software licence and, if required, a USB-to-Ethernet adapter. For pharmaceutical or standard-compliant applications, calibration, IQ/OQ/PQ and maintenance services are available, including those accredited by DAkkS.Frequently asked questions before purchaseIs natural convection sufficient for uniform drying?For most routine applications, yes. For very densely packed batches with widely varying sample sizes, a forced-air model such as the UF160 distributes the heat more actively; for dust- or air-sensitive samples, the gentle natural convection of the UN55 is advantageous.How many samples can fit into the UN55 at once?One wire rack is included as standard; up to 4 trays, each with a maximum load of 20 kg, are possible, giving a total load capacity of up to 80 kg.Can I place the UN55 on a laboratory bench?Yes, with a net weight of around 57 kg and a footprint of 585 x 514 mm, the UN55 is designed for use on a laboratory bench, provided the bench can safely support the load.What is the accuracy of the temperature control?0.1 °C up to 99.9 °C and 0.5 °C from 100 °C onwards, as the UN55, like all models in the UN series, uses a DIN Class A Pt100 sensor with 4-wire technology.Can a glass door be fitted as an aftermarket option?A fully transparent glass door is one of the standard options for the UN55 and can be selected when placing your order.How does the UN55 differ from the smaller UN30?Both operate using natural convection and the same ControlCOCKPIT SingleDISPLAY; the UN55 offers greater capacity – 53 litres instead of 32 and 4 shelves instead of 3 – whilst occupying a similar footprint.Is the UN55 suitable for continuous overnight operation?The mechanical temperature limiter, which complies with Protection Class 1 according to DIN 12880, switches off the heating if the temperature rises by approximately 20 °C and is designed for unattended operation.Technical detailsAdjustable temperature range20 to 300 °COperating temperature rangeat least 5 °C above room temperature up to 300 °CTemperature setting accuracyup to 99.9 °C: 0.1 °C, from 100 °C: 0.5 °CTemperature sensorPt100, DIN Class A, 4-wire measurementInternal volume53 lInternal dimensions (W x H x D)400 x 400 x 330 mmExternal dimensions of housing (W x H x D)585 x 784 x 514 mmNet weightapprox. 57 kgConnection 230 V50/60 Hz, approx. 2,000 WConnection 115 V50/60 Hz, approx. 1,700 WMaximum number of trays4Slots included1Max. load on unit80 kgMax. load per shelf20 kgInterior materialStainless steel, 4-sided all-round heatingCasing materialTextured stainless steel, galvanised sheet steel rear panelControl systemControlCOCKPIT SingleDISPLAY, PID microprocessor controller, TFT colour graphic displayTimer1 minute to 99 days, digital countdown timerPermissible ambient temperature5 °C to 40 °CPermissible relative humiditymax. 80% rel., non-condensingMaximum installation height2,000 mCertificationsCE, EAC, UL certification marksContents of delivery1x Memmert UN55 universal cabinetFactory calibration certificate (calibration at 160 °C)Fully insulated stainless steel door with 2-point locking (compression door seal)1x stainless steel grating, electropolishedRegulatory informationThe Memmert UN55 universal cabinet is registered with the Stiftung Elektro-Altgeräte Register (Stiftung EAR) under WEEE registration number DE 66812464.Customised requirements & procurement serviceOptions available for the UN55 include fully transparent glass doors, interior lighting and a power socket, reinforced grating and perforated panels, slide-in or floor-standing drip trays, as well as wall brackets, levelling feet and a stacking kit.

