Promotional items from the IKA Specials Q4/2026, valid until 31 December 2026. The crossed-out price is IKA’s recommended retail price. Our promotional price is net.The IKA RCT basic anodized magnetic stirrer with heating (MPN 0020133785) expands the RCT series to include a variant with an anodized aluminium base. With a heating power of 800 watts, a maximum stirring capacity of up to 20 litres of water and a closed housing with degree of protection IP 54, the unit is suitable for laboratory applications requiring rapid, direct heat transfer without thick barrier layers, such as demanding chemical reactions, syntheses and thermal processes in industrial and academic laboratory settings. Maximum thermal conductivity thanks to the anodized base The key design feature of this model is the circular base with a diameter of 135 millimetres, made from anodized aluminium. Unlike traditional ceramic coatings, the anodized metal surface offers high, direct thermal conductivity. This reduces heating times in day-to-day laboratory work, as energy is transferred to the vessel with minimal loss. The anodized layer protects the underlying aluminium from mechanical abrasion, scratches and a wide range of solvents. This ensures a long service life and consistent performance in day-to-day routine use. Precise kinetics and temperature control The control electronics of the RCT basic anodized allow for stepless adjustment of the stirring speed from 50 to 1,500 revolutions per minute, set via a rotary-push control with a setting accuracy of 10 revolutions per minute. The LED display shows setpoint and actual values for speed and temperature at all times. For temperature-sensitive media, a connection socket is provided for external PT1000 series temperature sensors as well as for the ETS-D5 and ETS-D7 contact thermometers. With the PT1000 or ETS-D5, the temperature of the medium can be controlled with an accuracy of ±0.5 Kelvin; with the ETS-D7 or the PT wireless probe, this improves to ±0.2 Kelvin. The ETS-D7 or PT wireless can also be used to measure the pH value of the medium as an optional feature. Robust housing and safety concept The system architecture is housed in a robust, closed die-cast aluminium housing with degree of protection IP 54. This sealing reliably protects the motor and control boards from splashing water and aggressive vapours during continuous operation. An independently adjustable safety circuit (50 to 360 °C) monitors the maximum temperature of the heating plate and switches off the heating in the event of an unexpected overheating. In addition, a visual residual heat indicator warns staff of the risk of burns until the surface has cooled down again. For the first time, the RCT basic anodized features an integrated menu function with a timer: the freely programmable timer can be set to start either immediately or only once the target temperature has been reached, and emits an audible signal when the time has elapsed; it is possible to specify separately whether the heating and/or stirring should switch off afterwards. With dimensions of 160 x 100 x 200 millimetres (W x H x D) and a net weight of 2.3 kilograms, the unit remains compact enough to operate several units side by side in a fume hood. Typical applications The anodized base and the connection options for external temperature sensors make the RCT basic anodized a versatile stirrer for various laboratory applications in research and industrial quality control: Chemical syntheses and reactions with rapid, direct heat transfer via the anodized aluminium plate Homogenisation and heating of larger volumes of up to 20 litres of water Precise temperature control within the medium using a PT1000, ETS-D5, ETS-D7 or the PT wireless probe Routine processes in quality control and research where short heating times of up to 9 Kelvin per minute are required Continuous use in the laboratory thanks to IP 54 protection against splashing water and vapours Technical details Number of stirring points1 Max. stirring capacity (based on water)20 litres Maximum load25 kg Motor typeBrushless DC motor (EC), 9 W output power Speed range50 to 1,500 rpm Speed controlContinuously variable via rotary push-button control Setting accuracy for speed10 rpm Stir bar length20 to 80 mm Heating power800 W Heating plate temperatureRoom temperature to 310 °C Temperature setting resolution1 K (heating plate), 0.1 K (actual value display) Safety temperature range (adjustable)50 to 360 °C Heating rate (1 l H₂O, heating stage H1500)9 K/min Control accuracy with PT1000±0.5 K Control accuracy with ETS-D5±0.5 K Control accuracy with ETS-D7 or PT wireless±0.2 K Control accuracy at the centre of the heating plate without a vessel (at 100 °C)±5 K Self-heating of the hotplate (ambient temperature 22 °C, 1 hour of stirring)max. +12 K Material of the base plateAnodised aluminium (aluminium oxide coating) Dimensions of the base plateØ 135 mm Overall dimensions (W x H x D)160 x 100 x 200 mm Net weight2.3 kg Degree of protection according to DIN EN 60529IP 54 DisplayLED display for setpoint and actual values Connection for external temperature sensorPT1000 series, ETS-D5, ETS-D7, PT wireless Timer1 second to 5,999 minutes Digital interfacesRS232 and USB-C WPAN interfaceoptional via USB-WD dongle pH measurementOptional with ETS-D7 or PT wireless Power consumption820 W, standby 0.45 W Mains connection220 to 230 V, 50/60 Hz Scope of delivery 1 x IKA RCT basic anodized magnetic stirrer with heating (MPN 0020133785) 1 x mains cable 1 x Detailed operating instructions / safety guide Compatible accessories The following original accessories are available to expand the functionality of the RCT basic anodized: IKA PT1000.60 stainless steel temperature probe for direct control within the medium, combined with the H 16 V support rod and the H 44 boss head for securing to the stirrer Precisely fitting silicone protective cover (H 104) to protect the control panel from splashes IKA Dry attachments (DryZone) made of anodized aluminium for oil-free heating of round-bottom flasks PTFE-coated magnetic stir bars in cylindrical, oval or triangular shapes Individual requirements and procurement service The IKA manufacturer’s warranty applies to the RCT basic anodized: 2 years, extended to 10 years upon registration at ika.com/register within 90 days of purchase.

