IKA Recirculating Chiller RC 2 lite, Compact Laboratory Chiller, 400 W Cooling Capacity, 0025006624
Anyone who operates a rotary evaporator, a jacketed vessel or a reflux condenser knows the problem of the open tap water circuit: as the outside temperature rises, the cooling effect falls, and water consumption drives up costs and effort. The IKA RC 2 lite recirculating chiller replaces this open circuit with a closed, PID-controlled refrigeration circuit and delivers up to 400 watts of cooling capacity at 20 degrees Celsius, constant and independent of the season or the water pressure in the laboratory. Cooling capacity from room temperature down to minus 10 degrees Celsius The cooling capacity of the RC 2 lite falls as expected as the target temperature drops: 400 watts at 20 degrees, 350 watts at 10 degrees, 250 watts at 0 degrees and still 140 watts at minus 10 degrees Celsius. The working temperature range extends from minus 10 degrees Celsius to room temperature, and with an external heater the bath can additionally be operated up to 70 degrees Celsius. Control is handled by a PID controller with a PT1000 sensor and LED display. The temperature stability is ±0.5 kelvin according to DIN 12876, and the display resolution and setting accuracy are each 0.1 kelvin. Natural refrigerant R290 to DIN 12876 Class I The refrigerant used is R290, a natural, halogen-free hydrocarbon refrigerant, filled with 76 grams at a maximum permissible pressure of 21 bar. According to DIN 12876, the RC 2 lite is classified as Class I with the marking NFL and is therefore intended for operation with non-flammable liquids. Practical note: R290 (propane) is itself flammable, so, as with all laboratory equipment using a hydrocarbon refrigerant, we recommend a sufficiently ventilated installation location without open ignition sources in the immediate vicinity of the unit. Recirculating chiller, circulating thermostat or heating bath: choosing the right design Within the IKA temperature control family, three designs can be distinguished: pure recirculating chillers such as the RC 2 lite only cool, refrigerated heating circulators such as the HRC 2 series cool and heat in one unit, and heating baths such as the HB digital heat without an active cooling function. The following overview compares the cooling capacity at different target temperatures: ModelDesign20 °C10 °C0 °C-10 °CHeating power RC 2 lite (this product)Recirculating chiller400 W350 W250 W140 Wnone (external heater up to 70 °C possible) RC 2 basicRecirculating chiller400 W370 W320 W240 Wnone HRC 2 liteCirculating thermostat400 W350 W250 W100 W1000 W HRC 2 controlCirculating thermostat400 W370 W320 W240 W1500 W RC 2 lite, RC 2 basic or RC 2 GREEN control: the right specification level The RC 2 lite is the compact entry-level version of the IKA recirculating chiller series for pure cooling tasks down to minus 10 degrees Celsius, with the climate-friendly refrigerant R290. Anyone who prefers pure cooling with the synthetic refrigerant R134a and a cooling capacity of 400 watts will find it in the IKA RC 2 basic. Anyone looking for a more powerful version will find it in the IKA RC 2 GREEN control, which likewise uses the natural refrigerant R290 and, according to IKA, has roughly double the output of the previous device generation. If the same unit has to heat actively as well as cool, for example for temperature cycles between minus 10 and 100 degrees Celsius, the IKA HRC 2 lite is the right choice. It is identical in construction to the RC 2 lite, but with an additional 1000-watt heater and an extended working range. Typical applications As an external cooling source with a closed circuit, the RC 2 lite is suitable for the following, among others: Cooling of rotary evaporators, for example the IKA RV 10 digital V-C or the IKA RV 3 V-C, as a replacement for the open tap water circuit Cooling of reflux condensers in syntheses and extractions Cooling source for devices that dissipate heat via a heat exchanger, for example double-walled grinding vessels, cooled incubators, laboratory reactors or cooling coils Connection, installation and ongoing operation The integrated pressure/suction pump reaches a maximum flow rate of 18 litres per minute at a maximum pump pressure of 0.35 bar on the pressure side and 0.15 bar on the suction side, connected via M16x1 threaded connections. The scope of delivery includes two hose nozzles for DN 8 hoses, which allow standard cooling water hoses to be connected directly. The filling volume of the internal bath is between 1 and 3.5 litres. RS232 and USB-B are available for connection to a PC or process control system, for example for logging temperature profiles. With a noise level of 51 dB(A) and a permissible duty cycle of 100 per cent, the RC 2 lite is designed for continuous operation in everyday laboratory use. The permissible ambient temperature range is 5 to 32 degrees Celsius at a maximum of 80 per cent relative humidity. Which cooling capacity for which rotary evaporator The decisive factor in choosing the right cooling capacity is the target temperature of the respective evaporation process: if a cooling bath at around 0 degrees Celsius is sufficient, the RC 2 lite still has 250 watts of cooling capacity available, and at minus 10 degrees Celsius it is 140 watts. The lower the required target temperature or the higher the solvent throughput at the rotary evaporator, the more worthwhile it is to consider a more powerful specification level such as the RC 2 GREEN control. The pump capacity also plays a role when connecting external devices: a maximum flow rate of 18 litres per minute at 0 bar back pressure is sufficient for most laboratory reactors and rotary evaporators at a direct installation distance. With longer hose runs or several consumers connected in series, the actual flow rate falls accordingly because of the rising line resistance, so the shortest possible hose routing lets the full pump capacity reach the consumer.

At the end of its service life, the device must not be disposed of with household waste but must be taken to a separate collection point for waste electrical equipment. The refrigerant R290 contained in the refrigeration circuit must be removed professionally by an approved refrigerant recovery company before disposal. Frequently asked questions about the RC 2 lite Can the RC 2 lite also heat?No, the RC 2 lite is a pure recirculating chiller. Heating the bath above room temperature is only possible with an external heater up to a maximum of 70 degrees Celsius. If an integrated heater is required, the IKA HRC 2 lite is the suitable alternative. Which hoses fit the RC 2 lite?The pump connections are designed as M16x1 threads, and two hose nozzles for DN 8 hoses are included in the scope of delivery. Is R290 as a refrigerant harmless in everyday laboratory use?R290 is a natural but flammable hydrocarbon refrigerant. For operation, we recommend a sufficiently ventilated installation location without open ignition sources in the immediate vicinity, as is usual for all devices with this type of refrigerant. How loud is the RC 2 lite in continuous operation?The noise level is 51 dB(A), and the device is designed for a duty cycle of 100 per cent. Can the RC 2 lite be integrated into laboratory software?Yes, the existing RS232 and USB-B interfaces allow the device to be connected to a PC or process control system. How does the RC 2 lite differ from the RC 2 GREEN control?Both are pure recirculating chillers with the natural refrigerant R290. The RC 2 GREEN control is the higher-specification, current version with, according to IKA, roughly double the output of the previous device generation, while the RC 2 lite is positioned as a compact entry-level model for applications down to minus 10 degrees Celsius. Is the pump capacity sufficient for several connected devices?The maximum flow rate of 18 l/min at 0 bar back pressure applies to a direct connection. With longer hose runs or several consumers in series, the flow actually available falls because of the line resistance, so a short hose routing is preferable.

