Product information "IKA MultiDrive MI 250 S grinding chamber, sealed, 250 ml, dry grinding, 0020112097"
Dry grinding with pressure equalisation: the IKA MultiDrive MI 250 S grinding chamber
In modern laboratory analysis, the stringent quality control of food and animal feed, and materials research, the precise and loss-free preparation of samples from dry, hard or brittle materials is a core process engineering task. When raw materials such as fibrous wood, compact animal feed, frozen agricultural products or tough plastic pellets need to be ground, conventional open mills often reach their physical limits. When grinding extremely fine dusts or deep-frozen samples, excess pressure inevitably builds up inside the grinding vessel during the high-speed process. Without a professional seal, the finest sample material would escape uncontrollably into the laboratory environment, which not only leads to distorted analysis results due to sample loss but also poses a significant health risk (dust exposure) to laboratory staff. To solve this highly critical problem in dry milling elegantly, cleanly and safely, IKA has developed the highly specialised MultiDrive MI 250 S grinding chamber (MPN 0020112097). This robust, specially sealed grinding vessel significantly expands the analytical capabilities of your IKA MultiDrive universal mill and supports a low-dust, safe and reproducible batch process, even with fine powders.
The innovative sealing and pressure equalisation system
The outstanding, eponymous technological feature of the MI 250 S (the ‘S’ stands for Sealed) is its sealing and pressure-equalisation system. Unlike simple, inflexible grinding cups, this 250-millilitre vessel is fitted with a special seal. For example, when grinding brittle, frozen samples and the trapped gas expands significantly due to the inevitable grinding friction, this sealing system allows for controlled pressure relief directly via the lid. A special foam integrated into the system acts as a highly effective mechanical barrier. It retains the actual, fine powdered sample material securely and with little loss inside the grinding chamber, whilst allowing the excess air pressure to escape in a controlled manner. This system is useful for laboratories that handle extremely fine, volatile or toxic powders and must ensure reliable containment of their valuable sample material for subsequent analysis.
Grinding and versatile cooling options
Despite its sophisticated, precision sealing technology, the IKA MultiDrive MI 250 S is a robust grinding chamber designed for heavy-duty grinding. A powerful beater made from hard and wear-resistant grade 1.4034 stainless steel is included as standard. This high-speed rotating beater effortlessly pulverises samples with a feed particle size of up to 7 millimetres and a demanding maximum material hardness of 5 on the Mohs scale. To effectively control the inevitable frictional heat generated during heavy-duty grinding processes, which could destroy sensitive analytes, the chamber offers two excellent cooling options: On the one hand, the grinding chamber can be actively cooled from the outside using water. On the other hand, the vessel is suitable for cooling the material directly inside the chamber by adding dry ice (solid CO₂) (cryogenic grinding). When cooling with dry ice, follow the notes in the IKA operating instructions. This can be useful for temperature-sensitive plastics or frozen tissue, which can melt or clump together in the shear gap at room temperature.
Material quality and cleaning
In regulated sectors such as food analysis or stringent pharmaceutical quality control, the requirements regarding material quality and the prevention of cross-contamination (carry-over) are extremely high. The surfaces of the MI 250 S grinding chamber that come into contact with the medium are therefore made of high-quality, easy-to-clean grade 1.4301 stainless steel, sensibly complemented by robust silicone sealing elements. According to the manufacturer, the material concept is designed to be FDA-compliant (Food and Drug Administration). Furthermore, according to IKA, the robust chamber is designed for the processing of abrasive substances. According to IKA, the grinding chamber is cleaned manually. However, to make this process as safe, ergonomic and thorough as possible, the stainless steel beater can be completely dismantled in just a few simple steps. This allows you to ensure at all times that no hidden powder residues or hazardous biofilms accumulate beneath the beater, thereby supporting your laboratory routine.
System integration and optimisation of the Total Cost of Ownership (TCO)
As an original accessory, the MI 250 S grinding chamber is perfectly matched to the IKA MultiDrive basic drive unit (and MultiDrive control). With extremely compact dimensions of 160 x 180 x 160 mm and a weight of just 1.5 kg, the 250-ml vessel is highly ergonomic to handle and can be stored in a space-saving manner in a laboratory cabinet. By purchasing this highly specialised, sealed grinding vessel, you will greatly expand the range of applications for your existing mill. This can make investment in additional specialised mills for very fine powders or powders that need cooling unnecessary. If you require dust protection, material retention and temperature control for your demanding dry grinding of wood, plastics or animal feed, the IKA MultiDrive MI 250 S is a suitable solution for your day-to-day laboratory work.