Promotional items from the IKA Specials Q4/2026, valid until 31 December 2026. The price shown with a line through it is IKA’s recommended retail price. Our promotional price is net.The IKA RET basic anodized magnetic stirrer with heating (MPN 0020133787) combines a heating power of 800 watts with a compact housing measuring 160 x 200 x 100 millimetres and integrated Wi-Fi and LAN interfaces. This allows the unit to be used in a confined space within a fume hood or on a laboratory lift platform, whilst simultaneously integrating it into networked laboratory infrastructures. For B2B laboratory set-ups with high safety and documentation requirements, the RET basic anodized offers a combination of rapid heating, precise speed control and a comprehensive, standards-compliant safety concept for continuous daily use. Compact design with high power density and anodized protection The 135-millimetre base consists of a highly thermally conductive aluminium substrate and enables heating rates of up to 9 Kelvin per minute with uniform temperature distribution, adjustable across four heating speed settings. To protect against mechanical wear, scratches and aggressive chemical reagents, the surface is sealed with an anodized coating. Despite the high heating power of 800 watts, the housing remains ultra-compact at 160 x 200 x 100 millimetres. The stirrer therefore saves space in the fume hood, can be positioned on any standard laboratory lifting platform and is suitable for parallel experimental set-ups in confined spaces. Networked laboratory processes via Wi-Fi and LAN For integration into networked laboratory infrastructures and automated documentation processes, the RET basic anodized is equipped as standard with Wi-Fi and LAN interfaces, as well as the wired USB-C and RS232 interfaces. This connectivity allows the magnetic stirrer to be monitored centrally, controlled remotely or integrated into higher-level software solutions, including via the IKA app. The communication interface, which is based on ASCII-based Namur commands, also enables direct device-to-device communication. For example, the RET basic anodized can be linked to an IKA overhead stirrer: if the stirring speed of the viscous medium falls below a critical threshold, the RET basic anodized automatically deactivates the heating. This is an important prerequisite for reliable, unattended continuous operation. Comprehensive safety concept in accordance with EN IEC 61010-2-010 With a total of 18 integrated safety features, the RET basic anodized complies with the laboratory equipment standard EN IEC 61010-2-010 for heated laboratory equipment. System safety is further confirmed by a certificate from TÜV Süd in accordance with the NRTL standard (comparable to UL and CSA). In addition to a mechanically adjustable safety circuit (50 to 360 °C) via two separate plate sensors, the unit features Delta-T medium monitoring, sensor breakage and misalignment detection, as well as automatic heating shutdown in the event of a sudden drop in temperature, such as that caused by glass breakage. In the event of a safety shutdown, the ‘Always-Stir’ function takes effect: heating is stopped whilst stirring remains active to prevent delayed boiling or hotspots in the medium. An optical residual heat warning also protects against burns on surfaces exceeding 50 °C. Typical applications The combination of network connectivity, compact design and comprehensive safety features makes the RET basic anodized a versatile instrument for digitised laboratory environments: Networked laboratory processes requiring documentation, thanks to integrated Wi-Fi and LAN interfaces Unattended continuous operation through coupling with an IKA overhead stirrer via Namur commands Demanding syntheses with high safety requirements thanks to 18 safety features in accordance with EN IEC 61010-2-010 Mobile process monitoring via the IKA app Suitable for use in fume hoods and on laboratory lifting platforms thanks to its compact housing dimensions of 160 x 200 x 100 millimetres Technical details Number of stirring points1 Max. stirring capacity (based on water)20 litres Motor typeBrushless EC motor Speed range50 to 1,700 rpm Heating power800 W Heating plate temperatureRoom temperature to 340 °C Maximum heating rateup to 9 K/min Heating speed4 levels, individually adjustable Base diameter135 mm Base materialAluminium with anodized finish Network interfacesWi-Fi and LAN Data interfaces (wired)USB-C and RS232 Communication standardASCII-based Namur commands App integrationIKA APP Compliance with standardsEN IEC 61010-2-010, TÜV Süd NRTL-tested (UL/CSA standard) Number of safety features18 Adjustable safety circuit50 to 360 °C Safety function: mediumDelta-T monitoring Delayed boiling protectionAlways-Stir function Burn protectionVisual residual heat warning from a surface temperature of over 50 °C Display technology14-segment glass display Housing materialDie-cast aluminium housing, sealed Degree of protection according to DIN EN 60529IP 54 Dimensions (W x D x H)160 x 200 x 100 mm Country of originMade in Germany Scope of delivery1 x IKA RET basic anodized magnetic stirrer with heating (MPN 0020133787)1 x PT 1000.60 temperature sensor, stainless steel1 x H 801 x IKAFLON 30 magnetic stir bar1 x IKAFLON 40 magnetic stir bar1 x screwdriver1 x mains lead1 x operating instructions Compatible accessories The following original accessories are available to upgrade the RET basic anodized to a fully-fledged laboratory measuring station: IKA Pt.Wireless wireless temperature sensor or ETS-D7 contact thermometer for wireless temperature monitoring Chemically resistant IKA synthesis blocks and dry attachments made from anodized aluminium for oil-free heating of round-bottom flasks Precisely fitting silicone protective covers, as well as H 16 V support rods and H 44 boss heads for securing wired sensors Individual requirements and procurement service Our procurement service is available to assist with the digitalisation planning of your laboratory processes, as well as for further original accessories, spare parts or bespoke calibration.

Promotional item from the IKA Specials Q4/2026, valid until 31 December 2026. The crossed-out price is IKA's non-binding recommended retail price. Our promotional price is net.The IKA RCT basic magnetic stirrer with heating (MPN 0025008259) is a magnetic stirrer with heating for stirring and heating in everyday laboratory work. The current generation covers the full range of typical laboratory tasks, from preparing small reagent quantities to stirring larger volumes, with a stirring capacity of up to 20 litres of water, a heating power of 800 watts and a speed range of 50 to 1,500 revolutions per minute. The 135 mm aluminium base plate gives even heat distribution, and the IP 54 degree of protection keeps the unit safe from splashing water during continuous use. Powerful drive and precise speed control The magnetic drive of the RCT basic covers a stepless speed range from 50 to 1,500 revolutions per minute, set via a rotary push button control with a setting accuracy of 10 rpm. Stir bars from 20 to 80 mm in length can be used, so the unit suits small beakers as well as larger vessels with a load of up to 25 kg. The drive is a brushless DC motor with 9 watts of output power and keeps a constant speed even at higher viscosities, without a noticeable change in the stirring pattern as the load increases. With the optional IKA HUB, automatic reverse rotation and intermittent operation can also be activated, for example to loosen deposits on the stir bar or to automate recurring stirring cycles. Aluminium base plate and glass control panel The base plate of the RCT basic is made from an aluminium alloy with a diameter of 135 mm and gives fast, even heat transfer during heating. The control panel with its glass surface is easy to clean even with frequent contact with chemicals. The housing is protected to IP 54 against splashing water and dust, a clear step up from the IP 42 rating of the previous generation, and can therefore also be used at workstations where splashing water may occur. Heating power and safety concept for continuous operation With a heating power of 800 watts, the RCT basic heats one litre of water by 9 kelvin per minute in heating stage H1500, noticeably faster than the 600 watts and 6.5 kelvin per minute of the previous generation, and reaches temperatures from room temperature up to 310 °C, adjustable in steps of 1 kelvin. The safety temperature range can be set independently between 50 and 360 °C with a tolerance of 5 °C and switches off the heater immediately on an unexpected overtemperature. If the unit is switched off while the heating plate is still above 50 °C, the display alternates between the warning "HOT" and the current plate temperature until the plate has