WTW SenTix 41 analogue pH electrode, integrated temperature sensor, 103635
The WTW SenTix 41 analogue pH electrode is a tried-and-tested electrochemical system solution for reliable, low-maintenance pH measurement in routine laboratory applications, educational institutions and field measurements. Designed for use with classic analogue pH meters from the WTW inoLab and Profiline series, this high-quality electrode offers precise signal transmission and extremely simple handling. For daily monitoring measurements in aqueous media, wastewater samples or environmental investigations, the focus is on straightforward, rapid deployment – which this robust combination probe guarantees whilst being gentle on materials and ensuring process reliability. Traditional analogue technology and integrated temperature compensation The mechatronic system architecture of the SenTix 41 is based on reliable, analogue signal transmission. The measured potential is transmitted via a shielded fixed cable directly to the analogue input stage of the pH meter. A key functional feature is the NTC 30 kOhm temperature sensor integrated into the sensor head. This sensor measures the sample temperature simultaneously with the pH value, enabling the connected meter to perform automatic temperature compensation in real time. This reliably eliminates thermodynamically induced measurement errors caused by fluctuating ambient temperatures, without the need to immerse a separate temperature sensor in the sample. Low-maintenance gel electrolyte and mechanical breakage protection The material design is consistently optimised for durability and minimal maintenance in everyday laboratory use. The electrode is fitted with a chemically resistant and extremely break-resistant POM plastic shaft. This shaft encloses the sensitive glass membrane like a mechanical protective cage and prevents damage in the event of falls or contact with vessel walls. A maintenance-free gel electrolyte, combined with a tried-and-tested fibre diaphragm, serves as the reference system. This sealed system permanently eliminates the need for the tedious refilling of liquid KCl solution and significantly reduces the risk of diaphragm blockages in multi-user operations. Universal connectivity and ergonomic laboratory use To ensure seamless integration into equipment, the SenTix 41 features a permanently attached 1-metre cable terminated in tried-and-tested standard connectors. The pH channel is connected via a standard DIN plug, whilst the integrated temperature sensor is connected via a 4 mm banana plug. This standardised plug combination guarantees universal compatibility with a wide range of analogue measuring stations on the market. The flexible cable ensures optimal ergonomic movement and allows fatigue-free working when carrying out sequential measurements on larger sample series directly at the workstation.

Individual requirements & accessories To ensure consistently high measurement accuracy of the WTW SenTix 41, regular recalibration of the measuring station is essential. For this purpose, our range includes certified WTW technical buffer solutions in practical dosing bottles (pH 4.01, pH 7.00 and pH 10.01). For the proper care and storage of the pH-sensitive glass membrane during measurement breaks, we strongly recommend the use of the original 3 mol/l KCl storage solution. Should the electrode ever become contaminated with stubborn sample residues during the rigours of everyday laboratory work, we offer special cleaning concentrates for gentle regeneration.

Bandelin SONOREX SUPER RK 31 Ultrasonic Bath, 0.9 L, 35 kHz, 329
Sensor tips, small cannulas, jewellery or individual cuvettes do not require a large bath for ultrasonic cleaning; rather, they need a bath that delivers uniform cavitation to every corner of the tank. With a total capacity of 0.9 l, the Bandelin SONOREX SUPER RK 31 is the smallest model in the SUPER RK series and is designed specifically for these small-item cleaning tasks in laboratories, medical practices and workshops.Small tank, noticeable cavitationAt an operating frequency of 35 kHz, the RK 31 generates a peak power of 160 watts at a rated power of 40 watts, distributed across a single transducer system. This is sufficient for the small tank volume of 0.9 l (working capacity 0.6 l); larger SUPER RK models, such as the RK 514 BH, on the other hand, operate with four transducers covering a significantly larger area. The automatic SweepTec function continuously adjusts the frequency slightly, thereby preventing standing waves in the ultrasonic field; as a result, the cleaning effect remains uniform even in small volumes.Thin stainless steel bath for the laboratory benchThe ultrasonic bath is made of 1.4301 stainless steel with a thickness of 0.8 millimetres; the housing is made from the same material. The internal dimensions of 190 x 85 x 60 mm and the compact external dimensions of 205 x 100 x 180 mm ensure that the unit, with a net weight of 2.2 kg, can still be accommodated even on already occupied work surfaces. The RK 31 is operated via a robust rotary handle; the timer ranges from 1 to 15 minutes in 5 per cent increments, and continuous operation is also available.No drain, no heating, but simpleThe data sheet explicitly states that this model has no drain; a ball valve is not provided for this size. With a capacity of 0.9 l, the basin can be emptied directly over the edge after the cleaning cycle; an additional connection would be rather cumbersome in this case. Similarly, the RK 31 does not feature a heating element. Anyone requiring heating for cleaning in the same size will find the RK 100 H, the next larger, heated model in the same series.Selection guide for the SUPER RK seriesThe SUPER RK series from Bandelin covers a wide range: from the RK 31 with a 0.9-litre capacity to the RK 1050 with a total capacity of 58 l. If you are only cleaning individual small parts, sensor tips or cuvettes, the RK 31 is the right choice. If the batch size increases to include several instruments or small glass vessels, it is worth considering the RK 100 H (3.0 l, heated) or the RK 103 H (4.0 l, heated and with a drain). For entire sieves or beakers, the larger models from the RK 510 (9.7 l) upwards are the more suitable choice.SUPER RK, DIGITEC DT and smart ST comparedIn addition to the SUPER RK series with classic rotary knob control, Bandelin offers the DIGITEC DT series with push-button control, an LED display and DEGAS degassing, as well as the smart ST series with a touchscreen, finely adjustable power control and programme memory. Those who only clean occasionally and value straightforward, robust operation would be well advised to choose a SUPER RK model such as the RK 31. LT Laborhandel also stocks Elma Elmasonic ultrasonic baths, an alternative for laboratories already equipped with this brand.Use and maintenanceThe working capacity of 0.6 l is deliberately set below the total capacity of 0.9 l, as space must be left for the items being cleaned when filling the bath; otherwise, the liquid will spill over the rim. As for the cleaning solution itself, Bandelin offers its own TICKOPUR range of concentrates; for the SONOREX PR series of pipette cleaners, this is included in the set, whilst a suitable concentrate for the RK 31 must be purchased separately. Freshly prepared cleaning fluid contains dissolved air, which initially dampens cavitation; a short pre-run in continuous operation before the actual cleaning process dispels it. The stainless-steel basin is compatible with most aqueous cleaning agents; however, abrasive sponges or chlorine-based agents should still be avoided. At the end of the working day, it is best to empty and dry the basin.Typical applicationsCleaning of small sensor tips, cannulas and needlesPrecision cleaning of jewellery and small metal partsPre-cleaning of precision mechanical components and watch movementsCleaning individual cuvettes or small sample vessels in the laboratoryFrequently asked questionsIs the SONOREX SUPER RK 31 heated? No, the RK 31 is the unheated version of this model. A heated variant with a similar volume is the RK 100 H.Does the unit have a drain? No, the technical data sheet does not specify a ball valve for the RK 31; with a capacity of 0.9 l, the bath is emptied directly.Is the RK 31 a medical device? Yes, it is classified as a Class I medical device in accordance with Regulation (EU) 2017/745 and is also CE-compliant with the Low Voltage, EMC and RoHS Directives.Are the basket and lid included in the scope of delivery?

Kern OZL 465 Stereo Zoom Microscope, 7x-45x Zoom, LED Reflected and Transmitted Light
Whether you’re checking a printed circuit board for soldering faults or preparing an insect for a biology lesson, you need an image with depth of field and the ability to switch quickly between an overview and close-up detail. The Kern OZL 465 stereo zoom microscope covers a zoom range of 0.7x to 4.5x; with the supplied 10x eyepieces, this gives a total magnification of 7x to 45x. The binocular head sits on a column stand, is tilted at 45 degrees and can be rotated through 360 degrees. LED lighting illuminates the specimen either from above or from below, with separate dimming controls. Kern positions this model as an all-rounder for schools, training centres, testing facilities and laboratories. Zoom range and field of view The zoom lens covers a range from 0.7x to 4.5x, a ratio of 6.4 to 1. When used with the HWF 10x eyepieces, this results in the stated total magnification of 7x to 45x. At the lower end of the zoom range, the field of view is 28.6 mm; at the upper end, it is 4.4 mm. This allows an entire circuit board to fit within the field of view, or a single solder joint to be viewed in close-up. The working distance of 105 mm leaves enough space for tweezers or a soldering iron beneath the optics, whilst the stage accommodates samples up to 140 mm in height. Head and stand adjusted to the user The dioptre adjustment operates on both sides from minus 5 to plus 5, whilst the interpupillary distance can be set between 55 and 75 mm. High-eye-point eyepieces ensure the distance between the eyes and the lens is sufficient for spectacle wearers. The microscope head is detachable; the head mount has a diameter of 76 mm and therefore also fits other modular Kern stands. Focusing is achieved via a coarse focus knob; the OZL 465 does not have a separate fine focus knob. LED illumination for reflected and transmitted light Incident and transmitted light can be dimmed separately, each with 3-watt LED output. Incident light illuminates opaque specimens such as printed circuit boards, minerals or insects from above, whilst transmitted light illuminates thin specimens and microscope slides from below. The contrast mode is brightfield. The presence of two independently controllable light sources in a single unit distinguishes the OZL 465 from simpler stereo microscopes with only one direction of illumination. Digitisation: optical in the basic model, expandable via accessories The basic model of the OZL 465 does not have a built-in camera sensor; it is a purely optical microscope. Users who wish to display or document the specimen on a screen can retrofit the microscope with an eyepiece camera. For users who require a digital image from the outset, Kern offers the OZL 462, a dedicated microscope head with a digital output. This is a standalone product with its own item number and is not part of this offer. Storage and warranty The housing can withstand storage temperatures ranging from minus 5 to 40 degrees Celsius, which is relevant for transport in winter or for temporary storage in an unheated adjoining room. Kern provides a 36-month warranty on the device and confirms, in accordance with REACH classification, that it contains no prohibited substances. Typical applications Kern cites a wide range of applications for the OZL-46 series, from reproductive medicine to quality control: In-vitro fertilisation Parasite detection Zoology and botany Tissue preparation and sections Quality control Specimens with a three-dimensional appearance, such as insects, seeds, printed circuit boards or components In educational settings, the microscope displays specimens from biology lessons in three dimensions rather than as flat images. In electronics manufacturing, quality assurance uses it to check solder joints and assembled printed circuit boards for completeness, without having to set up a digital system for every production run. Frequently asked questions about the OZL 465 Can a camera be fitted at a later date? Not as a retrofit directly onto the OZL 465, but an eyepiece camera can be added as an accessory. For a unit with a factory-fitted digital output, the separate OZL 462 head is the right choice. How tall can the sample be? The stage accommodates samples up to 140 mm in height. Is the microscope suitable for people who wear spectacles? Yes, the eyepieces are designed with a high eye point, and the dioptre adjustment ranges from minus 5 to plus 5 on both sides. How heavy is the microscope? The net weight is 4.6 kg, and the dimensions are 300 x 240 x 420 mm. Is transmitted light possible for thin specimens? Yes, transmitted light can be dimmed independently of the incident light; both light sources are LED-based. What type of plug is supplied? The mains adaptor comes with a EURO plug; other versions for the UK, US or Switzerland are available as options according to the data sheet.

