Promotional item of the IKA Specials Q4/2026, valid until 31 December 2026. The struck-through price is IKA's recommended retail price. Our promotional price is net.The IKA RW 20 digital stirrer (MPN 0003593000) is the digital further development of the proven RW 20 series and combines a mechanically controlled drive with an LED digital display for the speed. Anyone who regularly has to move stirring volumes of up to 20 litres of water in the laboratory and wants to switch between powerful, low-speed and fast, high-speed stirring will find a robust working tool for daily use here.Mechanical gearbox with two speed rangesThe RW 20 digital has a gearbox with two speed ranges that is switched manually by lever. Range I covers 60 to 500 rpm and delivers a high torque of up to 150 Ncm at the stirring shaft, suitable for highly viscous media of up to 10,000 mPas, pastes or larger volumes. Range II extends from 240 to 2,000 rpm and is suitable for low-viscosity media and fast dispersing. At a mains frequency of 50 hertz, the ranges are 60 to 500 rpm (range I) and 240 to 2,000 rpm (range II), and at 60 hertz correspondingly 72 to 600 rpm and 288 to 2,400 rpm. The maximum torque at the stirring shaft is 150 Ncm at 100 rpm and falls to 24 Ncm at 1,000 rpm; for a short time, an overload of up to 300 Ncm is even permissible at 60 1/min.Precision through LED digital displayWhile power transmission is mechanical, the integrated LED digital display on the front of the unit ensures a speed that can be read at any time and is reproducible. Setting is continuous, the setting accuracy is ±1 rpm, and the deviation of the speed measurement is ±30 rpm. The nominal torque of the drive is 1.5 Nm at a power consumption of 70 watts and an output power of 35 watts. The unit is designed for continuous operation at 100 percent duty cycle.Pass-through hollow shaft for flexible height adjustmentA practical detail in everyday laboratory work is the pass-through stirring shaft (hollow shaft) with an internal diameter of 10.5 millimetres. It makes it possible to adjust the height of the stirring tool in the chuck (clamping range 0.5 to 10 millimetres) without having to realign the entire stirrer on the stand. The shaft is adjusted at standstill only. The boss rod for mounting on the stand has a diameter of 13 millimetres and a length of 160 millimetres.Typical applicationsWith its high torque in the lower speed range and a stirring volume of up to 20 litres, the RW 20 digital is technically suited for:Universal stirring tasks in the laboratory with changing batch sizesHomogenising and dispersing medium-viscosity to higher-viscosity media of up to 10,000 mPasTeaching and industrial laboratories with frequently changing usersRoutine operation in which it is necessary to switch between powerful and fast stirringSelection guide: stirring mechanically or electronicallyWithin the IKA stirrer range, the RW 20 digital described here, with its mechanically controlled drive, is contrasted by the compact NANOSTAR 7.5 digital with electronic BLDC control. For stirring volumes of up to 20 litres, high torque in the lower speed range and robust continuous operation, the RW 20 digital is the right choice. If, on the other hand, no more than 5 litres are moved and a particularly compact, electronically controlled design is required, for example in tight space conditions in a fume hood, the NANOSTAR 7.5 digital is the more space-saving alternative.Differences from larger models of the RW seriesIf a stirring volume of 20 litres is not sufficient for the planned batch, IKA continues the mechanical RW series in larger sizes: the RW 28 digital for stirring volumes of up to 80 litres and the RW 47 digital for stirring volumes of up to 200 litres. For the majority of laboratory applications with batches of up to 20 litres, the RW 20 digital described here remains the more compact and more economical choice.Technical detailsMax. stirring volume (H2O)20 lMax. viscosity10,000 mPasSpeed controlmechanicalSpeed range I / II60 to 500 rpm / 240 to 2,000 rpm (at 50 Hz)Speed range I / II (60 Hz)72 to 600 rpm / 288 to 2,400 rpmSpeed setting methodcontinuousSetting accuracy / speed deviation±1 rpm / ±30 rpmSpeed displayLEDMotor power, input / output70 W / 35 WNominal torque1.5 NmMax. torque at the stirring shaft150 Ncm (at 100 rpm), 300 Ncm overload at 60 1/minTorque at the stirring shaft at 1,000 rpm24 NcmMax. power at the stirring shaft26 WPermissible duty cycle100 %Stirring tool mountingChuck, clamping range 0.5 to 10 mmHollow shaft, internal diameter10.5 mm, pass-through at standstillStand mountingBoss rod, Ø 13 mm, length 160 mmProtection classIP 20 according to DIN EN 60529Dimensions (W x H x D)88 x 294 x 212 mmWeight3.1 kgConnection values220 to 240 V, 50/60 Hz, 72 W (other voltage variants 100 to 115 V available)Scope of delivery1 x RW 20 digital1 x chuck keyA stand and a cross clamp for mounting as well as a suitable stirring tool are required for operation but are not included in the scope of delivery.Use, installation, maintenance and disposalAccording to protection class IP 20, the RW 20 digital is protected against solid foreign objects from 12.5 millimetres, and contact with splashing water must be avoided. The switching lever for the two speed ranges should only be operated with the motor stopped, as should the height adjustment of the pass-through hollow shaft in the chuck. For a secure stand, a sufficiently heavy stand with a stable cross clamp is recommended, especially when using the high torque in the lower speed range. At the end of its service life, the unit as electrical equipment does not belong in household waste but in the separate collection of waste electrical equipment.Individual requirements & procurement serviceOperating the RW 20 digital requires a stand (for example an IKA base plate stand), a suitable cross clamp and a stirring tool matched to the application, for example propeller, turbine, anchor or dissolver stirrers. A stirring shaft guard or a quick-release chuck can also be added if required. Through our procurement service , we will gladly put together a suitable stirring set-up for you from our range of stirring and mixing technology .Frequently asked questionsIs a stand included in the scope of delivery?No, a stand, cross clamp and stirring tool are required for operation but are not included in the scope of delivery.What is the maximum stirring volume possible with the RW 20 digital?Up to 20 litres of water, at a maximum permissible viscosity of 10,000 mPas.How do you switch between the two speed ranges?Via a mechanical lever on the front of the unit, which should only be operated with the motor stopped.Can the stirring tool be adjusted in height without moving the stand?Yes, via the pass-through hollow shaft in the chuck, adjustable at standstill.Is there an electronically controlled model as an alternative?For more compact applications of up to 5 litres, the electronically controlled NANOSTAR 7.5 digital is suitable.What happens if the stirring shaft is overloaded?For a short time, an overload of up to 300 Ncm at the stirring shaft is permissible at 60 1/min; beyond that, the load should be reduced.