Memmert UF750plus Universal Oven, large-capacity heating and drying oven with forced circulation and TwinDISPLAY, 749 litres, up to 300 °C, on castors
The Memmert UF750plus universal oven is designed for large-volume batches with high demands on process reliability: 749 litres’ internal capacity, a temperature range of 20 to 300 °C, and the same electronically controlled air turbine as the base model, supplemented by TwinDISPLAY with two redundant Pt100 sensors. If one of the two sensors fails, the second automatically takes over, providing added safety during long, unattended runs with valuable or time-critical batches. Fitted with castors that can be locked in place, the cabinet – weighing around 217 kg – can be moved around the laboratory or production hall despite its size.Circulating air with redundant temperature measurementThe UF750plus’s fan, which can be electronically controlled in 10 per cent increments, actively distributes heat throughout the large interior and reliably achieves the operating temperature range from at least 10 °C above room temperature up to 300 °C, even when fully loaded. Two DIN Class A Pt100 sensors in a 4-wire configuration monitor each other: if one sensor fails, the other takes over without the process having to be interrupted. The setting accuracy is 0.1 °C from 0 to 99.9 °C and 0.5 °C from 100 °C onwards. Preheated fresh air is introduced via an electronically adjustable exhaust air damper; the exhaust air outlet with throttle valve can also be controlled electronically.ControlCOCKPIT TwinDISPLAY: HeatBALANCE and AutoSAFETYThe UF750plus is controlled via the ControlCOCKPIT TwinDISPLAY, which features two high-resolution TFT colour graphic displays. The HeatBALANCE function allows for fine-tuning of the heat output distribution between the upper and lower heating groups from -50 to +50 per cent, for example to compensate for temperature differences caused by unevenly distributed loads. AutoSAFETY also monitors over- and under-temperature conditions, automatically tracks the setpoint within a freely selectable tolerance range, and triggers visual and audible alarms in the event of a deviation; if the setpoint is exceeded, the heating system switches off. Programmes are programmed, managed and transferred via the Ethernet interface or USB port using the AtmoCONTROL software. A programmable door lock and a door-open detection feature can be added as options – functions that are exclusive to TwinDISPLAY units.Capacity and connections of the Memmert UF750plus universal cabinetThe interior measures 1,040 x 1,200 x 600 mm and accommodates 2 electropolished stainless steel wire shelves as standard; up to 14 shelves are possible in total. A maximum total load of 300 kg and up to 30 kg per shelf are permitted. The external dimensions of the cabinet are 1,224 x 1,720 x 784 mm, and the net weight is approximately 217 kg, identical to that of the base model UF750. The interior consists of easy-to-clean stainless steel, reinforced by deep-drawn ribbing, with a protected, integrated 4-sided all-round heating system; the housing is made of textured stainless steel with a fully galvanised sheet steel rear panel. The UF750plus is connected to 400 V three-phase current and 3 x 230 V without a neutral conductor at 50/60 Hz, with a power consumption of around 7,000 W.Selection guide: choosing the right size from the UF rangeThe Memmert UF range with forced air circulation is available in eight sizes, with internal volumes ranging from 53 to 1,060 litres, each also available with TwinDISPLAY. When selecting the appropriate size, the key factors – in addition to the volume – are the footprint and the number of shelves required.ModelInternal volumeUF5553 l, footprint 585 x 514 mm, max. 4 shelvesUF7574 l, footprint 585 x 514 mm, max. 6 shelvesUF110108 l, footprint 745 x 584 mm, max. 5 shelvesUF160161 l, footprint 745 x 584 mm, max. 8 shelvesUF260256 l, footprint 824 x 684 mm, max. 9 shelvesUF450449 l, footprint 1,224 x 784 mm, max. 8 shelvesUF750749 l, footprint 1,224 x 784 mm, max. 14 shelvesUF10601,060 l, footprint 1,224 x 1,035 mm, max. 14 shelvesWithin this range, the UF750plus marks the boundary to the very large format, featuring TwinDISPLAY for enhanced process reliability. Those requiring even greater capacity will find it in the Memmert UF1060plus universal cabinet, offering 1,060 litres whilst maintaining the same footprint. All sizes in this range can be found in the LT Laborhandel range of climate cabinets and incubators.Key differences: TwinDISPLAY versus SingleDISPLAY, and natural convectionThose who can do without sensor redundancy and HeatBALANCE can save money with the identically constructed Memmert UF750 universal cabinet in the basic model with SingleDISPLAY. For samples sensitive to dust or air movement that cannot tolerate active air circulation, the Memmert UN750plus universal cabinet offers the same housing with natural convection instead of an air turbine, whilst retaining the TwinDISPLAY. A significantly more compact TwinDISPLAY model with an identical operating concept is the Memmert UF260plus universal cabinet with a capacity of 256 litres.Safety in accordance with DIN 12880, enhanced by AutoSAFETYIn addition to adjustable electronic temperature monitoring and AutoSAFETY, the UF750plus features a mechanical temperature limiter of protection class 1 in accordance with DIN 12880, which switches off the heating when the temperature reaches approximately 20 °C above the maximum cabinet temperature. The display also allows you to select either a temperature selector monitor (Protection Class 3.1) or a temperature selector limiter (Protection Class 2). An integrated self-diagnostic system assists with fault finding, and 3 freely selectable temperature values can be calibrated. The unit bears CE and EAC