cooled to a safe level. Combined with the supplied external PT1000 temperature sensor, control accuracy in the medium reaches ±0.5 kelvin; with an optional IKA ETS-D5 contact thermometer it stays at ±0.5 kelvin, and with the ETS-D7 or the wireless PT wireless sensor it improves to ±0.2 kelvin. The ETS-D7 or PT wireless sensor also allows an optional pH reading of the medium on the RCT basic. Digital display and interfaces for process documentation An LED display shows setpoint and actual values for speed and temperature in real time, so the process can be monitored at all times. Via the digital USB-C and RS232 interfaces, the RCT basic can be connected to a PC and documented, for example, with the labworldsoft laboratory software. For external temperature measurement, a socket is available for the PT1000 series as well as the ETS-D5 and ETS-D7 electronic contact thermometers, and an optional USB-WD dongle also connects the wireless PT wireless sensor via WPAN. A built-in timer covers times from 1 second to 5,999 minutes, and a sensor-in-medium detection reports once the temperature probe is actually immersed in the medium. When the RCT basic is controlled externally via IKA HUB or labworldsoft, the device controls can be locked with the safeSTOP function, and the display then shows "safeSTOP". Power supply is 220 to 230 volts at 50 or 60 hertz, with power consumption of 820 watts in operation and 0.45 watts in standby. Compact format for parallel use At 160 x 100 x 200 mm (width x height x depth) and a net weight of 2.3 kg, the RCT basic takes up little space on the bench or in the fume hood. Its compact format makes it easier to run several units in parallel, for example when quality control or research work needs several batches stirred and heated at the same time. Because the stirrer and the heater are combined in one unit, there is no need to set up separate stirring and heating devices, which saves bench space and reduces cabling at the workstation. Typical applications As a base unit for stirring and heating liquid media, the RCT basic is used across a wide range of laboratory settings, from routine analysis to synthesis: Preparing and heating buffers, nutrient solutions and reagents in the routine lab Chemical syntheses with defined temperature control, for example reflux boiling or dissolving solids Homogenising larger volumes of solution thanks to a stirring capacity of up to 20 litres of water, for example stock solutions in quality control Sample preparation with external temperature monitoring via PT1000, ETS-D5, ETS-D7 or PT wireless, for example during digestion or extraction Training and teaching in chemistry and pharmacy, where robust, easy-to-use instruments are needed Technical details Number of stirring positions1 Max. stirring volume per position (H2O)20 litres Maximum load25 kg Speed range50 to 1,500 rpm Speed adjustmentStepless via rotary push button Speed setting accuracy10 rpm Max. stir bar length20 to 80 mm Motor typeBrushless DC motor (EC), 9 W output Heating power800 W Heating temperature rangeRoom temperature to 310 °C Temperature setting resolution1 K (heating plate), 0.1 K (actual value display) Adjustable safety temperature range50 to 360 °C ± 5 °C Heating rate (1 l H2O, stage H1500)9 K/min Control accuracy with PT1000± 0.5 K Control accuracy with ETS-D5± 0.5 K Control accuracy with ETS-D7 or PT wireless± 0.2 K Control accuracy at heating plate centre without vessel (100 °C)± 5 K Self-heating of the base plate (RT 22 °C, 1 h stirring)max. + 12 K Base plate materialAluminium alloy Base plate dimensionsØ 135 mm Overall dimensions (W x H x D)160 x 100 x 200 mm Net weight2.3 kg Degree of protection per DIN EN 60529IP 54 DisplayLED display for setpoint and actual values Connection for external sensorPT1000 series, ETS-D5, ETS-D7, PT wireless Timer1 second to 5,999 minutes Digital interfacesRS232 and USB-C WPAN interfaceoptional via USB-WD dongle pH measurementoptional with ETS-D7 or PT wireless Safety systemsAdjustable safety circuit, HOT display warning, sensor-in-medium detection, safeSTOP function Power consumption820 W, standby 0.45 W Power supply220 to 230 V, 50/60 Hz Scope of delivery 1 x IKA RCT basic magnetic stirrer base unit (MPN 0025008259) 1 x IKA PT 1000.60 temperature sensor 1 x mains lead 1 x screwdriver for the safety circuit 1 set of IKAFLON 30 round and IKAFLON 40 round magnetic stir bars 1 x quick start guide 1 x warranty card Matching accessories The RCT basic has a socket for external PT1000 series temperature sensors as well as the ETS-D5 and ETS-D7 contact thermometers, so it can be upgraded in a targeted way: IKA ETS-D5 electronic contact thermometer with touchscreen (MPN 0025008371) for temperature control with an accuracy of ±0.5 kelvin in the medium Further original accessories such as the wireless PT wireless temperature sensor, the ETS-D7 or the USB-WD dongle for WPAN connection are available through our procurement service.

For B2B laboratory environments with high safety and documentation requirements, the RET basic combines a fast heating rate, precise speed control and a comprehensive, standards-compliant safety concept for continuous daily use. Compact design with high power density and direct heat transfer The 135-millimetre heating surface is made of an aluminium alloy without any additional coating, thereby enabling particularly direct heat transfer with heating rates of up to 9 Kelvin per minute whilst maintaining uniform temperature distribution; this can be adjusted across four heating speed settings. Unlike the RET basic anodized version, there is no additional oxide layer protection against scratches and chemicals; instead, the bare metal surface transfers heat without the low resistance of a coating. Despite the high heating power of 800 watts, the housing remains ultra-compact at 160 x 200 x 100 millimetres.

A glass flask is not very forgiving if, when boiling under reflux, a sensor cable rubs against the clamp or if an oil bath spills onto the hotplate should the flask break. The IKA RCT basic Synthesis Solution 250 (ID No. 0010016490) addresses both issues: a wireless temperature sensor measures directly within the reaction medium, a second, wired sensor simultaneously monitors the synthesis block, and the flask is housed in an aluminium block rather than in an open oil bath. IKA supplies the complete set for round-bottom flasks up to 250 millilitres: the RCT basic magnetic stirrer with heating, flask holder, PT wireless and PT1000 sensors, USB dongle, as well as a stand and clamps for securing the flask. Wireless temperature and pH measurement in the reaction medium The centrepiece of the set is the PT wireless sensor, which transmits measurement values wirelessly to the RCT basic. A pH electrode can also be connected via the PT wireless’s BNC socket; the RCT basic’s display then shows the pH value directly, without the need for a separate measuring device. As there is no longer a sensor cable leading to the flask, the setup on the stand remains more flexible, and there is no risk of cables being damaged or scorched by contact with the heating plate. The supplied USB WD dongle also connects the RCT basic wirelessly to the IKA Lab Assistant app for visualising the measurement data. Dual temperature monitoring for greater safety In addition to the PT wireless, the set includes the wired PT 1000.60 sensor. Both sensors measure simultaneously, but at different locations: the PT 1000.60 monitors and limits the temperature at the synthesis block or heat transfer medium, whilst the PT wireless measures the temperature directly within the reaction medium. The RCT basic displays both values side by side on the screen. This separate measurement is particularly important in the event of glass breakage, as a sudden discrepancy between the block temperature and the medium temperature becomes immediately apparent and does not have to be detected via a single measurement point. Synthesis block instead of an oil bath The flask holder supplied (IKA designation H 135.25, for 250 ml round-bottom flasks, without handle) is a synthesis block made of solid anodised aluminium and is temperature-resistant up to 300 °C. Compared to an oil or sand bath, this significantly reduces the potential for hazards and simplifies handling and cleaning, as there is no risk of an oil bath leaking or sand becoming stuck. A universal clamp (R 350) additionally secures the flask to the stand. The RCT basic has a second stand mount, which can be used to attach an additional stand rod for a reflux condenser if required. RCT basic as a basic unit: stirring and heating with 800 watts The basic unit covers a speed range of 50 to 1,500 revolutions per minute, adjusted via a rotary-push control with an accuracy of 10 revolutions per minute. Stir bars with lengths of 20 to 80 