KNF LABOPORT N 96 mini diaphragm vacuum pump, chemical-resistant, speed-controlled, 7 l/min, 322806
Compact performance for the laboratory workstation: KNF LABOPORT ® N 96 The KNF LABOPORT ® N 96 redefines what a compact laboratory pump is capable of. With MPN 322806, you get a highly flexible system that has been specially developed for applications where space-saving design, chemical resistance and precise control are required. Despite its very small footprint, this mini diaphragm vacuum pump delivers impressive performance and is ideal for filtration, solid-phase extraction (SPE), the removal of liquid supernatants or as a fore-vacuum pump for turbomolecular pumps. Chemical resistance meets maintenance-free operation A key advantage of the N 96 is its choice of materials. The pump head is made of robust PPS (polyphenylene sulphide), the diaphragm is PTFE-coated and the valves are made of FKM. This combination makes the pump extremely resistant to aggressive gases and vapours. Unlike oil-lubricated rotary vane pumps, the diaphragm principle of the N 96 operates 100 per cent oil-free. For you, this means: no contamination of your samples by oil vapours, no disposal of waste oil and completely maintenance-free operation in day-to-day laboratory work. You can transfer, evacuate and compress samples accurately and cleanly. Integrated speed control for gentle processes The LABOPORT ® N 96 is not simply ‘On’ or ‘Off’. It features integrated speed control, which is operated intuitively via a rotary knob on the top. This allows you to adjust the flow rate continuously to suit your process – from gentle suction right through to full power. The visual status indicator is particularly innovative: the colour of the LED lighting on the rotary knobs changes depending on the operating status (e.g. standby, operation), so you can see immediately – even from a distance – what the pump is currently doing. Quiet, low-vibration and space-saving In modern laboratories, space is at a premium and noise is a nuisance. The N 96 scores highly in both respects: with its extremely compact design, it fits into any nook or directly into the fume cupboard without blocking valuable worktop space. Thanks to its advanced diaphragm technology and brushless DC motor, it also operates very quietly and with minimal vibration. This is easier on the user’s nerves and allows for concentrated work right next to the unit. Versatility in application and pressure Although primarily known as a vacuum pump (ultimate vacuum < 130 mbar abs.), the N 96 can also be used as a compressor, delivering a working overpressure of up to 2.5 bar. The flow rate of up to 7 litres per minute (at atmospheric pressure) ensures rapid results during filtration. The plug-in power supply with wide-range input allows for use worldwide. Detailed technical specifications Flow rate (max.): 7 l/min (0.42 m³/h) at atmospheric pressure Final vacuum: < 130 mbar (abs.) Operating pressure: 2.5 bar Pump head material: PPS (polyphenylene sulphide) Diaphragm material: PTFE-coated Valve material: FKM Hose connection: For hoses with an ID of 6 mm Permissible fluid and ambient temperature: +5 °C to +40 °C Voltage: 100–240 V, 50/60 Hz (wide-range power supply) Protection rating: IP 40 Dimensions (W x H x D): 75 x 119 x 156 mm Weight: 1.3 kg Special features: Speed-controllable, status LED, chemical-resistant Contents 1 x KNF LABOPORT ® N 96 diaphragm vacuum pump 1 x mains adaptor (multi-plug) Operating instructions Custom requirements & accessories Do you need suitable vacuum hoses, fine-adjustment valves or suction bottles for your filtration setup?

IKA T 18 mini digital Solution Disperser Set, brushless motor including tool and stand, 0010015137
Not every laboratory workstation has room for a large drive, and not every sample requires 500 watts of power. The IKA T 18 mini digital Solution (0010015137) is designed precisely for these situations: a compact, brushless disperser set with an attachment and stand that can be accommodated even in small spaces and is designed for samples with lower viscosity. Compact brushless drive With external dimensions of 66 x 186 x 100 millimetres and a weight of 1.8 kilograms, the drive unit is significantly smaller than the classic T 18 digital. The brushless DC motor delivers 210 watts of input power and 160 watts of output power, and is designed for a maximum viscosity of 2,000 mPas. As with the larger series, the speed range extends from 3,000 to 25,000 revolutions per minute, albeit with a slightly higher tolerance of 3 per cent. Digital display, timer and USB-C The LED display shows the set speed, whilst an integrated timer with its own LED display manages the process time, meaning that runs do not need to be stopped manually. The device can be connected to a documentation system via the USB-C interface. In standby mode, power consumption is just 3 watts, whilst the maximum power consumption of the unit is 250 watts. Power is supplied internally via 48 volts DC at a current draw of 4,500 milliamps; the power supply unit itself covers the range from 100 to 240 volts and can therefore be used worldwide without the need for a separate voltage converter. Designed for smaller volumes and lower viscosity According to the manufacturer, the T 18 mini digital Solution is suitable for simple applications involving the homogenisation of low-viscosity samples. As with the larger model, the processable volume ranges from 0.001 to 1.5 litres; however, the maximum viscosity of 2,000 mPas is lower than that of the T 18 digital, which is 5,000 mPas. For routine samples in life sciences laboratories, training centres or smaller-scale quality control procedures that do not involve particularly viscous or high-volume batches, the performance is generally more than adequate. What the compact design means in everyday use With a footprint that is significantly smaller than that of the classic T 18 digital, the T 18 mini digital Solution can be accommodated even where several workstations are positioned close together, such as in practical training rooms or at smaller fume cupboard workstations. The lower weight of 1.8 kilograms also makes manual operation more comfortable over longer periods when a stand is not used. Those who regularly switch between several workstations also benefit from the fact that the compact unit is easier to transport than the larger series. Typical applications Homogenisation of low-viscosity samples (according to the manufacturer) Smaller batches in life sciences and teaching laboratories Workstations with limited floor space Processes with documented time control via the integrated timer Brief overview within the T-18 range For those requiring higher viscosity or greater motor power, the larger T 18 digital Solution offers the ideal set with a power consumption of 500 watts instead of 210 watts. LT Laborhandel supplies the drive unit on its own as the T 18 digital ULTRA-TURRAX; the dispersing tool included in the set is also available separately as the S 18 N - 19 G dispersing tool. Technical details Motor power consumption210 W Motor output160 W Processing volume (H₂O)0.001 to 1.5 l Max. viscosity2,000 mPas Speed range3,000 to 25,000 rpm, continuously variable Speed deviation3 % Speed displayLED Motor typeBrushless (direct current) Noise level without tools75 dB(A) Boom diameter13 mm Arm length160 mm Process typeBatch TimerYes, LED display Permissible duty cycle100 % Permissible ambient temperature range5 to 40 °C Permissible relative humidity80 % USB interfaceUSB-C Maximum power consumption250 W Standby power consumption3 W DC voltage48 V= Current consumption4,500 mA Dimensions (W x H x D)66 x 186 x 100 mm (drive unit) Weight1.8 kg (drive unit, excluding stand and tools) Power rating100 to 240 V, 50/60 Hz, 210 W (max. 250 W) Protection classIP 30 (DIN EN 60529) Contents 1 x IKA T 18 mini digital ULTRA-TURRAX (drive unit) 1 x S 18 N - 19 G dispersing tool 1 x R 1826 plate stand 1 x R 182 cross-sleeve Differences from the neighbouring series If you only require the drive unit without the set, it is available as the T 18 mini digital ULTRA-TURRAX. An overview of all dispersing units at LT Laborhandel can be found in the ‘Dispersing Units’ category; suitable tools are listed under ‘Dispersing Tools’. Application, installation and maintenance With an IP 30 protection rating, the drive unit is slightly better protected against the ingress of foreign objects than the classic T 18 digital with IP 20; however, it is still not designed to withstand splashing water. Operation is permitted at an ambient temperature of 5 to 40 degrees Celsius and a relative humidity of up to 80 per cent. The tool’s supplied PTFE bearing must not run dry; the medium provides both lubrication and cooling. The integrated timer reduces the effort required for manual time control in recurring processes, but does not replace the need to monitor the batch. At the end of its service life, as an electrical appliance, the drive must not be disposed of with household waste, but must be placed in the separate collection for waste electrical and electronic equipment. When the mini drive is a worthwhile investment If the viscosity of the samples is up to a maximum of 2,000 mPas and the focus is on a compact design, a timer and documentation via USB-C, the T 18 mini digital Solution reliably meets these requirements. If, on the other hand, thicker media up to 5,000 mPas are regularly processed, or if the higher power consumption of 500 watts is required, the larger T 18 digital Solution is the more suitable choice. Both sets share the same standard tool, the S 18 N – 19 G, so switching between the two sizes does not necessarily change the choice of tool. For laboratories that need to meet both requirements simultaneously – for example, a sensitive batch with low viscosity followed by a more viscous sample – it may also be worthwhile to purchase both sizes for different workstations. Individual requirements & procurement service Those who also work with disposable dispersing tools will find the S 18/25-ET50 disposable tube from LT Laborhandel to be a practical cleaning aid. Do you also require an additional stand for a second workstation or assistance with the USB connection to your documentation system? Through our procurement service, LT Laborhandel supports you with procurement and configuration. Frequently Asked Questions For which samples is the T 18 mini digital Solution suitable?According to the manufacturer, it is suitable for simple applications involving the homogenisation of low-viscosity samples, up to a maximum of 2,000 mPas. How does it differ from the larger T 18 digital Solution?The mini drive is brushless with a power consumption of 210 watts instead of 500 watts; it is more compact and designed for a lower maximum viscosity, but features a timer and a USB-C interface. Is a stand included in the scope of delivery?Yes, the set includes an R 1826 plate stand with an R 182 cross-sleeve. What is the USB-C interface used for?The USB-C port allows the device to be connected to a documentation system to record process data. What is the drive’s protection rating?IP 30 in accordance with DIN EN 60529, which protects against the ingress of foreign objects larger than 2.5 millimetres, but not against splashing water. Can I operate the drive worldwide without a voltage converter?Yes, the mains adaptor covers a range of 100 to 240 volts at 50/60 hertz.
Heidolph Hei-PLATE Mix 20l Magnetic Stirrer, up to 20 L, without Heating, 506-54100-00
If a batch requires more volume than a standard hotplate can accommodate, but at the same time does not require a heat source directly beneath the vessel, the Hei-PLATE Mix 20 l provides exactly this combination: stirring of up to 20 l without any heating function; according to the manufacturer, even the heat from the motor is not transferred to the work surface. The chassis is identical in construction to the Hei-PLATE Mix’n’Heat Core, but without the heating module, and covers a speed range from 100 to 1,400 revolutions per minute.No heat input for heat-sensitive substancesFor substances that are sensitive to heat, any additional source of temperature poses a risk, even the waste heat from a motor. The Hei-PLATE Mix 20 l is therefore deliberately designed without a heating function, ensuring that the base remains cool. A soft-start function gently brings the speed up to the set value, ensuring that the sample does not splash at start-up and the stirring rod does not veer off course.Large Kera-Disk platform for 20 lThe 145-millimetre-diameter Kera-Disk platform, made of aluminium with a ceramic coating, is chemical-resistant and scratch-resistant, and can support samples weighing up to 25 kilograms. With a power consumption of just 25 watts in normal operation, energy usage remains low for a unit with this stirring capacity; in standby mode, it drops to 1.7 watts. The external dimensions of 168 x 101 x 299 millimetres are consistent with the rest of the Hei-PLATE range, meaning the unit can be integrated into existing workstations without any modifications.Typical applicationsStirring of large-volume batches up to 20 l without heat inputProcessing of heat-labile active ingredients and dyesPreparation of larger volumes of buffers and reagents in routine laboratory workApplications where even minimal motor heat would interfere with the sampleSupplementing a Hei-PLATE workstation with a second, non-heated unitElectrical protection and environmental conditionsIP42 protection rating protects against foreign bodies larger than 1 mm and dripping water when tilted up to 15°; the sound pressure level is below 50 dB(A). The unit operates at 230 volts at 50 or 60 hertz in Europe and 115 volts in the USA, in each case via a connection with L, N and a protective earth conductor. The permissible operating range is from 5 to 31 degrees Celsius at up to 80 per cent relative humidity; above this, the permissible humidity decreases linearly down to 40 degrees Celsius.Selection guide: smaller volume or with heatingIf a 5-litre mixing volume is sufficient, the more compact Hei-Mix S is the smaller and simpler alternative. If a heating plate is required, the identically constructed chassis with a heating module, as the Hei-PLATE Mix’n’Heat Core, delivers temperatures up to 300 degrees Celsius; with additional digital Pt1000 control, it is available as the Hei-PLATE Mix’n’Heat Core+.Technical detailsDimensions (W x H x D)168 x 101 x 299 mmFootprint (Kera-Disk)Ø 145 mm, aluminium, ceramic-coatedWeightapprox. 3 kgMaximum permissible load25 kgDriveEC motor, counter-clockwise rotationSpeed range100 to 1,400 rpmProtection class (EN 60529)IP42Sound pressure level< 50 dB(A)Rated voltage230 V, 50/60 Hz (EU); 115 V, 50/60 Hz (US)Connection typeL+N+PEProtection classIOvervoltage categoryIIPollution degree2Power consumption25 W in normal operation, 1.7 W on standbyEMC classB, Group 1Operating temperature5 to 31 °C at up to 80 per cent relative humidity, 32 to 40 °C at up to 50 per cent relative humidity (linearly decreasing)Installation altitudeup to 2,000 m above sea levelScope of deliveryHei-PLATE Mix 20 l, order number 506-54100-00The silicone cover for the Hei-PLATE Mix 20 l is not included in the scope of delivery and must be ordered separately.Regulatory informationThis device is an electrical appliance within the meaning of the German Electrical and Electronic Equipment Act (ElektroG).