markings as well as a UL certification mark.Installation, operation and disposalFor operation, a minimum distance of 15 cm from the wall and a maximum distance of 20 cm from the ceiling must be maintained; a minimum distance of 5 cm from the wall or an adjacent unit on either side is sufficient. Installation is permitted at altitudes of up to 2,000 m above sea level at an ambient temperature of 5 °C to 40 °C and a relative humidity of no more than 80 per cent, non-condensing. Electrically, the cabinet is designed for overvoltage category II and pollution degree 2; it must only be transported in an upright position. Thanks to its castors, the UF750plus can still be moved within these specifications even after installation. As an electrical appliance, it is subject to the Electrical and Electronic Equipment Act at the end of its service life and must not be disposed of with household waste; see Regulatory Information below.Typical areas of applicationWith an internal volume of 749 litres and redundant sensor technology, the Memmert UF750plus universal cabinet is suitable for large-volume heat treatment processes with heightened requirements for process reliability.Unattended drying and tempering of large batches overnight or at weekendsMaterial testing in industrial manufacturing where documentation is requiredCuring and testing in quality assurance with a high volume of samplesHeat treatment processes in science and research with long process timesCentralised drying oven for multiple working groups with heightened safety requirementsInvestment rationale: when TwinDISPLAY is worthwhileThe UF750plus is supplied with 2 electropolished stainless steel grids; the cabinet is designed to accommodate up to 14 trays. TwinDISPLAY is particularly worthwhile where processes run unattended overnight or at weekends and where a sensor failure would otherwise jeopardise the entire batch, or where there is a documentation requirement supported by AutoSAFETY protocols. Those who do not require this redundancy can save money by opting for the Memmert UF750 universal cabinet in its basic model, which is of identical construction. A fully transparent glass door is available as an option for visual inspection without opening the door, as is a programmable door lock with door-open detection and a potential-free alarm contact for connection to a building management system. For pharmaceutical or standards-compliant applications, we arrange calibration, IQ/OQ/PQ and maintenance services, including those accredited by DAkkS.Frequently asked questions before purchaseWhat are the specific benefits of the second Pt100 sensor?If one sensor fails, the second one automatically takes over temperature monitoring; the process does not need to be interrupted, providing an added safety feature during long, unattended runs.What does the HeatBALANCE function do?It adjusts the distribution of heating power between the upper and lower heating groups from -50 to +50 per cent, for example to compensate for temperature differences caused by uneven loading.Is TwinDISPLAY worth it for routine operation?For simple drying tasks during the day, SingleDISPLAY is usually sufficient. For unattended runs overnight or where documentation is required, the UF750plus is the safer choice compared to the Memmert UF750 universal oven.How many shelves fit into the UF750plus?Two wire shelves are included as standard; up to 14 trays, each with a maximum load of 30 kg, are possible, giving a total load capacity of up to 300 kg.What power connection is required?400 V three-phase current with 3 x 230 V without a neutral conductor at 50/60 Hz and a power consumption of approximately 7,000 W.Is a natural convection version with TwinDISPLAY available?Yes, the Memmert UN750plus universal cabinet shares the same housing as the UF750plus, but operates without a fan.Is a programmable door lock available?Yes, a programmable door lock and door-open detection are options available exclusively for TwinDISPLAY units such as the UF750plus.Technical detailsAdjustable temperature range20 to 300 °COperating temperature rangeat least 10 °C above room temperature up to 300 °CTemperature setting accuracyup to 99.9 °C: 0.1 °C, from 100 °C: 0.5 °CTemperature sensor2x Pt100, DIN Class A, 4-wire measurement, redundantInternal volume749 lInternal dimensions (W x H x D)1,040 x 1,200 x 600 mmExternal dimensions of housing (W x H x D)1,224 x 1,720 x 784 mmNet weightapprox. 217 kgConnection400 V and 3 x 230 V neutral, 50/60 Hz, approx. 7,000 WMaximum number of racks14Drawers included2Max. load on unit300 kgMax. load per drawer30 kgInterior materialStainless steel, 4-sided all-round heatingCasing materialTextured stainless steel, galvanised sheet steel rear panelControl systemControlCOCKPIT TwinDISPLAY, PID microprocessor controller, 2x TFT colour graphic displaysAdditional functionsHeatBALANCE, AutoSAFETY, visual and audible alarmInstallationMobile and lockable on castorsPermissible ambient temperature5 °C to 40 °CPermissible relative humiditymax. 80% rel., non-condensingMaximum installation height2,000 mCertificationsCE, EAC, UL marksContents of delivery1x Memmert UF750plus universal cabinetFactory calibration certificate (calibration at 160 °C)Fully insulated stainless steel doors with 2-point locking (compression door seal)2x stainless steel grating, electropolishedRegulatory informationThe Memmert UF750plus universal cabinet is registered with the Stiftung Elektro-Altgeräte Register (Stiftung EAR) under WEEE registration number DE 66812464.Customised requirements & procurement serviceOptions available for the UF750plus include fully transparent glass doors, interior lighting and a power socket, a gas-tight interior, a potential-free alarm contact, MobileALERT remote monitoring, and a USB user ID stick for TwinDISPLAY user rights.