millimetres can be used; according to the data sheet, the stirring capacity is up to 20 litres of water, and the maximum load is 25 kilograms. The heater has an output of 800 watts and reaches temperatures ranging from room temperature to 310 °C; one litre of water heats up by 9 Kelvin per minute in heating stage H1500. The safety circuit can be set independently of the setpoint between 50 and 360 °C, a control logic that IKA has been using for decades in heated equipment. The die-cast aluminium housing is rated to IP 54, which protects against splashing water. Safety concept for unattended operation Beneath the heating plate are two further, separate temperature sensors: one controls the setpoint temperature, whilst the second monitors an independently adjustable safety limit in accordance with EN IEC 61010-2-010; this setting is adjusted mechanically directly on the unit and is independent of the process setpoint. If the medium temperature drops suddenly, for example due to glass breakage or the medium evaporating, the RCT basic detects this and can switch off the heating. If the temperature fails to rise despite the power supply, for example because a sensor is not immersed in the medium, the device also deactivates the heating automatically. A visual warning is also displayed as soon as the plate surface exceeds 50 °C, even if the unit is already switched off. Differences compared to the larger sets in the series The Synthesis Solution 250 shares the base unit with the 500 and 1,000 millilitre sets; the flask holder in all three sets is tailored to the respective flask volume. If you mainly run small batches up to 250 millilitres, this set will suffice. If your batches regularly reach 500 or 1,000 millilitres, the corresponding larger sets are the more obvious choice. Typical applications As a synthesis kit with wireless sensor technology, the RCT basic Synthesis Solution 250 is suitable for, amongst other things: Organic syntheses on a 250-ml scale with simultaneous monitoring of block and medium temperatures Refluxing, where an additional stand rod is required for the condenser pH monitoring directly in the reaction mixture, without a separate pH meter at the workstation Laboratory workstations that wish to avoid open oil baths for safety or cleaning reasons Technical details Number of stirring points1 Max. stirring volume (H₂O)20 l Maximum load25 kg Motor power output9 W, brushless DC motor Speed range50 to 1,500 rpm Speed adjustment accuracy10 rpm Stir bar length20 to 80 mm Heating power800 W Heating temperature rangeRoom temperature to 310 °C Heating rate (1 l H₂O, heating setting H1500)9 K/min Adjustable safety circuit50 to 360 °C Control accuracy with PT1000 (500 ml H₂O, 40 mm stir bar, 600 rpm, 50 °C)±0.5 K Set-up plate materialAluminium alloy, Ø 135 mm Degree of protection according to DIN EN 60529IP 54 InterfacesRS232, USB-C, USB WD dongle (wireless) Dimensions of base unit (W x H x D)160 x 100 x 200 mm Net weight of base unit2.3 kg Power supply220 to 230 V, 50/60 Hz Power consumption820 W Flask holder volume250 ml, without handle Flask holder materialAnodised aluminium, temperature-resistant up to 300 °C Wired temperature sensorPT 1000.60, stainless steel Wireless temperature sensorPT wireless, with BNC connector for optional pH electrode Scope of delivery 1 x IKA RCT basic magnetic stirrer with heating 1 x PT wireless, wireless temperature sensor 1 x H 16 V stand rod 1 x holding rod H 38 2 x H 44 boss heads 1 x H 80 holder for the temperature sensor 1 x R 350 universal clamp 1 x PT 1000.60 temperature sensor, stainless steel 1 x USB WD, USB dongle for the RCT basic 1 x flask holder H 135.25 for 250 ml round-bottom flasks, without handle 5 x IKAFLON 25 ellipse, magnetic stir bars 1 x IKAFLON 30 magnetic stir bar 1 x IKAFLON 40 magnetic stir bar 1 x screwdriver for assembly Individual requirements & procurement service Those who regularly carry out larger batches will find the IKA RCT basic Synthesis Solution 500 (MPN 0010016483) or the Synthesis Solution 1000 (MPN 0010016478) to be the suitable set for 500 or 1,000 millilitres respectively.

Promotional items from the IKA Specials Q4/2026, valid until 31 December 2026. The crossed-out price is IKA’s non-binding recommended retail price. Our promotional price is net.The IKA RH lite magnetic stirrer with heating is a cost-effective and efficient solution for the precise mixing, temperature control and homogenisation of liquids in biological, chemical and university laboratory environments. As a robust entry-level and routine instrument from IKA Laboratory Technology, this compact unit is designed for stirring tasks involving volumes of up to 15 litres of water. For everyday standard applications, reagent preparation or simple heating processes, the unit offers constant speed stability and reliable heat transfer for reproducible results. Efficient mixing and gentle heating power The stirrer is based on an energy-efficient, brushless EC motor with a speed range of 100 to 1,500 revolutions per minute. With a heating power of 600 watts, the instrument heats sample media quickly and directly up to a hotplate temperature of 310 °C (room temperature plus the instrument’s own heat generation). One litre of water achieves a heating rate of around 5.5 kelvin per minute. The magnetic coupling keeps the stir bar reliably on track even as the viscosity of the medium begins to change, whilst a gentle start-up mode also prevents the stir bar from becoming disengaged during the critical start-up phase. Robust aluminium heating plate for everyday laboratory use At the heart of the IKA RH lite is its round heating plate, 135 millimetres in diameter, made from an aluminium alloy with enhanced surface strength for a long service life. The self-heating of the base surface is limited to around 6 kelvin when stirring at maximum speed (based on a room temperature of 22 °C over one hour), which facilitates the mixing of temperature-sensitive samples. The housing is made from a durable plastic composite that protects the electronics from spills and allows for easy, residue-free cleaning of the unit’s surfaces. Safety-oriented operation for everyday laboratory use The RH lite features an adjustable temperature safety circuit in accordance with the laboratory equipment standard EN IEC 61010-2-010 for heated instruments, which can be set within a range of 50 to 360 °C. Two rotary/push buttons on the front panel allow independent setting of the target temperature, as well as separate start and stop functions for heating and stirring, even when wearing laboratory gloves. Thanks to its compact footprint, measuring 168 x 100 x 217 millimetres (width x height x depth), the magnetic stirrer can be integrated into any laboratory workstation or fume hood in a space-saving manner, even when several stirring stations are required simultaneously. Weighing just 2.1 kilograms, the unit can also be easily moved between different workstations. Typical applications As a cost-effective entry-level instrument, the RH lite is suitable for routine tasks in teaching laboratories, practical sessions and analytical work where reliable stirring and heating are required without complex additional functions: Preparing and heating buffers, reagents and nutrient solutions in routine laboratory operations Homogenising and mixing solutions with stirring volumes of up to 15 litres of water Heating aqueous solutions up to a hotplate temperature of 310 °C Use in training and practical sessions where a robust and cost-effective instrument is required Processes requiring a long service life, thanks to a robust aluminium heating plate with enhanced surface strength Technical details Number of stirring points1 Max. stirring capacity per stirring point (H₂O)15 litres Motor power / motor type7 W, brushless DC motor (EC) Speed range100 to 1,500 rpm Control systemTwo rotary/push buttons (with scale) for setpoint and for starting/stopping heating and stirring Max. stir bar length20 to 80 mm Heating power600 W Heating temperature rangeRoom temperature (plus self-heating) up to 310 °C Heating rate (1 l H₂O)5.5 K/min Temperature safety circuitAdjustable, 50 to 360 °C, in accordance with EN IEC 61010-2-010 Heating plate materialAluminium alloy Heating plate dimensionsØ 135 mm Housing materialChemical-resistant plastic composite Overall dimensions (W x H x D)168 x 100 x 217 mm Net weight2.1 kg Degree of protection according to DIN EN 60529IP 22 Power supply220 to 230 V, 50/60 Hz, power consumption 620 W Scope of delivery 1 x IKA RH lite magnetic stirrer base unit (MPN 0020007108) 1 x mains lead 1 x operating instructions Important note: Magnetic stir bars, stand rods and laboratory glassware are not included as part of the standard scope of delivery and must be ordered separately according to your specific application.