With a torque of 80 Ncm and a mixing capacity of up to 50 litres of water, the MINISTAR 80 control is the most powerful model in the entire MICROSTAR/MINISTAR series, designed for samples up to 60,000 mPas at speeds ranging from 0/30 to 500 revolutions per minute. Whilst speed is the key feature of the smaller models, it is power that counts here above all else, whilst the housing and weight are virtually identical to those of the MINISTAR 40 control.LCD display with temperature measurement and timerAs with the other ‘control’ models, the difference compared to the structurally identical MINISTAR 80 lies in the digital display and additional functions. An LCD glass display shows speed, temperature and a timer ranging from 0 to 6,000 minutes; the supplied H 67.60 stainless steel temperature probe measures via PT1000 in the range from -10 to 350 degrees Celsius. A torque display provides a trend value, not a calibrated absolute measurement. A micro-USB port and an integrated WPAN interface (Bluetooth) connect the device to labworldsoft.Drive for heavy loadsThe brushless DC motor draws 60 watts and delivers up to 42 watts to the stirring shaft, with a duty cycle of 100 per cent in continuous operation. The chuck accommodates stirring shafts from 0.5 to 8.2 mm; the hollow shaft with an 8.5 mm internal diameter can be inserted whilst the unit is stationary. On the stand, the unit is mounted on an arm with a diameter of 13 mm and a length of 160 mm. A vibration detection system switches off the drive as soon as the stirring tool becomes unbalanced, an important safeguard for both the motor and the sample, particularly at this torque level.Robustness for continuous useThe speed is adjusted via a rotary knob with an accuracy of ±1 rpm; above 300 rpm, the deviation is a maximum of ±1 per cent. A button lock prevents the setting from being accidentally altered whilst the unit is running, particularly with the larger, longer-running batches for which this model is typically used. The chemical-resistant housing, made of coated cast aluminium and thermoplastic, is protected against dust and splashing water in accordance with IP 54; permissible ambient temperatures range from 5 to 40 degrees Celsius with up to 80 per cent relative humidity.Typical applicationsLarge batches of up to 50 litres in production and pilot plantsStirring of highly viscous samples up to 60,000 mPasTemperature-controlled processes with PT1000 monitoringDocumented stirring logs via labworldsoft for applications requiring high torqueBatches that would otherwise require a larger, stationary stirrerSelection guide: an overview of the MICROSTAR/MINISTAR seriesTwelve models make up the MICROSTAR and MINISTAR series from IKA: six in the ‘control’ version and six in the structurally identical ‘digital’ version.

Mixing small volumes at high speed without a batch foaming up or remaining uneven: that is the core task of the IKA MICROSTAR 7.5 digital. The overhead stirrer covers stirring volumes of up to 5 litres of water per stirring position and turns at up to 2,000 revolutions per minute, with a maximum torque of 7.5 Ncm at the stirring shaft. For cell culture batches, analytical sample preparation and small reagent batches in the routine laboratory, exactly this combination of speed and small footprint is in demand.Speed reserve for low-viscosity mediaThe speed range starts at 50 rpm and extends up to 2,000 rpm, adjustable via a rotary knob with an accuracy of ±1 rpm. Up to a viscosity of 4,000 mPas, the torque remains constant over the entire range, so the unit does not noticeably drop off with thicker media. The motor power is 32 watts input and 22 watts output, and a maximum of 15.7 watts is available at the stirring shaft. For aqueous solutions, buffers and low-viscosity reagents in the laboratory, this power class is usually sufficient.Operation, display and connectionThe speed is shown on an LED display, and the digital model has no timer. The hollow shaft with an internal diameter of 8.5 mm can be passed through at standstill, and the chuck accepts tools from 0.5 to 8.2 mm. The firmware can be updated via the Micro-USB interface. At 60 x 173 x 126 mm (W x H x D) and 1.18 kg, the stirrer takes up little space on the laboratory bench, and it is mounted on a stand using a boss rod of 13 mm diameter and 160 mm length. The housing made of coated cast aluminium and thermoplastic is protected to IP 54, so dust and splashing water are not a problem in everyday laboratory use.Typical applicationsMixing cell culture batches of small volumeSample preparation in analyticsPreparing reagents and buffers in the routine laboratoryFormulation and quality control work with low-viscosity mediaSelection guide: MICROSTAR and MINISTAR at a glanceThe digital and control series of MICROSTAR and MINISTAR comprises twelve models, graded by torque, stirring volume and speed range. The MICROSTAR 7.5 digital covers the smallest stirring volume at the highest speed. The difference between digital and control lies in the display and additional functions: digital shows the speed by LED, while control adds an LCD display, timer and external temperature measurement.ModelMax. torqueStirring volume (H2O)Speed rangeDisplayMICROSTAR 7.5 digital (this product)7.5 Ncm5 l50 to 2,000 rpmLEDMICROSTAR 7.5 control7.5 Ncm5 l30 to 2,000 rpmLCDMICROSTAR 15 digital15 Ncm10 l50 to 1,000 rpmLEDMICROSTAR 15 control15 Ncm10 l30 to 1,000 rpmLCDMICROSTAR 30 digital30 Ncm20 l50 to 500 rpmLEDMICROSTAR 30 control30 Ncm20 l30 to 500 rpmLCDMINISTAR 20 digital20 Ncm15 l50 to 2,000 rpmLEDMINISTAR 20 control20 Ncm15 l30 to 2,000 rpmLCDMINISTAR 40 digital40 Ncm25 l50 to 1,000 rpmLEDMINISTAR 40 control40 Ncm25 l30 to 1,000 rpmLCDMINISTAR 80 digital80 Ncm50 l50 to 500 rpmLEDMINISTAR 80 control80 Ncm50 l30 to 500 rpmLCDTechnical detailsMax. stirring volume per stirring position (H2O)5 lMotor power, input32 WMotor power, output22 WMotor principleBrushless DCSpeed displayLEDSpeed range0/50 - 2000 rpmMax. viscosity4000 mPasMax. power at the stirring shaft15.7 WPermissible duty cycle100 %Max. torque at the stirring shaft7.5 NcmSpeed setting accuracy±1 rpmStirring tool mountingChuckChuck clamping range0.5 to 8.2 mmHollow shaft, internal diameter8.5 mmStand mountingBoss rodBoss rod diameter13 mmBoss rod length160 mmHousing materialCoated cast aluminium / thermoplasticPermissible ambient temperature range5 - 40 °CPermissible relative humidity80 %InterfaceUSB (Micro-USB)Connection values100 to 240 V, 50/60 Hz, device power consumption 32 W (standby 0.3 W), DC voltage 24 V=, current consumption 1300 mA, Micro-USB interface for firmware updatesProtection classIP 54 (DIN EN 60529)Dimensions (W x H x D)60 x 173 x 126 mmWeight1.18 kgScope of delivery1 x MICROSTAR 7.5 digital stirrer, basic unit1 x stirring shaft guard R 300, with fixing screws (2 pieces)1 x chuck keyWarranty and procurement serviceIKA grants a 2-year manufacturer's warranty on the MICROSTAR 7.5 digital, extended to 10 years when registered at ika.com/register within 90 days of purchase.

Positioned between the entry-level MINISTAR 20 and the MINISTAR 80, which offers the highest torque, is the IKA MINISTAR 40 digital: 25-litre mixing capacity, 40 Ncm torque and a speed range of 50 to 1,000 rpm, designed for media with a viscosity of up to 30,000 mPas.Mid-range model with performance reserveWith a power consumption of 60 watts and an output of 46 watts, the motor performance is in line with the rest of the MINISTAR range; the rated torque is 0.4 Nm. Compared with the MINISTAR 20 digital, the maximum torque is almost doubled, whilst the mixing capacity increases by 10 litres. For formulations that become thicker during processing, the speed remains stable across the entire viscosity range.Connection and housingMeasuring 70 x 193 x 147 mm and weighing 1.72 kg, the housing is identical to that of the MINISTAR 80 digital; only the internal gear ratio distinguishes the two models. The power consumption is 69 watts (0.5 watts on standby); as with the entire series, the micro-USB port is used exclusively for firmware updates. The chuck accommodates tools from 0.5 to 8.2 mm; the hollow shaft, with an internal diameter of 8.5 mm, can be inserted whilst the machine is stationary.Accessories for the MINISTAR seriesFor larger batches in plastic vessels, an anchor stirrer with a beaker scraper is available, which also picks up the medium from the vessel wall. The range of accessories also includes propeller, disc and centrifugal stirrers for different flow conditions, as well as telescopic and plate stands for mounting. For personal safety when working with an open stirring vessel, in addition to the R 300 included in the Scope of delivery, a separately available R 301 stirring shaft guard with its own stand mount is provided. Those working in a regulated environment can order factory calibration certificates and IQ/OQ documentation for the qualification of the device. The corresponding EU Declaration of Conformity is available in the downloads section of the product documentation, as is the German-language operating instructions.Typical applicationsBatches of up to 25 litres with increasing viscosity as the process progressesFormulation development on a pilot scaleHomogenisation of thicker suspensions and pastesProcesses requiring greater power reserve than the MICROSTAR series can provideSelection guide: MICROSTAR and MINISTAR at a glanceThe MINISTAR 40 digital sits in the middle of the MINISTAR range, offering twice the torque of the MINISTAR 20 digital and half that of the MINISTAR 80 digital.