Memmert UF75 Universal Oven, compact heating and drying oven with forced air circulation, 74 litres, up to 300 °C
Anyone who finds the smallest model in the forced-air series has reached its capacity limit will find the next size up in the Memmert UF75 universal cabinet, which has almost the same footprint: 74 litres’ internal volume, a temperature range of 20 to 300 °C, and the same electronically controlled air turbine for active heat distribution. With up to 6 shelves instead of 4 compared to the smaller UF55, more batches can be run simultaneously without the cabinet taking up noticeably more floor space in the laboratory; it is simply slightly taller.Forced air circulation: greater capacity with the same footprintThe UF75’s air turbine, which is electronically adjustable in 10 per cent increments, actively distributes heat throughout the interior, rather than simply allowing it to rise as in a natural convection oven. As a result, the UF75 achieves its operating temperature range from at least 10 °C above room temperature up to 300 °C with shorter heating-up times than the structurally identical natural convection model UN75, which, by contrast, starts at just 5 °C above room temperature. A Pt100 temperature sensor of DIN Class A in a 4-wire configuration ensures a setting accuracy of 0.1 °C up to 99.9 °C and 0.5 °C from 100 °C onwards, regardless of the load on the up to 6 shelves.ControlCOCKPIT SingleDISPLAY and data acquisitionThe UF75 is controlled via the ControlCOCKPIT SingleDISPLAY, an adaptive, multifunctional digital PID microprocessor controller with a high-resolution TFT colour graphic display. Settings include temperature in Celsius or Fahrenheit, the speed of the recirculation fan, the position of the exhaust air damper, the programme duration, as well as the time zone and summer/winter time. A digital countdown timer with target time can be set from 1 minute to 99 days; the SetpointWait function only starts the process time once the setpoint temperature has actually been reached. The data logger can be read out and managed via the Ethernet interface; a time-limited trial version of the AtmoCONTROL software is available for download.Capacity and dimensions of the Memmert UF75 universal chamberThe interior measures 400 x 560 x 330 mm; the external dimensions of the housing are 585 x 944 x 514 mm, and the net weight is approximately 66 kg. Two electropolished stainless steel grids are included as standard; up to six shelves can be fitted in total. The maximum total load is 120 kg, with a maximum of 20 kg per shelf. The interior consists of easy-to-clean stainless steel, reinforced by deep-drawn ribbing, with protected, integrated 4-sided all-round heating; the housing is made of textured stainless steel with a fully galvanised sheet steel rear panel. The UF75 can be connected either to 230 V (approx. 2,500 W) or 115 V (approx. 1,800 W), in each case at 50/60 Hz.Selection guide: choosing the right size from the UF rangeWith eight sizes, the Memmert UF range covers an internal volume range from 53 to 1,060 litres. When selecting the appropriate size, the key factors – in addition to volume – are the footprint and the number of shelves required.ModelInternal volumeUF5553 l, footprint 585 x 514 mm, max. 4 shelvesUF7574 l, footprint 585 x 514 mm, max. 6 shelvesUF110108 l, footprint 745 x 584 mm, max. 5 shelvesUF160161 l, footprint 745 x 584 mm, max. 8 shelvesUF260256 l, footprint 824 x 684 mm, max. 9 shelvesUF450449 l, footprint 1,224 x 784 mm, max. 8 shelvesUF750749 l, footprint 1,224 x 784 mm, max. 14 shelvesUF10601,060 l, footprint 1,224 x 1,035 mm, max. 14 shelvesThe UF75 is the obvious choice when the Memmert UF55 universal cabinet (53 litres) becomes too small for the sample volumes involved, but a significantly larger footprint is not yet available. Those requiring more volume with a larger footprint will find this in the Memmert UF110 universal cabinet (108 litres, more internal space, slightly larger footprint). You can find all sizes in this range in the LT Laborhandel range of climate chambers and incubators.Key distinctions: forced air circulation versus natural convection, and TwinDISPLAYWithin the Memmert heating and drying cabinet range, the most important purchasing decision is between forced air circulation and natural convection. Thanks to its air turbine, the UF75 achieves shorter heating-up times than the structurally identical Memmert UN75 universal cabinet; however, for samples sensitive to dust or air movement, natural convection remains the more suitable choice. For unattended runs with redundant temperature monitoring, the Memmert UF75plus universal oven is available, featuring TwinDISPLAY, two Pt100 