Electromagnetic rotational kinematics in microvolumes The homogenisation of aqueous or low-viscosity samples in portable field diagnostics requires compact systems with a highly efficient ratio of energy consumption to mechanical torque transmission. The IKA topolino mobil operates as a purely electromagnetic stirrer (without a thermodynamic heating function) and is limited, in process engineering terms, to a maximum working volume of 250 ml (based on water). The miniaturised drive train generates a continuously variable rotating magnetic field that synchronises the magnetic stir bar in the vessel at a frequency of 300 to 1,800 revolutions per minute. This asymmetric speed range makes it possible to generate gentle diffusion flows at low frequencies for sensitive colorimetric titrations, whilst the maximum speed generates a strong axial flow vortex to mix reagents microkinetically in fractions of a second. Energy self-sufficiency and system isolation The fundamental innovation of this model lies in its complete energy decoupling from the mains supply. The topolino mobil is primarily powered by rechargeable NiMH batteries (AA standard) or conventional batteries. This infrastructural self-sufficiency makes the system ideally suited for use in self-contained glove boxes, anaerobic workbenches or compact CO₂ incubators, where the routing of stationary power cables through the housing walls would compromise the system’s tightness (and thus the aerosol containment or the atmosphere). With a battery life of approx. 8 to 12 hours (depending on viscosity), the unit can also be used in the field, far from laboratory infrastructure. Tribological material architecture and system statics Despite its extreme miniaturisation, the device is subject to the chemical and physical requirements of instrumental analysis. The monolithic housing and base are entirely injection-moulded from high-density polypropylene (PP). This thermoplastic polymer exhibits excellent structural integrity and is highly chemically inert towards accidentally spilled acids, bases or organic solvents. The absence of a heating element avoids thermal stress on the housing material and unintended heat transfer to the sample. Technical details Kinematics & fluid mechanics Operating principle: Electromagnetic rotation Maximum stirring volume (H₂O): 250 ml Speed range: 300 – 1,800 rpm Speed adjustment: Continuously variable via analogue rotary potentiometer Maximum magnetic stir bar length: 30 mm Motor power input / output: 1.2 W / 0.8 W Motor type: Brushless DC motor (wear-free) Energy management & self-sufficiency Primary power supply: Mains-independent rechargeable or battery operation (AA / Mignon) Maximum running time (rechargeable battery operation): approx. 8 to 12 hours (depending on viscosity) Secondary power supply: Mains adapter for continuous stationary operation Charging function: Integrated; charges rechargeable batteries whilst the device is connected to the mains Materials science & dimensions Housing / base material: Polypropylene (PP) Base dimensions: Ø 70 mm System dimensions (W x H x D): 140 x 40 x 73 mm Weight: 0.13 kg (excluding batteries) Safety & environmental conditions Permissible ambient temperature range: 5 – 40 °C (suitable for incubators) Permissible relative humidity: max. 80 % IP rating (according to DIN EN 60529): IP 20 Electrical & infrastructure Voltage / frequency (mains adaptor): 100 – 240 V / 50/60 Hz DC input on the device: 9 V Current consumption: 300 mA Scope of delivery 1 x IKA topolino mobil magnetic stirrer 4 x rechargeable NiMH batteries (type AA) 1 x plug-in power supply (incl. adapter) (Important note: Magnetic stir bars for creating agitation in the vessel are not included!) Individual requirements & accessories The topolino mobil generates pure electromagnetic rotation, but requires a suitable rotor in the medium to induce the flow. Due to the spatial limitations of the system and the induced magnetic field, the length of the magnetic stir bar must not exceed the maximum of 30 mm; otherwise, at higher frequencies, the rotor will be thrown out of the magnetic field (decoupled) due to asymmetric slip. For aqueous micro-assays, we recommend standard PTFE-coated IKAFLON stir bars (20 mm or 30 mm). Please contact our procurement service at any time for the fluid-dynamically correct configuration of your mobile setup.

Electromagnetic rotational kinematics and micro fluid mechanics The homogenisation of aqueous or low-viscosity matrices on a laboratory scale requires compact, high-frequency power transmission. The IKA color squid white operates as a purely electromagnetic stirrer (without a thermodynamic heating unit) and is process-technically limited to a maximum hydrodynamic working volume of 1 L (based on water). The drive unit generates a continuously modulatable, high-frequency alternating magnetic field, which synchronises the rotor (stir bar) in the reaction vessel at a frequency of 0 to 2,500 revolutions per minute. This asymmetrically wide speed range generates an extremely steep axial flow funnel (vortex) even at minimal volumes. The resulting centrifugal force maximises molecular mass transfer (mixing kinetics) in fractions of a second and physically eliminates dead zones within the reaction vessel. Amorphous glass matrix and high chemical resistance The materials science architecture of the base (Ø 115 mm) is fundamentally designed for tribological and chemical resistance. The chassis is coated with a monolithic layer of tempered real glass. This amorphous silicate structure is resistant to many aggressive chemicals, halogens, strong acids and alkalis, which would irreversibly corrode conventional metallic or polymer housings in the event of accidental spillage. Exceptions include hydrofluoric acid and hot concentrated alkalis. The glass also physically prevents the accumulation of microbial biofilms and can be thoroughly decontaminated. As the system is thermodynamically decoupled (no heating matrix), the thermolabile matrix in the reaction vessel is not denatured by heat radiation induced from the surface on which it is placed. Electronic commutation The mechanical drive train is based on an electronically commutated motor (EC motor). The complete absence of mechanical carbon brushes eliminates tribological wear and frictional resistance, thereby qualifying the system for uninterrupted continuous operation (100 % duty cycle) at a constant kinetic power (3 W). Metrological control of the stirring process is carried out via a digital LED display. The processor-controlled electronics implement speed changes without delay and show the set speed on the display. Technical details Kinematics & Fluid Mechanics Processing principle: Electromagnetic rotation Maximum stirring volume (H₂O): 1 L Speed range: 0 – 2,500 rpm Speed display: Digital LED display Speed adjustment: Continuously variable via button interface Maximum magnetic stir bar length: 30 mm Motor power input / output: 3 W / 2 W Motor principle: Electronically commutated DC motor (wear-free) Materials science & dimensions Base material: Hardened real glass (amorphous silicate matrix) Colour scheme / design: White (white background with IKA logo) Base dimensions: Ø 115 mm System dimensions (W x H x D): 145 x 45 x 160 mm Machine weight: 0.54 kg Housing material: Chemical-resistant plastic with glass lid Safety & Environmental Conditions Permissible ambient temperature range: 5 – 40 °C Permissible relative humidity: max. 80 % IP rating (according to DIN EN 60529): IP 54 (protection against dust and water spray from all directions) Thermal conditions: No heating function; physical protection for thermolabile samples Electrical & Infrastructure Voltage / frequency (mains adaptor): 100 – 240 V / 50/60 Hz DC input on the unit: 12 V Current consumption: 300 mA Power consumption: max. 4 W Scope of delivery 1 x IKA color squid white magnetic stirrer 1 x mains power supply (including adapter) Important note: Magnetic stir bars for generating kinetics in the fluid are essential for process operation and are not included in the scope of delivery! Due to the compact geometry of the magnetic field, the use of rotors with a maximum length of 30 mm is a metrological requirement to prevent asymmetric slip (decoupling) at high frequencies. Individual requirements & accessories As a pure drive unit, the color squid white does not generate mixing as long as the magnetic field lines are not transferred to a rotor in the vessel. For optimum fluid dynamic turbulence in 1 L Erlenmeyer flasks or beakers, we recommend purchasing cylindrical, PTFE-coated IKAFLON magnetic stir bars (e.g. in lengths of 20 mm or 30 mm). To safely retrieve the contaminated rotors from the solution, you will also need a long PTFE magnetic stir bar retriever. Please contact our procurement service at any time for assistance with configuring your micro-homogenisation infrastructure.