With a more powerful motor (60 watts power consumption instead of 32 watts) and a larger housing, IKA’s MINISTAR range picks up where the MICROSTAR models reach their limits. The MINISTAR 20 control stirs up to 15 litres of water at a torque of 20 Ncm and, with speeds ranging from 0/30 to 2,000 revolutions per minute and a viscosity of up to 10,000 mPas, covers a wide range, from low-viscosity to medium-viscosity samples.LCD display, timer, PT1000 sensorAs with the other control models, the main difference between this and the structurally identical MINISTAR 20 digital lies in the display. A glass LCD display shows speed, temperature and a timer ranging from 0 to 6,000 minutes. The supplied H 67.60 stainless steel temperature probe measures temperatures in the range from -10 to 350 degrees Celsius via a PT1000 sensor, with readings displayed directly on the screen. A torque reading is shown as a trend; it is not a calibrated absolute measurement. A micro-USB port and an integrated WPAN interface (Bluetooth) connect the stirrer to labworldsoft.More motor power, same operating conceptThe MINISTAR 20 control’s brushless DC motor draws 60 watts and delivers up to 42 watts to the stirring shaft, significantly more than the MICROSTAR models. The chuck accommodates stirring shafts from 0.5 to 8.2 mm; the hollow shaft with an 8.5 mm internal diameter can be inserted whilst the unit is stationary. The unit is held in place on the stand by an arm with a diameter of 13 mm and a length of 160 mm. A vibration detection system automatically switches off the motor if the stirring tool is running out of balance.Housing and permissible operating environmentThe speed can be adjusted via the rotary knob with an accuracy of ±1 rpm; the measurement deviation is a maximum of ±1 per cent above 300 rpm. A button lock protects the current setting from accidental adjustment, for example during cleaning. The housing, made of coated cast aluminium and thermoplastic, is chemical-resistant and protected against dust and splashing water in accordance with IP 54. Permissible ambient temperatures range from 5 to 40 degrees Celsius, with a relative humidity of up to 80 per cent.Typical applicationsBatches of up to 15 litres requiring greater power than MICROSTAR modelsStirring of low- to medium-viscosity samples up to 10,000 mPasTemperature-controlled processes with PT1000 monitoringLaboratory tests at high speeds (up to 2,000 rpm) with documented curves via labworldsoftTransition range between compact MICROSTAR and large-volume MINISTAR applicationsSelection guide: an overview of the MICROSTAR/MINISTAR seriesTwelve models make up the MICROSTAR and MINISTAR series from IKA, six in the ‘control’ version and six in the structurally identical ‘digital’ version.

Anyone who has to stir a batch volume of 20 litres with media of up to 20,000 mPas viscosity needs more torque than speed. The IKA MICROSTAR 30 digital delivers up to 30 Ncm at the stirring shaft at a speed range of 50 to 500 rpm, making it the highest-torque version of the MICROSTAR series.Constant torque at lower speedThe speed range only extends up to 500 rpm, but in return the torque remains constant up to 20,000 mPas viscosity, considerably more than the MICROSTAR 15 digital with 8,000 mPas. The motor power is unchanged at 32 watts input and 22 watts output, and the nominal torque rises to 0.3 Nm. For thicker suspensions, pastes and higher-viscosity reaction batches in the laboratory, the MICROSTAR 30 digital is the right choice within the MICROSTAR range.Same design, more powerExternally, the MICROSTAR 30 digital differs hardly at all from its smaller siblings: 60 x 173 x 126 mm, 1.26 kg weight, boss rod mounting with 13 mm diameter and 160 mm length. The stirring tool is attached via a chuck with a clamping range of 0.5 to 8.2 mm, and the hollow shaft with an internal diameter of 8.5 mm can be passed through at standstill. Protection class IP 54 and the ambient temperature range of 5 to 40 °C apply as for all digital models of the series.Stirring elements for higher viscosityFor higher-viscosity batches, the accessories range offers above all anchor and helical stirrers, which engage the medium closer to the vessel wall than a simple propeller stirrer. For the MICROSTAR series, the helical stirrer R 3003 and the anchor stirrers R 1330 and R 1331 are available, among others. In addition, we carry base plate stands, telescopic stands and cross clamps for mounting, as well as a separate stirring shaft guard R 301 with stand holder for personal protection at an open vessel.

With a mixing capacity of 100 l and a torque of 200 Ncm, the EUROSTAR 200 digital forms part of IKA’s classic range, which has been tried and tested for many years and continues to be manufactured alongside the newer digital LCD generation. Instead of an LCD display, a 7-segment LED display shows the speed; two switchable speed ranges cover both low-speed, high-torque applications and rapid stirring of thinner media. For anyone looking for a robust, straightforward agitator without additional electronics, the EUROSTAR 200 digital is the right choice. It shares the motor, gearbox and base housing with the EUROSTAR 200 control and can be swapped for the better-equipped model at any time if required, without altering the stability on the stand.Two speed ranges for two tasksIn Range I, the stirrer delivers a torque of up to 200 Ncm at speeds between 6 and 400 rpm, suitable for viscous media and large stirring tools. In range II, the speed increases to up to 2,000 rpm, whilst the torque drops to a maximum of 40 Ncm, making it suitable for low-viscosity samples that require rapid stirring rather than high torque. The microprocessor-controlled system maintains the set speed constantly, even if the viscosity of the sample changes during the stirring process. According to the manufacturer, viscosities of up to 100,000 mPas are possible.Mechanics and connectionThe brushless DC motor draws 130 watts and delivers up to 84 watts to the stirring shaft. Stirring shafts are mounted via a 10 mm diameter plug-in coupling and a collet chuck ranging from 0.5 to 10 mm; the hollow shaft, with an internal diameter of 10.3 mm, can be inserted whilst the unit is stationary. With an IP 42 rating, the degree of protection is lower than that of the newer digital LCD models, but this is sufficient for standard laboratory use. An electronic safety circuit cuts off power in the event of a fault or overload, and an error code is displayed directly on the screen. The unit is also available in voltage versions of 100 to 115 V and 100 V, which is useful for locations outside the European 230 V mains supply or for replacing an older stirrer on the same circuit.Typical applicationsPowerful stirring of viscous media up to 100 l in Zone IRapid stirring of low-viscosity samples up to 2,000 rpm in range IIRobust continuous operation without display electronics or additional wireless functionsMixing processes with viscosities up to 100,000 mPasSelection guide: the EUROSTAR series at a glanceSix EUROSTAR models make up IKA’s current range.