IKA T 25 digital LR disperser, for laboratory reactors, up to 2000 ml, 0020008820
Anyone wishing to prepare emulsions, suspensions or nanoparticle formulations not in an open beaker but in a closed, temperature-controlled laboratory reactor will need a drive that can be integrated into this system. The IKA T 25 digital LR disperser (0020008820) is designed precisely for this purpose: a dedicated drive unit for high-speed dispersion in laboratory reactors, with a volume range of 1 to 2,000 millilitres (based on water) and a speed range of 600 to 25,000 revolutions per minute. Unlike a benchtop disperser for open beakers, it is designed from the outset for mechanical integration into closed reactor systems and is not intended as a stand-alone, ready-to-use laboratory instrument. Powerful drive with infinitely variable speed control The 800-watt motor (500 watts output power) covers a continuously and electronically adjustable speed range from 600 to 25,000 revolutions per minute, displayed via a digital LED display with a deviation of just 1 per cent from the set target speed. In combination with the appropriate IKA dispersion tools, high shear forces are generated in the narrow shear gap between the rotor and stator, which break down particles and droplets and homogenise liquid phases – the classic operating principle of rotor-stator dispersers. The maximum permissible viscosity of the medium is 5,000 mPa·s, a guideline value that must be taken into account when selecting the dispersing tool and controlling the process. Designed for installation in laboratory reactor systems Unlike free-standing bench-top dispersers, the T 25 digital LR is designed as a drive unit only, which can be mechanically coupled with the special dispersing tools of the KD-LR series. These tools are designed for use in closed laboratory reactors such as the IKA LR 1000 and, thanks to high-quality shaft seals, enable operation under vacuum – which is useful for preventing aerosol and foam formation in media containing surfactants or for processing oxidation-sensitive batches under an inert atmosphere. Neither the dispersing tool nor the reactor itself is included with the T 25 digital LR; both must be purchased separately to suit the specific application. Electronic overload protection and digital display An integrated microprocessor maintains the set speed even when the resistance of the medium changes, for example if the viscosity of a batch increases during the reaction. If the stirring tool becomes suddenly blocked, for example by a jammed particle, an electronic overload protection system switches off the motor and displays an error code; this protects both the motor and the coupled dispersing tool. The unit is designed for continuous operation with a permissible duty cycle of 100 per cent. Compact design for mounting on a reactor stand Measuring 87 x 271 x 106 millimetres and weighing 2.5 kilograms, the T 25 digital LR can be mounted on a reactor stand to save space. The noise level without the dispersing tool fitted is 75 dB(A). The housing is rated to protection class IP 20 and approved for an ambient temperature of 5 to 40 degrees Celsius. It can be connected to either 220 to 240 volts or 100 to 120 volts at 50 or 60 hertz. Selecting the appropriate dispersing tool Which KD-LR tool is suitable in each individual case depends on the reactor volume, the desired immersion depth and the viscosity range of the medium. The tools in this series feature an extended design so that, even in larger reaction vessels, they reach right down to the bottom of the vessel and continue to disperse effectively there, rather than leaving dead volume unused. As the T 25 digital LR is designed as a drive for different reactor sizes and tool variants, the same drive can often continue to be used when process requirements change, whilst only the dispersing tool is replaced. Typical applications As a drive unit for laboratory reactors, the T 25 digital LR is used wherever dispersion processes must take place under controlled, closed conditions: Production of emulsions and creams under air-exclusion conditions in closed reactors Dispersion and homogenisation of suspensions with controlled temperature regulation Scale-up trials between open beaker stirring and pilot reactors Production of finely dispersed systems with limited sample volumes from 1 millilitre Process development in the pharmaceutical and fine chemicals industries with requirements for reproducibility Technical details Product typeDrive unit for dispersion tools in laboratory reactors Volume range (H₂O)1 to 2,000 ml Motor power (input / output)800 W / 500 W Speed range600 to 25,000 rpm, electronically continuously adjustable Speed deviation1 % Speed displayLED display Maximum permissible viscosity of the medium5,000 mPa·s Noise level (without dispersing tool)75 dB(A) Permissible duty cycle100 % (continuous operation) Motor protectionElectronic overload protection with error code display Dimensions (W x H x D)87 x 271 x 106 mm Arm length / Arm diameter160 mm / 13 mm Weight2.5 kg Protection class (to DIN EN 60529)IP 20 Permissible ambient temperature5 to 40 °C Power supply220 to 240 V or 100 to 120 V, 50/60 Hz Contents of delivery 1 x IKA T 25 digital LR drive unit 1 x mains lead for IT equipment 1 x operating instructions Not included are the required dispersing tool from the KD-LR series, the laboratory reactor itself, and a stand for mounting the drive unit. These components must be procured separately to suit the specific application. Customised requirements & procurement service As the T 25 digital LR is designed purely as a drive unit, you will also need a suitable dispersing tool from the KD-LR series and a stand solution to secure the drive in order to operate it on your laboratory reactor. Through our procurement service, we can assist you in selecting the appropriate dispersing tool for your specific application, as well as stand materials, spare parts and accessories for integration into existing reactor systems.

IKA C-MAG HS 7 control, magnetic stirrer with heating, ceramic hotplate, 0020002694
Thermodynamic infrared transmission and amorphous ceramic matrix The introduction of extremely high thermal energy into chemical reaction systems requires material architectures that are thermophysically resistant to massive temperature gradients. The IKA C-MAG HS 7 control utilises a monolithic base plate made of glass-hard, amorphous industrial ceramic (180 x 180 mm). This microstructured ceramic plate is not only characterised by absolute chemical inertness towards highly corrosive acids, halogens and bases, but also acts as an excellent infrared transmitter. With a massive heating capacity of 1,000 watts, the system generates surface temperatures of up to 500 °C. The thermal energy is not primarily transferred via pure heat conduction, but is coupled deep into the glass matrix of the reaction vessel with a high proportion of infrared radiation. This minimises thermodynamic latency and enables extremely rapid heating rates for high-boiling-point solvents or melt digestion. Electromagnetic kinematics and rheological trend metrology The physical mixing of structurally viscous fluids up to a macroscopic volume of 20 litres requires a constant, slip-free torque. The system generates a strong alternating electromagnetic field that continuously synchronises the stirring rod within the medium at speeds of 50 to 1,500 revolutions per minute. The electronic motor control compensates for rheological resistance in real time. A fundamental analytical function of this cybernetic model is the measurement of the relative torque trend. The system measures the electromagnetic phase shift induced by changes in the fluid’s viscosity during molecular polymerisation, cross-linking or crystallisation processes, and displays this vector change directly on the high-resolution LCD display. System cybernetics and hardened interface architecture To protect the electronic control unit in toxic or highly corrosive laboratory environments, the entire user interface is isolated behind a monolithic, chemically resistant sheet of real glass (hardened glass). Thermodynamic control within the medium is achieved via a PID cascade control system directly coupled to the supplied PT 1000 temperature sensor, thereby physically eliminating thermal overshoot. An independent, hardware-based safety circuit (continuously adjustable from 100 to 650 °C) and the IKA SmartTemp ® optical warning system guarantee absolute occupational health and safety by warning of latent infrared residual heat from the ceramic matrix, even after the primary power supply has been disconnected.