Electromagnetic Rotational Kinematics and Fluid Mechanics The homogeneous mixing of aqueous or low-viscosity matrices on a laboratory scale requires a compact, high-frequency power transmission system. The IKA myPlate operates as a purely electromagnetic stirrer (without a thermodynamic heating unit) and is designed for a hydrodynamic working capacity of up to 1.5 L (based on water). The brushless drive generates a continuously variable rotating magnetic field that synchronises the rotor in the reaction vessel at a frequency of 0 to 2,500 revolutions per minute. This asymmetrically wide speed range creates a massive axial flow vortex. The resulting centrifugal forces and shear stresses maximise molecular mass transfer (mixing kinetics) and completely eliminate fluid dynamic dead zones in the beaker or Erlenmeyer flask. Amorphous glass matrix and optical system architecture The materials science architecture of the large base (Ø 135 mm) is based on a monolithic layer of tempered real glass. This amorphous silicate structure is resistant to many aggressive chemicals, strong acids and alkalis, which would irreversibly corrode conventional plastic housings in the event of a spill. Exceptions include hydrofluoric acid and hot concentrated alkalis. A distinctive feature of this chassis’s design is the integrated, tool-free removable interchangeable frame. This allows the instrument’s surface to be visually customised by inserting individual printed media, without blocking the magnetic field lines or compromising the metrological enclosure. As the system is thermodynamically decoupled, thermal stress on thermolabile samples from the base plate is avoided. Capacitive operation The mechanical drive train is implemented via an electronically commutated motor (EC motor). The absence of mechanical sliding contacts eliminates tribological wear, reduces power consumption to a low 4 W and qualifies the system for continuous operation without thermal stress. Metrological control of the process is carried out via a capacitive sensor keypad (touch slider) and a digital LED display. The integrated sensor technology translates the manual swiping gesture instantly into an incremental adjustment of the rotational speed and provides visual feedback on the speed. Technical details Kinematics & Fluid Mechanics Process principle: Electromagnetic rotation Maximum stirring volume (H₂O): 1.5 L Speed range: 0 – 2,500 rpm Speed display: Digital LED display Speed adjustment: Capacitive touch slider Maximum stir bar length: 30 mm Motor power input / output: 4 W / 2 W Motor type: Electronically commutated DC motor (EC motor) Materials Science & Systems Architecture Base material: Tempered real glass (amorphous silicate matrix) Modular design: Integrated interchangeable frame for visual customisation Base dimensions: Ø 135 mm System dimensions (W x H x D): 152 x 30 x 164 mm Machine weight: 0.5 kg Housing material: High-performance plastic with real glass cover Safety & environmental conditions Permissible ambient temperature range: 5 – 40 °C Permissible relative humidity: max. 80 % IP rating (to DIN EN 60529): IP 54 (protection against dust and splashing water) Thermal influence: None, as it is a purely kinetic unit without a heating matrix Electrical & Infrastructure Voltage / frequency (mains adaptor): 100 – 240 V / 50/60 Hz DC input on the unit: 12 V Current consumption: 300 mA Scope of delivery 1 x IKA myPlate magnetic stirrer 1 x mains power supply (including adapter) 1 x blank paper insert for personalisation Important note: Magnetic stir bars for hydrodynamic energy transfer into the fluid are essential for operation and are not included in the scope of delivery! Due to the magnetic pole spacing within the chassis, only stir bars with a maximum length of 30 mm may be used to prevent asymmetric flow separation (decoupling). Individual requirements & accessories The IKA myPlate generates a rotating magnetic field but, without a suitable rotor, does not induce any mechanical flow vectors. For maximum efficiency in 1.5 L beakers, we recommend using cylindrical, PTFE-coated IKAFLON magnetic stir bars (max. 30 mm in length). To retrieve the magnetic stir bars without contamination after homogenisation, you will also need a PTFE magnetic stir bar retriever. Please contact our procurement service at any time for the fluid-dynamically correct configuration of your stirring setup.

Anyone who regularly stirs a whole series of identical samples in parallel, for example, in quality control, in series of experiments or in laboratory classrooms with many groups working simultaneously, will quickly reach the limits of space and cost when using individual magnetic stirrers. The IKA RT 15 (0003692600) accommodates 15 heated stirring positions in a 90-millimetre grid, driven by a single coil drive instead of 15 individual motors, with a speed deviation of 0 % between the positions. Shared coil drive instead of individual motors Unlike 15 separate magnetic stirrers, the RT 15 operates using silent coil drive technology that powers all 15 stirring positions simultaneously. According to the data sheet, the speed variation between the individual positions is 0 %; all positions therefore run synchronously at the same set speed of 0 to 1,000 revolutions per minute, adjustable in increments of 10 revolutions per minute. 15 stirring positions in a uniform 90-millimetre grid The base, made from an aluminium alloy, measures 270 x 495 millimetres and is designed to accommodate 15 standard vessels in a 90-millimetre grid. Up to 0.4 l of water is provided per stirring position; in total, the unit can carry a maximum load of 15 kilograms. Stir bars measuring 25 to 30 millimetres in length are suitable for the individual positions. Heating function with a total power output of 580 watts The integrated heating system covers a temperature range from room temperature to 120 °C, with a total heating power of 580 watts for all 15 positions combined. The safety limit can be set between 50 and 150 °C. A silicone mat supplied with the unit protects the surface on which it is placed and, according to the manufacturer, ensures optimised temperature distribution across the positions. Silent drive with no mechanical wear The coil drive technology generates the rotating field for all 15 positions electronically, without any mechanically moving drive elements such as belts or gears at each stirring point. This not only reduces noise levels during continuous operation but also minimises maintenance requirements compared to a bench comprising 15 individual, mechanically driven stirrers, where each motor has its own wear parts. Typical applications With synchronously operating multiple stations, the RT 15 is suitable for: Parallel batch tests with identical stirring and heating parameters across 15 batches Quality control with recurring sample series in routine laboratories Training laboratories where several workstations are required to operate simultaneously at the same speed Solution preparation for sample series of up to 0.4 l per station A space-saving alternative to several individual heated magnetic stirrers Selection guide: single-station or multi-station stirrer Anyone who regularly stirs more than three to four identical batches in parallel should weigh up the cost of a multi-station stirrer against that of several individual units: ModelStirring positionsHeatingStirring capacity per stationPower supply RT 15 (this unit)15Yes, 580 W0.4 l230 V mains voltage RT 1010Yes, 375 W0.4 l230 V mains voltage RO 1010No0.4 l24 V, external power supply If heating is required in addition to stirring, the RT series is suitable. If stirring alone without heating is sufficient, the RO series with its 24-volt power supply saves on initial purchase costs and ongoing electricity costs. For smaller series of up to 10 samples, the RT 10 is also available within the RT series, which requires fewer positions whilst maintaining the same grid layout. Differences between the RT 10 and RO 10 The most significant difference within the multi-station series lies between the RT and RO models: The IKA RT 10 shares the same heating function and 230-volt mains voltage as the RT 15, but offers only 10 stirring positions instead of 15, with a correspondingly lower heating power of 375 watts instead of 580 watts. The IKA RO 10 does not have a heating function at all and is instead powered by an external 24-volt power supply; this is the key factor in the purchasing decision: those who only need to stir, but do not need to heat, are better served by the RO series.