IKA C-MAG HP 7 Hotplate, Ceramic Surface 180 x 180 mm, Without Stirring Function, 0003581800
Not every workstation needs a stirrer as well, for example when stirring is done externally and a water bath is only to be temperature-controlled or a vessel is only to be heated. The IKA C-MAG HP 7 (0003581800) is a hotplate without magnetic stirring function, with 1000 watts of heating power, a ceramic surface measuring 180 x 180 millimetres and a heating temperature range of 50 to 500 degrees Celsius. It is technically derived from the proven C-MAG HS series, but without the stirring drive. 1000 watts of heating power without stirring function The ceramic plate transfers the heating power directly to the vessel placed on it and covers a temperature range of 50 to 500 degrees Celsius, set with a rotary knob with an accuracy of 5 Kelvin. According to the data sheet, the heating rate is 5 Kelvin per minute, a guide value for estimating how quickly a given volume of water reaches the set temperature. As no stirring drive is fitted, the otherwise usual speed scale is omitted and operation is limited to setting the temperature. According to the manufacturer, a volume of up to 10 litres of water can be heated with it. Can be extended with external temperature measurement in the medium Via the connection socket according to DIN 12878, an ETS-D5 contact thermometer can be retrofitted to measure the temperature directly in the medium instead of only at the plate surface, which is practical for oil baths, for example, or when an externally driven stirrer is already part of the setup. The sensor itself is not included in the scope of delivery. Compact design for integration into existing setups With dimensions of 220 x 105 x 330 millimetres and a weight of 4.4 kilograms, the HP 7 can be integrated into existing experimental setups without taking up much space, for example underneath a stand with a separate stirrer or as a plain heat source for an oil bath, without having to allow extra space for a stirring unit. Protection class IP 21 protects against vertically falling water drops. Easy integration into existing setups Because the electronics of the HP 7 are designed exclusively for the heating function, operation is reduced to a single rotary knob for the set temperature, with no scale or control for a speed that does not exist anyway. This makes the unit an uncomplicated addition to setups in which a separate stirrer, for example an overhead stirrer with its own stand, is already available and only a reliable heat source underneath is missing. Typical applications As a hotplate without stirring function, the C-MAG HP 7 is technically suited for: Heating vessels and oil baths without a simultaneous need for stirring Combination with separately driven stirrers, for example overhead stirrers Temperature control of reaction blocks or carrier plates from the IKA accessories range Simple heat source in teaching and training laboratories Replacement purchase for workstations where a separate stirrer is already available Selection guide: hotplate only or heating magnetic stirrer Within the C-MAG family, IKA basically distinguishes between HS models with stirring and heating and HP models with heating function only: ModelStirringVolume (H2O)Heating powerPlate size C-MAG HP 7 (this unit)no10 l1000 W180 x 180 mm C-MAG HP 4no5 l250 W100 x 100 mm C-MAG HS 7yes, 100 to 1500 rpm10 l1000 W180 x 180 mm C-MAG HS 10yes, 100 to 1500 rpm15 l1500 W260 x 260 mm If stirring is done anyway or a stirrer is not needed at all, the hotplate only saves purchase costs compared with an HS model with the same heating rating. As soon as stirring and heating are required together in one unit, one of the HS models is the more suitable choice. Differences from the heating magnetic stirrers and the smaller HP 4 The IKA C-MAG HP 4 covers smaller volumes of up to 5 litres with a smaller plate area and 250 watts of heating power and does not have a connection for an external contact thermometer. If stirring is required in addition to heating, the IKA C-MAG HS 7 and the IKA C-MAG HS 10 offer the same heating technology with an integrated stirring drive. For larger heating surfaces of up to 260 x 260 millimetres, IKA also offers the C-MAG HP 10 as a hotplate only, and for smaller batches the C-MAG HS 4 is available as a more compact alternative with stirring function. Technical details Number of heating positions1 Heating power1000 W Heating temperature range50 to 500 °C, rotary knob, setting accuracy 5 K Connection for external temperature sensorETS-D5 (DIN 12878) Volume max.10 l Heating rate5 K/min Surface materialCeramic Surface dimensions180 x 180 mm Permissible relative humidity80 % Dimensions (W x H x D)220 x 105 x 330 mm Weight4.4 kg Protection classIP 21 (DIN EN 60529) Mains connection230 V, 50/60 Hz, 1005 W (other voltage variants 120 V / 100 V available) Scope of delivery 1 x IKA C-MAG HP 7 Hotplate (0003581800) Stirring bars are not included, as the C-MAG HP 7 has no stirring function. An external temperature sensor such as the ETS-D5 is likewise not included in the scope of delivery. Use, installation, maintenance and disposal With protection class IP 21, the C-MAG HP 7 is protected against vertically falling water drops and is designed for operation in a fume hood or on a stable, level laboratory bench at up to 80 percent relative humidity. As no stirrer is fitted, the plate is particularly suitable for installation underneath separate stirring drives or stands. Sufficient clearance for cables and accessories should be ensured here. The ceramic surface is chemically resistant but should be allowed to cool before cleaning. At the end of its service life, the hotplate, as an electrical appliance, does not belong in household waste but in separate collection of waste electrical equipment; the manufacturer's WEEE registration number is DE 66784213. Cost logic: when it pays to do without a stirring function If a separate stirrer, for example an overhead stirrer, is already in use, or if no stirring is needed for the application at all, the hotplate only saves noticeable purchase costs compared with an HS model with identical heating power, without compromising on the actual heating function. This applies in particular when several workstations with different stirrers are to use the same heating power, for example in practical course rooms with permanently mounted stands. For standard workstations where stirring and heating are typically needed together, an HS model is usually the more economical overall solution, because it makes an additional stirrer unnecessary. Individual requirements & procurement service For the C-MAG HP 7, suitable original accessories are available on request, such as the ETS-D5 contact thermometer, stand material, carrier plates, oil bath attachments and reaction blocks of different volumes. Through our procurement service we also support you with spare parts, calibrations and the assembly of several workstations with uniform accessories. For further information and contact options, see lt-laborhandel.com/service. Frequently asked questions Can the C-MAG HP 7 also stir?No, the HP 7 is a hotplate without magnetic stirring drive. The HS models of the C-MAG series are available for this. Is an external temperature sensor included in the scope of delivery?No, the connection socket according to DIN 12878 is present, but an ETS-D5 contact thermometer has to be purchased separately. How does the HP 7 differ from the smaller HP 4?With 1000 instead of 250 watts, the HP 7 offers a considerably higher heating power, a larger plate of 180 x 180 millimetres and, in addition, a connection for an external contact thermometer, which the HP 4 does not have. What is the maximum volume that can be heated?According to the manufacturer, up to 10 litres of water. Is the HP 7 suitable for an oil bath?The hotplate itself is designed for direct heat transfer to vessels placed on it. For oil bath applications, IKA offers suitable oil bath attachments in its accessories range, which can be placed on the 180 x 180 millimetre plate. Does accessory equipment from the HS series also fit the HP 7?Carrier plates, reaction blocks and oil bath attachments from the IKA accessories range are designed for the 180 x 180 millimetre surface of the HP 7 and are generally also compatible with other C-MAG models of the same plate size, for example the C-MAG HS 7. How is the C-MAG HP 7 disposed of properly?As an electrical appliance, it belongs at a collection point for waste electrical equipment rather than in household waste. The manufacturer's WEEE registration number is given in the section Use, installation, maintenance and disposal.
LAUDA Hydro H 24 Water Bath, 25 to 100 °C, up to 20.9 L, Bath Dimensions 600 x 245 mm, L002904
If a large number of vessels need to be heated to the same temperature at the same time, it is primarily the width of the bath opening that determines how many of them can fit in at once. Measuring 600 x 245 millimetres, the LAUDA Hydro H 24 has the widest bath opening in the Hydro series, with a bath depth of 165 millimetres, the same as the Hydro H 8 and H 16. The bath volume ranges from 11.3 to 20.9 l, and the temperature is controlled within the standard operating range of 25 to 100 °C with a temperature stability of ± 0.1 K.Space for many vessels in a rowThe 600-millimetre-wide surface allows significantly more vessels to be placed side by side than with the smaller models in the series, for example, a row of beakers, narrow-necked flasks or sample containers. With a bath depth of 165 millimetres, the Hydro H 24 is particularly suitable for vessels that do not need to be fully submerged. The maximum heating power is 1.5 kilowatts.Uniform temperature across the entire surfaceTemperature control is handled by a 1-point controller, operated via a TFT colour display showing readings in °C or °F. Setpoints are entered in increments of 0.1 °C via a membrane keypad, whilst a timer set in hours and minutes covers three application-specific time functions. In the event of low water level, over- or under-temperature, or in the event of a sensor failure or short circuit, the unit triggers a visual and audible alarm; the trigger points can be adjusted within a range of ± 10 K. The controller’s electronic function monitoring runs continuously.Robust construction for continuous operationThe bath body, cover frame, sieve base and heating element are made of stainless steel; a drain tap on the bath vessel simplifies water changes given the large surface area. The double-walled, internally domed lid insulates the heat along its entire length and channels condensation away along the dome. The lid and sieve tray are included as part of the scope of delivery.Handling in everyday laboratory useGiven the wide surface area, it is advisable to establish a fixed arrangement for the vessels so that the same volume of water always circulates around each vessel and the temperature remains consistent across the entire row. The drain tap is located at the narrow end of the bath and remains easily accessible even when the bath is fully loaded. Weighing around 18 kilograms, the Hydro H 24 is best placed in a fixed, stable location rather than being moved frequently.Typical applicationsSimultaneous temperature control of multiple vessels in series experimentsBatch testing with a consistent temperature across the entire bath widthQuality assurance with high sample throughputApplications in research and development laboratories with a high demand for vesselsSelection guide: width or depth requiredIf only a few vessels are required, the more compact Hydro H 8, with a bath opening of just 245 x 200 millimetres, is sufficient. For a moderate number of vessels with the same bath depth of 165 millimetres, the narrower Hydro H 16 with a 400 x 245 millimetre opening is suitable. If vessels need to be fully submerged rather than placed side by side, the Hydro H 22, with a bath depth of 225 millimetres instead of 165 millimetres, is better suited to these requirements, whilst offering the same opening width as the Hydro H 16. The largest model in the range, the Hydro H 41, combines greater depth with a bath volume of up to 37.9 l, making it equally suitable for large batches and tall vessels.Technical detailsOperating temperature range25 to 100 °CAmbient temperature range10 to 40 °Ctemperature stability± 0.1 KMax. heating power1.5 kWBath dimensions (W x D x H)600 x 245 x 165 mmTank capacity min. / max.11.3 / 20.9 LOverall dimensions (W x D x H)700 x 440 x 275 mmWeight (net)18 kgMains supply230 V, 50/60 HzMains plugMains cable with angled Schuko plug (CEE7/7)Scope of deliveryLAUDA Hydro H 24 water bath with drive and control unit, order number L002904Stainless steel lid, double-walled with an inner curveStainless steel mesh baseMains cable with angled Schuko plug (CEE7/7)Regulatory informationThis appliance is an electrical appliance within the meaning of the German Electrical and Electronic Equipment Act (ElektroG).