Customised requirements & accessories The C-MAG HS 7 control is a high-performance thermodynamic instrument that achieves its control precision solely through the exact positioning of the sensor system. To complete the PID control loop, the supplied PT-1000 probe must be positioned freely within the liquid phase. For this purpose, vertical locking using an IKA support rod (H 16 V) and cross-shaped sleeve (H 44) is essential. If the probe comes into contact with the hot vessel wall, this would distort the cybernetic control loop. For highly corrosive media that attack stainless steel, we recommend switching to the glass-sheathed PT 1000.70 probe. Please contact our procurement service at any time for the thermodynamically correct configuration.
Heidolph Hei-PLATE Sensor Basic Package Core+ Magnetic Stirrer Set, Ø145 mm, with Pt1000 Probe, 506-21150-00
A digital display on the hotplate and an external temperature probe in the vessel are, for many laboratories, the first step towards traceable temperature control. The Sensor Basic Core+ package combines the Hei-PLATE Mix’n’Heat Core+ digital magnetic stirrer, with a footprint of 145 millimetres, with an external Pt1000 temperature probe, whilst remaining a basic configuration without a stand or silicone cover.LCD display and two heating modesThe Hei-PLATE Mix’n’Heat Core+ included in the pack displays speed and temperature on an LCD screen; the dynamic control knobs respond to the speed of hand movement, slow for fine adjustment, fast for larger increments. There are two heating modes to choose from: FAST for rapid heating and PRECISE for control without overshoot. The included Pt1000 temperature probe (V4A, order number 509-67910-00) measures the temperature directly within the medium rather than just on the heating plate, with an accuracy of ±0.2 Kelvin plus the tolerance of the Pt1000 sensor and a resolution of 1 Kelvin. In conjunction with the probe, the magnetic stirrer covers a display and measurement range from 15 to 325 degrees Celsius.Why the temperature in the medium mattersWithout an external probe, a heating plate only controls the temperature of its own surface, not that of the liquid in the vessel. For buffers, solutions or reaction mixtures with a defined target temperature, this makes a difference, particularly when the volume or shape of the vessel changes. The Pt1000 probe is immersed in the medium and provides the control system with the actual value. This allows the set temperature to be reproduced independently of the vessel.Typical applicationsBuffer and solution preparations with a fixed target temperature in the vesselReaction mixtures where the temperature is to be monitored directly inside the flaskFirst steps towards documented temperature control without additional accessoriesUpgrading an existing Core+ magnetic stirrer with an external sensorSelection guide: Basic or AdvancedIf you wish to secure the sensor permanently and protect the work surface between uses, you’ll find the right equipment in the Core+ Sensor Advanced Package, which includes an additional mount and silicone cover. For reflux set-ups with a condenser, there are the dedicated Core+ and Core+ Mini reflux packages. If you do not require an LCD display and are happy with the simpler rotary knob operation, the Sensor Advanced Package Core offers the analogue alternative.Technical detailsDimensions (W x H x D)168 x 101 x 299 mmHeating plate footprintØ 145 mmWeightapprox. 3 kgMaximum permissible load25 kgDriveEC motor, counter-clockwise rotationSpeed range100 to 1,400 rpmheating power800 W at 230 V (EU), 600 W at 115 V (US)Heating temperature range20 to 300 °CHeating controlPIDDisplayLCD displayTemperature measurement accuracy±0.2 K plus Pt1000 toleranceTemperature measurement resolution1 KDisplay and measurement range with Pt100015 to 325 °CProtection class (EN 60529)IP42Sound pressure levelless than 50 dB(A)Rated voltage230 V, 50/60 Hz (EU), 115 V, 50/60 Hz (US)Power consumptionNormal operation 825 W (EU) / 625 W (US), standby 1.7 WScope of deliveryHei-PLATE Mix’n’Heat Core+ magnetic stirrer, 145 mm base area, order number 506-21100-00Pt1000 temperature sensor (V4A), order number 509-67910-00The mounting bracket and silicone cover are not included with this order number; they are part of the more comprehensive Sensor Advanced package.Regulatory informationThe devices in this package are electrical appliances within the meaning of the German Electrical and Electronic Equipment Act (ElektroG).

Kern OIV 345 Digital Video Microscope, 11.6-inch HD Display (PC-free), TOIV 345-B
Anyone who needs to examine a sample under a microscope whilst documenting it at the same time will be familiar with the bottleneck between the eyepiece and the computer. The Kern OIV 345 video microscope solves this by combining the optics, camera and an 11.6-inch HD display in a single unit. The image appears directly on the built-in screen, without the need for a computer, software installation or eyepiece. Display and image capture without a PC The 11.6-inch LCD display with tempered glass measures 275 x 170 x 12 mm, displays the camera image at 1920 x 1080 pixels (HD) and can be tilted between 0 and 45 degrees, ensuring a comfortable viewing angle at the workstation regardless of the operator’s height. The built-in 5-megapixel camera with a Sony CMOS sensor (1/2.8-inch) delivers a smooth live image at up to 60 frames per second, captured using a rolling shutter. The device is operated directly via the display using the supplied wireless USB mouse; a separate keyboard or computer is not required for day-to-day use. Recordings can be saved either to the supplied 32 GB USB stick or to a microSD card, again without the need for a computer. If you wish to display the image on a larger screen, for example, in a training session or when evaluating a sample as a team, you can connect the OIV 345 to an external monitor or projector via HDMI. Only for the advanced S-VIEWER software, with its additional measurement and evaluation functions, does a separate PC need to be connected via USB 2.0. For this, Kern recommends at least an Intel Core i3 or AMD Ryzen 5, 8 GB RAM, a 128 GB SSD, a graphics card in the class of an NVIDIA RTX 3060 or AMD Radeon RX 6600, and a Full HD screen of at least 20.5 inches. Click-stop zoom for reproducible magnification The optical zoom covers 0.7x to 4.5x directly at the sensor, giving a zoom ratio of 6.4:1. The display’s scaling factor of 22.8 results in a total magnification of 15.96x to 102.6x. The zoom wheel locks into defined click-stop positions, making it easier to recall a setting once it has been found for the next sample, for example when a series of similar components is inspected one after the other at the same magnification. A fixed 0.5x objective and the absence of an eyepiece keep the optical design simple: the system is axially aligned, meaning that the illumination and camera are positioned on the same axis as the sample, without any lateral offset. Illumination and working area The LED ring light is positioned as an incident light around the optics and can be dimmed continuously, from low background illumination to bright light for shiny or dark surfaces. It has a power output of 3 watts, and the contrast mode is bright-field. The working distance is 100 mm; samples up to 110 mm in height fit beneath the objective lens, such as smaller assemblies or workpieces that do not need to be dismantled first. The mechanical stand has a column height of 330 mm and supports the head, optics and display as a single unit. Power supply, dimensions and buffer cell Measuring 320 x 260 x 450 mm (W x D x H) and weighing 4.4 kg net, the unit stands securely on the laboratory bench without the need to allow for additional space for a separate monitor. The desktop power supply can be disconnected from the unit and covers an input range of 100 to 240 V AC at 50 or 60 Hz; the unit itself is supplied with 12 V at 2,000 mA, and the connection cable is 2.5 m long. This means the OIV 345 operates on virtually any standard mains supply, even outside Germany. The permissible storage temperature ranges from -5 to 40 °C. The housing also contains a very small lithium buffer cell with a lithium content of 2 mg and a capacity of 0.018 Wh. It has passed the UN38.3 transport test, which applies to the shipment of devices containing built-in lithium cells, including by air freight. Menu languages and S-VIEWER software The user interface is available in seven languages: German, English, French, Italian, Russian, Japanese and Chinese. The S-VIEWER software (Kern OXM 904) is also available for analysis on a PC. It covers image processing, video recording, documentation and measurement functions, in other words, precisely the steps that follow after simply viewing the results on the device, when a result is to be included in a test report or a quality assurance file. Anyone wishing to integrate the OIV 345 into an existing documentation system can export the images via a USB stick or MicroSD card and open them in the software on an office PC. Typical applications In quality control, a team can jointly inspect a solder joint or the edge of a component on the display, without having to take turns looking through the eyepiece. In electronics and semiconductor manufacturing, the axial optics assist in inspecting fine structures on circuit boards and components. In education and training, several people can view the same image simultaneously, which simplifies working with microscopes that have a single eyepiece. In mineralogy and tissue preparation, the instrument aids the visual assessment of samples; in materials testing, it facilitates the inspection of surfaces and fracture edges; and in parasite detection, it enables the examination of relevant specimens. Quality control Materials testing Electronics and semiconductor industry Education and training Research Mineralogy Tissue preparation Parasite detection Frequently Asked Questions Can the OIV 345 be used without a PC?

IKA C-MAG HS 7 magnetic stirrer package with heating, glass-ceramic base plate, including ETS-D5, 0010016454
The IKA C-MAG HS 7 Package magnetic stirrer with integrated heating represents a highly advanced, thermomechanical system solution for the precise mixing, heating and controlled temperature regulation of liquids in chemical, pharmaceutical and university laboratories. Designed as a high-performance complete system, this setup is validated for continuous stirring tasks up to a volume of 10 litres (based on water). For demanding thermal syntheses, the digestion of aggressive media or sample preparation, the precise interplay between high thermal energy input and a completely chemical-resistant work surface is the primary criterion for guaranteeing reliable experimental procedures that are gentle on the material and ensure process reliability. Highly chemically resistant glass-ceramic heating plate and powerful drive The process engineering foundation of the unit is the square heating plate (180 x 180 mm) made from seamless, high-quality glass-ceramic. This choice of material ensures unrivalled chemical resilience against extremely aggressive acids, alkalis and high-purity solvents. Furthermore, the non-porous glass surface enables gentle, residue-free cleaning. With a powerful heating output of 1,000 watts, the system achieves extremely short heat-up times to a plate temperature of 500 degrees Celsius. The integrated motor covers a wide speed range from 100 to 1,500 revolutions per minute and, thanks to strong magnetic coupling, reliably keeps the magnetic stir bar on track even with more viscous solutions. Precise temperature control via the integrated ETS-D5 contact thermometer The standout feature of the “Package” version is the IKA ETS-D5 electronic contact thermometer included as standard. The precision sensor is connected directly to the magnetic stirrer’s electronics via the integrated DIN 12878 socket. The sensor is immersed gently into the sample medium and reports the actual temperature in real time. This mechatronic control loop enables highly precise temperature control directly within the liquid, with outstanding control accuracy of ±0.5 K. Thermodynamic overshoots and unwanted overheating of sensitive samples are thus effectively eliminated during day-to-day field use. Ergonomic housing design and uncompromising health and safety The structural safety of the C-MAG HS 7 complies with strict GLP guidelines for long-term laboratory operation. The user interface features a raised control panel, which reliably protects the underlying electronics and displays from dripping or spilled liquids. An easy-to-read digital LED display accurately shows the set target temperature, whilst a digital error code mode immediately visualises any malfunctions. The integrated ‘Hot Top’ warning indicator ensures maximum occupational safety: a visual signal flashes for as long as the plate surface is heated to over 50 degrees Celsius – even after the unit has been switched off completely. A fixed safety cut-off at 550 degrees Celsius also prevents thermal damage to the heating mat.

WTW SenTix 81 analogue precision pH electrode, glass shaft, 103642
The WTW SenTix 81 analogue precision pH electrode represents a premium-class metrological system solution for high-precision and reliable pH measurement in demanding laboratory applications. Designed for use with classic analogue pH meters from the WTW inoLab and Profiline series, this high-quality glass electrode offers excellent signal transmission and the highest measurement accuracy. For complex tasks in chemical research, pharmaceutical quality control or university-level analysis, rapid and stable potential stabilisation is the primary criterion for ensuring reproducible measurement results in a process-reliable manner that minimises damage to the sample. Traditional analogue technology and integrated temperature compensation The mechatronic system architecture of the SenTix 81 is based on reliable, analogue signal transmission. The measured potential is transmitted via a high-quality, shielded fixed cable directly to the analogue input stage of the pH meter. A key functional feature is the 30 kOhm NTC temperature sensor integrated into the sensor head. This sensor measures the sample temperature simultaneously with the pH value, enabling the connected meter to perform automatic temperature compensation in real time. This reliably eliminates thermodynamically induced measurement errors caused by fluctuating ambient temperatures, without the need to immerse a separate temperature sensor in the sample. High-quality platinum diaphragm and refillable reference system The materials-science-based design is uncompromisingly optimised for maximum precision and fast response times. The electrode features a chemically highly resistant glass shaft and a cylindrical glass diaphragm. A tried-and-tested liquid electrolyte (3 mol/l KCl) serves as the reference system; this can be easily topped up or completely replaced via a sealable opening at the top of the glass shaft. A standout technological feature is the integrated platinum diaphragm. This specialised diaphragm ensures a continuous and uniform flow of electrolyte without the risk of blockages, even with challenging sample media such as emulsions, suspensions or slightly viscous solutions. Universal connectivity and ergonomic laboratory use To ensure seamless integration into laboratory set-ups, the SenTix 81 features a permanently attached, 1-metre-long cable terminated in tried-and-tested standard connectors. The pH channel is connected via a standard DIN plug, whilst the integrated temperature sensor is connected via a 4 mm banana plug.