sensors, HeatBALANCE and AutoSAFETY. Those who require less capacity will find the Memmert UF55 universal oven to be the more compact alternative with the same footprint.Safety in accordance with DIN 12880 for unattended operationIn addition to adjustable electronic temperature monitoring, the UF75 features a mechanical temperature limiter of protection class 1 in accordance with DIN 12880, which switches off the heating when the temperature reaches approximately 20 °C above the maximum cabinet temperature. A self-diagnostic system assists with fault-finding, and three freely selectable temperature values can be calibrated. The unit bears CE and EAC markings as well as a UL test mark.Installation, operation and disposalFor operation, a minimum distance of 15 cm from the wall and a maximum distance of 20 cm from the ceiling must be maintained; a minimum of 5 cm is sufficient on the sides relative to the wall or an adjacent unit. It may be installed at altitudes of up to 2,000 m above sea level at an ambient temperature of 5 °C to 40 °C and a relative humidity of no more than 80 per cent, non-condensing. Electrically, the UF75 is designed for overvoltage category II and pollution degree 2; it must only be transported in an upright position. The interior, made of easy-to-clean stainless steel, can be maintained using standard laboratory cleaning products. As an electrical appliance, the UF75 is subject to the Electrical and Electronic Equipment Act at the end of its service life and must not be disposed of with household waste; see Regulatory Information below.Typical applicationsWith an internal volume of 74 litres and up to 6 shelves, the Memmert UF75 universal cabinet is suitable for laboratories that require slightly more capacity than the smallest UF model without taking up any additional floor space.Drying of laboratory glassware and medium-sized sample batches in routine operationTempering, ageing and baking of material samples in multiple batchesTesting and curing in quality assuranceMaterial testing in the industrial manufacture of smaller componentsAs a secondary unit alongside a UF55 when additional shelves are requiredInvestment rationale: Equipment tailored to the specific purposeThe UF75 is supplied with 2 electropolished stainless steel wire shelves; the cabinet is designed to accommodate up to 6 shelves.

Memmert UF1060 Universal Oven, the largest model in the UF range with forced convection, 1,060 litres, up to 300 °C, on castors
With a capacity of 1,060 litres, the Memmert UF1060 universal oven is the largest model in the entire UF range and is designed for batches that cannot be accommodated even in the 749-litre floor-standing model. The temperature range extends from 20 to 300 °C, and the electronically controlled air turbine actively distributes the heat throughout the spacious interior. A notable feature is the permissible load per shelf of up to 60 kg – three times that of the smaller UF models – which makes the UF1060 suitable for heavy workpieces and components. Fitted with castors that can be moved and locked, the cabinet – which weighs around 252 kg – can be moved around the laboratory or production hall despite its size.Forced air circulation in the largest model of the seriesWith an internal volume of 1,060 litres, active air circulation is practically essential for even heat distribution. The UF1060’s air turbine, which can be electronically controlled in 10 per cent increments, ensures that the operating temperature range – from at least 10 °C above room temperature up to 300 °C – is reliably achieved, even with densely packed, heavy batches. A DIN Class A Pt100 temperature sensor with a 4-wire measurement system provides a setting accuracy of 0.1 °C up to 99.9 °C and 0.5 °C from 100 °C upwards, regardless of the load. Preheated fresh air is introduced via an electronically adjustable exhaust air damper; the exhaust air outlet with throttle valve can also be controlled electronically.ControlCOCKPIT SingleDISPLAY for industrial useThe UF1060 is controlled via the ControlCOCKPIT SingleDISPLAY, an adaptive, multifunctional digital PID microprocessor controller with a high-resolution TFT colour graphic display. The following can be set: temperature in Celsius or Fahrenheit, the speed of the recirculation fan, the position of the exhaust air damper, the programme duration, as well as the time zone and summer/winter time. A digital countdown timer with target time can be set from 1 minute to 99 days; the SetpointWait function only starts the actual process time once the setpoint temperature has actually been reached – an important feature for long, unattended processes involving large batches. The integrated data logger can be