IKA CBC VISC lite Refrigerated and Heating Bath Circulator, -25 to 125 °C, for ROTAVISC Viscometers, 20102007
Rotational viscometers only deliver reliable measured values if the sample stays precisely temperature-controlled during the measurement. The IKA CBC VISC lite (0020102007) is a refrigerated and heating bath circulator designed specifically for combination with IKA ROTAVISC rotational viscometers, with a working temperature range of -25 °C to 125 °C and space for two standard beakers in the open bath. While one sample is being measured in the bath, a second one can already be pre-conditioned, which saves waiting time in measurement series with several samples. Temperature range and control accuracy for viscosity measurement The heating power of 2,000 watts and a cooling capacity of 450 watts at 20 °C to 120 watts at -20 °C cover the working temperature range of -25 °C to 125 °C. The temperature stability to DIN 12876 is ±0.05 kelvin both at 70 °C and at -10 °C, controlled by a PID controller with PT1000 working and safety probes. This stability is important in viscosity determination, because the viscosity of many media depends strongly on temperature and even small temperature fluctuations can falsify the measured values. Environmentally friendly refrigerant and optimised water flow The natural, environmentally friendly R290 is used as refrigerant, with a fill quantity of 48 grams, designed for a maximum pressure of 21 bar. Optimised water flow management in the insulated bath ensures fast and precise temperature control. The noise level is 53 dB(A), and an air filter that is easy to remove and clean keeps the cooling performance constant over time. External pump connection for standard vessels to DIN Via the external pump connection, the CBC VISC lite can also be used to heat standard vessels to DIN for absolute viscosity determination with ELVAS spindles or for double-walled beakers. The pressure/suction pump reaches a maximum delivery pressure of 0.35 bar, a suction pressure of 0.15 bar and a flow rate of up to 18 litres per minute via the M16x1 connection. The fill volume of the bath is 5.5 to 8.5 litres, the bath opening measures 150 x 218 millimetres and the total height of the bath is 234 millimetres. The CBC VISC lite can thus be used flexibly both for direct measurement in the open bath and for temperature control of an external, closed test vessel, depending on which specific measurement method the respective viscosity determination requires in each case. Compact design for the workstation at the viscometer With external dimensions of 414 x 392 x 505 millimetres and a weight of 29 kilograms, the CBC VISC lite is considerably more compact than the CBC 5 series and is designed for installation directly next to a ROTAVISC viscometer. The IP 21 protection class and the permissible ambient temperature range of 5 to 32 °C at up to 80 % relative humidity cover the usual laboratory conditions. The device can be connected to a PC via the USB and RS 232 interfaces. Safety classification and insulation of the bath To DIN 12876, the CBC VISC lite is classified in safety class III with the marking FL, and the adjustable safety circuit ranges from 0 to 135 °C. The insulated bath reduces heat loss to the outside and, together with the optimised water flow management, helps set temperatures to remain stable even over longer measurement series, without the ambient temperature in the laboratory influencing the measurement. For measurement series with frequently changing temperature steps, this combination of fast control and stable insulation is a practical advantage over open, uninsulated water baths. Typical applications As a bath circulator tailored specifically to viscosity measurement, the CBC VISC lite is used above all where temperature stability and sample throughput have to work together: Temperature control of samples for rotational viscometers of the ROTAVISC series directly in the open bath Parallel pre-conditioning of a second sample while the first is already being measured Absolute viscosity determination with ELVAS spindles in standard vessels to DIN via the external pump connection Temperature-dependent viscosity series over a wide range from -25 °C to 125 °C Quality control and research in the coatings, paint and food industries, where viscosity is recorded as a test parameter Technical details Device typeRefrigerated and heating bath circulator Class to DIN 12876III (FL) RefrigerantR290, 48 g, max. 21 bar Heating power2,000 W Cooling capacity at 20 °C / 10 °C / 0 °C / -10 °C / -20 °C450 W / 420 W / 380 W / 250 W / 120 W Working temperature range-25 °C to 125 °C Temperature stability to DIN 12876 (at 70 °C and -10 °C)±0.05 K Temperature controlPID controller, PT1000 working and safety probes DisplayLED Adjustable safety circuit0 to 135 °C Bath fill volume5.5 to 8.5 l Bath opening (W x D) / total bath height150 x 218 mm / 234 mm Pump typePressure/suction pump Max. pump pressure / max. suction pressure0.35 bar / 0.15 bar Max. flow rate18 l/min Pump connectionM16x1 Noise level53 dB(A) Dimensions (W x H x D)414 x 392 x 505 mm Weight29 kg Protection class to DIN EN 60529IP 21 Permissible ambient temperature / rel. humidity5 to 32 °C / 80 % InterfacesUSB, RS 232 Power supply230 V, 50/60 Hz Power consumption2,320 W Scope of delivery 1 x IKA CBC VISC lite Refrigerated and Heating Bath Circulator Individual requirements and procurement service To connect the CBC VISC lite to ROTAVISC viscometers or to external standard vessels, we support you through our procurement service in selecting suitable ELVAS spindles, hose sets and heat transfer fluids.

LAUDA Hydro H 16 Water Bath, 25 to 100 °C, up to 13.9 L, Bath Dimensions 400 x 245 mm, L002902
If several Erlenmeyer flasks or a row of beakers are to be temperature-controlled at the same time, the size of the bath opening becomes the decisive factor. Measuring 400 x 245 millimetres, the LAUDA Hydro H 16 has a significantly wider opening than the smaller models in the series, whilst maintaining the same bath depth of 165 millimetres. The bath volume ranges from 7.5 to 13.9 l; as with all Hydro water baths, the operating temperature range is from 25 to 100 °C with a temperature stability of ± 0.1 K.Wide bath opening for multiple vesselsThe 400 x 245 millimetre bath opening accommodates several narrow vessels side by side without them touching one another. With a depth of 165 millimetres, the bath is particularly suitable for shallower vessel shapes such as beakers, smaller Erlenmeyer flasks or sample bottles, which do not need to be fully submerged. The maximum heating power is 1.5 kilowatts, which is higher than that of the smaller Hydro H 8.Timer, alarms and digital setpoint adjustmentOperation is via a TFT colour display showing temperatures in °C or °F and a membrane keypad with clear symbols. Temperature values can be set in increments of 0.1 °C; a 1-point temperature controller then takes over regulation. The timer supports three application-specific time functions in hours and minutes. In the event of a water shortage, over- or under-temperature, or a sensor break or short circuit, the unit triggers a visual and audible alarm; the trigger points are adjustable within a range of ± 10 K.Robust construction in stainless steelThe bath body, cover frame, sieve base and heating element are made of stainless steel; the bath vessel has a drain tap for draining the water. The double-walled lid is domed on the inside and provides thermal insulation; as a result, condensation drips down the dome rather than running back into the open vessels. The lid and sieve tray are included as part of the scope of delivery.Handling in everyday laboratory useIf several vessels are placed on a single surface, it is worth checking their arrangement to ensure that heat can circulate evenly around each vessel and that none of them touch one another. The drain tap makes changing the water easier, even though the larger volume of up to 13.9 l means slightly more water needs to be drained than with the smaller Hydro H 8. Weighing around 14 kilograms, the bath can still be placed on the laboratory bench by a single person.Typical applicationsSimultaneous temperature control of several beakers or small Erlenmeyer flasksRoutine experiments in chemical process engineering involving multiple vesselsPreparation and sample processing in research and development laboratoriesScreening tests with a consistently repeated temperatureSelection guide: is a depth of 165 millimetres sufficient?If you only need a few small vessels, the more compact Hydro H 8 with its small 245 x 200 millimetre opening will suffice. If, with the same opening, greater depth is required for taller vessels, the Hydro H 22 - with a bath depth of 225 millimetres (instead of 165 millimetres) and a volume of up to 20.3 l, is the right choice. For an even wider opening of 600 x 245 millimetres, in which many vessels can be arranged in a row, the Hydro H 24 is ideal. The largest model in the range, the Hydro H 41, holds up to 37.9 l for large batches.Technical detailsOperating temperature range25 to 100 °CAmbient temperature range10 to 40 °Ctemperature stability± 0.1 KMax. heating power1.5 kWBath dimensions (W x D x H)400 x 245 x 165 mmTank capacity (min./max.)7.5 / 13.9 LOverall dimensions (W x D x H)500 x 440 x 275 mmWeight (net)14 kgMains supply230 V, 50/60 HzMains plugMains cable with angled Schuko plug (CEE7/7)Scope of deliveryLAUDA Hydro H 16 water bath with drive and control unit, order number L002902Stainless steel lid, double-walled with an inner curveStainless steel sieve trayMains cable with angled Schuko plug (CEE7/7)Regulatory informationThis appliance is an electrical appliance within the meaning of the German Electrical and Electronic Equipment Act (ElektroG).

LAUDA Alpha A Immersion Circulator, 25 to 100 °C, Bath Volume up to 50 L, L000618
Not every laboratory or workshop needs a completely new bath thermostat with its own vessel. Often, a tank, basin or water bath is already available, but lacks a temperature control system. The LAUDA Alpha A is an immersion circulator designed precisely for this purpose: using the screw clamp supplied, it is attached to an existing bath vessel and regulates the temperature within it between 25 and 100 °C, without the need to purchase an additional vessel.Clamp mounting on existing containersThe screw clamp fits wall thicknesses of up to 30 millimetres; the immersion depth should be at least 150 millimetres. This allows the Alpha A to be attached to basins, tanks or vats with a volume of up to 50 l without being permanently installed. Once used in one location, the device can just as easily be moved to another bath vessel, which saves time when tasks change or there are multiple locations within the operation.Display and operationA single-line LED display shows either the actual or the setpoint value; operation is via three buttons and a simple menu system. According to the data sheet, the fully electronic, continuous controller maintains the temperature with a stability of ± 0.05 K. The operating temperature range is from 25 to 100 °C, whilst the permissible ambient temperature is between 5 and 40 °C. This range is sufficient for most aqueous and oil-based temperature baths used in everyday laboratory work.Pump and safety featuresThe built-in circulation pump delivers up to 15 l per minute at a maximum pressure of 0.2 bar; the flow rate can be reduced if a gentler flow is required in the bath. Low-level and over-temperature protection monitor operation with non-flammable liquids; in the event of a fault, the unit emits an audible and visual alarm. The maximum heating power is 1.5 kilowatts, the current consumption is 7 amperes, and the unit is connected via an angled Schuko plug.Typical applicationsRetrofitting temperature control to existing water baths, tanks or vatsImmersion baths in workshops and quality assurance, where a permanently installed bath thermostat is not practicalFlexible use with a variety of containers up to 50 lSupplementing existing systems without the need to purchase a separate bath vesselRetrofitting multiple containers at different locations using just a single drive unitHeating thermostat with its own bath or cooling thermostatIf no suitable vessel is available, or if the thermostat is to be used permanently with its own bath, the LAUDA Alpha A 6, Alpha A 12 and Alpha A 24 heating thermostats are the more suitable choice. They come with their own stainless steel bath vessel in three sizes ranging from 2.5 to 25 l. The Alpha A is not designed for active cooling below ambient temperature; in this case, the Alpha RA 8 refrigeration thermostat with compressor cooling takes on this task.Technical data in accordance with DIN 12876The technical data for the Alpha A are determined in accordance with DIN 12876, the standard for recirculating thermostats and bath thermostats in laboratory and industrial applications. This makes it possible to compare specifications relating to temperature stability, heating power and pump capacity across different manufacturers, which is helpful during audits and interlaboratory tests in quality management.Connection for different mains voltagesThe Alpha A operates as standard at 220 volts at 60 hertz or 230 volts at 50 hertz, thus covering the standard European mains supplies; it is connected via an angled Schuko plug. For export, variants with 100-volt and 115-volt mains plugs (NEMA5-15P in each case) as well as with a British BS1363 plug are also available under separate order numbers.Technical detailsOperating temperature range25 to 100 °CAmbient temperature range5 to 40 °Ctemperature stability± 0.05 KMax. heating power1.5 kWMax. power consumption1.5 kWCurrent consumption7 AMax. pump pressure0.2 barMax. pump flow rate15 L/minBath volumeup to 50 L, suspended operation in an existing bath vesselSuitable bath vesselsWall thickness up to 30 mm, immersion depth at least 150 mmDimensions (W x D x H)125 x 150 x 300 mmWeight4 kgMains supply220 V; 60 Hz / 230 V; 50 HzMains plugSchuko (CEE7/7), angledStandardTechnical data in accordance with DIN 12876Scope of deliveryLAUDA Alpha A immersion circulator, order number L000618Screw terminal for mounting on existing bath vesselsMains cable with angled Schuko plugOperating instructions as a PDF downloadRegulatory informationThis device is an electrical appliance within the meaning of the German Electrical and Electronic Equipment Act (ElektroG).