IKA Rotary Evaporator RV 10 digital V Starter Solution, Complete Set with Vacuum Pump, Recirculating Chiller and Stand, 0010013947
Setting up a new laboratory or an additional distillation station usually means putting together drive, heating bath, vacuum pump, vacuum controller, recirculating chiller, stand and glassware individually and matching them to one another. The IKA RV 10 digital V Starter Solution rotary evaporator takes care of this step in advance: the RV 10 digital FLEX drive unit with motorised lift and integrated heating bath comes together with the VACSTAR lite vacuum pump, the VC 10 lite vacuum controller, the RC 2 lite recirculating chiller, a stand and the matching RV 10.1 glassware set in a single order. Anyone who wants to set up a functioning rotary evaporator station without searching separately for accessories will find the most complete configuration level of the RV 10 series here. The name Starter Solution is to be taken literally: everything needed for the first day of operation is already in the box. Selection guide: RV 3, RV 8 or RV 10, and which equipment level?Within the IKA rotary evaporator series, the Starter Solution marks a category of its own: instead of merely bundling drive, heating bath and glassware, it additionally includes vacuum pump, vacuum controller, recirculating chiller and stand. With the RV 10 digital V Starter Solution, the drive unit takes on the digital control level, with a motorised lift instead of a manual lift, but without the additional automatic vacuum control of the auto level. The following overview classifies the five common complete packages of the RV series. Model designationIKA RV 3 V | RV 3 V-C | RV 8 V | RV 10 digital V Starter Solution | RV 10 auto pro V-C Liftmanual | manual | manual (manual lift) | motor with safety-stop | motor with safety-stop Control leveleco | eco | heating bath with digital display | digital | auto, with integrated vacuum controller Condenser coatinguncoated | coated | uncoated | uncoated | coated Cooling surface1500 cm² on all five versions Speed range20 to 300 rpm | 20 to 300 rpm | 5 to 300 rpm | 5 to 280 rpm | 5 to 300 rpm Stroke150 mm | 150 mm | 120 mm | 140 mm | 140 mm Heating temperature rangeRoom temp. up to 99 °C | Room temp. up to 99 °C | Room temp. up to 180 °C | Room temp. up to 180 °C | Room temp. up to 180 °C Vacuum pump in the setno | no | no | yes, VACSTAR lite with VC 10 lite controller | yes, VACSTAR digital Recirculating chiller in the setno | no | no | yes, RC 2 lite | no Distinction within the RV familyIf you prefer automatic vacuum control and coated glassware, the IKA Rotary Evaporator RV 10 auto pro V-C offers the auto level of the same size, but there without recirculating chiller and stand in the set. Within the Starter Solution line itself there are two alternatives: the IKA RV 10 auto V Starter Solution with automatic instead of digital control and an otherwise comparable scope of delivery, and the smaller IKA Rotary Evaporator RV 8 V Starter Solution for laboratories with lower throughput or smaller flask sizes. All three Starter Solution packages follow the same basic idea: a complete station instead of individual components, so that the choice is guided primarily by the desired degree of automation and not by the question of which accessories are still missing. Typical applicationsThe Starter Solution package is exactly the right choice when a complete, immediately ready-to-use distillation station is needed without having to procure and match accessories separately: Setting up a new laboratory or a second distillation station without separate accessory procurement Teaching and training laboratories in which a complete, coherent set is to be taught Contract laboratories that need to set up an additional, operational evaporator station at short notice Solvent recovery and concentration with a closed cooling circuit via the supplied recirculating chiller Chemistry, pharmaceuticals, bio industry, research and development as well as production and quality assurance as typical operating environments of IKA rotary evaporators A matched system instead of individual componentsAnyone who procures vacuum pump, vacuum controller and recirculating chiller individually must first check whether delivery rate, ultimate pressure and cooling capacity actually suit the chosen drive unit. With the Starter Solution package, this comparison is no longer necessary: the VACSTAR lite with an ultimate pressure of 9 mbar and a delivery rate of up to 1.0 cubic metre per hour is already matched at the factory to the RV 10 digital FLEX drive unit together with the VC 10 lite vacuum controller, as is the RC 2 lite recirculating chiller to the cooling surface of the 1500 square centimetre vertical condenser. For laboratory managers this means above all one thing: less procurement effort and a lower risk that a single, wrongly dimensioned component limits the performance of the entire station. Use, installation and maintenanceThe drive unit is designed for ambient temperatures of 5 to 40 degrees Celsius and a relative humidity of up to 80 percent, protection class IP 20 according to DIN EN 60529. As the set consists of several independent devices, namely drive, vacuum pump, vacuum controller and recirculating chiller, a laboratory bench with sufficient space and a separate mains connection for the recirculating chiller is recommended, as its power consumption is separate from that of the drive unit, which is specified at up to 1400 watts at 220 to 240 volts. The VC 10.400 stand serves as the mechanical base for the glassware set and accessories and should be checked for a firm stance before first use. The RV 10.5005 hose set connects the vacuum pump, controller and cooling water circuit and should be replaced in good time if visibly worn, in order to maintain the vacuum tightness of the system. As other voltage variants are also available for the device, a brief check against the existing laboratory power supply is worthwhile before ordering.

This means that vacuum generation and cooling circuit, unlike with the individual RV 3 and RV 8 packages, are already fully included in the scope of delivery. 1 x RV 10 digital FLEX drive unit incl. heating bath, room temperature to 180 °C 1 x RV 10.1 vertical glassware set, uncoated (ident no. 0003655300) 1 x VC 10 lite vacuum controller (ident no. 0020111998) 1 x VACSTAR lite vacuum pump (ident no. 0020124926) 1 x VC 10.400 stand (ident no. 0035001735) 1 x RC 2 lite recirculating chiller (ident no. 0025006624) 1 x RV 10.5005 hose set (ident no. 0020000552) 1 x PC 1.3 cable Regulatory informationThe rotary evaporator and the additional devices included in the set (vacuum pump, vacuum controller, recirculating chiller) are electrical devices within the meaning of the WEEE Directive (ElektroG). The IKA WEEE registration number is DE 66784213. Take-back at the end of service life takes place within the framework of the statutory take-back obligations, and disposal with household waste is not permitted. Cost logic: what is in the set, what is still missing?Of the five packages compared here, the Starter Solution set is the only one that is immediately ready for operation without further procurement: vacuum pump, vacuum controller, recirculating chiller and stand are already included. Anyone who later wants to switch to coated glassware or the automatic vacuum control of the auto level can retrofit this via an additional glassware set or by changing the drive unit, without having to procure a new vacuum pump, controller or chiller. For laboratories with higher throughput, a second glassware set as an interchangeable set is the obvious next expansion step, while the rest of the peripherals can continue to be used unchanged. Especially for the initial equipment of a laboratory, this is a noticeable difference from separate procurement: instead of four to five individual orders, each with its own delivery time and its own compatibility check, a single order is enough to start distilling. Frequently asked questions Is everything really included for operation? Yes, drive, heating bath, VACSTAR lite vacuum pump, VC 10 lite vacuum controller, RC 2 lite recirculating chiller, stand and glassware set are part of the scope of delivery. Is the glassware coated? No, the uncoated RV 10.1 glassware set is included in the set. Coated glassware is standard on other RV 10 versions such as the RV 10 auto pro V-C. What ultimate pressure does the supplied vacuum pump reach? According to the data sheet, the VACSTAR lite reaches an ultimate pressure of 9 mbar at a delivery rate of up to 1.0 m³/h. How large is the heating bath? The integrated heating bath of the drive unit holds up to 3 litres and heats from room temperature up to 180 degrees Celsius. Can I switch to the auto control later? Yes, switching to the IKA RV 10 auto pro V-C rotary evaporator, which builds on the same drive and glassware standard, is a good option. Does the recirculating chiller need its own mains connection? Yes, the RC 2 lite recirculating chiller is an independent device with its own power consumption, independent of the drive unit. Are other voltage variants also available? Yes, according to the data sheet, in addition to 220 to 240 volts, 115 volts and several variants between 100 and 120 volts are also available. What does the addition Starter Solution stand for? Within the RV series, it identifies the packages that include a vacuum pump, vacuum controller, recirculating chiller and stand in addition to drive, heating bath and glassware. How many mains connections are needed at the workstation? As the drive unit, recirculating chiller and vacuum controller are separate devices, each with its own power consumption, the laboratory bench should have at least two to three independent, easily accessible sockets near the setup.

Bandelin SONOREX SUPER RK 156 BH Ultrasonic Bath with Heater, 9 L, 35 kHz, 646
Long pipettes, tubing, tools or bench lamps rarely fit into a square sink. The Bandelin SONOREX SUPER RK 156 BH, with internal dimensions of 500 x 140 x 150 mm, is deliberately designed to be narrow and long, thus providing a total capacity of 9.0 l for elongated items that cannot be accommodated in the more compact SUPER RK models.Narrow tank for elongated objectsWhilst most SUPER RK models have approximately square tanks, the RK 156 BH, measuring 500 mm in length and just 140 mm in width, is tailored to slender items: shorter laboratory glass rods, tools, hoses or several smaller instruments placed side by side. The working capacity is 6.0 l, and four oscillation systems ensure uniform ultrasonic agitation across the entire length of the tank.600-watt heater for thorough cleaningAt an operating frequency of 35 kHz, the RK 156 BH delivers 860 watts of peak power and 215 watts of rated power; the SweepTec function prevents standing waves across the elongated tank shape. The 600-watt heater covers a range of 30 to 80 degrees Celsius and is fitted with dry-run protection; the timer ranges from 1 to 15 minutes (± 5 per cent) or continuous operation, controlled via rotary knobs for time and temperature.Ball valve drain and robust constructionA G 1/4 ball valve on the right-hand side allows the tank to be drained in a controlled manner. The tank and housing are made of 1.4301 stainless steel with a thickness of 1.0 mm; the external dimensions of 530 x 165 x 300 mm and the net weight of 7.3 kg correspond to the narrow, elongated design. The housing is IP 32-rated, and the 2-metre power cable is permanently attached to the unit.When the BH design is suitableFor compact, roughly cube-shaped items to be cleaned, the standard SUPER RK models, such as the RK 510 H (9.7 l, but with a more square tank), are often the more practical choice. The RK 156 BH is worth considering where the length of the items to be cleaned is the main issue, such as with rods, longer tools or multiple objects that need to be placed side by side rather than on top of one another.Product range breakdown: SUPER RK, DIGITEC DT and smart STThe slim BH design is currently only available within the SUPER RK series with classic rotary knob controls. Those looking instead for digital button controls with an LED display will find them in the DIGITEC DT series, whilst the smart ST series features touchscreen controls with programme memory. LT Laborhandel also stocks Elma Elmasonic ultrasonic baths, although these are available in different tank sizes.Use and maintenanceThe working capacity of 6.0 l is less than the total capacity of 9.0 l, ensuring that no water spills over the rim when the items to be cleaned are placed inside. A concentrate from Bandelin’s TICKOPUR range is suitable as the cleaning agent. Freshly prepared liquid should be run briefly in continuous operation before the first cleaning cycle, so that dissolved air escapes and cavitation can take full effect. After use, the tank can be drained completely via the ball valve, leaving no residue, and then wiped dry.Typical applicationsCleaning of elongated tools, rods and hosesSimultaneous cleaning of several smaller instruments side by sidePre-cleaning of narrow laboratory glassware prior to further processingDegreasing of elongated metal parts in workshops and industryFrequently asked questionsWhy is the tank so narrow and long? The internal dimensions of 500 x 140 x 150 mm are specifically designed for elongated items that do not fit into more square-shaped tanks.Where is the drain? On the right, as a ball valve with a G 1/4 connection.Is the RK 156 BH heated? Yes, with a heating power of 600 watts and a temperature range of 30 to 80 degrees Celsius.How many agitation systems does the unit have? Four, distributed along the entire length of the tank to ensure uniform agitation.Technical detailsTotal capacity / Working capacity9.0 l / 6.0 lInternal tank dimensions (L x W x D)500 x 140 x 150 mmExternal dimensions (L x W x H)530 x 165 x 300 mmWeight (net)7.3 kgUltrasonic frequency35 kHzUltrasonic powerPeak power 860 W, rated power 215 W, 4 vibration systemsheating power600 W, temperature range 30 to 80 °C, dry-run protectionTimer1 to 15 minutes (± 5 per cent) or continuous operationOperationRotary knobFunctionsSweepTec, pulse functionTank materialStainless steel 1.4301, thickness 1.0 mmHousing materialStainless steel 1.4301drainBall valve G 1/4, right-hand sideMains connection230 V~ (± 10 %), 50/60 Hz, optionally 115 V~, 2 m fixed mains lead, protection class ICurrent consumption230 V 3.6 A / 115 V 7.1 AProtection ratingIP 32Medical device classClass I (Regulation (EU) 2017/745)ConformityLow Voltage Directive 2014/35/EU, EMC Directive 2014/30/EU, RoHS Directive 2011/65/EUPackaging dimensions655 x 265 x 370 mmScope of delivery1x Bandelin SONOREX SUPER RK 156 BH ultrasonic bath with heaterFixed mains lead (2 m)Instructions for useThe hanging basket and lid are not included in the scope of delivery and are available separately.Individual requirements and procurement serviceThe K 6 BL hanging basket, the D 156 lid or any other bath design from the SUPER RK series requires a bespoke procurement request.