Use, installation, maintenance and disposal With an IP 40 protection rating, the RT 15 is protected against solid foreign objects from 1 millimetre in size; however, it is not splash-proof. Accordingly, the unit should be operated on a dry, level surface and not in the immediate vicinity of sources of splashing water. The supplied silicone mat should be checked regularly for damage and cleaned if necessary, as it protects against both mechanical contact and uneven heat distribution. Before moving the device, which, at 10.5 kilograms, is comparatively heavy, it should be allowed to cool down and disconnected from the mains. At the end of its service life, as an electrical appliance, the device must not be disposed of with household waste but must be placed in the separate collection scheme for waste electrical and electronic equipment; the manufacturer’s WEEE registration number is DE 66784213. Investment logic: Multi-position stirrer versus multiple individual units For series work involving many small, similar samples of up to 0.4 l per position, the RT 15 is generally more cost-effective than 15 individual heated magnetic stirrers, both in terms of purchase cost and in terms of space required on the laboratory bench and cabling requirements, as only a single mains cable is required instead of 15 individual connections. The 0 % speed deviation between stations also ensures comparable results across all positions, an advantage over multiple individual units with potentially slightly differing calibration. If, on the other hand, only a few samples need to be processed in parallel or larger stirring volumes per vessel are required, individual C-MAG or RCT/RET units with a higher stirring volume per position are the more suitable choice. Individual requirements and procurement service Suitable original accessories are available for the RT 15 as required, such as magnetic stir bars in various shapes, beaker lids, a stir bar remover and power cables for different country variants (EU, USA, UK, Switzerland). Through our procurement service, we also assist you with spare parts and the uniform equipping of several series workstations. Further information and contact details can be found at our procurement service. Frequently Asked Questions Do all 15 stirring stations really operate at the same speed?Yes, according to the data sheet, the speed variation between the stations is 0 %, made possible by the shared coil drive rather than individual motors. Can each stirring station be heated individually?According to the data sheet, the heating power of 580 watts is specified for all stations combined; all stations share the same setpoint temperature. How does the RT 15 differ from the RO 10?The RT 15 heats and operates on a 230-volt mains supply, whilst the RO 10 does not have a heating function and is powered by an external 24-volt power supply; however, it offers only 10 stirring positions instead of 15. What is the maximum size of a stirring vessel per position?According to the data sheet, up to 0.4 l of water per stirring position is permitted; the spacing between positions is 90 millimetres, which is sufficient for standard test tubes and small beakers. Are stir bars included in the scope of delivery?No, the RT 15 is supplied without stir bars for the 15 stirring positions; suitable PTFE-coated magnetic stir bars in various shapes are available separately from the IKA range of accessories. Is the RT 15 suitable for continuous operation with multiple parallel batches?The silent coil drive technology, which does not use individual mechanical motors, is designed for long-term, low-maintenance continuous operation. How does the RT 15 differ from the RT 10?The RT 15 offers 5 additional stirring positions and correspondingly higher heating power (580 instead of 375 watts), whilst otherwise featuring identical operating logic and the same 90-millimetre grid. How should the RT 15 be disposed of correctly?As an electrical appliance, it should be taken to a waste electrical and electronic equipment (WEEE) collection point rather than disposed of with household waste; the manufacturer’s WEEE registration number is listed in the section on ‘Use, installation, maintenance and disposal’.

Not every laboratory needs as many as 15 parallel stirring stations; 10 synchronously operating positions are often sufficient for standard sample series. The IKA RT 10 (0003691100) offers exactly that: 10 heated stirring stations in a 90-millimetre grid, driven by a single coil drive rather than individual motors, with a speed deviation of 0 % between the stations. Shared coil drive for consistent results Like the larger models in the series, the RT 10 uses silent coil drive technology instead of individual motors for each position. According to the data sheet, the speed variation between the 10 positions is 0 %; all positions run synchronously at the same set speed of 0 to 1,000 revolutions per minute, adjustable in increments of 10 revolutions per minute. 10 stirring positions in a uniform 90-millimetre grid The base, made from an aluminium alloy, measures 180 x 495 millimetres, smaller than that of the RT 15, but with the same 90-millimetre grid for standard vessels. Up to 0.4 l of water is provided per stirring position; the maximum load capacity of the unit is 10 kilograms. Stir bars measuring 25 to 30 millimetres in length are suitable for the individual positions. Heating function with a total output of 375 watts The integrated heating system covers a temperature range from room temperature to 120 °C, with a total heating power of 375 watts for all 10 positions combined. The safety limit can be set between 50 and 150 °C. A silicone mat, supplied as standard, protects the surface on which the unit is placed and, according to the manufacturer, ensures optimised temperature distribution. Silent drive with no mechanical wear The coil drive technology generates the rotating field for all 10 positions electronically, without any mechanically moving drive elements such as belts or gears at each stirring point. This not only reduces noise levels during continuous operation but also minimises maintenance requirements compared with a bench comprising 10 individual, mechanically driven stirrers. Typical applications With multiple stations operating in synchronisation, the RT 10 is suitable for: Parallel sample series with identical stirring and heating parameters across 10 batches Routine laboratories carrying out regularly recurring series of tests Training laboratories with several workstations operating simultaneously Solution preparation for sample series of up to 0.4 l per station A space-saving alternative to several individual heated magnetic stirrers, on a smaller scale than the RT 15 Selection guide: 10 positions, 15 positions or without heating The choice between the RT 10, RT 15 and RO 10 depends primarily on the number of positions required and whether heating is necessary: ModelStirring positionsHeatingCapacityPower supply RT 10 (this unit)10Yes, 375 W10 kg230 V mains voltage RT 1515Yes, 580 W15 kg230 V mains voltage RO 1010No10 kg24 V, external power supply If more than 10 parallel stations are required, the RT 15 is the more suitable choice. If simple stirring without heating is sufficient, the RO 10, with its 24-volt power supply, offers lower purchase costs than the RT 10. Differences between the RT 15 and RO 10 The IKA RT 15 shares the same heating technology and 230-volt mains voltage as the RT 10, but offers 15 stirring stations instead of 10, with a correspondingly higher heating power of 580 watts instead of 375 watts, for larger series. The IKA RO 10 has the same number of stirring positions as the RT 10, but does not feature a heating function at all and is powered by an external 24-volt power supply. This is the key factor in the purchasing decision: those who only need to stir, but do not need to heat, are better served by the RO 10.

Use, installation, maintenance and disposal With an IP 40 protection rating, the RT 10 is protected against solid foreign objects from 1 millimetre in size; however, it is not splash-proof. Accordingly, the unit should be operated on a dry, level surface away from sources of splashing water and direct solvent vapours. The supplied silicone mat should be checked regularly for damage, as it protects against both mechanical contact and uneven heat distribution. Before moving the unit, which weighs 7.5 kilograms, it should be allowed to cool down and disconnected from the mains. At the end of its service life, as an electrical appliance, the unit must not be disposed of with household waste but must be placed in the separate collection for waste electrical and electronic equipment; the manufacturer’s WEEE registration number is DE 66784213. Investment logic: 10 positions as a starting point for series work For laboratories that regularly process between 5 and 10 identical batches in parallel, the RT 10 is often the more economical choice compared to the larger RT 15, both in terms of purchase price and the space required on the bench, as well as the cabling requirements, since only one mains cable is needed instead of several individual connections. If requirements exceed 10 parallel stations, a comparison should be made between purchasing a second RT 10 and switching directly to the RT 15; the latter generally saves space, reduces cabling effort and minimises the number of mains connections compared with two smaller units. If heating is not required, the RO 10, which offers the same number of workstations, is the more cost-effective alternative. Individual requirements and procurement service Suitable original accessories are available for the RT 10 as required, such as magnetic stir bars in various shapes, beaker lids, a stir bar remover and power cables for different country variants (EU, USA, UK, Switzerland). Through our procurement service, we can also assist you with spare parts and the uniform equipping of several series workstations. Further information and contact details can be found at our procurement service. Frequently Asked Questions Do all 10 stirring positions really operate at the same speed?Yes, according to the data sheet, the speed variation between the positions is 0 %, made possible by the shared coil drive rather than individual motors. What happens if I need more than 10 parallel stations?For larger series, IKA offers the RT 15 in the same series, featuring 15 stirring stations in the same 90-millimetre grid and a correspondingly higher total heating power of 580 watts. How does the RT 10 differ from the RO 10?The RT 10 heats and operates on 230-volt mains voltage, whilst the RO 10 does not have a heating function and is powered by an external 24-volt power supply. What is the maximum size of a stirring vessel per position?According to the data sheet, up to 0.4 l of water per stirring position is permitted; the spacing between positions is 90 millimetres. Are stir bars included in the scope of delivery?No, suitable stir bars for the individual positions must be purchased separately; the range of accessories includes PTFE-coated stir bars in various shapes. Can the RT 10 be set up alongside other laboratory equipment to save space?With a footprint of 180 x 495 millimetres and external dimensions of 190 x 60 x 610 millimetres, the RT 10 is designed as a narrow, elongated unit for installation along a laboratory bench. Is it worth opting for a single RT 15 instead of two RT 10s?Where there is a long-term requirement for more than 10 stirring positions, a single RT 15 with 15 positions is often more space-saving and cost-effective than two separate RT 10 units with double the cabling. Can the RT 10 be combined with the RT 15 to cover more stations?Both units can be operated side by side independently of one another; the manufacturer’s specifications do not provide for joint control or synchronisation between two separate units. How should the RT 10 be disposed of correctly?As an electrical appliance, it should be taken to a waste electrical and electronic equipment (WEEE) collection point rather than disposed of with household waste; the manufacturer’s WEEE registration number is listed in the section ‘Use, installation, maintenance and disposal’.