With a mixing capacity of 150 l and a torque of 400 Ncm, the EUROSTAR 400 digital is the most powerful digital model in the classic EUROSTAR series, designed for pilot plants and large batches involving viscous to highly viscous media. The larger chuck, wider housing and more powerful motor clearly distinguish this unit from the smaller EUROSTAR 200 models, whilst the operating logic, featuring two speed ranges and a 7-segment LED display, remains the same. Anyone who regularly runs batches of over 100 l or works with viscous, high-viscosity formulations will find this to be the most powerful version available without additional wireless functions.Power for large batchesIn low-speed range I, the mixer delivers up to 400 Ncm of torque at speeds between 6 and 400 rpm; in the faster range II, the speed reaches up to 2,000 rpm with a maximum torque of 80 Ncm. According to the manufacturer, viscosities of up to 100,000 mPas are possible; the brushless DC motor draws 220 watts and delivers up to 176 watts to the stirring shaft. The chuck accommodates stirring shafts with diameters ranging from 3 to 16 mm, significantly more than the smaller models in the series, to suit the larger stirring tools used with batch sizes of 150 l. The speed can be adjusted continuously with an accuracy of ±1 rpm; the digital LED display shows the current value directly on the unit.Design and connectionMeasuring 114 x 325 x 245 mm and weighing 8.4 kg, the unit is noticeably larger and heavier than the 200 series models; a correspondingly sturdy stand with a 16 mm arm diameter is therefore essential. The hollow shaft, with an internal diameter of 10.3 mm, can be inserted whilst the unit is stationary; the housing, made of coated cast aluminium and thermoplastic, is protected against foreign bodies larger than 1 mm and dripping water when tilted up to 15° in accordance with IP 42. An electronic safety circuit cuts off the power in the event of a fault or overload; additional voltage variants of 115 V and 100 V are available for locations outside the 230 V mains supply. The 16 mm extension arm is shorter than that of the 200 series models; however, whilst having the same diameter, it supports the greater weight of the larger stirring shafts and tools more stably on the stand.Typical applicationsStirring large batches of up to 150 l in pilot plants and technical centresPowerful mixing of viscous to highly viscous media up to 100,000 mPasRapid stirring of thinner samples in the higher-speed range IIContinuous operation with larger stirring tools from 3 mm shaft diameterUpgrading from a 200-series model as batch volumes increaseSelection guide: the EUROSTAR series at a glanceSix EUROSTAR models make up IKA’s current range; the EUROSTAR 400 digital, together with its ‘control’ counterpart, represents the highest performance tier.

When the batch volume rises above 10 litres or a stirrer is to run permanently with a higher power reserve, you switch from the MICROSTAR to the MINISTAR series. The IKA MINISTAR 20 digital is the entry into this class: 60 watts motor input power, a stirring volume of up to 15 litres of water per stirring position and a speed range of 50 to 2,000 rpm at a maximum torque of 20 Ncm.More motor power than MICROSTARWith 60 watts input and 46 watts output power, the motor is almost twice as powerful as in the MICROSTAR series, and up to 42 watts are available at the stirring shaft. Up to a viscosity of 10,000 mPas, the torque remains constant. This power reserve is noticeable above all in continuous operation, when a stirrer runs under load over longer periods, for example in continuous processes in the pilot laboratory.Larger housing, same operating logicAt 70 x 193 x 147 mm and 1.56 kg, the MINISTAR 20 digital is noticeably larger and heavier than the MICROSTAR models. Operation and display remain the same: set the speed by rotary knob, the LED display shows the value, and a chuck with a clamping range of 0.5 to 8.2 mm holds the stirring tools. The current consumption rises to 2,900 mA, corresponding to the higher motor power. For batches in plastic vessels, an anchor stirrer with beaker scraper is also available for this series.Further accessories for the MINISTAR seriesIn addition to the anchor stirrer with beaker scraper, the accessories range for this series includes dissolver and disc stirrers for higher shear forces as well as telescopic and base plate stands for mounting. Anyone working with weighing can also use a matching balance stand. For personal protection at an open vessel, a separately available stirring shaft guard R 301 with its own stand holder is available in addition to the supplied R 300.Typical applicationsEntry to larger batch volumes from 15 litresContinuous operation in the pilot laboratory with increased power reserveProcesses with medium viscosity up to 10,000 mPasTransition from laboratory to pilot plant scaleSelection guide: MICROSTAR and MINISTAR at a glanceThe MINISTAR 20 digital is the entry-level model of the MINISTAR line, with the same stirring volume as the MICROSTAR 15 digital but almost twice the motor power.

The RW 20 digital Package is the compact entry-level model in IKA’s mechanical RW series and comes complete with a stand, cross-sleeve and propeller stirrer. The set can stir up to 20 l of water, with a torque of up to 150 Ncm. For those looking for a stirrer that is ready for immediate use without having to purchase a stand and stirring element separately, this package offers the ideal solution for smaller batches in the laboratory.Two speed ranges for small batchesIn range I, the speed is between 60 and 500 rpm (at 50 Hz); the torque at the stirring shaft reaches up to 150 Ncm, and up to 300 Ncm for short periods under overload at 60 1/min. In Range II, the speed increases to up to 2,000 rpm. The speed can be adjusted continuously, with an accuracy of ±1 rpm. According to the manufacturer, the basic unit can handle viscosities of up to 10,000 mPas; it is designed for thin to medium-viscosity media, which is significantly less than the 50,000 mPas of the larger RW 28 digital.Set components and mechanicsIn addition to the RW 20 digital base unit, the package includes the R 1826 plate stand, the R 182 cross-sleeve and the R 1342 four-bladed propeller stirrer. The chuck accommodates stirring shafts with a diameter between 0.5 and 10 millimetres; the hollow shaft, with an internal diameter of 10.5 mm, can be inserted even when the unit is at a standstill. The bracket for mounting the stand measures 13 mm in diameter and 160 mm in length; a temperature limiter protects the motor from overheating.Dimensions and weight of the base unitThe weight of 3.1 kg and the dimensions of 88 x 294 x 212 mm stated in the data sheet refer to the RW 20 digital base unit alone. We can provide the total weight for the complete set, including the stand, cross-sleeve and propeller stirrer, on request; for dispatch planning purposes, the actual parcel weight is correspondingly higher than this figure. The basic unit has an IP 20 protection rating.Additional stirring elements for the base unitIn addition to the supplied R 1342 propeller stirrer, IKA offers a wide range of stirring elements for the RW 20 digital: axially conveying propeller and centrifugal stirrers as well as helical stirrers, radially conveying dissolvers and disc stirrers, and the tangentially operating anchor stirrer R 1330. Also available as accessories are additional plate stands, a clamping holder, a stirrer shaft guard, a beaker lid and a flexible coupling.

In everyday laboratory work the highest speed is rarely what is needed, but rather reliable stirring performance for batches between 5 and 10 litres at medium viscosity. The IKA MICROSTAR 15 digital covers exactly this window with a torque of up to 15 Ncm and a stirring volume of up to 10 litres of water per stirring position, at a speed range of 50 to 1,000 rpm. The overhead stirrer is thus the middle model of the MICROSTAR series, between the faster MICROSTAR 7.5 and the higher-torque MICROSTAR 30.Stirring performance up to 8,000 mPasUp to a viscosity of 8,000 mPas, the unit keeps its torque constant over the entire speed range. Besides aqueous solutions, this allows mixing of medium-viscosity media such as creams, emulsions or reaction mixtures of increasing consistency. The motor power of 32 watts input and 22 watts output is identical to the smaller MICROSTAR 7.5 digital, and the higher torque of 15 Ncm results from the gearing, not from a stronger motor.Design and operationAt 60 x 173 x 126 mm and 1.26 kg, the MICROSTAR 15 digital differs hardly at all in appearance from the MICROSTAR 7.5 digital, and its weight is only 80 grams higher. The speed is set by rotary knob with ±1 rpm accuracy and shown on an LED display. The chuck with a clamping range of 0.5 to 8.2 mm, the hollow shaft with an internal diameter of 8.5 mm and protection class IP 54 correspond to the rest of the digital series. The unit is mounted on a stand using a boss rod of 13 mm diameter and 160 mm length.Accessories from the current rangeFor different stirring tasks, stirring elements with axial, radial and tangential flow direction are available from the accessories range of the series, from simple propeller stirrers to anchor and disc stirrers. In addition, we carry base plate stands, telescopic stands and cross clamps for mounting, as well as a separate stirring shaft guard R 301 with its own stand holder for personal protection at an open vessel, in addition to the R 300 included in the scope of delivery.Typical applicationsMixing batches of up to 10 litres in the standard laboratoryStirring creams, emulsions and reaction mixtures of medium viscosityRoutine testing in quality control and goods receivingPreparing reagents and test solutions for downstream analyticsSelection guide: MICROSTAR and MINISTAR at a glanceWithin the MICROSTAR line, the MICROSTAR 15 digital sits in the middle performance class, between the faster 7.5 and the higher-torque 30.