IKA MultiDrive control: drive unit for grinding, mixing and dispersing The IKA MultiDrive control (MPN 0025002643) is a drive for grinding and mixing tasks. Whether you need to crush hard samples, cut fibrous material or homogenise soft substances, this device can be adapted to the task at hand thanks to its interchangeable vessel system. The “control” version offers an integrated scale, RFID recognition and a TFT display. Versatility thanks to the “MultiDrive” concept The name says it all: one drive (“Drive”) for many applications (“Multi”). The separately available vessels transform the unit depending on the task: Grinding chamber (MI 250 / MI 400): For classic dry grinding of hard and brittle materials. Grinding cup (MT 150): Autoclavable plastic grinding cup, 150 ml. Mixing cup (BT 250): Autoclavable plastic mixing cup, 250 ml. Mixing vessel (BL): For wet grinding. Dispersing vessel (DI): With rotor-stator system for dispersing. Tube Mill cup: Thanks to an adapter, even the tried-and-tested disposable cups of the Tube Mill can be used. Integrated weighing function: Precision without detours The MultiDrive control has an integrated scale. In conventional workflows, samples must be weighed, transferred and then ground separately. This often results in material loss or contamination. With the MultiDrive control, you weigh directly into the fitted grinding cup. The display shows the weight. Thanks to the tare function, you can also prepare complex mixtures directly in the beaker without having to remove the vessel. This can save time and cleaning effort and reduces transfer losses of expensive substances. Process control with RFID and TFT In modern laboratories, error prevention is crucial. Thanks to the integrated RFID technology, the base unit automatically recognises which vessel has been fitted. The system then adjusts the parameters accordingly: Speed limit: A dispersion vessel must not rotate as fast as a grinding cup. The device regulates this automatically. Safety functions: Specific settings are enabled. The large, easy-to-read TFT display allows for intuitive navigation. Here, you can not only set the speed and time, but also activate interval operation (for better mixing) or set temperature limits (when used with temperature-sensitive vessels). Temperature measurement and cooling The MultiDrive control, when used in combination with the appropriate vessels (e.g. MI 250-T-S), offers integrated temperature measurement. The sensor in the cup transmits the actual temperature wirelessly to the display. You can define a safety shut-off: ‘Stop the process when 40 °C is reached’. This helps to limit the degradation of heat-sensitive constituents. For even more demanding tasks, the system supports actively coolable grinding cups (double-walled for water cooling) or the use of dry ice for embrittlement directly in the grinding chamber. Motor: 1,000 watts The motor is brushless. With a power consumption of 1,000 watts and speeds ranging from 3,000 to 20,000 rpm, it can also process hard materials. Despite this power, the unit starts up smoothly thanks to frequency converter technology. Easy cleaning and safety Cleaning is simple, as the unit itself (‘Easy Clean Design’) has virtually no nooks where dirt can accumulate, and the grinding cups (available separately) can usually be completely dismantled and are either dishwasher-safe or autoclavable. In terms of safety, the unit is fitted with an electronic brake that stops the tool when the housing is opened. Operation is only possible when the protective housing is closed. Connectivity and documentation The device can be integrated into the laboratory IT system via the USB and Bluetooth interfaces. With the labworldsoft® software (optional), you can create grinding programs, control the device remotely and document all process data (speed, time, temperature, weight).