IKA HRC 2 lite Circulator, Cooling/Heating -10 to 100 °C, R290, 0020104311
Some applications need both cooling and heating in the same series of experiments, for example when a bioreactor first has to be cooled down to 5 degrees Celsius and then heated to 80 degrees Celsius. The IKA HRC 2 lite covers exactly this case: as a refrigerated and heating circulator it works in the range from minus 10 to 100 degrees Celsius, with the natural refrigerant R290 and a heating power of 1000 watts in a compact benchtop unit. One unit for cooling and heating from minus 10 to 100 degrees Celsius The cooling capacity is 400 watts at 20 degrees Celsius and falls with decreasing target temperature to 350 watts at 10 degrees, 250 watts at 0 degrees and 100 watts at minus 10 degrees Celsius. For the opposite direction, a heating power of 1000 watts is available. The temperature stability to DIN 12876 is ±0.1 kelvin in the colder range around minus 10 degrees Celsius and improves to ±0.05 kelvin at plus 70 degrees Celsius. Control is by PID controller with a PT1000 working temperature sensor and a separate PT1000 safety temperature sensor, and the LED display provides a resolution of 0.1 kelvin with the same setting accuracy. Safety functions and refrigerant R290 The HRC 2 lite has visual and acoustic warning functions as well as its own over-temperature warning, and the safety circuit is adjustable between 0 and 110 degrees Celsius. To DIN 12876 the unit is classified as Class II with the designation FL, which makes it suitable for operation with flammable liquids as long as there is a sufficient safety margin between the flash point and the set maximum temperature. The refrigerant used is R290, with a fill of 79 grams at a maximum permissible pressure of 21 bar. Practical note: R290 (propane) is a natural but flammable hydrocarbon refrigerant, so, as is usual for all laboratory equipment with this type of refrigerant, we recommend a sufficiently ventilated installation location without open ignition sources in the immediate vicinity of the unit. HRC 2 lite or HRC 2 control: choosing the right specification level The HRC 2 lite and the IKA HRC 2 control share the operating principle of a refrigerated and heating circulator, but differ clearly in equipment and specifications: the HRC 2 lite uses the natural refrigerant R290 instead of the synthetic R134a of the HRC 2 control, is classified as Class II instead of Class III to DIN 12876 and delivers 1000 instead of 1500 watts of heating power, with a somewhat narrower working temperature range of minus 10 to 100 degrees Celsius instead of minus 30 to 100 degrees Celsius. In addition, the HRC 2 lite does without the analogue output of the HRC 2 control and is limited to RS232 and USB-B. The HRC 2 control itself has been discontinued since 31 July 2026, and its successor is the IKA HRC 2 GREEN control with the natural refrigerant R290. If cooling only is needed, without a heating function, the dedicated recirculating chiller IKA RC 2 lite is the leaner and technically closely related alternative, with the same housing and the same pump but without a heating element. If, conversely, only heating is needed, without active cooling, a simple IKA HB digital heating bath is often sufficient. Typical applications As a refrigerated and heating circulator with a wide temperature range, the HRC 2 lite is suitable, among other things, for: Temperature control of laboratory reactors and bioreactors over changing temperature cycles from cold to warm Temperature control of open baths for sample preparation or reaction control Temperature control source for connected measuring instruments that need a stable reference temperature Use as a peripheral device with device-to-device communication via RS232 or USB to main units, as well as control and monitoring via laboratory software Connection, installation and ongoing operation The integrated pressure/suction pump reaches a maximum flow rate of 18 litres per minute at a maximum pump pressure of 0.35 bar on the pressure side and 0.15 bar on the suction side, connected via M16x1 threaded connections. The scope of delivery includes two olives for DN 8 hose connections and a USB-A-B cable for direct PC connection. The filling volume of the internal bath is between 1 and 3.5 litres, and a calibration option is available to check the temperature display regularly against a reference sensor. For continuous operation the HRC 2 lite is designed for a permissible duty cycle of 100 percent and remains comparatively quiet at 51 dB(A); the permissible ambient temperature range is 5 to 32 degrees Celsius at a maximum of 80 percent relative humidity. One unit instead of two: when the dual function pays off Anyone who regularly has to run both cooling and heating cycles in the same experimental set-up saves one unit space and one additional hose connection with the HRC 2 lite, compared with a combination of a separate recirculating chiller and heating bath. For applications that only ever cool or only ever heat, on the other hand, the respective specialised single unit is often the more economical choice, as the heating power of 1000 watts and the cooling capacity steps down to 100 watts at minus 10 degrees Celsius represent compromises compared with the respective specialised units. As for the pump design, the same applies as for all units in this series: the maximum flow rate of 18 l/min is only reached with short hose runs without significant back pressure, and longer lines or several connected consumers reduce the flow that actually arrives in line with the increasing line resistance.

At the end of its service life the unit must not be disposed of with household waste but must be taken to a separate collection for waste electrical equipment. The refrigerant R290 contained in the refrigerant circuit must be removed by an approved refrigerant recovery company before disposal. Frequently asked questions about the HRC 2 lite What is the difference between the HRC 2 lite and the HRC 2 control?The HRC 2 lite uses R290 instead of R134a, is classified as Class II instead of Class III to DIN 12876, delivers 1000 instead of 1500 watts of heating power, covers a somewhat narrower working range of minus 10 to 100 degrees Celsius and does without the analogue output of the HRC 2 control. The HRC 2 control has been discontinued since 31 July 2026, and its successor is the IKA HRC 2 GREEN control. Can the HRC 2 lite also be used as a pure chiller without a heating function?Technically yes, the heating function can simply be left unused. If only cooling is needed permanently, the identical-design IKA RC 2 lite without a heating element is usually the more economical choice. Which hoses fit the HRC 2 lite?Connection is via M16x1 thread, and two olives for DN 8 hose connections are supplied with the unit to match. Do I need to observe anything special with the refrigerant R290?Yes, R290 (propane) is flammable, even though it counts as a natural refrigerant. A well-ventilated installation location without ignition sources in the immediate vicinity of the unit is therefore usual and sensible. Why is the DIN 12876 designation FL important?It indicates that the unit is also suitable for operation with flammable liquids as the bath medium, provided their flash point maintains a sufficient safety margin to the set maximum temperature. Can the HRC 2 lite be calibrated?Yes, the unit has a calibration option to check the temperature display regularly against a reference sensor. How loud is the HRC 2 lite in continuous operation?At 51 dB(A) the unit remains pleasantly quiet even in continuous operation at a permissible duty cycle of 100 percent. Individual requirements & procurement service For suitable connection hoses, additional valves, adapters or connection to existing laboratory and bioreactors, our procurement service will support you.