read out, managed and organised via the Ethernet interface; a time-limited trial version of the AtmoCONTROL software is available for download.Capacity and load-bearing capacity of the Memmert UF1060 universal chamberThe interior measures 1,040 x 1,200 x 850 mm and accommodates 2 electropolished stainless steel wire shelves as standard; a total of up to 14 shelves are possible, as with the UF750. The key difference lies in the load capacity: Whilst the UF750 permits 30 kg per shelf, the UF1060 allows up to 60 kg per shelf, whilst still maintaining a total load capacity of 300 kg. The external dimensions of the cabinet are 1,224 x 1,720 x 1,035 mm, and the net weight is approximately 252 kg. The interior consists of easy-to-clean stainless steel, reinforced with deep-drawn ribbing, featuring protected, integrated 4-sided all-round heating; the housing is made of textured stainless steel with a fully galvanised sheet steel rear panel. The UF1060 is connected to a 400 V three-phase supply and 3 x 230 V without a neutral conductor at 50/60 Hz, with a power consumption of around 7,000 W.Selection guide: choosing the right size from the UF rangeThe Memmert UF range with forced-air circulation covers eight sizes, from 53 to 1,060 litres. When selecting the appropriate size, the footprint and the number of shelves required are key factors, alongside the internal volume itself.ModelInternal volumeUF5553 l, footprint 585 x 514 mm, max. 4 shelvesUF7574 l, footprint 585 x 514 mm, max. 6 shelvesUF110108 l, footprint 745 x 584 mm, max. 5 shelvesUF160161 l, footprint 745 x 584 mm, max. 8 shelvesUF260256 l, footprint 824 x 684 mm, max. 9 shelvesUF450449 l, footprint 1,224 x 784 mm, max. 8 shelvesUF750749 l, footprint 1,224 x 784 mm, max. 14 shelvesUF10601,060 l, footprint 1,224 x 1,035 mm, max. 14 shelvesThe UF1060 sits at the top end of this range and offers the largest available capacity within the series. With the same footprint as the Memmert UF750 universal cabinet (1,224 × 784 mm base area), its greater depth provides around 300 litres more internal capacity and three times the load capacity per shelf. Those who can make do with 749 litres and 30 kg per shelf will save on depth and purchase costs with the UF750. All sizes in the range can be found in the LT Laborhandel range of climate cabinets and incubators.Differentiation: SingleDISPLAY, TwinDISPLAY and natural convectionThe UF1060 described here operates with SingleDISPLAY and a single Pt100 sensor. For unattended processes with higher safety requirements, the Memmert UF1060plus universal cabinet offers two redundant Pt100 sensors, the HeatBALANCE function and additional AutoSAFETY monitoring, each with two TFT displays instead of one. Memmert does not offer a natural convection variant of this size in the UN series as a 1,060-litre model; the largest natural convection model is the Memmert UN750 universal cabinet with a capacity of 749 litres. Those looking for a smaller forced-air alternative with the same footprint will find it in the Memmert UF750 universal cabinet.Safety in accordance with DIN 12880 for unattended operationIn addition to the adjustable electronic temperature monitoring, the UF1060 features a mechanical temperature limiter of protection class 1 in accordance with DIN 12880, which switches off the heating when the temperature reaches approximately 20 °C above the maximum cabinet temperature – an important safety feature for overnight or weekend runs. An integrated self-diagnostic system assists with fault-finding, whilst the calibration function allows three freely selectable temperature values to be readjusted. The unit bears the CE and EAC markings as well as a UL mark.Installation, operation and disposalFor operation, a minimum distance of 15 cm from the wall and a maximum distance of 20 cm from the ceiling must be maintained; a minimum distance of 5 cm from the side of the wall or an adjacent unit is sufficient. Installation is permitted at altitudes of up to 2,000 m above sea level at an ambient temperature of 5 °C to 40 °C and a relative humidity of no more than 80 per cent, non-condensing. Electrically, the cabinet is designed for overvoltage category II and pollution degree 2; it must only be transported in an upright position. Thanks to its castors, the UF1060 can still be moved within these specifications even after installation. As an electrical appliance, it is subject to the Electrical and Electronic Equipment Act at the end of its service life and must not be disposed of with household waste; see Regulatory Information below.Typical applicationsWith an internal volume of 1,060 litres, a load capacity of up to 60 kg per shelf and mobility on castors, the Memmert UF1060 