For many years, the IKA M 20 batch mill was the standard piece of equipment for the dry grinding of hard and brittle samples, featuring a fixed grinding chamber and a constant speed of 20,000 rpm. The IKA MultiDrive basic M20 Successor Package replaces it and separates the drive from the grinding chamber: The MultiDrive basic drive operates at a variable speed of up to 20,000 rpm, whilst the supplied MI 250-S grinding chamber, with a 250 ml capacity and a stainless steel beater, can be swapped for other chambers from the MultiDrive range if required. IKA explicitly positions the package as the successor product to the M 20.Successor to the M 20, now with an interchangeable chamberWhereas the M 20 was limited to a permanently integrated grinding chamber, the MultiDrive drive system makes the vessel an interchangeable component. The supplied MI 250-S processes hard and brittle substances up to 250 ml dry; an integrated cooling system in the grinding beaker enables indirect heat dissipation during the grinding process, and dry ice can also be used for cooling if the sample is particularly heat-sensitive. For other sample volumes or types, further grinding chambers, mixing and dispersing vessels are available from the MultiDrive range; these are not included in the scope of delivery for this package and must be ordered separately.Basic configuration without TFT and weighing functionUnlike the ‘control’ version of the MultiDrive platform, this package features a 7-segment LED display instead of a TFT display, and does not include an integrated weighing function, temperature measurement or a WPAN interface. Vessel recognition is included, and a micro-USB interface connects the unit to a computer for documentation purposes. With a power consumption of 1,000 watts and a speed range of 3,000 to 20,000 rpm, the grinding performance remains identical to that of the control range; an intermittent operation mode for pre-grinding hard samples or particularly thorough mixing is also available. For laboratories that rely primarily on grinding performance rather than weighing or temperature data, the ‘basic’ configuration streamlines operation to the essentials.Typical applicationsThis package is aimed at laboratories seeking a robust, variably adjustable batch mill for routine analysis, without requiring the additional functions of the control range.Dry grinding of hard and brittle substances up to 250 mlReplacement for the IKA M 20 batch millGrinding of soft or fibrous samples in day-to-day laboratory workApplications involving varying sample volumes thanks to the interchangeable grinding chamberConversion to wet or fine grinding by changing the vesselsTechnical detailsMotor power input / output1,000 W / 800 WSpeed range3,000 to 20,000 rpm, deviation ±5 %Display7-segment LEDVessel detectionYesOn/off cycle time5 min / 10 minInterfaceMicro-USBPermissible ambient conditions5 to 40 °C, max. 80 % relative humidityConnected load specifications220 to 240 V, 50/60 Hz, 1,000 W (230 V / 100 to 120 V / 100 V variants available)Degree of protectionIP 31 (DIN EN 60529)Dimensions W x H x D300 x 350 x 250 mmWeight8.5 kgScope of delivery1 x IKA MultiDrive basic drive unit1 x MultiDrive MI 250-S grinding chamber, 250 ml, with standard stainless steel beaterAt the end of its useful life, this electrical appliance belongs in the separate collection scheme for waste electrical and electronic equipment (WEEE) and not in household waste.Regulatory informationThis device is an electrical appliance within the meaning of the German Electrical and Electronic Equipment Act (ElektroG). The WEEE registration number of the manufacturer, IKA, is DE 66784213. Information on the return of old appliances can be found on our page Environment and disposal.Individual requirements and procurement serviceIf a suitable grinding chamber is already available, the IKA MultiDrive basic drive unit alone (without a vessel) is also sufficient. Those who also require an integrated weighing function, temperature measurement and a TFT display will find these features in the control packages: the MultiDrive control BT Package for wet samples and the MultiDrive control MT Package for dry samples. The previous model, the IKA M 20, is also available. Further grinding chambers and accessories for IKA mills can be requested via our procurement service. IKA provides a 2-year manufacturer’s warranty on the drive unit, which is extended to 3 years upon registration at ika.com/register within 90 days of purchase.Frequently asked questionsIs this package identical in design to the M 20?No, the M 20 has a permanently fitted grinding chamber; here, the MI-250-S chamber is an interchangeable part mounted on a separate MultiDrive drive.Does the drive have a weighing function?No, this ‘basic’ version has neither a weighing function nor a TFT display; the ‘control’ packages are available for these features.Can the ground material be cooled?Yes, the MI 250-S grinding chamber has an integrated cooling system and can also be cooled with dry ice.How long is the warranty valid for?IKA provides a 2-year manufacturer’s warranty on the drive; this is extended to 3 years if the unit is registered at ika.com/register within 90 days of purchase.What is the drive power of this package compared to the M 20?The MultiDrive drive has a power consumption of 1,000 watts and a speed range of 3,000 to 20,000 rpm, thereby fully covering the previous fixed speed of the M 20, whilst also being variably adjustable.