The RW 28 digital is part of IKA’s mechanical RW series, which runs alongside the electronically controlled EUROSTAR series and is designed for highly viscous media. The unit can agitate up to 80 litres of water, with a torque of up to 900 Ncm in the lower speed range. Anyone who regularly handles larger batches in a technical laboratory or pilot plant and prefers robust, straightforward mechanics to additional electronic functions will find the RW 28 digital to be a workhorse capable of continuous operation at 100 per cent duty cycle.Two speed ranges for power and speedIn range I, the speed is between 60 and 400 rpm (at 50 Hz); the torque at the stirring shaft reaches up to 900 Ncm here, and up to 1,144 Ncm for short periods under overload at 60 rpm. In Range II, the speed increases to up to 1,400 rpm, whilst the torque drops to a maximum of 300 Ncm. The speed can be adjusted continuously, with an accuracy of ±1 rpm and a measurement deviation of ±10 rpm. An LED display shows the set value; there is no LCD display or wireless connectivity, as offered by IKA’s newer digital LCD generation. For the classic RW mechanism, which has been tried and tested for years, this is sufficient for everyday laboratory use.Mechanics and connectionThe chuck accommodates stirring shafts with a diameter between 1 and 10 millimetres; the hollow shaft, with an internal diameter of 10.5 mm, can be inserted even when the unit is at a standstill. The arm for mounting on a stand measures 16 mm in diameter and 145 mm in length. According to the manufacturer, the stirrer can handle viscosities of up to 50,000 mPas. A temperature limiter protects the motor from overheating, whilst an electronic overload protection system switches the unit off in the event of a fault and displays an error code on the screen. The unit operates on the European mains supply at 220 to 240 volts; other voltage variants at 115 V and 100 V are available. The protection class is IP 40; the housing is made of coated cast aluminium with thermoplastic components. Without a mixing tool, the unit achieves a sound pressure level of 62.5 dB(A) and thus remains comparatively quiet even during continuous operation.Agitator elements and safety accessoriesFor a variety of mixing tasks, IKA offers a wide range of mixing elements for the RW 28 digital: axial-flow propeller and centrifugal mixers, radial-flow dissolvers and disc mixers, as well as tangential-flow paddle and anchor mixers. In addition, there are stands in various designs, ranging from the simple H-bar to the floor stand, as well as cross-sockets and clamping holders for mounting. A stirrer shaft guard with a matching stand mount is available as an optional safety accessory; it covers the free-running shaft during operation. For environments requiring validation, IKA also provides qualification and factory calibration certificates, as well as IQ/OQ documents for the unit.Typical applicationsIntensive stirring of highly viscous media up to 80 litres in laboratory and pilot plantsContinuous operation at 100 per cent duty cycle without any loss of performancePowerful stirring in range I, faster stirring of thinner samples in range IIRobust operation without display electronics or additional wireless functionsPosition within the RW seriesWithin the mechanical RW series, the RW 28 digital is the mid-range model. For smaller batches of up to 20 litres requiring lower torque, the RW 20 digital Package is suitable as a ready-to-use complete set with a stand; for batches of up to 200 litres and 3,000 Ncm, the RW 47 digital with three-phase connection is recommended. Those looking for electronic speed control with an LCD display instead of mechanical control will find an alternative in the EUROSTAR series, such as the EUROSTAR 200 digital with a comparable stirring capacity.Technical detailsMax. mixing capacity (H₂O)80 lMotor power input / output220 W / 90 WSpeed range I / II60 to 400 rpm / 240 to 1,400 rpmMax. torque I / II900 Ncm / 300 NcmMax. viscosity50,000 mPasChuck clamping range1 to 10 mmHollow shaft, internal diameter10.5 mm, can be inserted whilst stationaryArm diameter / length16 mm / 145 mmHousing materialCoated cast aluminium / thermoplasticNoise level without tools62.5 dB(A)Protection classIP 40 (DIN EN 60529)Permissible ambient temperature / humidity5 to 40 °C / 80 %Dimensions (W x H x D)123 x 364 x 252 mmWeight7.5 kgConnected load220 to 240 V, 50/60 Hz, 220 W (other voltage options: 115 V / 100 V)Scope of deliveryRW 28 digital mixer (base unit), ID no. 0005040000Chuck keyMixing tools, stand and mixing shaft guard are not included in the Scope of delivery and must be ordered separately.Warranty and procurement serviceIKA provides a manufacturer’s warranty for the RW 28 digital: 2 years, extended to 3 years upon registration at ika.com/register within 90 days of purchase.