IKA C-MAG HP 4 Hotplate, Ceramic Support Surface 100 x 100 mm, 250 Watt, 0003581600
For a single flask, a small Petri dish or occasional heating without much space requirement, a full-sized hotplate is often not worthwhile. The IKA C-MAG HP 4 (0003581600) is the most compact pure hotplate of the C-MAG family, with a ceramic support surface of just 100 x 100 millimetres, 250 watts of heating power and a weight of only 2.44 kilograms. Compact ceramic support surface for small vessels The ceramic support surface of 100 x 100 millimetres is deliberately designed for smaller vessels and volumes of up to 5 litres of water and covers a heating temperature range of 50 to 500 degrees Celsius, set via a simple rotary knob with a setting accuracy of 5 kelvin, without the additional display and control functions of the larger HS models. With 250 watts of heating power, the heating rate is 2.5 kelvin per minute, lower than with the larger C-MAG HP models, but sufficient for smaller batches and spot heating. Lightweight for mobile use With dimensions of 150 x 105 x 260 millimetres and a weight of only 2.44 kilograms, the HP 4 can easily be moved between workstations or accommodated in small fume cupboards where there is no room for larger hotplates. The protection class IP 21 protects against vertically falling drops of water. No option for external temperature measurement Unlike the larger C-MAG HP and HS models, the HP 4 has no connection for an external contact thermometer according to the technical data table. Temperature control takes place exclusively via the plate surface, a deliberate omission in favour of the compact, simple design. For applications in which the exact temperature in the medium itself must be documented, this is a relevant exclusion criterion that should be checked before purchase. Economical entry into the C-MAG series With 250 watts of heating power, the HP 4 is well below the 1000 watts of the C-MAG HP 7 and HS models, and the purchase price and the running power consumption in continuous operation across several workstations are correspondingly lower. For laboratories that have to equip several workstations with simple heating tasks without every position needing high heating power or a sensor socket, the HP 4 allows a larger number of positions to be equipped at reasonable cost. Typical applications As the most compact and lightest hotplate of the C-MAG family, the HP 4 is technically suited above all to small-volume, non-critical heating tasks: Heating individual small vessels up to 5 litres volume Workstations with limited space, for example in small fume cupboards Simple heat source in training and routine laboratories without any requirement for medium temperature measurement Second device for spot heating tasks alongside a larger main device Mobile use thanks to a low weight of 2.44 kilograms Selection guide: HP 4 compared with larger C-MAG hotplates Within the C-MAG HP series, the HP 4 marks the entry point, with clear differences in surface area, power and sensor connection: ModelPlate sizeVolume (H2O)Heating powerExternal sensor C-MAG HP 4 (this device)100 x 100 mm5 l250 Wnot provided C-MAG HP 7180 x 180 mm10 l1000 WETS-D5 (DIN 12878) Anyone who wants to heat larger vessels or use external temperature measurement in the medium is better served by the C-MAG HP 7. For small, non-critical heating tasks with limited space, the HP 4 remains the more compact and more economical choice, especially if several workstations are to be equipped in parallel with simple heating tasks without every position needing a connection to an external contact thermometer. Differentiation from the larger HP 7 and from heating magnetic stirrers The IKA C-MAG HP 7 offers, with 1000 watts of heating power, a larger surface and a connection for an external contact thermometer, considerably more reserves for larger volumes. If stirring is required in addition to heating, the IKA C-MAG HS 7 or, for very small volumes, the mini magnetic stirrer topolino are the more suitable devices, although the latter has no heating function. Technical details Number of heating positions1 Heating power250 W Heating temperature range50 to 500 °C, rotary knob, setting accuracy 5 K Max. volume5 l Heating rate2.5 K/min Support surface materialCeramic Support surface dimensions100 x 100 mm Permissible relative humidity80 % Dimensions (W x H x D)150 x 105 x 260 mm Weight2.44 kg Protection classIP 21 (DIN EN 60529) Mains connection230 V, 50/60 Hz, 255 W (other voltage variants 120 V / 100 V available) Scope of delivery 1 x IKA C-MAG HP 4 hotplate (0003581600) Stirring bars are not included, as the C-MAG HP 4 has no stirring function. A connection for an external contact thermometer is not provided on this model. Application, installation, maintenance and disposal With protection class IP 21, the C-MAG HP 4 is protected against vertically falling drops of water and is designed for operation in a fume cupboard or on a stable laboratory bench at up to 80 per cent relative humidity. Because of its compact design and low weight, the plate is also suitable for mobile use between several workstations or for transport between different rooms and floors, but it should be cooled down and disconnected from the mains before being moved. The ceramic surface is chemical-resistant, but should be allowed to cool and be disconnected from the mains before cleaning. At the end of its service life, the hotplate, as an electrical device, does not belong in household waste but in the separate collection of waste electrical equipment; the manufacturer's WEEE registration number is DE 66784213. Investment logic: when the compact HP 4 is sufficient For small vessels up to 5 litres, spot heating without any requirement for a temperature measured in the medium, and cramped space conditions, the HP 4 is the most economical solution within the C-MAG family and covers a large part of simple laboratory routines without power reserves remaining unused. As soon as larger volumes, more heating power or external temperature measurement are needed, there is no way around the C-MAG HP 7 or an HS model with stirring function, and the additional cost is then covered by the additional range of functions. For training laboratories with many parallel but non-critical workstations, purchasing several HP 4 units can make more sense than a few larger hotplates. Individual requirements & procurement service Suitable original accessories such as fixing elements and holders are available for the C-MAG HP 4 if required, as are certificates and attestations for qualification documentation according to IQ/OQ, for example for regulated quality control environments. Through our procurement service, we also support you with spare parts, calibrations and the configuration of several workstations with uniform accessories. You will find further information and contact options at lt-laborhandel.com/service. Frequently asked questions What vessel sizes is the 100 x 100 millimetre plate designed for?The surface is designed for smaller standard vessels such as Erlenmeyer flasks, beakers or Petri dishes up to a volume of 5 litres and thus offers sufficient support area for most routine small-scale batches. Can the C-MAG HP 4 also stir?No, the HP 4 is a pure hotplate without a magnetic stirring drive. For stirring and heating in one device, IKA offers the C-MAG HS series. Can an external temperature sensor be connected?No, according to the technical data table, the HP 4 has no connection for an external contact thermometer, unlike the larger HP 7. What is the maximum volume that can be heated?According to the manufacturer, up to 5 litres of water. How quickly does the plate heat up?According to the data sheet, the heating rate is 2.5 kelvin per minute, which is about half as fast as the more powerful C-MAG HP 7 at 5 kelvin per minute, but usually quick enough for small volumes. Which voltage variants are available?In addition to the standard 230 volt version, further voltage variants with 120 volts and 100 volts are available according to the data sheet, each at a mains frequency of 50 or 60 hertz. Is the HP 4 suitable for mobile use between workstations?With a weight of 2.44 kilograms and compact dimensions, the HP 4 can be moved comparatively easily. How is the C-MAG HP 4 disposed of properly?As an electrical device, it belongs at a waste electrical equipment collection point instead of in household waste. The manufacturer's WEEE registration number is given in the section Application, installation, maintenance and disposal.

IKA HB digital Heating Bath, 4 Litre, Water/Oil, 180 °C, 0020016334
Not every temperature control task in the laboratory requires compressor cooling. Where only a heating bath up to 180 degrees Celsius is needed, for example for extractions, solvent evaporation or viscosity measurements at elevated temperature, a plain heating bath is sufficient. The IKA HB digital provides 1400 watts of heating power, a capacity of up to 4 litres and a stainless steel vessel (material 1.4404) in contact with the product, which works with both water and silicone oil as the temperature control medium. As an open bath without an integrated circulation pump, it is aimed at anyone looking for a reliable, easy-to-use heating bath for direct use, without needing the additional equipment of an external circuit. Heating power and control accuracy up to 180 degrees Celsius The heating temperature range extends from room temperature to 180 degrees Celsius, set with a rotary knob with a setting accuracy of 1 Kelvin and read on an LCD display. With 3 litres of water at 90 degrees Celsius, the controller fluctuation is ±1 Kelvin and the absolute deviation from the mean value is ±2 Kelvin. With 3 litres of silicone oil (50 mPas) at 150 degrees Celsius, the controller fluctuation is ±2 Kelvin and the absolute deviation is ±4 Kelvin. This separate statement for water and oil shows that the control accuracy varies depending on the medium and the target temperature, an aspect that is relevant when choosing the temperature control medium for precision-critical applications. Open bath without external circulation, but compact and robust Unlike a circulating thermostat, the HB digital has no pump for the external connection of further devices. It is designed as an open bath for the direct heating of vessels in the bath itself. The inner diameter of the bath vessel is 225 millimetres with an inner height of 130 millimetres, and the minimum filling level is 60 millimetres. A fixed safety circuit at 190 degrees Celsius and an additionally adjustable safety circuit between 50 and 190 degrees Celsius protect against unintentional overheating, in line with the classification according to DIN 12876 Class II. Heating bath, heating bath circulator or heating and cooling unit: choosing the right design Anyone who needs only an open bath without an external connection is well served by the HB digital. If the same warm water bath is also to supply externally connected vessels or double-jacketed reactors, the IKA HBC 5 basic and the IKA HBC 10 control as heating bath circulators offer an integrated circulation pump for exactly this purpose. If active cooling is also required in addition to heating, for example for temperature cycles below room temperature, the IKA RC 2 lite as a pure recirculating chiller or the IKA HRC 2 lite as a combined heating and cooling unit is the more suitable choice. Typical applications As a compact heating bath with a stainless steel vessel and a temperature range up to 180 degrees Celsius, the HB digital is suitable for the following, among other uses: Heating and temperature control of samples in water or oil baths, for example during extractions or evaporation processes Viscosity measurements and other applications with temperature-dependent material properties at elevated temperature Heating reaction vessels or flasks that are suspended directly in the open bath Installation, operation and ongoing use It is operated via a rotary knob with LCD display, and a USB interface (Micro-USB) allows connection to a PC or software for logging temperature curves. The housing dimensions are 330 x 190 x 325 millimetres and the weight is 3.9 kilograms. The outer diameter of the bath vessel is 257 millimetres. The power consumption is 1450 watts in operation and only 3 watts in standby. The permissible ambient temperature range is 5 to 40 degrees Celsius at a maximum of 80 percent relative humidity, and the housing is protected to IP 21 according to DIN EN 60529. Care of the stainless steel bath vessel The vessel made of stainless steel 1.4404 that comes into contact with the product is corrosion-resistant to the usual temperature control media, water and silicone oil, and is easy to clean after cooling down. Before filling, it is advisable to note the minimum filling level of 60 millimetres, as with too low a level the safety circuit may trigger early or temperature stability may suffer. After prolonged operation with oil as the temperature control medium, the bath vessel should be cleaned thoroughly before changing the medium, to avoid carry-over between the media. Why the choice of temperature control medium affects accuracy When making the investment decision, it is worth considering the planned temperature control medium: for applications with water up to around 90 degrees Celsius, the absolute deviation of ±2 Kelvin is within a narrower range than with higher-viscosity oil baths at 150 degrees Celsius with ±4 Kelvin. Anyone who regularly works in the upper temperature range with oil and needs tighter control accuracy should check these values against the requirements of their own method before deciding on a standard heating bath. For most routine applications up to 180 degrees Celsius, however, the accuracy of the HB digital is sufficient, without the need for a more expensive equipment level with a circulation pump. Regarding the filling quantity: the closer the bath is operated to the maximum filling volume of 4 litres, the longer it takes at a constant heating power of 1400 watts for the bath to reach the target temperature, an aspect that affects throughput time in everyday laboratory work when set temperatures change frequently.