universal cabinet is designed for particularly large or heavy batches.Drying and tempering of large, heavy components in industrial manufacturingCuring and baking of material samples in large quantities or of large dimensionsHigh-throughput material testing in quality assuranceCentral drying cabinet for several workgroups requiring maximum capacityHeat treatment processes in science and research involving large-volume test specimensInvestment rationale: Equipment tailored to the specific purposeThe UF1060 is supplied with 2 electro-polished stainless steel grates; the cabinet is designed to accommodate up to 14 shelves, each with a load capacity of up to 60 kg. Users who regularly utilise all levels should order additional grates or perforated sheets. A fully transparent glass door is available as an option for visual inspection without opening the door, as are interior lighting, an internal socket and a gas-tight interior for applications requiring a controlled atmosphere. Those who run unattended cycles overnight or at weekends and wish to benefit from the additional redundancy of a second temperature sensor with AutoSAFETY monitoring are better served by the Memmert UF1060plus universal cabinet. A USB-to-Ethernet adapter and AtmoCONTROL software licences are available for continuous logging. For pharmaceutical or standard-compliant applications, we arrange calibration, IQ/OQ/PQ and maintenance services, including those accredited by DAkkS.Frequently asked questions before purchaseWhat is the maximum weight per shelf for individual workpieces?Up to 60 kg per tray, with a maximum total load of 300 kg for the cabinet.How many shelves fit into the UF1060?Two wire shelves are included as standard; up to 14 shelves are possible in total.Can the cabinet be moved whilst in use?Yes, the UF1060 is mounted on castors that can be locked in place and, despite its net weight of around 252 kg, can be moved within the permitted installation conditions.What power connection is required?The UF1060 requires 400 V three-phase current with 3 x 230 V without a neutral conductor at 50/60 Hz and has a power consumption of around 7,000 W.What distinguishes the UF1060 from the UF750?Both offer up to 14 racks on the same footprint; however, due to its greater depth, the UF1060 has a larger internal volume (1,060 litres instead of 749 litres) and allows double the load per rack (60 kg instead of 30 kg).Is a TwinDISPLAY version available?Yes, the Memmert UF1060plus universal cabinet also features two redundant Pt100 sensors, HeatBALANCE and AutoSAFETY, for unattended processes with higher safety requirements.Is the UF1060 suitable for continuous operation overnight?The mechanical temperature limiter, which complies with Protection Class 1 according to DIN 12880, switches off the heating element in the event of an overtemperature of approximately 20 °C and is designed for unattended operation.Technical detailsAdjustable temperature range20 to 300 °COperating temperature rangeat least 10 °C above room temperature up to 300 °CTemperature setting accuracyup to 99.9 °C: 0.1 °C, from 100 °C: 0.5 °CTemperature sensorPt100, DIN Class A, 4-wire measurementInternal volume1,060 lInternal dimensions (W x H x D)1,040 x 1,200 x 850 mmExternal dimensions of housing (W x H x D)1,224 x 1,720 x 1,035 mmNet weightapprox. 252 kgConnection400 V and 3 x 230 V neutral, 50/60 Hz, approx. 7,000 WMaximum number of shelves14Drawers included2Max. load capacity300 kgMax. load per drawer60 kgInner chamber materialStainless steel, 4-sided all-round heatingCasing materialTextured stainless steel, galvanised sheet steel rear panelControl systemControlCOCKPIT SingleDISPLAY, PID microprocessor controller, TFT colour graphic displayTimer1 minute to 99 days, digital countdown timerInstallationCan be moved and locked in place on castorsPermissible ambient temperature5 °C to 40 °CPermissible relative humiditymax. 80% relative, non-condensingMaximum installation height2,000 mCertificationsCE, EAC, UL certification marksContents of supply1x Memmert UF1060 universal cabinetFactory calibration certificate (calibration at 160 °C)Fully insulated stainless steel doors with 2-point locking (compression door seal)2x stainless steel grating, electropolishedRegulatory informationThe Memmert UF1060 universal cabinet is registered with the Stiftung Elektro-Altgeräte Register (Stiftung EAR) under WEEE registration number DE 66812464.Customised requirements & procurement serviceOptions available for the UF1060 include fully transparent glass doors, interior lighting and a socket, a gas-tight interior, reinforced grating and perforated sheets, lockable doors, a potential-free alarm contact and MobileALERT remote monitoring.