Elma Elmasonic Easy 30H Ultrasonic Bath with Heating, 2.7 L, 37 kHz, 1117697
Not every cleaning task in the laboratory requires a digital display and programme memory. For pipette tips, small glassware or tools, a simple ultrasonic bath with fixed time settings is often sufficient. With a tank capacity of 2.7 l and a built-in heater, the Elma Elmasonic Easy 30H offers precisely this basic set-up for the laboratory bench, without controls that are not needed in day-to-day use anyway. The Easy series is designed for simple applications where a reliable, quick-to-use device is more important than programmability or multiple ultrasonic modes.Operation via a rotary knobInstead of a digital display and menus, the Easy 30H features an analogue rotary knob with ten fixed time settings ranging from 1 to 30 minutes, as well as continuous operation for up to 6 hours. LED indicators show the operating status; two ultrasonic modes, Eco and Dynamic, cover the vast majority of laboratory cleaning tasks. Those who only clean occasionally or use the unit at different workstations can use it without any training; a second glance at the manual is rarely necessary, and even new staff can be shown how to use it quickly.Compact bath for the laboratory benchThe tank has a capacity of 2.7 l; a working volume of 1.6 l is recommended, with internal dimensions of 220 x 120 x 95 mm. This is sufficient for pipette tips, small glassware, laboratory cutlery or tools, without the need to use a large amount of cleaning solution. A modular cleaning basket 30 (item no. 1108916) holds the items above the base of the tank; an insert lid 30/40 (item no. 1110262) or a stainless steel lid 30/40 (item no. 1111930) are available as accessories. For larger quantities of similar small parts, a suitable Hostalen tank is also available, which is used in size 30 for the Select and P models as well.Heating and performanceThe integrated heater ranges from 25 to 80 degrees Celsius with a heating power of 200 watts; the ultrasonic power is 80 watts effective with a peak power of 320 watts. The Easy 30H does not have a drain connection; to empty it, the tank is tilted or the water is scooped out into a separate container. For a unit of this size, this is generally not a disadvantage in everyday laboratory use, as the volume of water remains small. The IP20 protection rating also means that the housing itself is not designed to withstand splashing water; the unit must therefore be placed on a dry surface.Cleaning in day-to-day useA typical cleaning cycle begins by adding the cleaning solution directly into the tank; the appropriate time setting is then selected using the rotary knob, depending on the level of soiling, this ranges from a few minutes to continuous operation. The ‘Dynamic’ mode is suitable for more stubborn residues, whilst ‘Eco’ is designed for gentler routine cleaning with lower energy consumption. As no programmes are saved, the time setting is adjusted each time using the rotary knob; this does not involve any additional effort when there are only a few, clearly recurring cleaning steps.Accessories for different workpiecesDepending on the items to be cleaned, the Easy 30H can be used with a range of accessories. The modular cleaning basket 30 is suitable for loose small parts that should not rest directly on the bottom of the tank; the insert lid 30/40 seals the tank during operation without obstructing access to the control panel. The optional Hostalen tank serves as an inner liner and protects the stainless steel tank when using more aggressive cleaning agents or changing the bath frequently; this really pays off, particularly with daily use. For training workshops and test laboratories where different tools and small parts are cleaned one after the other, this allows flexible operation using the same basic unit, without the need to maintain a separate tank for each type of part.Choice within the Elma seriesWithin the Easy series, the models differ primarily in tank size; the smaller Easy 10H has a capacity of 0.9 l for very small parts. Those requiring additional programmable drains or a sweep function will find these in the Select series, whilst those wishing to carry out analytical precision cleaning using two frequencies, 37 and 80 kHz, will find what they need in the P series. LT Laborhandel also stocks Bandelin SONOREX ultrasonic baths for laboratories that already use this range of equipment.Typical applicationsCleaning of pipette tips and small glass partsCleaning of tools and instruments at training and workshop workstationsCleaning of small laboratory parts in routine operationsGetting started with ultrasonic cleaning without the need for programmingTechnical detailsTotal volume2.7 l (recommended working volume 1.6 l)Internal dimensions of tank (W x D x H)220 x 120 x 95 mmExternal dimensions (W x D x H)305 x 190 x 230 mmWeight3.3 kgUltrasonic frequency37 kHzUltrasonic power80 W effective, 320 W peakheating power200 WTemperature range25 to 80 degrees CelsiusOperating modesEco, DynamicTimerRotary knob, fixed settings: 1/2/3/4/5/10/15/20/25/30 minutes or continuous operation for up to 6 hoursTub materialStainless steeldrainNo drain connectionMains connectionIEC power connector 220 to 240 V~, 50/60 Hz, 2 m power cableProtection ratingIP20, protection class IScope of delivery1x Elma Elmasonic Easy 30H ultrasonic bathPlastic lidMains lead (2 m)User manualThe cleaning basket, insert lid and stainless steel lid are not included in the scope of delivery and are available separately.Individual requirements and procurement serviceFor the correct Cleaning Basket 30, insert lid or stainless steel lid, as well as the Hostalen basin, please contact the LT Laborhandel procurement service at lt-laborhandel.com/service.
WTW SenTix 61 glass pH electrode, refillable, DIN connector, 103640
Precision thanks to liquid electrolyte The WTW SenTix ® 61 is a high-quality standard pH electrode with a glass shaft, designed for demanding measurement tasks in the laboratory. Unlike gel-filled electrodes, this model utilises a liquid reference electrolyte (3 mol/l KCl, free from silver ions). This ensures a faster electrolyte flow and more stable potential formation, particularly with difficult samples. As the electrolyte is refillable, the user benefits from a significantly longer service life for the electrode compared with maintenance-free models. High-quality platinum diaphragm The built-in platinum wire diaphragm ensures a reliable connection between the sample and the reference system. It is characterised by a constant flow rate and is less prone to blockages than conventional ceramic diaphragms. The robust glass shaft is highly chemically resistant, easy to clean and ideally suited for use across a wide temperature range from 0 to 100 °C. Compatibility and connection The SenTix ® 61 (variant 103640) is fitted with a permanently attached 1-metre cable and a waterproof DIN plug. This connection standard ensures reliable signal transmission and is perfectly compatible with numerous WTW pH metres (e.g. the inoLab ® series) as well as other measuring instruments with a DIN socket. Please note that this model does not have an integrated temperature sensor; temperature measurement must be carried out separately if required. Technical details pH measurement range: 0 – 14 Temperature range: 0 – 100 °C Reference electrolyte: KCl 3 mol/l (liquid, refillable) Diaphragm: platinum Shaft material: Glass Shaft length / diameter: 120 mm / 12 mm Temperature sensor: No (NTC not integrated) Connection: DIN plug (waterproof) Cable length: 1 m (fixed) Diaphragm shape: Cylinder Diaphragm resistance (at 25°C): < 600 MOhm Contents of delivery WTW SenTix ® 61 pH electrode Fixed cable (1 m) with DIN plug Operating instructions Note: An initial supply of electrolyte is included; refill bottles must be ordered separately. Customised requirements & procurement service Do you need the correct electrolyte solution (KCl 3 mol/l), storage solution or a model with an integrated temperature sensor (e.g. SenTix 81)? We can advise you on optimal electrode maintenance. Please contact our procurement service for accessories and spare parts.
IKA S 18 N - 19 G Dispersing tool, coarse, PTFE bearings, 10 to 1,500 ml, L004640
The IKA S 18 N – 19 G (L004640) is the standard tool for coarse dispersion tasks on the IKA T 18 series drives, such as the T 18 digital ULTRA-TURRAX. The stainless steel tool covers a working range of 0.01 to 1.5 litres (10 to 1,500 millilitres, based on water) and is therefore the obvious choice for day-to-day sample preparation when rapid grinding and mixing are required. Toothed geometry for pre-grinding The letter G in the model designation stands for ‘coarse’. Unlike fine-grinding tools, the stator of this model features a coarsely serrated geometry with a gap width of 0.25 millimetres between the rotor and stator. This makes the S 18 N - 19 G the obvious choice for the pre-grinding of solid sample components, the mixing of pigments or fillers into coarse suspensions, and for viscous media that could clog finer tools. PTFE bearings for contact with aggressive media The rotor shaft is mounted in a PTFE bearing, as indicated by the letter ‘N’ in the model designation. PTFE is chemically almost inert, meaning the tool can be used with aggressive solvents, acids and alkalis without the bearing being affected. One important application note remains: PTFE bearings rely on the medium for lubrication and cooling; the tool must therefore not run dry, otherwise the resulting frictional heat will destroy the bearing. Hygiene and material quality Manufactured from electropolished AISI 316L stainless steel, the tool meets high hygiene standards. It is corrosion-resistant, durable and can be easily dismantled and sterilised for applications in the medical or microbiological fields, whether by chemical disinfection, dry heat or in an autoclave. This prevents cross-contamination between different sample batches. Typical applications According to the manufacturer, the S 18 N - 19 G is designed as a dispersing tool for the T 18 digital drive for volumes ranging from 10 to 1,500 millilitres. In practice, it is suitable for: Preliminary grinding of solid components in liquid samples Coarse suspensions containing pigments or fillers Viscous media that would be too viscous for finer tools Sample preparation with high requirements for chemical resistance Selection guide within the tool range In addition to the coarse version described here, LT Laborhandel stocks further tools for the T-18 drives with different gap geometries or made from different materials. The S 18 N - 10 G, with a narrower gap width, is suitable for finer end products; for single-use requirements and applications where no cleaning is required between samples, the plastic tools S 18 D - 10 G - KS and S 18 D - 14 G - KS are available.