LAUDA Alpha RA 8 Cooling Bath, -25 to 100 °C, 5 to 7.5-litre Bath, L004603
Anyone who needs to maintain precise temperatures for small volumes in the laboratory, for example, when calibrating a viscometer, cooling a cuvette in analytical chemistry, or operating a small external reactor, requires a bath that can quickly reach sub-zero temperatures and takes up little floor space. With its 5.0 to 7.5-litre stainless steel bath, the LAUDA Alpha RA 8 caters precisely to this market segment. The operating temperature range extends from -25 to 100 °C, with cooling provided by a built-in compressor using the natural refrigerant R-290.Compressor cooling with automatic controlThe RA 8 actively cools via a built-in compressor; there is no need for an external cooling water connection or an additional circulation cooler. An automatic compressor control system switches the compressor on and off as required, which extends its service life and reduces energy consumption during continuous operation. The unit dissipates heat into the ambient air via an air-cooled condenser.Cooling capacity across the operating rangeWith ethanol as the bath medium, the RA 8 delivers a cooling capacity of 0.325 kW at 20 °C, 0.26 kW at 0 °C, at -20 °C it is still 0.1 kW, and at the lower limit of -25 °C it is 0.07 kW. The maximum heating power is 1.5 kW, the total power consumption is a maximum of 1.8 kW, and the current draw is 8 A. LAUDA specifies the temperature stability as ± 0.05 K; a 1-line LED display and a fully electronic, continuous controller handle the display and control functions.Circulation pump for external loadsA bath lid, a pump connection set and a short-circuit hose are supplied as standard. The built-in circulation pump delivers up to 15 L/min at a maximum pressure of 0.2 bar and can therefore also be used for small external loads such as a double-jacketed reactor or a cold trap. A drain connection on the rear facilitates the replacement of the bath medium.Safety during continuous operationLow-level protection and over-temperature protection monitor operation; in the event of deviations, the unit triggers an audible and visual alarm. The stainless steel bath vessel, with internal dimensions of 165 x 177 x 160 mm, is suitable for small batches of samples; the entire unit weighs 29 kg and measures 235 x 500 x 605 mm (W x D x H).Typical applicationsCalibration and testing of viscometers at defined sub-zero temperaturesTemperature control of cuvettes and small sample vessels in analytical applicationsCooling of small external reactors or double-jacketed vessels via the circulation pumpTraining and routine operation where only a small bath volume is requiredSelection guide within the Alpha seriesIf the bath volume of the RA 8 is insufficient for several vessels or a larger external load, the LAUDA Alpha RA 12 (9.5 to 14.5 l) and the LAUDA Alpha RA 24 (14 to 22 l) are available as two larger sister models with the same operating temperature range. If no active cooling is required at all, the LAUDA Alpha A 6 heating thermostat meets the same temperature control requirements without a built-in compressor.Technical detailsOperating temperature range-25 to 100 °CAmbient temperature range5 to 40 °Ctemperature stability± 0.05 KBath volume min. / max.5.0 / 7.5 LBath dimensions (W x D x H)165 x 177 x 160 mmOverall dimensions (W x D x H)235 x 500 x 605 mmWeight29 kgMax. heating power1.5 kWCooling capacity at 20 °C (ethanol)0.325 kWCooling capacity at 0 °C (ethanol)0.26 kWCooling capacity at -20 °C (ethanol)0.1 kWCooling capacity at -25 °C (ethanol)0.07 kWMax. power consumption1.8 kWCurrent consumption8 APump flow rate, max.15 L/minMax. pump pressure0.2 barMains supply220 V; 60 Hz / 230 V; 50 HzMains plugMains cable with angled Schuko plug (CEE7/7)RefrigerantR-290 (natural refrigerant), 0.052 kgStandardDIN 12876Scope of deliveryLAUDA Alpha RA 8 cold bath thermostat with stainless steel bath vessel, order number L004603Bath lidPump connection setShort-circuit hose for pump connectionsMains cable with angled Schuko plug (CEE7/7)Operating instructions as a PDF downloadRegulatory informationThis device is an electrical appliance within the meaning of the German Electrical and Electronic Equipment Act (ElektroG).

LAUDA Hydro H 8 Water Bath, 25 to 100 °C, up to 7 L, Bath Dimensions 245 x 200 mm, L002901
Anyone who regularly needs to bring individual test tubes, small sample vessels or a single round-bottomed flask up to a specific temperature in the laboratory does not need a large water bath, but rather one that takes up little space and heats up quickly. With a bath volume of 3.8 to 7.0 l, the LAUDA Hydro H 8 is the most compact model in the Hydro series. The operating temperature range extends from 25 to 100 °C with a temperature stability of ± 0.1 K, making applications right up to the boiling point possible.Small bath, short heating timeThe bath opening measures 245 x 200 millimetres with a depth of 165 millimetres. The maximum heating power of 1 kilowatt is tailored to this bath size, ensuring the water reaches the required temperature quickly. For routines involving just a few vessels, such as thawing small samples, incubating individual tubes or temperature-controlling calibration solutions, the Hydro H 8 is the most economical choice within the range in terms of both purchase price and electricity consumption.Operation via TFT colour displayA TFT colour display shows both the actual and setpoint values simultaneously; the temperature display can be switched between °C and °F. Setpoints are adjusted in 0.1 °C increments via a membrane keypad with clear symbols; a 1-point temperature controller then maintains the temperature at a constant level. A timer set in hours and minutes allows three application-specific time functions to be programmed, enabling the bath to run unattended for a specified duration. In the event of low water level, over- or under-temperature, or in the event of a sensor failure or short circuit, the unit emits a visual and audible alarm; the trigger points for the temperature alarm can be set to a maximum of ± 10 K.Stainless steel inside and outThe bath body, cover frame, sieve base and heating element are made of stainless steel. The bath vessel has a drain tap, allowing the water to be drained without tilting the bath. The lid supplied is thermally insulated, double-walled and domed on the inside; condensation runs down the dome to the side rather than dripping back into the vessels.Handling in everyday laboratory useThe drain tap on the bath vessel means that changing the water in this small volume takes just a few minutes; a drain hose is not strictly necessary. As the bath holds only a small amount of water, it can also be operated using distilled water or a temperature-control fluid without the cost per fill being a significant factor. For workstations with a limited number of sockets, the standard rated voltage of 230 volts at 50 or 60 hertz is sufficient.Typical applicationsTemperature control of individual test tubes, sample tubes or small flasks in research and quality assuranceCalibration baths for thermometers and sensors in the low-volume rangeThawing and preheating small sample quantities in medical technologySecondary workstations and teaching laboratories with limited floor spaceSelection guide: which Hydro size is right for youIf the bath volume of the H 8 is insufficient for multiple vessels, the series offers four larger models. With the same bath depth but a significantly wider opening of 400 x 245 millimetres, the Hydro H 16 accommodates more vessels side by side. Those requiring additional depth for tall flasks will find it in the Hydro H 22, which offers a bath volume of up to 20.3 l. The Hydro H 24 is suitable for an even wider opening of 600 x 245 millimetres, allowing many vessels to be placed in a row. The largest model in the range, the Hydro H 41, has a capacity of up to 37.9 l and is suitable for large batches or particularly tall vessels.Technical detailsOperating temperature range25 to 100 °CAmbient temperature range10 to 40 °Ctemperature stability± 0.1 KMax. heating power1 kWBath dimensions (W x D x H)245 x 200 x 165 mmTank capacity (min./max.)3.8 / 7.0 LOverall dimensions (W x D x H)340 x 395 x 275 mmWeight (net)10 kgMains supply230 V, 50/60 HzMains plugMains cable with angled Schuko plug (CEE7/7)Scope of deliveryLAUDA Hydro H 8 water bath with drive and control unit, order number L002901Stainless steel lid, double-walled with an inner curveStainless steel sieve trayMains cable with angled Schuko plug (CEE7/7)Regulatory informationThis appliance is an electrical appliance within the meaning of the German Electrical and Electronic Equipment Act (ElektroG).

IKA RC 2 basic, Recirculating Cooler, 400 W Cooling Capacity, -20 °C, 0004171000
Not every laboratory cooling application requires the latest refrigerant; some require, above all, availability and a tried-and-tested, non-flammable refrigerant. The IKA RC 2 basic recirculating chiller delivers up to 400 watts of cooling capacity at 20 degrees Celsius and operates with the refrigerant R134a, which is classified in safety group A1 and is therefore non-flammable. This unit is a discontinued model and is offered from existing stock; it is available immediately, with no lead time. Cooling capacity from room temperature down to minus 20 degrees Celsius As expected, the cooling capacity of the RC 2 basic decreases as the target temperature falls: 400 watts at 20 degrees, 370 watts at 10 degrees, 320 watts at 0 degrees, 240 watts at minus 10 degrees and 130 watts at minus 20 degrees Celsius. The operating temperature range extends from minus 20 degrees Celsius to room temperature; with an external heater, the bath can also be operated at temperatures up to 80 degrees Celsius. Temperature is controlled via a PT100 sensor; temperature stability is ±0.1 Kelvin in accordance with DIN 12876. Refrigerant and availability Refrigerant R134a (HFC-134a), charge 230 g, corresponding to 0.33 tonnes of CO2 equivalent, GWP 1430, safety group A1 in accordance with DIN EN 378-1 (non-flammable). The RC 2 basic is a discontinued model: IKA ceased production on 31 July 2026, and only existing stock is available. Its successor is the IKA RC 2 GREEN basic, which uses the refrigerant R290 and, according to IKA, offers approximately double the cooling capacity. Anyone who requires the 400-watt cooling capacity of the RC 2 basic, and nothing more, will receive a unit with a spare parts guarantee of at least ten years according to IKA, available immediately from stock. Please contact us if you would like to compare both variants for your application. Circulating chiller, circulation bath or heating bath: the right design Within the IKA temperature control unit range, three different designs can be distinguished: pure circulation coolers, such as the RC 2 basic, are designed solely for cooling; cooling and heating circulation thermostats, such as the HRC-2 series, provide both cooling and heating in a single unit; and heating baths provide heating without an active cooling function. The following overview compares the cooling capacity at various target temperatures: ModelModel20 °C0 °C-20 °CRefrigerant RC 2 basic (this product)Circulating cooler400 W320 W130 WR134a RC 2 liteCirculating cooler400 W250 WNot specified (minimum -10 °C)R290 HRC 2 liteCirculating water bath400 W250 W100 W (at -10 °C)R290 RC 2 basic compared to RC 2 lite and the HRC-2 series With a minimum operating temperature of minus 20 degrees Celsius, the RC 2 basic covers the lowest operating temperature range of the recirculating chiller sizes in this power class currently available from us. If, on the other hand, you are looking for a unit using the R290 refrigerant, you will find this in the slightly more compact IKA RC 2 lite. If the same unit needs to provide active heating as well as cooling, the IKA HRC 2 lite is the right choice. Typical applications According to the manufacturer, the RC 2 basic is suitable as an external closed-circuit cooling source for, amongst other things, cooling external equipment such as: Laboratory reactors Calorimeters Incubation shakers Rotary evaporators, such as the IKA RV 10 digital V-C or the IKA RV 3 V-C Connection, installation and ongoing operation The integrated pressure/suction pump achieves a maximum flow rate of 18 l per minute at a maximum pump pressure of 0.3 bar on the pressure side and 0.2 bar on the suction side. The internal bath has a capacity of between 1.4 and 4.0 l. RS232 and USB interfaces are available for connection to a PC or process control system. The housing is protected to IP 21 in accordance with DIN EN 60529; it can be connected to either 230 or 115 volts at 50 or 60 hertz. Why now: End of production and selecting the correct cooling capacity IKA has discontinued production of the RC 2 basic with effect from 31 July 2026. Consequently, only existing stock is still available; further orders are no longer possible, and the current stock is the last batch available. When selecting the appropriate cooling capacity, the target temperature is the key factor: if a cooling bath at around 0 degrees Celsius is sufficient, 320 watts of cooling capacity is still available; it is only at minus 20 degrees Celsius that the capacity drops to 130 watts. For applications that regularly require temperatures below minus 10 degrees Celsius, the RC 2 basic, with its operating range extending down to minus 20 degrees Celsius, is one of the few options we stock in this performance class.