Binder FED 400 drying and heating oven, Avantgarde.Line with forced air circulation and extended timing functions, 400 l, up to 300 °C, 9010-0216
The Binder FED 400 is one of the larger models in the Avantgarde.Line FED series and offers a 400-litre usable volume with a temperature range from 5 °C above ambient temperature up to 300 °C. Unlike the smaller FED models 56, 115 and 260, which are designed for applications with a lower limit of 10 °C above ambient temperature, the FED 400 operates from as low as 5 °C above ambient temperature, making it suitable for a slightly wider temperature range. Like the entire FED range, it is designed for programmable, documented drying, sterilisation and heat treatment processes for larger batches. For laboratories and production areas that have previously operated several smaller drying cabinets in parallel, the FED 400 consolidates this capacity into a single, programmable unit with significantly reduced operational effort. Convection and temperature accuracy in a large chamber An adjustable fan, together with APT.line technology and the preheating chamber technology, ensures the most homogeneous temperature distribution possible within the large interior. At 150 °C, the FED 400 achieves a spatial temperature deviation of 3.8 ± K and a temporal deviation of 0.7 ± K. The heating time to 150 °C is approximately 29 minutes; after the door has been open for 30 seconds, the setpoint temperature is reached again after approximately 6 minutes. With an air change rate of 18 times per hour at 150 °C, even when the large interior is heavily loaded, uniform air circulation is ensured without the formation of pockets of moisture in individual areas of the chamber. Compared with the ED 400 of identical design but without forced air circulation (heating time around 71 minutes), this clearly demonstrates the time saving offered by forced air circulation in this size of unit. For processes requiring several batches per day, this difference can be decisive in determining the actual number of runs achievable. Programming, interfaces and safety The controller, with its advanced timing functions, allows drying or sterilisation cycles to be programmed and stored in the programme memory, so that recurring processes do not need to be reset each time. Both an Ethernet interface and an RS 422 computer interface are available for connection to external systems, ensuring that the FED 400 remains compatible even in environments with older process control technology. An integrated Class 2 temperature selector limiter in accordance with DIN 12880, featuring a visual alarm, provides additional safety for unattended process runs, which is particularly relevant given the 400-litre chamber size and the correspondingly high value of goods per batch. The exhaust air flap is adjustable and can be manually adapted to the specific drying or heat treatment process, for example to specifically extract more air when drying solvent-containing samples. Power rating and installation As this size requires more power than the smaller FED models, the FED 400 is designed to operate either on 400 V three-phase current or 208 V three-phase current, with a rated power of 3.4 kW and a 16 A circuit breaker. With external dimensions of 1,235 x 765 x 1,025 mm and a weight of 145 kg, the FED 400 is designed as a free-standing unit and should be taken into account when planning its installation, particularly with regard to floor load and access to the three-phase power supply. Compared with the ED 400, which is identical in size, the FED 400 weighs around 20 kg more due to its fan and control technology; this should be taken into account when planning the installation site. Typical applications With a capacity of 400 litres, the FED 400 is suitable for larger batches where both rapid heating via forced air circulation and programmable, documented process sequences are required – for example, when large quantities of sample material or components need to be processed regularly according to a reproducible time and temperature profile, and the results must remain comparable across multiple runs. Time-controlled drying of large quantities of laboratory glassware, components or packaging material Sterilisation processes for larger batches with temperature profiles requiring documentation Heat treatment of material samples in quality assurance according to a pre-set programme Routine operation in industrial and research laboratories with high throughput and documentation requirements Two chrome-plated insert racks are included as standard; these are designed to fit the large interior and allow the chamber to be divided for different batches or sample types within the same process run.