Compatible drives The S 18 N - 19 G is designed for use with several drives in the T-18 range: the T 18 digital ULTRA-TURRAX, as well as the T 18 digital Solution and T 18 mini digital Solution complete sets, which already include this tool. According to the manufacturer’s compatibility information, it is also compatible with the brushless drives T 18 brushless digital ULTRA-TURRAX, T 18 brushless digital Solution and the compact T 18 mini digital ULTRA-TURRAX. Use, maintenance and disposal Before first use, the tool should be securely screwed onto the drive unit and checked to ensure it is firmly in place. During operation, the tool must remain fully submerged in the medium at all times; the immersion depth ranges from 35 to 170 millimetres, depending on the container. After use, the tool can be detached from the drive unit for cleaning and, depending on requirements, chemically disinfected, treated with dry heat or autoclaved. As an accessory to an electrical appliance, the end-of-life tool must not be disposed of with household waste, but must be disposed of properly together with the associated drive unit. Individual requirements & procurement service Do you require a tool for finer emulsions, a spare part or assistance in selecting the appropriate gap geometry for your sample? Through our procurement service, LT Laborhandel can assist you with procurement and compatibility enquiries. Frequently Asked Questions Which drives is the S 18 N - 19 G suitable for?It is suitable for the T-18 drive family, including the T 18 digital ULTRA-TURRAX and the T-18 brushless drives. What do the letters G and N in the name mean?G stands for the coarse-toothed stator geometry, and N for the PTFE bearing on the rotor shaft. Can I use the tool with solvents?Yes, the PTFE bearing is virtually chemically inert and suitable for aggressive solvents, acids and alkalis, provided the tool does not run dry. Is the tool autoclavable?Yes, according to the manufacturer, it can be sterilised using all standard methods, including autoclaving.
Bandelin SONOREX SUPER RK 1040 ultrasonic bath, 39.5 litres, 319
SONOREX SUPER RK 1040 ultrasonic bath for professional laboratory cleaning The SONOREX SUPER RK 1040 ultrasonic bath from Bandelin is designed for demanding use in laboratories, medical practices and industrial quality assurance. With a total capacity of 39.5 litres and a working capacity of 28.0 litres, the tank offers sufficient volume to clean even larger batches of laboratory glassware, instruments or small parts in a single cycle. Typical applications include the cleaning and sterilisation of instruments, the degassing of solvents prior to analytical processes, and the gentle cleaning of laboratory glassware, pipettes and other small parts where mechanical brushing is not an option. The ultrasonic bath is made of 1.4301 stainless steel with a wall thickness of 2.5 mm; the housing is also made of 1.4301 stainless steel. This choice of materials ensures high resistance to the cleaning agents and disinfectants commonly used in everyday laboratory work, as well as a long service life even under intensive continuous use. A fill-level mark makes it easier to fill the bath correctly, and the ball valve (G ¾) fitted on the side, with a 50 cm hose, allows the bath to be emptied easily and cleanly without having to tip the unit over. Consistent cleaning results thanks to SweepTec technology The SONOREX SUPER RK 1040 operates at an ultrasonic frequency of 35 kHz with a rated power of 380 W (peak power 1520 W). The fully automatic SweepTec function prevents standing waves in the ultrasonic field, thereby ensuring consistent, reproducible cleaning results across the entire tank surface – an important consideration when cleaning delicate or irregularly shaped items simultaneously. The cleaning duration can be conveniently adjusted via a rotary knob within a range of 1 to 15 minutes (± 5 per cent); alternatively, continuous operation is available. The unit is designed for operation at 230 V~ (±10 %), 50/60 Hz and is fitted with a permanently attached, 2-metre-long mains cable. The housing has an IP 32 protection rating.

IKA T 18 digital ULTRA-TURRAX disperser, tool-free drive unit, 500 W, 0003720000
Anyone who frequently homogenises samples in the laboratory will be familiar with the problem: a good drive alone is not enough; ultimately, it is the right tool that determines the final fineness and throughput. The IKA T 18 digital ULTRA-TURRAX (0003720000) is designed precisely with this in mind. It is supplied as a drive unit only, with a power consumption of 500 watts, which can be freely combined with various S-18 tools for coarse, fine or single-use applications. The LED display shows the set speed – between 3,000 and 25,000 revolutions per minute – at all times, which facilitates reproducible results across multiple test runs. Rotor-stator principle with high shear rates During dispersion, the tool draws the sample in axially and forces it out radially through the narrow slots between the rotor and stator. This briefly generates very high shear rates, which break down solid components and mix liquids into stable emulsions or suspensions. With an output power of 300 watts and a processable volume of 0.001 to 1.5 litres (based on water), the T 18 digital covers typical laboratory batches up to a maximum viscosity of 5,000 mPas. Stepless speed control with LED display The speed can be adjusted continuously between 3,000 and 25,000 rpm, with a deviation of just 1 per cent according to the data sheet. Unlike purely analogue controllers, the LED display shows the set value directly. Once process parameters have been determined, they can be noted down and reproduced exactly for subsequent experiments. With a permissible duty cycle of 100 per cent, prolonged continuous operation is also possible without the drive having to pause in between. The choice of tool determines the result The T 18 digital is deliberately supplied without a dispersing tool, as the most suitable tool depends heavily on the specific sample. The standard S 18 N – 19 G tool with PTFE bearings is suitable for coarse pre-shredding and tougher media, whilst the S 18 N – 10 G offers a narrower gap geometry for finer end products. Those who frequently work with varying samples that are potentially susceptible to contamination will find disposable plastic tools to be a practical alternative, as they rule out cross-contamination between batches from the outset. Typical areas of application As a standalone drive unit, the T 18 digital is particularly suitable for laboratories that already work with a variety of tools or switch specifically between several applications: Preparation of emulsions and suspensions in sample preparation Homogenisation of tissue samples in biology and life sciences research Mixing pigments and fillers into dispersions Routine tasks in quality assurance with varying tool configurations Setting up customised workstations through flexible combination with a stand and tool Selection guide for the T-18 range Drive unit only, complete set or just the tool? The four T-18 variants stocked by LT Laborhandel differ primarily in terms of what is included in the scope of delivery and, in the case of the mini-drive, in terms of motor power.