In microchemical synthesis, during parallel sample preparation or when working under very cramped fume cupboards, the space required by laboratory instruments is often the limiting factor. The IKA NANOSTAR 7.5 digital stirrer (MPN 0025004356) is an extremely compact overhead stirrer whose housing is barely larger than an apple, yet is still capable of reliably homogenising, dispersing or dissolving media with a volume of up to 5 litres (based on the viscosity of water).Constant torque thanks to a brushless DC motorAt the heart of the NANOSTAR 7.5 digital is a brushless DC motor (BLDC technology), which operates wear-free and is largely maintenance-free, delivering a constant torque of 7.5 Ncm at the stirring shaft. If the viscosity of the medium changes during stirring, for example, due to an increase in viscosity during polymerisation or temperature fluctuations, the integrated electronics automatically adjust the power consumption. The set speed, within the range of 50 to 2,000 revolutions per minute, thus remains constant, which prevents uncontrolled flow disruption and ensures reproducible results. The maximum viscosity of the medium may be up to 4,000 mPas.Hollow shaft and chemical-resistant glass frontWhen changing mixing vessels or dealing with varying fill levels, the stirring tool often needs to be adjusted in height. The NANOSTAR 7.5 digital features a continuous hollow shaft with an internal diameter of 8.5 millimetres, through which the shaft of the stirring tool can be easily pushed when the unit is at a standstill, without the need to cut the stirring shafts to length. The unit is operated via a capacitive touch slider on an LED glass display. The seamless real-glass front is resistant to organic solvents, acid vapours and alkalis, and can therefore be thoroughly cleaned and decontaminated.IP 54 protection rating and digital connection via USBFor unattended operation, the NANOSTAR 7.5’s housing is digitally sealed to protection class IP 54, thereby protecting it from dust and splashing water from all directions. An electronic overload and overtemperature protection system automatically switches off the motor if the stirring element becomes blocked. The micro-USB port on the rear can be used to install firmware updates and connect the device to the Labworldsoft laboratory equipment software to document torque trends.Typical applicationsWith its compact design and constantly regulated torque, the NANOSTAR 7.5 digital is ideally suited for:Microchemical syntheses and reactions where space is limited within a fume cupboardParallel sample preparation at several workstations simultaneouslyHomogenisation and dispersion of small volumes up to 5 litresStirring processes involving changing viscosity, such as during polymerisationSelection guide: mechanical or electronic stirringWithin the IKA range of stirrers, the NANOSTAR 7.5 digital described here, with its electronically controlled BLDC drive, is complemented by the mechanically controlled RW 20 digital. For compact volumes up to 5 litres and confined spaces, the NANOSTAR 7.5 digital described here is the right choice. If, on the other hand, volumes of up to 20 litres need to be stirred or high torque is required in the lower speed range, the RW 20 digital with its mechanical gearbox is the more suitable alternative.Distinction from larger electronic overhead stirrersIf a larger stirring volume or higher torque is required than the NANOSTAR 7.5 digital offers with its 5 litres and 7.5 Ncm, IKA offers further electronically controlled overhead stirrers in larger sizes with the Ministar and Microstar series, which can be viewed in our range of stirring and mixing technology. For compact applications with limited space, however, the NANOSTAR 7.5 digital described here remains the most space-saving option in IKA’s range of electronic stirrers.Technical detailsMax. stirring volume (H₂O)5 lMax. viscosity4,000 mPasMotor typebrushless DC motor (BLDC)Speed range0/50 to 2,000 rpmSpeed adjustmentRotary knobSetting accuracy for speed±1 rpmSpeed measurement deviation±1 % (n > 300 rpm) / ±3 rpm (n < 300 rpm)Speed displayLED glass display with touch sliderMotor power, input / output32 W / 22 WRated torque0.075 NmMax. torque at the stirring shaft7.5 NcmMax. power at the stirring shaft15.7 WPermissible duty cycle100 %Agitator tool mountingChuck, clamping range 0.5 to 8.2 mmHollow shaft, internal diameter8.5 mm, can be inserted whilst the unit is stationaryMounting on standExtension arm, Ø 13 mm, length 160 mmHousing materialCoated cast aluminium / thermoplasticInterfaceUSB (Micro-USB)Standby power consumption0.3 WProtection ratingIP 54 in accordance with DIN EN 60529Dimensions (W x H x D)53 x 147 x 130 mmWeight0.8 kgConnected load100 to 240 V, 50/60 Hz, 32 WScope of delivery1 x NANOSTAR 7.5 digital (drive unit)1 x R 300 stirrer shaft guard2 x fixing screws for R 3001 x chuck keyA suitable mixing tool, a cross-sleeve and a stand are required for operation but are not included in the Scope of delivery.Use, installation, maintenance and disposalThanks to its IP 54 protection rating, the NANOSTAR 7.5 digital can withstand splash water and dust in a normal laboratory environment. The seamless glass front can be decontaminated using standard solvents, acids or alkalis without cleaning agents penetrating the joints or buttons. To ensure secure, vibration-free mounting, the motor should be fitted to a sufficiently stable tripod arm. 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.Individual requirements and procurement serviceThe NANOSTAR 7.5 digital is a drive motor only. To achieve suitable mixing in terms of fluid dynamics within a beaker or reaction vessel, a stirring device tailored to the sample is required, such as a propeller, centrifugal or anchor stirrer from the IKA R-series. For secure attachment to the stand arm, we also recommend a sturdy plate stand with a suitable cross-sleeve. Through our procurement service, we would be happy to put together a suitable stirring setup for you from our range of stirring and mixing equipment.Frequently Asked QuestionsIs a stirring tool included in the Scope of delivery?No, a stirring tool, cross-coupling and stand are required for operation but are not included in the Scope of delivery.What is the maximum stirring volume possible with the NANOSTAR 7.5 digital?Up to 5 litres of water, with a maximum permissible viscosity of 4,000 mPas.How is the speed kept constant when the viscosity changes?The integrated electronics of the brushless DC motor automatically adjust the power consumption.Can the mixing tool be fitted without shortening the shaft?Yes, via the push-through hollow shaft with an 8.5-millimetre internal diameter, which can be adjusted whilst the unit is stationary.Is the unit suitable for use with solvents?The seamless glass front is resistant to organic solvents, acid vapours and alkalis.Is there a mechanically controlled model for larger mixing volumes?For mixing volumes of up to 20 litres, the mechanically controlled RW 20 digital is ideal.

Five litres of water at a torque of 7.5 Ncm mark the smallest power level of the IKA MICROSTAR control series, but in return the stirrer turns at up to 2,000 revolutions per minute, faster than any other model in this family. For low- to medium-viscosity samples of up to 4,000 mPas, such as buffers, aqueous solutions or low-viscosity emulsions, the MICROSTAR 7.5 control is the right choice when speed matters more than volume.LCD display instead of indicator lightThe difference from the digital series of the same power class lies above all in the display and the additional functions. The MICROSTAR 7.5 control shows speed, time and temperature on a glass display in LCD technology, supplemented by a timer from 0 to 6,000 minutes. Using the supplied stainless steel temperature sensor H 67.60, the unit measures the sample temperature between -10 and 350 degrees Celsius and shows it directly on the display, an external PT1000 measurement that the digital models lack entirely. In addition, a torque display runs on the screen, although only as a trend and not as a calibrated absolute measurement, helpful for roughly detecting a change in the viscosity of the sample during a stirring series. Micro-USB and an integrated WPAN interface (Bluetooth) connect the stirrer to labworldsoft, IKA's measurement and control software.Mechanics for daily changeoverThe unit is held on the stand by a boss rod with 13 mm diameter and 160 mm length, and the chuck accepts stirring shafts from 0.5 to 8.2 mm and can be changed with the supplied chuck key. The hollow shaft with an internal diameter of 8.5 mm can be passed through at standstill, which is practical with stirring elements that are inserted from above. The brushless DC motor draws 32 watts and delivers up to 15.7 watts at the stirring shaft, at a duty cycle of 100 percent in continuous operation. If the stirring tool runs with imbalance, vibration monitoring detects this automatically and switches the unit off.Operation, housing and ambient conditionsThe speed is set via a rotary knob, with an accuracy of ±1 rpm and a deviation of at most ±1 percent above 300 rpm. A key lock prevents a running setting from being changed accidentally, for example when cleaning the unit. The housing is made of coated cast aluminium and thermoplastic, chemical-resistant and protected against dust and splashing water to protection class IP 54. Permissible ambient temperatures are 5 to 40 degrees Celsius at a relative humidity of up to 80 percent, values that are sufficient for most laboratory and pilot plant rooms.Typical applicationsHomogenising small batches in research and developmentTemperature-controlled stirring of reaction solutions with PT1000 monitoringStirring low- to medium-viscosity samples at high speedsLaboratory experiments with documented speed and temperature curves via labworldsoftSelection guide: the MICROSTAR/MINISTAR series at a glanceTwelve models make up the IKA MICROSTAR and MINISTAR series, six in the control version and six in the identically constructed digital version.