Not every routine task in the laboratory requires a heating function; often, the only requirement is reliable, synchronised and uniform stirring at room temperature across multiple positions. The IKA RO 10 (0003691000) is the pure stirring variant of the multi-position series: 10 stirring positions in a 90-millimetre grid without heating, powered by an external 24-volt power supply rather than direct mains voltage, with a speed deviation of 0 % between positions. Shared coil drive without heating function Like the heated RT models, the RO 10 utilises silent coil drive technology, which drives all 10 stirring positions collectively rather than via individual motors. According to the data sheet, the speed variation between the positions is 0 %; the speed range extends from 0 to 1,200 revolutions per minute, which is slightly higher than that of the heated RT models at 1,000 revolutions per minute. Operates via an external 24-volt power supply Unlike the RT 10 and RT 15, which are powered directly from a 230-volt mains supply, the RO 10 runs via an external power supply unit delivering 24 volts DC and drawing a current of 1,000 milliamps. The power supply unit itself accepts an input of 100 to 240 volts and has a power consumption of 24 watts. This design is typical for devices without a heating load, where the lower overall power consumption allows for a low-voltage supply. Stainless steel base and anti-slip film The base is made of 1.4301 stainless steel and measures 190 x 470 millimetres in a 90-millimetre grid, providing 10 positions. A removable, transparent anti-slip film is included in the scope of delivery and ensures that vessels do not slip on the smooth stainless steel surface. Stir bars measuring 25 to 30 millimetres in length are suitable for the individual positions. Silent drive with no mechanical wear As with the heated RT models, the coil drive technology generates the rotating field for all 10 positions electronically, without any mechanically moving drive elements at each stirring point. Combined with the enclosed, compact design, this results in a low-maintenance unit for continuous series use, where, unlike with multiple individual motors, there are no wear parts at each stirring point that require monitoring. Typical applications As a pure stirring variant without a heating function, the RO 10 is technically suitable for: Parallel stirring processes without temperature requirements, such as homogenisation or dissolution at room temperature Routine laboratories where a heating function is not required and purchase costs are a consideration Environments with low-voltage requirements, such as in certain training situations Batches of samples up to 0.4 l per position with uniform, synchronised speed As a supplement to existing heating sources such as separate water baths Selection guide: with or without heating The most important decision within the multi-station series is whether heating is required: ModelStirring positionsHeatingSpeed rangePower supply RO 10 (this unit)10No0 to 1,200 rpm24 V, external power supply RT 1010Yes, 375 W0 to 1,000 rpm230 V mains voltage RT 1515Yes, 580 W0 to 1,000 rpm230 V mains voltage If heating is required in addition to stirring, the RT 10 or RT 15 are suitable. If stirring alone is sufficient, the RO 10 saves on both the initial purchase cost and ongoing electricity costs compared to the RT models, and even achieves a slightly higher maximum speed range. Differences between the RT 10 and RT 15 The IKA RT 10 shares the same 10 stirring positions on a 90-millimetre grid as the RO 10, but also features a heating function with a total power output of 375 watts and is powered directly from a 230-volt mains supply rather than via an external power supply unit. The IKA RT 15 offers a further 5 stirring positions, including heating, for larger series, also in a 90-millimetre grid and with the same 0 % speed deviation. Anyone who only needs to stir but requires more than 10 stations should weigh up this requirement against two RO-10 units or an RT-15 solution with an unused heating function.

Use, installation, maintenance and disposal With an IP 40 protection rating, the RO 10 is protected against solid foreign objects from 1 millimetre in size; it is not splash-proof, so the unit should be operated on a dry, level surface. The stainless steel base is chemical-resistant and easy to clean; the transparent anti-slip film can be removed and replaced as required. As the unit is powered by an external 24-volt power supply, the cable should be checked regularly for damage. At the end of its service life, as an electrical appliance, the device must not be disposed of with household waste but must be placed in the separate collection scheme for waste electrical and electronic equipment; the manufacturer’s WEEE registration number is DE 66784213. Investment rationale: When it pays to do without heating If stirring is carried out exclusively at room temperature, or if a heat source is already available elsewhere, such as a separate water bath, the RO 10 offers a lower purchase cost than the RT 10 with the same number of stations, without compromising on stirring performance or synchronisation between the stations. Operating electricity consumption is also correspondingly lower due to the absence of the heating load. If it is foreseeable that heating will also be required, switching directly to the RT 10 is generally more cost-effective than retrofitting at a later date, as a heating function cannot be retrofitted to an RO unit. Individual requirements and procurement service Suitable original accessories are available for the RO 10 as required, such as magnetic stir bars in various shapes, beaker lids and a stir bar remover, as well as certificates and documentation for IQ/OQ qualification. Through our procurement service, we also assist you with spare parts and the uniform equipping of several series workstations. Further information and contact details can be found at our procurement service. Frequently Asked Questions Why is the RO 10 powered by 24 volts rather than direct mains voltage?As there is no heating load, a low-voltage supply via an external power supply unit, which accepts 100 to 240 volts at the input, is sufficient. Can a heating function be retrofitted at a later date?No, the RO 10 is designed purely as a stirring unit; for heating requirements, the RT 10, which has an identical design, is available. Do all 10 stirring positions really run at the same speed?Yes; according to the data sheet, the speed variation between the positions is 0 %. Is the external power supply included in the scope of delivery?The unit operates on 24-volt DC with a current draw of 1,000 milliamps; we can provide the identification number of the supplied power supply on request; the power supply itself accepts 100 to 240 volts at the input. What is the anti-slip film for?It prevents vessels from slipping on the smooth stainless steel base and can be removed if required. Why is the speed range on the RO 10 higher than on the RT 10?According to the data sheet, the speed range of the RO 10 extends up to 1,200 revolutions per minute instead of 1,000; this is a model-specific difference that exists independently of the lack of a heating function and may be useful for very low-viscosity media. Is the RO 10 suitable for use alongside a separate water bath?Yes, as it does not have its own heating function, the RO 10 can be combined well with a separately temperature-controlled water bath or circulating thermostat. Can the RO 10 be combined with an RT model?Both series of units can be operated independently of one another, for example where some workstations require heating whilst others only need stirring. How should the RO 10 be disposed of correctly?As an electrical appliance, it should be taken to a collection point for waste electrical and electronic equipment rather than disposed of with household waste; the manufacturer’s WEEE registration number is listed in the section on ‘Use, installation, maintenance and disposal’.