Differences from the neighbouring series If you also require a brushless motor with a timer, the IKA T 18 brushless series offers the next step up: the T 18 brushless digital ULTRA-TURRAX as a drive unit without an attachment, or the T 18 brushless digital Solution as a complete set. Both drive units operate with lower wear than the classic T 18 digital. An overview of all dispersers available from LT Laborhandel can be found in the ‘Dispersers’ category; suitable tools are listed under ‘Dispersing Tools’. Application, set-up and maintenance For short-term manual operation, the T 18 digital fits comfortably in the hand; for longer or reproducible processes, it can be securely mounted on a stand, such as the R 1826 plate stand. Operation is permitted at an ambient temperature of 5 to 40 degrees Celsius and a relative humidity of up to 80 per cent at 31 degrees Celsius, decreasing linearly to a maximum of 50 per cent at 40 degrees Celsius. The drive, with protection class IP 20, is not designed for use in damp rooms or outdoors. After each use, the tool used should be dismantled and, depending on the material, cleaned or sterilised before the next procedure begins. At the end of its service life, as an electrical appliance, the drive must not be disposed of with household waste but must be placed in the separate collection for waste electrical and electronic equipment. Individual requirements & procurement service In addition to the standard tools, LT Laborhandel supplies further accessories for the T 18 digital, such as stands, mounting elements or the Silentstream flow breaker to reduce air ingress during dispersion. Do you require a specific tool, a qualification document or assistance in selecting the right configuration? Through our procurement service, LT Laborhandel can assist you with procurement and configuration. Frequently Asked Questions Is a dispersing tool included in the scope of delivery?No, the T 18 digital is supplied exclusively as a drive unit. A suitable tool, such as the S 18 N - 19 G, must be purchased separately. Which tool is suitable for coarse pre-grinding?For coarse applications and tougher media, the S 18 N - 19 G with PTFE bearings is the standard choice; finer end products can be achieved with the S 18 N - 10 G. How accurately can the speed be reproduced?The LED display shows the set value within a range of 3,000 to 25,000 rpm with a deviation of around 1 per cent, which facilitates the exact repetition of test series. Is a stand included in the scope of delivery?No; for continuous operation, we recommend a separately available stand such as the R 1826 plate stand. What is the difference between the T 18 digital and the T 18 mini digital Solution?The T 18 mini digital Solution features a more compact, brushless drive with lower motor power and comes as a set including the tool and stand; the T 18 digital described here is the more powerful drive unit without accessories.
Bürkle foot-operated solvent pump with outlet hose and tap, 5603-3000
The Bürkle solvent pump, featuring foot operation, a discharge hose and a shut-off valve, represents a high-purity, occupational safety-optimised system solution for the contamination-free transfer and filling of organic solvents, acids, alkalis and flammable liquids from drums and large containers. In industrial production facilities, chemical laboratories and pharmaceutical filling plants, handling highly volatile or flammable media places the highest demands on explosion protection and ergonomics. Through the consistent use of chemically inert materials such as stainless steel and PTFE (Teflon), the purity of the filled media is fully preserved. For laboratory managers, health and safety officers and procurement staff in the B2B sector, this foot-operated pump offers the highest level of process reliability, as it enables precise, drip-free dosing whilst keeping the operator’s hands free to hold the target vessel. Ergonomic foot operation for maximum occupational safety The mechanical system architecture is characterised by convenient foot operation via a separate, robust foot bar. Activating the pump with the foot builds up a transient overpressure in the container, which delivers the liquid gently and evenly upwards through the riser tube. This contact-free operation offers a decisive advantage in terms of occupational safety: the operator has both hands free to position measuring cylinders, flasks or canisters precisely beneath the spout. This effectively minimises accidental spillage or dangerous splashes of corrosive chemicals during daily field use. Material inertness for high-purity media All functional components of the drum pump that come into contact with samples and media are manufactured from materials of the very highest quality. The robust immersion tube and the media-carrying valves are made of high-purity type 1.4301 (AISI 304) stainless steel, whilst all seals and the flexible outlet hose are made of chemically unrivalled PTFE. This material-science specification guarantees universal resistance to highly aggressive organic solvents such as acetone, ethanol, methanol or toluene. As the pump is designed to be completely free of lubricants or plastics containing plasticisers, high-purity sample quality is permanently guaranteed without any cross-contamination from the materials. Gas-tight seal and controlled drainage of residual quantities The Bürkle solvent pump is securely and airtightly fixed in the container’s bunghole via a highly stable drum coupling. This gas-tight system seal reliably prevents harmful solvent vapours from entering the ambient air and the breathing zone of laboratory staff during the pumping process. The flexible, 1.2-metre-long PTFE outlet hose is fitted with a precision stainless steel shut-off valve. This valve allows for absolutely precise, drip-free dispensing of even the smallest volumes. Thanks to the infinitely variable height-adjustable drum thread, the pump’s immersion depth can be perfectly adapted to the specific container geometry, ensuring excellent drainage of residual quantities. Technical details Pump characteristics & kinematics Pump type: Solvent pump / drum pump with manual foot operation Flow rate: approx. 20 litres per minute (depending on the viscosity of the medium) Operating mode: Foot-operated via a separate foot bar with pressure hose Dosing: Precise control via manual stainless steel shut-off valve Materials Science & Media Compatibility Materials in contact with the medium: Stainless steel 1.4301 (AISI 304) and PTFE (Teflon) Sealing materials: Pure, chemically inert PTFE Lubricants: Manufactured entirely free of lubricants and plasticisers Chemical resistance: Optimised for high-purity solvents, alcohols, flammable liquids and low-viscosity chemicals Design & Dimensions Immersion depth (immersion tube length): 950 mm (continuously height-adjustable) Immersion tube diameter: 18 mm Outlet type: Flexible PTFE outlet hose with stainless steel tap Outlet hose length: 1.2 metres Standard container connection: Suitable for steel drums with M64x4 internal thread (drum coupling included) Health and safety & approvals Explosion protection: Suitable for flammable media when used in conjunction with an anti-static earthing kit Emission control: Gas-tight system seal against hazardous solvent vapours Scope of supply 1 x Bürkle solvent pump, foot-operated base unit (MPN: 5603-3000) 1 x flexible PTFE outlet hose (length 1.2 metres) with stainless steel shut-off valve 1 x foot pedal bar including air connection hose 1 x drum coupling for M64x4 steel drum thread 1 x operating instructions Custom requirements & accessories When dispensing highly flammable and combustible solvents (such as petrol, toluene or isopropanol), friction can generate dangerous electrostatic charges. To ensure explosion protection in accordance with strict health and safety guidelines, the use of a suitable anti-static kit is essential. Our range includes the original Bürkle anti-static kit (earthing cable with brass clamps), which safely dissipates electrostatic energy to earth in a way that is gentle on materials and ensures process reliability. For use with plastic drums, sheet metal containers or other containers, we also offer a comprehensive range of threaded adaptors (e.g. for Mauser threads, Tri-Sure or 2-inch coarse threads). Please make use of our technical procurement service to ensure the safe configuration of your hazardous materials workstation.
IKA T 18 digital Solution Disperser Set, including tool and stand, 0009024700
For those who want to get started straight away, without having to assemble the drive, tool and stand individually first, the IKA T 18 digital Solution (0009024700) offers a fully coordinated complete package. The set combines the tried-and-tested T 18 digital drive with the standard S 18 N - 19 G dispersing tool and a sturdy plate stand complete with cross-sleeve, all ready for use straight out of the box. Everything included for an immediate start Instead of ordering four separate items and checking whether they fit together, the Solution version supplies all components in a single package: Drive: IKA T 18 digital ULTRA-TURRAX with 500-watt power consumption Dispersing tool: S 18 N - 19 G with PTFE bearings for coarse to medium-duty applications Mounting: R 1826 plate stand including R 182 cross-sleeve for a stable, low-vibration base Digital speed control with LED display The speed range extends from 3,000 to 25,000 revolutions per minute, is infinitely variable and has a deviation of around 1 per cent according to the data sheet. The LED display shows the set value directly, so that once process parameters have been determined, they can be noted down and repeated for subsequent trials. With an output power of 300 watts, the drive can process samples with a viscosity of up to 5,000 mPas. With a permissible duty cycle of 100 per cent, the drive can also be operated continuously for longer process stages without the need to schedule a cooling break between batches. Tool S 18 N - 19 G ready for use The supplied tool covers a working range of 10 to 1,500 millilitres and, with its coarsely toothed geometry, is suitable for the pre-shredding of solid components as well as for more viscous media. The rotor shaft is mounted in PTFE, which is resistant to most solvents, acids and alkalis. Details on the design and limit values of the tool can be found in the separate S 18 N – 19 G dispersing tool data sheet. Interchangeable tool for different samples Even though the set is already equipped with a suitable tool, the drive remains compatible with the entire S-18 tool range. A quick-release coupling allows for tool changes without the need for a tool kit, meaning that, if required, a finer tool for smaller end products or a single-use tool for contamination-sensitive batches can be fitted. For day-to-day use with varying sample types, this is a significant advantage over a permanently fitted tool: the set covers the basics but grows in line with the laboratory’s requirements. Typical areas of application As a complete package, the T 18 digital Solution is particularly suitable for new purchases and the setting up of additional workstations: Re-equipping laboratory workstations without existing dispersion accessories Preparation of emulsions and suspensions in sample preparation Homogenisation of samples in quality control and routine analysis Teaching and training laboratories where a ready-to-use kit is required Brief overview within the T-18 range In addition to this set, LT Laborhandel stocks the T 18 digital ULTRA-TURRAX drive (tool-free) for those who already own their own accessories, as well as the more compact T 18 mini digital Solution with a brushless drive and lower motor power for smaller work surfaces. Anyone wishing to reorder just the included tool separately can find it as the S 18 N - 19 G dispersing tool.

An overview of all dispersers available from LT Laborhandel can be found in the ‘Dispersers’ category. Application, installation and maintenance The supplied plate stand ensures a secure, low-vibration base even at high speeds and is particularly suitable for longer or unattended process stages. Operation is permitted at an ambient temperature of 5 to 40 degrees Celsius and a relative humidity of up to 80 per cent at 31 degrees Celsius, decreasing linearly to a maximum of 50 per cent at 40 degrees Celsius. The PTFE bearing of the supplied tool must not run dry; the medium serves both as lubrication and cooling. After use, the tool can be disconnected from the drive for cleaning or sterilisation, as can the stand, which can be detached again for the next configuration. At the end of its service life, the drive, as an electrical appliance, must not be disposed of with household waste but must be placed in the separate collection for waste electrical and electronic equipment. When the complete set is worthwhile For laboratories that do not yet own a T-18 drive, the set saves time on ordering and compatibility checks compared to purchasing the drive, tool and stand separately. On the other hand, those who already have a suitable stand or several tools and only require an additional drive may find it more cost-effective to opt for the separately available T 18 digital ULTRA-TURRAX without the set. For a second or third workstation with identical equipment, however, the complete set is once again the ideal choice, as it ensures that each station is equipped independently of the others. Individual requirements & procurement service For regulated environments where the introduction of equipment must be documented, LT Laborhandel also provides qualification documentation for the T 18 digital Solution, such as IQ/OQ documents, factory calibration certificates or general certificates in accordance with 2.2/3.1. Do you also require additional or alternative tools for abrasive or particularly viscous media, a second stand for an extra workstation, or assistance in selecting the right configuration? Through our procurement service, LT Laborhandel supports you with procurement and documentation. Frequently Asked Questions Is the T 18 digital Solution ready for immediate use?Yes, the drive, the S 18 N – 19 G dispersing tool and the plate stand are included in the set and are designed to work together. Which tool is included in the set?The S 18 N – 19 G with PTFE bearings, suitable for coarse pre-grinding and a working volume of 10 to 1,500 millilitres. How does the set differ from the T 18 digital drive sold separately?The T 18 digital ULTRA-TURRAX drive, available separately, is supplied without the tool or stand; the Solution Set already includes both components. Can I use a different tool instead of the one supplied?Yes, the drive is compatible with the entire S-18 range of tools, so finer or coarser variants can be retrofitted if required. Is the stand permanently attached to the drive?No, the drive, tool and stand can be detached from one another, for example for cleaning or for use at different workstations. Are qualification documents available for the set?Yes, LT Laborhandel can provide IQ/OQ documents, factory calibration certificates and general certificates in accordance with 2.2/3.1 for the T 18 digital Solution on request.
Bürkle Hand Pump for Solvents, V2A Stainless Steel, for Containers up to 60 L, 5603-1000
Anyone who scoops solvent from a 60-litre drum using a beaker or a jug risks splashes and direct skin contact with the liquid. The hand pump for solvents, on the other hand, operates on the principle of positive pressure: A pump ball forces air into the sealed drum; the resulting overpressure pushes the solvent out in a controlled manner through the fixed spout. This allows flammable solvents to be dispensed in measured quantities without having to tip the drum over or leave it open permanently.Operation without suctionUnlike a suction pump, the hand pump does not create a vacuum in the riser tube, but rather positive pressure inside the drum itself. The pump bulb is operated by hand; air flows through a tube into the drum, whilst the solvent rises separately to the spout. The shut-off valve at the end of the spout, made of stainless steel and PTFE, stops the flow immediately once the receiving container is full.For drums up to 60 l with a G2-inch threadThe pump fits containers with a G2-inch external thread and a capacity of up to approximately 60 l. The dip tube can be continuously adjusted to the actual depth of the drum; at full immersion depth, it extends up to 60 centimetres into the drum. With a flow rate of around 10 l per minute and a viscosity of up to 500 mPa·s, the pump is suitable for low- to medium-viscosity solvents. The 12-millimetre external diameter of the outlet fits standard funnels and canister openings, allowing the target container to be filled directly beneath the outlet elbow.Materials in contact with solventsAll parts in contact with the medium are made of 1.4301 (V2A) stainless steel and PTFE. Both materials are chemically resistant to organic solvents and aromatic compounds and can withstand regular cleaning after filling. Unlike a plastic pump, stainless steel does not swell when frequently exposed to more aggressive solvents and retains its fit, even after many filling cycles.Independent of mains power and compressed airThe hand pump requires neither a mains power connection nor a compressed air supply; it operates solely by means of the pump ball in the hand. This makes it ideal for workplaces where there is no compressed air network, such as in smaller workshops, for mobile operations or in storage areas away from the main infrastructure. Those who only open a drum occasionally can therefore manage without having to purchase a compressor.Safety when handling flammable liquidsBürkle expressly refers to the explosion protection guidelines for handling flammable, highly combustible liquids when using this pump: all parts must be earthed; in addition, the manufacturer recommends an anti-static kit. The product page does not specify a particular ATEX certification; the advice is intended as a recommendation for safe operation.If a different container or drive type is requiredFor tinplate canisters with bellows closures, the solvent pump for tinplate canisters is available as a hand pump of identical design, featuring a suitable adapter instead of a G2-inch thread. If both hands need to remain free, or if larger 220-litre drums are being used, the foot-operated solvent pump with spout is the more suitable choice. For small containers such as bottles or canisters up to 10 l with a GL45 thread, the Mini solvent pump is more suitable.Typical applicationsContamination-free dispensing of organic solvents and aromatic compounds from 60-litre drumsPrecise dispensing of flammable liquids in the laboratory, workshop or warehouseDecanting into smaller containers without tilting or opening the drumDrums with G2-inch threads in the chemical industry and in tradeTechnical detailsMaterialStainless steel 1.4301 (V2A), polytetrafluoroethylene (PTFE)Drive typemanually operatedPump typePressure pumpThreadG 2 inches, external threadFlow rate approx.10 l/minViscosity up to approx.500 mPa·sPipe diameter15 mmImmersion tube diameter15 mmLength of outlet bend185 mmOuter diameter of outlet12 mmMax. immersion depth60 cmFor containers up toapprox. 60 lScope of deliveryHand pump with fixed spout and shut-off valveService and procurementBusinesses with multiple drum sizes or container types often coordinate their order with the appropriate foot-operated or mini version, so that the right pump is to hand for every container.