The EUROSTAR 400 control is the fully-equipped version of the most powerful classic EUROSTAR model, with a mixing capacity of 150 l and a torque of 400 Ncm, utilising the same mechanical components as its digital counterpart, plus a TFT display, a detachable WiCo controller and a connection for external PT1000 temperature measurement. For pilot plants where the temperature and torque curves of large batches need to be documented, the control model is the more suitable choice compared to the simpler digital unit. Those who do not require the WiCo controller can opt for the structurally identical EUROSTAR 400 digital and save on the additional electronics.WiCo controller and temperature measurement on a large scaleThe WiCo wireless controller transmits over a range of up to 150 metres, depending on the building layout, which is particularly useful for large mixing stations where the main unit is not directly accessible. Using the H 67.60 stainless steel temperature sensor included in the Scope of delivery, the unit measures temperatures between -10 and 350 degrees Celsius with a resolution of 0.1 K; the torque display shows a trend value for monitoring changes in viscosity. RS232 and micro-USB interfaces record the parameters via labworldsoft.Power, design and batteryThe brushless DC motor draws 220 watts and delivers up to 176 watts to the stirring shaft. In range I, the stirrer delivers up to 400 Ncm at speeds between 6 and 400 rpm; in range II, the speed reaches up to 2,000 rpm with a maximum of 80 Ncm. The chuck accommodates stirring shafts from 3 to 16 mm; measuring 114 x 345 x 268 mm and weighing 8.8 kg, the unit is slightly larger and heavier than the digital model due to the additional WiCo electronics. The WiCo controller contains a permanently fitted lithium-polymer cell with 3.7 V and 7.4 Wh, which is housed within the unit and cannot be removed separately. The protection rating is IP 42. Additional voltage variants of 115 V and 100 V are available for locations outside the European 230 V mains supply.Typical applicationsDocumented stirring of large batches up to 150 l with temperature and torque curvesRemote control via the detachable WiCo controller at hard-to-reach stirring pointsPowerful mixing of viscous to highly viscous media up to 100,000 mPasProcess development in pilot plants with RS232/USB connection to labworldsoftSelection guide: the EUROSTAR series at a glanceSix EUROSTAR models make up IKA’s current range; the EUROSTAR 400 control is the fully equipped variant in the highest performance class.

At the upper end of the MICROSTAR/MINISTAR series stands the IKA MINISTAR 80 digital: 50 litres stirring volume per stirring position, 80 Ncm torque and a design for media of up to 60,000 mPas viscosity, at a speed range of 50 to 500 rpm.For large and thick batchesWith a nominal torque of 0.8 Nm and a maximum stirring shaft power of 42 watts, the unit handles batches at which the smaller MICROSTAR models reach their limit. The speed range ends at 500 rpm, lower than with the entry-level MINISTAR 20 digital, because at this torque and viscosity class stirring performance is more important than speed.Identical in construction to MINISTAR 40, different gearingHousing dimensions (70 x 193 x 147 mm) and weight (1.72 kg) correspond exactly to the MINISTAR 40 digital, and the two models differ only in the internal gearing between speed and torque. The connected load of 69 watts, protection class IP 54 and operation via rotary knob and LED display are identical across the entire digital series. For setting up on reaction vessels of larger volume, additional stand accessories are available if required.Accessories for large batchesWith stirring volumes of up to 50 litres, suitable accessories from the current range pay off. In addition to the anchor stirrer with beaker scraper for plastic vessels, the range includes dissolver and disc stirrers for high shear forces as well as helical stirrers for thick, non-Newtonian media. Telescopic and base plate stands as well as cross clamps are available for mounting, and for personal protection at an open vessel, additionally a separately available stirring shaft guard R 301 with its own stand holder. For the regulated sector, factory calibration certificates and IQ/OQ documentation are also available, as is the EU declaration of conformity from the downloads area of the product documentation. Anyone who regularly works with plastic vessels additionally secures the stability of the set-up by using a base plate stand instead of a slim telescopic stand.Typical applicationsStirring large batches of up to 50 litres in the pilot laboratoryMixing highly viscous media of up to 60,000 mPasProcesses with high torque requirements at low speedTransition from laboratory to pilot plant scaleSelection guide: MICROSTAR and MINISTAR at a glanceThe MINISTAR 80 digital is the most powerful model of the entire series, with the highest torque and the largest stirring volume.

With a torque of 15 Ncm and a mixing capacity of up to 10 litres of water, the MICROSTAR 15 control sits in the middle of IKA’s MICROSTAR range, designed for samples up to 8,000 mPas at speeds ranging from 0/30 to 1,000 revolutions per minute. This model is suitable for applications that require more power than the 7.5 model but do not yet fall within the scope of the MINISTAR series with its larger housing.Display, timer and temperature sensorThe difference between the control model and the structurally identical MICROSTAR 15 digital is evident in the display. Instead of an LED display, the MICROSTAR 15 control has an LCD glass display which shows speed, temperature and a timer ranging from 0 to 6,000 minutes. The supplied H 67.60 stainless steel temperature probe measures the sample temperature between -10 and 350 degrees Celsius via a PT1000 measurement, which can be read directly on the display. A torque display is also included; however, it only shows a trend and not a calibrated absolute measurement. To document measurement series or for firmware updates, the device connects to labworldsoft via Micro-USB or the integrated WPAN interface (Bluetooth).Drive and mechanical connectionThe brushless DC motor draws 32 watts and delivers up to 15.7 watts to the stirring shaft, with a duty cycle of 100 per cent in continuous operation. The stirrer is mounted on the stand via a 13 mm diameter, 160 mm long extension arm; the chuck accommodates stirring shafts from 0.5 to 8.2 mm, which can be changed using the supplied chuck key. The hollow shaft, with an internal diameter of 8.5 mm, can be inserted whilst the unit is stationary. A vibration detection system automatically switches off the motor as soon as the stirring tool becomes unbalanced.Controls and operating conditionsA rotary knob controls the speed with an accuracy of ±1 rpm; above 300 rpm, the deviation is a maximum of ±1 per cent. A button lock protects a configuration once set from accidental adjustment. The housing, made of coated cast aluminium and thermoplastic, is designed to be chemical-resistant and is protected against dust and splashing water in accordance with IP 54. The MICROSTAR 15 control may be operated at ambient temperatures of 5 to 40 degrees Celsius and relative humidity of up to 80 per cent.Typical applicationsFormulation and batch preparations requiring moderate mixing powerTemperature-controlled stirring via the PT1000 sensorProcessing of medium-viscosity samples up to 8,000 mPasLaboratory routines with documented speed via labworldsoftSelection guide: an overview of the MICROSTAR/MINISTAR seriesTwelve models make up the MICROSTAR and MINISTAR series from IKA: six in the ‘control’ version and six in the structurally identical ‘digital’ version.