LAUDA Loop L 100 Thermoelectric Circulating Bath, +80 °C, L000027
LAUDA Loop L 100: A revolution in compact temperature control The LAUDA Loop L 100 (MPN L000027) marks a technological shift in the laboratory. Where loud, heavy compressor-based coolers once stood, this thermoelectric circulation thermostat now ensures precise temperatures. The unit is based on Peltier technology. This means it operates entirely without refrigerant or a compressor. For you as a user, this means: less noise, fewer vibrations, less maintenance and a drastic reduction in your environmental footprint. The Loop L 100 is specially designed for external temperature control applications requiring constant temperatures between +4 °C and +80 °C. Peltier technology: cooling and heating using electricity At the heart of the LAUDA Loop L 100 is the Peltier element. When an electrical voltage is applied, heat is transferred from one side to the other. This technology offers key advantages over conventional systems: Refrigerant-free: As no F-gases (fluorinated greenhouse gases) are used, the unit is not subject to strict environmental regulations or leak tests. It operates in a completely climate-friendly manner. Low vibration: As there is no compressor in operation, there is virtually no mechanical vibration. This makes the Loop L 100 the ideal choice for vibration-sensitive applications such as microscopy or optical measurement techniques. Compact design: The design is extremely space-saving. With a width of just 17.5 cm, the unit fits on any laboratory bench, no matter how full it is. Dual function: The system can both cool and heat. Simply switching the polarity is enough for the Loop to switch seamlessly between modes to maintain the target temperature precisely. Main area of application: External applications The LAUDA Loop L 100 is a circulation thermostat only. It does not have an open bath into which samples are immersed, but rather a small internal reservoir. Its strength lies in supplying external devices. Typical areas of application include: Refractometers & polarimetres: Here, a constant temperature (often 20 °C or 25 °C) is crucial for accurate measurement results. Electrophoresis: Dissipation of the heat generated during the process to protect the gels from overheating. Micro-reactors: Temperature control of chemical syntheses on a millilitre scale. Sample preparation: Maintaining a constant temperature for cuvette holders in spectroscopy. Performance and efficiency Despite its small size, the Loop L 100 delivers impressive performance figures. It offers a cooling capacity of up to 120 watts (at 20 °C), which is more than sufficient for most small laboratory instruments. The pump capacity, with a flow rate of 2.6 l/min and a pressure of 0.8 bar, is optimally designed to deliver fluid even through narrower tubing or heat exchangers. A key feature is its energy efficiency: the fan adjusts its speed according to the load. In partial-load operation, the unit is therefore whisper-quiet and consumes only a minimal amount of electricity. Thanks to the wide-range mains adaptor (100–240 V), the Loop L 100 can be used worldwide without the need to switch settings – ideal for research groups operating internationally. Ease of use: simplicity is key Operation of the LAUDA Loop L 100 is kept to the essentials. Just three buttons are needed to make all the settings. OLED display: The display is bright, high-contrast and exceptionally easy to read, even from oblique angles. It shows the actual and setpoint values as well as the operating status. Plug & Play: Quick-connect couplings (CPC connectors) on the inlet and outlet allow the hoses to be connected in a matter of seconds without spilling a drop. A hose set is often already prepared, so you can get started straight away. Interface: An RS 232 interface is integrated as standard to integrate the device into automated laboratory environments or to document process data. Maintenance and safety Where there is no refrigerant, none can escape. And where there is no compressor oil, none needs to be changed. The Loop L 100 is virtually maintenance-free. Only the air filter on the front should be cleared of dust from time to time – this can be done without tools thanks to a magnetic mount. Safety is ensured by over-temperature protection and low-level protection. As the fill volume is very small (only approx. 0.3 litres), handling the temperature-control fluid is also safe and cost-effective. With the LAUDA Loop L 100, you are choosing the future of laboratory temperature control: green, quiet, compact and precise.

IKA C-MAG HP 10 hotplate, with glass-ceramic work surface, 0003582000
Thermodynamic efficiency and material resistance The IKA C-MAG HP 10 is a high-performance heating system specially developed for the thermal treatment of large-volume media and aggressive chemical substances. With a heating power of 1500 W and a footprint of 260 x 260 mm, the unit enables significant thermal energy transfer. The monolithic glass-ceramic plate is characterised by excellent chemical inertness and high resistance to thermal cycling. The material’s low thermal expansion ensures a flat surface even at maximum operating temperatures, which minimises the thermal contact resistance to the vessel. Metrological precision and system reliability The thermal parameters are controlled via a digital display, which allows precise monitoring of the setpoints. To regulate the medium temperature, the C-MAG HP 10 features an integrated interface in accordance with DIN 12878, which enables the connection of external contact thermometers (e.g. ETS-D5). The safety architecture comprises a fixed safety circuit at 550 °C and a visual ‘Hot Top’ warning indicator. The latter acts as a preventive safety mechanism against thermal injuries by detecting residual heat in the plate even after the heating function has been deactivated, as long as the surface temperature remains above 50 °C. Technical details Thermodynamics & Heating Technology Heating power: 1500 W Heating temperature range: 50 to 500 °C Heating temperature setting accuracy: ± 10 K Fixed safety cut-off: 550 °C Heating rate (1 l H₂O in H15): 5 K/min Metrology & Control Engineering Display: Digital LCD (setpoint) Connection for external temperature sensor: DIN 12878 (e.g. PT 1000) Control accuracy with sensor: ± 3 K Residual heat indicator: Visual warning signal (Hot Top indicator) Material Properties & Mechanics Surface material: Glass-ceramic (vitroceramic) Cooktop surface dimensions: 260 x 260 mm Housing material: Cast aluminium / corrosion-resistant plastic Chamber structure & dimensions Dimensions (W x H x D): 300 x 105 x 415 mm Weight: 6 kg Permissible ambient temperature range: 5 to 40 °C Permissible relative humidity: 80% Protection class according to DIN EN 60529: IP 21 Voltage: 230 V (50/60 Hz) Power consumption: 1505 W Contents of delivery 1 x IKA C-MAG HP 10 hotplate 1 x mains cable 1 x operating instructions Important note: An external temperature sensor (e.g. PT 1000) for direct control of the medium temperature is not included as standard and must be configured separately. Customised requirements & accessories For precise thermodynamic control in the liquid phase, an external resistance thermometer (PT 1000) or an electronic contact thermometer (ETS-D series) must be connected via the DIN 12878 socket.

