Memmert UF110 universal oven, compact heating and drying oven with forced air circulation, 108 litres, up to 300 °C

Anyone 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, will find the Memmert UF110 universal oven to be the obvious intermediate option: 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 pure convection: faster heating times

The UF110’s air turbine, which can be electronically controlled in 10 % increments, actively distributes heat throughout the interior, rather than simply allowing it to rise, as is the case with a natural convection cabinet. As a result, the UF110 achieves 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, by contrast, operates entirely without any air movement inside the chamber. 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. Those who run 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 variant.

ControlCOCKPIT SingleDISPLAY and data acquisition

The UF110 is controlled via the ControlCOCKPIT SingleDISPLAY, an adaptive, multifunctional digital PID microprocessor controller with a high-resolution TFT colour graphics display. The following parameters can be adjusted: 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 UF110 universal oven

The interior measures 560 x 480 x 400 mm; the external dimensions of the cabinet are 745 x 864 x 584 mm, and the net weight is approximately 74 kg. Two electropolished stainless steel grid shelves are included as standard; up to five shelves can be fitted in total. The maximum total load is 175 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 UF110 can be connected either to 230 V (approx. 2,800 W) or to 115 V (approx. 1,800 W), in both cases at 50/60 Hz.

Selection guide: choosing the right size from the UF range

The Memmert UF range is available in eight sizes, with internal volumes ranging from 53 to 1,060 litres. When looking for the right size, you should compare not only the volume but also the footprint and the maximum number of shelves.

The UF110 is the obvious choice when the Memmert UF75 universal oven (74 litres, 6 shelves in a smaller footprint) becomes too small for the sample volume, but a larger footprint is not yet available. If you require more volume and more shelves whilst maintaining the same footprint, the Memmert UF160 universal oven (161 litres, 8 shelves instead of 5, same footprint, but taller) is the solution. You can find all sizes in this range in our Climate Chambers & Incubators product range.

Distinction: TwinDISPLAY version and its natural convection counterpart

The UF110 described here operates with SingleDISPLAY and a single Pt100 sensor. Anyone requiring redundant temperature monitoring for unattended runs will find this in the Memmert UF110plus universal oven with two Pt100 sensors, TwinDISPLAY, HeatBALANCE and AutoSAFETY. Anyone who can do without active air circulation, for example, because dust-sensitive samples are laid out in the open, will find in the Memmert UN110 universal oven the identical housing with natural convection instead of a fan.

Safety according to DIN 12880 for unattended operation

In addition to the adjustable electronic temperature monitoring, the UF110 features a mechanical temperature limiter of protection class 1 according to DIN 12880, which switches off the heating when the temperature rises to 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.

Installation, operation and disposal

When operating the UF110, a minimum clearance of 15 cm from the wall and a minimum clearance of 20 cm from the ceiling must be maintained; at the sides, a clearance of at least 5 cm from 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 %, 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 applications

With an internal volume of 108 litres and active air circulation, the Memmert UF110 universal oven is suitable for laboratories that require more capacity than a standard benchtop unit can provide, but still wish to keep their setup compact.

• Drying of laboratory glassware and medium-sized sample batches in routine operations
• Tempering, ageing and stoving of material samples
• Testing and curing in quality assurance
• Material testing in the industrial manufacture of small components
• A second unit alongside a UF75, as the sample volume increases

Investment rationale: Equipment tailored to the specific purpose

The scope of delivery for the UF110 includes 2 electropolished stainless steel grid shelves; the cabinet is designed to accommodate up to 5 shelves. If you regularly use all the levels, you order additional grid shelves or perforated sheets along with the unit. 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 wall bracket for space-saving installation. If you wish to run unattended cycles with redundant temperature monitoring, opt for the Memmert UF110plus universal oven. A USB-to-Ethernet adapter and AtmoCONTROL software licences are suitable for continuous data logging. For pharmaceutical or standards-governed applications, we arrange calibration, IQ/OQ/PQ and maintenance services, including DAkkS calibration on request.