The motor, gearbox and mixing capacity of the EUROSTAR 200 control are exactly the same as those of the digital model in the same performance class, handling up to 100 l of water and 200 Ncm of torque at low speeds. The difference lies in the operation: a digital, multilingual TFT display, a detachable remote control called WiCo and a connection for an external PT1000 temperature sensor transform the basic unit into a stirrer with process documentation. Anyone wishing to record the temperature and torque curve of a reaction without having to stand by the stand is better off with the control model than with the digital model. The additional electronics do not alter either the stirring capacity or the basic mechanics; a later switch between the two versions is possible on the same stand without any modification.WiCo, TFT display and temperature measurementThe WiCo wireless controller can be detached from the base unit and transmits control signals wirelessly over a range of up to 150 metres, depending on the building layout; this is particularly useful for stirring points that are difficult to access or mounted within a fume cupboard. Using the optional H 67.60 stainless steel temperature probe, which is included in the Scope of delivery, the unit measures the sample temperature between -10 and 350 degrees Celsius with a resolution of 0.1 K. The torque display shows a trend value, which is helpful for detecting changes in the sample’s viscosity during stirring, although it does not replace a calibrated absolute measurement.Mechanics, connection and batteryThe brushless DC motor draws 135 watts and delivers up to 84 watts to the stirring shaft; the two speed ranges are from 6 to 400 rpm with a maximum of 200 Ncm and from 30 to 2,000 rpm with a maximum of 40 Ncm. Stirring shafts are mounted via a 10 mm diameter plug-in coupling and a collet ranging from 0.5 to 10 mm. RS232 and Micro-USB interfaces connect the device to labworldsoft. The WiCo controller contains a permanently installed lithium-polymer cell with 3.7 V and 7.4 Wh, which is housed within the unit and cannot be removed separately. The IP 40 protection rating is lower than that of the basic units without wireless electronics; however, this is sufficient for normal laboratory use on a stand.Typical applicationsDocumented stirring with temperature and torque curves via the PT1000 sensorRemote operation via the detachable WiCo controller, for example at a fume cupboardPowerful stirring of viscous media up to 100 l at low speedsProcess development with RS232/USB connection to labworldsoftSelection guide: the EUROSTAR series at a glanceSix EUROSTAR models make up IKA’s current range. The EUROSTAR 200 control shares the motor, gearbox and stirring capacity with the digital model in the same class, whilst also featuring a WiCo controller, TFT display and PT1000 temperature measurement.ModelMax. stirring capacity (H2O)Max. torqueMax. viscosityDisplay/FeaturesEUROSTAR 20 digital25 l40 Ncm10,000 mPasLCD, USB-C/RS232EUROSTAR 100 digital100 l200 Ncm (short-term)70,000 mPasLCD, USB-C/RS232EUROSTAR 200 digital100 l200 Ncm100,000 mPasLEDEUROSTAR 200 control (this product)100 l200 Ncm100,000 mPasTFT, WiCo, PT1000EUROSTAR 400 digital150 l400 N·cm100,000 mPasLEDEUROSTAR 400 control150 l400 Ncm100,000 mPasTFT, WiCo, PT1000For those stirring smaller volumes of up to 5 l, the MICROSTAR and MINISTAR series offer the ideal alternative, such as the MICROSTAR 7.5 control.Technical detailsMax. stirring capacity (H2O)100 lMotor power consumption135 WMotor power output84 WSpeed range I6 to 400 rpm, max. 200 NcmSpeed range II30 to 2,000 rpm, max. 40 NcmMax. viscosity100,000 mPasConnection for external temperature sensorPT1000, measuring range -10 to 350 °CChuck clamping range0.5 to 10 mmPlug-in connector10 mmHollow shaft, internal diameter10.3 mmWiCo communication range (depending on the building)max. 150 mWiCo controller battery1x LiPo, 3.7 V, 7.4 Wh, 55 g, permanently fitted in the unitProtection classIP 40 (DIN EN 60529)Dimensions (W x H x D)91 x 297 x 231 mmWeight4.9 kgConnected load230 V, 50/60 Hz, 135 W (other voltage options: 100 to 115 V / 100 V)Scope of deliveryEUROSTAR 200 control stirrer (basic unit), ID no. 0003992000Temperature probe H 67.60, stainless steel (PT1000)WiCo mounting bracket WH11WiCo power supply OS 1.0USB cable (USB-A to Micro-B), 2 mScrewdriverProtective cap for the WiCo contactChuck keyWarranty and procurement serviceIKA provides a manufacturer’s warranty for the EUROSTAR 200 control: 2 years, extended to 3 years upon registration at ika.com/register within 90 days of purchase.

With a mixing capacity of 20 litres and a torque of 30 Ncm, the MICROSTAR 30 control is the most powerful model in the MICROSTARrange, designed for samples up to 20,000 mPas at speeds ranging from 0/30 to 500 revolutions per minute. Whilst the 7.5 model focuses on speed, the emphasis here is on power and greater volume, whilst retaining the same compact housing dimensions of 60 x 173 x 136 mm.What the display shows in additionCompared to the structurally identical MICROSTAR 30 digital, the control version features an LCD glass display which shows not only the speed but also the temperature and a timer (0 to 6,000 minutes). The supplied PT1000 sensor H 67.60, made of stainless steel, measures the sample temperature in the range from -10 to 350 degrees Celsius. A torque display completes the set of readings; it provides a trend, not a calibrated absolute measurement. A micro-USB port and a WPAN interface (Bluetooth) are available for connection to labworldsoft, IKA’s measurement and control software.Design for higher load conditionsDespite the higher stirring rate, the brushless DC motor maintains a power consumption of 32 watts; the power at the stirring shaft is up to 15.7 watts, with a duty cycle of 100 per cent in continuous operation. The chuck accommodates stirring shafts from 0.5 to 8.2 mm; the hollow shaft, with an internal diameter of 8.5 mm, can be inserted whilst the unit is stationary. On the stand, the unit is mounted on an extension arm 13 mm in diameter and 160 mm long. A vibration detection system switches off the drive as soon as the mixing tool becomes unbalanced, a safety feature particularly important given the higher torques of this model.Housing, adjustment and permissible operating environmentThe speed can be adjusted via a rotary knob with an accuracy of ±1 rpm; the deviation is a maximum of ±1 per cent above 300 rpm. A button lock prevents accidental adjustment during operation. The chemical-resistant housing, made of coated cast aluminium and thermoplastic, is protected against dust and splashing water in accordance with IP 54. Permissible ambient temperatures range from 5 to 40 degrees Celsius at up to 80 per cent relative humidity, which is also sufficient for use in a pilot plant.Typical applicationsLarger batches of up to 20 litres in production and pilot plantsStirring of high-viscosity samples up to 20,000 mPasTemperature-controlled reactions with PT1000 monitoringDocumented stirring protocols via labworldsoftBatches where a compact housing is important despite a higher stirring volumeSelection guide: an overview of the MICROSTAR/MINISTAR seriesTwelve models make up the MICROSTAR and MINISTAR series from IKA: six in the ‘control’ version and six in the structurally identical ‘digital’ version.

25 litres of stirring volume and 40 Ncm of torque position the MINISTAR 40 control in the middle of the MINISTAR series, for samples of up to 30,000 mPas at speeds of 0/30 to 1,000 revolutions per minute. Compared with the MINISTAR 20 control, the focus is more on volume and viscosity than on high speed, while compared with the MINISTAR 80 control it retains more speed range for thinner phases within the same batch.What the control display showsThe MINISTAR 40 control differs from the identically constructed MINISTAR 40 digital by an LCD glass display, a timer from 0 to 6,000 minutes and external temperature measurement via the supplied sensor H 67.60 (PT1000, -10 to 350 degrees Celsius). A torque display additionally provides a trend value, not a calibrated absolute measurement. The unit can be connected to labworldsoft via Micro-USB or the WPAN interface (Bluetooth) to document measurement series.Mechanics for thicker samplesWith 60 watts input power and up to 42 watts at the stirring shaft, the brushless DC motor delivers enough power for the higher viscosity class of this model. The chuck accepts stirring shafts from 0.5 to 8.2 mm, and the hollow shaft with an internal diameter of 8.5 mm can be passed through at standstill. The boss rod for stand mounting measures 13 mm in diameter and 160 mm in length. If the stirring tool runs with imbalance, vibration detection automatically switches off the drive.Setting, housing and operating limitsThe rotary knob controls the speed with an accuracy of ±1 rpm, and above 300 rpm with a deviation of at most ±1 percent. The key lock holds a selected setting, even when the unit runs unattended during longer stirring series. Housings made of coated cast aluminium and thermoplastic are chemical-resistant and protected against dust and splashing water to IP 54. The MINISTAR 40 control may be operated at 5 to 40 degrees Celsius ambient temperature and up to 80 percent relative humidity, values that cover typical pilot plant rooms without additional air conditioning.Typical applicationsLarger batches of up to 25 litres in pilot plant and productionStirring thick samples of up to 30,000 mPasTemperature-controlled processes with PT1000 monitoringDocumented stirring protocols via labworldsoftMedium-sized batches for which neither the 20 nor the 80 model hits the right power classBatches with changing viscosity, where the torque trend on the display gives a first indicationSelection guide: the MICROSTAR/MINISTAR series at a glanceTwelve models make up the IKA MICROSTAR and MINISTAR series, six in the control version and six in the identically constructed digital version.