If you have been searching for the IKA RC 2 basic recirculating chiller and have been redirected here: the previous model was discontinued on 31 July 2026; the IKA RC 2 GREEN basic recirculating chiller is the successor model designated by IKA. It delivers up to 800 watts of cooling capacity at 20 degrees Celsius and uses the natural refrigerant R290 instead of the previous R134a. As an external, closed-circuit cooling source, it cools rotary evaporators, laboratory reactors and other equipment with heat exchangers, regardless of the season or water pressure in the laboratory. Successor to the IKA RC 2 basic: what’s changing IKA has discontinued production of the RC 2 basic as of 31 July 2026 as part of the portfolio transition to natural refrigerants. IKA guarantees the availability of spare parts and repair services for all discontinued units in this series for at least 10 years. The RC 2 GREEN basic retains the design and connection dimensions virtually unchanged and is the direct successor. Compared with its predecessor, the refrigerant, cooling capacity and pump capacity have changed; in terms of temperature stability, the specified value for the successor is numerically higher than that of its predecessor. The following table compares both series with their respective documented values: FeatureRC 2 basic (predecessor)RC 2 GREEN basic (this product) RefrigerantR134aR290 Cooling capacity at 20 °C400 W800 W Max. pump pressure0.3 bar0.5 bar Max. flow rate18 l/min21 l/min Temperature stability (DIN 12876)±0.1 K±0.15 K Weight28.0 kg25.5 kg The RC 2 basic can still be used by existing customers; there is no ban on its operation and no expiry date for its use. Anyone still requiring a unit with the non-flammable refrigerant R134a will find the IKA RC 2 basic (item no. 0004171000) to be a suitable alternative from our remaining stock. Cooling capacity from room temperature down to minus 30 degrees Celsius As expected, the cooling capacity of the RC 2 GREEN basic decreases as the target temperature falls: 800 watts at 20 degrees Celsius, 700 watts at 10 degrees, 500 watts at 0 degrees, 400 watts at minus 10 degrees, 200 watts at minus 20 degrees and 90 watts at minus 30 degrees Celsius. The operating temperature range thus extends from minus 30 degrees Celsius to room temperature; with an external heater, the bath can also be operated at temperatures up to 70 degrees Celsius. Control is via a PT100 sensor with an LED display; the display resolution and setting accuracy of the setpoint temperature are both 0.1 Kelvin. R290 refrigerant: Safety group A3 and installation instructions The RC 2 GREEN basic operates with 69 grams of the natural refrigerant R290 (propane) at a maximum permissible pressure of 21 bar. According to DIN EN 378-1, R290 is classified as safety group A3 and is therefore flammable. According to the operating instructions, a minimum room volume of 9 cubic metres and a clearance of at least 20 centimetres in front of and behind the unit are required for safe operation: These values ensure that, even if the entire refrigerant charge were to escape, no flammable refrigerant-air mixture can form (R290: max. 8 g per cubic metre of room air). Practical note: As is standard for laboratory equipment using flammable refrigerants, it is recommended that the unit be installed in a well-ventilated area with no open ignition sources in the immediate vicinity. Display, warning functions and calibration The RC 2 GREEN basic displays the operating and safety temperatures on an LED display and features visual and audible warning functions in the event of overheating, as well as low- and high-level protection for the bath vessel. The internal temperature measurement can be calibrated. DIN 12876 specifies a temperature stability of ±0.15 Kelvin; the comparative value for the predecessor model can be found in the table in the section on the successor model above. Selection guide: RC 2 GREEN basic or RC 2 GREEN control The RC 2 GREEN basic and RC 2 GREEN control share the same refrigeration circuit, cooling capacity and pump, but differ in terms of control and operation: FeatureRC 2 GREEN basic (this product)RC 2 GREEN control Cooling capacity at 20 °C800 W800 W Temperature controlPT100 sensor, LED displayPID controller, TFT display Display resolution0.1 K0.01 K External PT100 connection (LEMO)NoYes WiCo wireless controller with programmesNoyes Weight25.5 kg26.5 kg If you only need to read and set the target temperature directly on the unit, the RC 2 GREEN basic is the right choice for you. If you also wish to connect an external temperature probe, programme temperature profiles or monitor the unit wirelessly, the IKA RC 2 GREEN control is the model for you. Positioning within the IKA recirculating chiller range Within the IKA temperature control unit range, the RC 2 GREEN basic sits between two neighbouring series. Those looking for a more compact entry-level solution with lower cooling capacity will find what they need in the IKA RC 2 lite, which delivers up to 400 watts at 20 degrees Celsius and operates down to minus 10 degrees Celsius. Those who need to actively heat as well as cool will find what they are looking for in the IKA HRC 2 GREEN basic or, with an additional WiCo wireless controller, in the IKA HRC 2 GREEN control; both are identical in design to the RC 2 GREEN series but feature an additional heating function. Typical applications As an external closed-circuit cooling source, the RC 2 GREEN basic is suitable for, amongst other things: Cooling rotary evaporators, such as the IKA RV 10 digital V-C or the IKA RV 3 V-C Cooling reflux condensers during syntheses and extractions As a cooling source for laboratory reactors, double-walled vessels and other equipment with heat exchangers Applications with higher cooling requirements due to higher solvent flow rates or lower target temperatures than with the RC 2 lite Connection, installation and ongoing operation The integrated pressure/suction pump achieves a maximum flow rate of 21 l per minute at a maximum pump pressure of 0.5 bar on the pressure side and 0.25 bar on the suction side, connected via M16x1 threaded connections. The internal bath has a capacity of between 1.4 and 4.0 l. RS232 and Micro-USB interfaces are available for connection to a PC or process control system. The permissible ambient temperature range is 5 to 32 degrees Celsius with a maximum relative humidity of 80 per cent; the housing is protected to IP 21 in accordance with DIN EN 60529.

IKA IB R 20 eco plastic bath for thermostats, polycarbonate, 20 litres, 0020004383
The IKA IB R 20 eco plastic bath is a structurally stable, high-capacity, materials-science-based system solution for the professional temperature control of larger sample volumes in clinical, chemical and biological laboratory environments. Specially developed as a perfectly matched system component for IKA immersion thermostats (such as the universal ICC or Bridge series), this high-quality temperature-controlled vessel, with a capacity of 20 litres, provides the ideal basis for safe and reproducible water bath applications on a larger scale. For precise thermodynamic processes in everyday laboratory work, structural durability and excellent thermal insulation are the primary criteria for ensuring constant temperature control throughout long-term test series in a way that is gentle on materials and reliable for the process. Material robustness and complete process visibility The material design of the IB R 20 eco is based on a high-quality, transparent polycarbonate (PC). This specialised plastic is characterised by outstanding impact strength, mechanical resilience and excellent dimensional stability at temperatures of up to 100 degrees Celsius. The crystal-clear optical properties of the bath material offer the user a decisive advantage in day-to-day laboratory use: they allow continuous and unrestricted visual monitoring of all sample vessels (such as test tubes, flasks or reactors) within the bath at any stage of the temperature control process, without the need to disrupt the thermal equilibrium by opening a lid. Generous capacity and optimised thermodynamics From a thermodynamic perspective, the wall thicknesses and geometry of the bath have been optimised to minimise heat loss to the surroundings, even with a large volume of 20 litres. This energy efficiency significantly reduces the load on the attached thermostat and helps to lower the overall carbon footprint of laboratory operations whilst minimising material consumption. To ensure safe fluid management and optimal ergonomic handling, the plastic bath features integrated, ergonomically shaped carrying handles on the front sides. These enable laboratory staff to move, transport or empty the bath in complete safety, even when it is filled with warm temperature-controlled medium. Seamless system integration and rigorous GLP compliance The bath’s structural design guarantees a perfect fit when installing the heating components. The interaction with the original IKA bath bridges ensures that the suspended thermostat is fixed in place absolutely wobble-free and securely. This reliably prevents uncontrolled vibrations or the heating unit from slipping during continuous operation. The easy-to-clean, non-porous surface of the polycarbonate also prevents the build-up of germs or algae residues, enabling the IB R 20 eco to meet the highest standards for clean workplaces in accordance with stringent GLP guidelines.

Individual requirements & accessories To complete your temperature control system, we recommend operating the IKA IB R 20 eco with an original IKA immersion thermostat from the ICC eco or ICC control series. To effectively minimise water evaporation losses at operating temperatures above 60 degrees Celsius, we stock suitable polycarbonate bath lids and floating insulating balls. For the organised placement of your sample vessels, we also offer corrosion-free test tube holders, stainless steel inserts and additional cooling coils for external cooling media. Please make use of our technical procurement service to ensure your thermostat peripherals are correctly matched.
Memmert water bath WTB35, 32 L, touch display, +100 degrees Celsius
Pre-order: The Memmert water bath WTB35 belongs to Memmert's new water bath generation. You can pre-order it from us now, deliveries start in January 2027. The Memmert water bath WTB35 tempers larger sample volumes between +10 and +100 degrees Celsius. At 32 litres, it fits several racks or larger vessels at once. New model generation The WTB35 is part of the full relaunch of the Memmert water bath range for price list 01-2027, which replaces the previous model line entirely. Accessories such as lids, base grids, insert racks and test tube racks now come with new order numbers. The pump module P7 for circulating the water bath can now be ordered as a factory option, previously the circulation pump was a separate retrofit part. When reordering accessories, it is worth checking the current order number, listed further down in this description. Touch display and controls A 3.5-inch colour graphic touch display with 2-point calibration controls the temperature to an accuracy of 0.1 degrees Celsius. The customisable remote screen “CustomView” allows its own display layout, useful when several identical units run in the same lab. The display shows the key operating values at a glance, no separate control panel is needed. Stainless steel tank and cleaning The deep-drawn stainless steel tank (1.4301) is made without corners or edges, the integrated central drain system makes emptying easier given the larger fill volume here. The heater sits outside the chamber, the housing is stainless steel, four adjustable feet carry the extra weight safely. That makes daily cleaning and disinfection between two different batches easier. Connection and operation Power draw is 2,840 watts at 230 V and 1,840 watts at 115 V (50/60 Hz). The 115 V version is available as option X2 (order number WTB6X2) at no extra cost. A standard lab socket is enough, no dedicated high-current connection is needed. Size within the WTB range At 32 litres, the WTB35 is the second-largest model, between the WTB24 and the WTB50. Controls, material and drain system are identical across the whole range, what mainly differs is internal dimensions, capacity, weight and, from the WTB15 upward, whether the pump module P7 is available. Footprint and transport Internal dimensions are 650 x 140 x 450 mm, external with the flat lid 747 x 547 x 292 mm, with the sloped lid 747 x 547 x 404 mm. Packed, the WTB35 arrives in a box measuring 840 x 680 x 495 mm, gross weight 37.5 kg, net weight 32.5 kg. Given the weight, moving it into the lab is easier with two people. Pump module P7 For the WTB35, the pump module P7 can be ordered as a factory option (824 euros net) and handles continuous circulation of the tempering medium, useful at larger fill volumes and dense loading. Without P7, the water surface stays calm, for example for gently thawing sensitive samples. Calibration and documentation A factory calibration certificate is not part of the standard equipment and is not included in the scope of delivery. Anyone who needs documented calibration, for example for a quality management system under ISO 9001 or for test equipment monitoring, can order it as an additional chargeable service through our procurement service. That way the initial commissioning can be documented without having to ship the unit off separately. Typical applications With a setting range of +10 to +100 degrees Celsius, the WTB35 covers a wide range of tempering tasks in the lab. With several test tube racks or the basket insert, larger sample series can be processed in a single run. Tempering larger sample volumes or several racks at onceThawing and warming processes where the pump module helps even out the temperature distributionFood and water analysis with higher sample throughputChemical and microbiological routine work that needs documented temperature control For larger sample volumes or several racks at once, the WTB35 is a good fit, with the pump module P7 available for even mixing. Anyone who needs still more capacity will find the WTB50 as the largest model in the range. Manufacturer's WEEE registration number (Memmert GmbH + Co. KG, Stiftung EAR): DE 66812464. Memmert units bought from us are covered for three years from delivery: the first 12 months are followed by a 24-month warranty under Memmert's terms, handled through us.