To grind wet, moist or pasty samples with less carry-over of residues in the grinding tool from one batch to the next: this is what the IKA MultiDrive control BT Package is designed for. The package combines the MultiDrive control drive, featuring a TFT display and integrated weighing function, with the autoclavable single-use BT 250 vessel, which is fitted with a four-blade cross-beater and flow breaker. An RFID chip in the base of the vessel automatically records and limits its service life, ensuring that each grinding run is confined to a fresh vessel; this prevents any subsequent reuse beyond the intended service life.BT 250: Disposable vessel for wet samplesThe BT 250.5 mixing beaker is made of autoclavable plastic and is operated exclusively in conjunction with the supplied TC 1 protective housing, which serves safety during grinding. Five replacement seals are included to ensure that a vessel remains leak-proof over several uses before a new one needs to be ordered. The standardised mounting allows additional vessels from the MultiDrive range to be used, such as grinding chambers for dry material or dispersion vessels with temperature measurement; however, these are not included in the Scope of delivery of this package.Weighing function, TFT display and temperature measurementThe mixing beaker can be weighed directly on the drive; a weighing range of 5 to 4,000 g with a resolution of 1 g covers most laboratory balances without the need to transfer the sample. Temperature measurement from -50 to 120 °C with an accuracy of ±1 K monitors the material being ground during operation. The TFT display clearly shows all values; a WPAN interface and a micro-USB socket connect the unit to a computer for documentation and remote control. With a power consumption of 1,000 watts and a speed range of 3,000 to 20,000 rpm, the drive is designed for coarse to fine grinding; intermittent operation can be activated via a button.Typical applicationsThe BT Package is suitable for laboratories that regularly process different moist sample matrices and want to avoid carry-over between batches.Grinding of moist, wet or pasty samples with reduced cross-contaminationWeighing and grinding in the same vessel, without the need for decantingTemperature-monitored homogenisation of sensitive samplesCoarse to fine grinding with variable speed up to 20,000 rpmTechnical detailsMotor power input / output1,000 W / 800 WSpeed range3,000 to 20,000 rpm, deviation ±5 %DisplayTFT, with RFID read/write unitWeighing range5 to 4,000 g, resolution 1 g, accuracy ±(0.3 % + 2) gTemperature measurement-50 to 120 °C, resolution 0.1 K, accuracy ±1 KDuty cycle ON / OFF5 min / 10 minInterfacesMicro-USB, WPANPermissible ambient conditions5 to 40 °C, max. 80 % relative humidityConnected load220 to 240 V, 50/60 Hz, 1,000 W (100 to 120 V / 100 to 115 V variants available)IP ratingIP 31 (DIN EN 60529)Dimensions W x H x D300 x 350 x 250 mmWeight8.5 kgScope of delivery1 x IKA MultiDrive control drive unit1 x MultiDrive TC 1 protective housing for MT 150 and BT 2501 x MultiDrive BT 250.5 mixing beaker, autoclavable5 x replacement seals for the mixing beakerAt the end of its service life, this electrical appliance must be disposed of via the separate collection scheme for waste electrical and electronic equipment (WEEE) and must not be placed in household waste.Regulatory informationThis device is an electrical appliance within the meaning of the German Electrical and Electronic Equipment Act (ElektroG).

The drive unit is identical in both cases.How long is the warranty valid for?IKA provides a 2-year manufacturer’s warranty on the drive; this is extended to 3 years if the product is registered at ika.com/register within 90 days of purchase.
A single fixed-speed batch mill rarely covers all the grinding tasks required in a laboratory. The IKA MultiDrive basic therefore separates the drive unit from the vessel: a 1,000-watt drive unit with a variable speed range of 3,000 to 20,000 rpm, to which different grinding chambers or mixing vessels can be connected depending on the task.Variable speed from 3,000 to 20,000 rpmThe brushless DC motor draws 1,000 W and delivers 800 W, with a speed deviation of ±5 %. An intermittent operation mode, which can be activated at the touch of a button, allows hard samples to be pre-ground or mixed particularly thoroughly. The operating principle encompasses cutting, impact crushing, mixing and dispersing; an automatic vessel detection system adjusts the drive to suit the connected vessel.Vessels can be selected separatelyThe drive unit itself does not include a grinding chamber or mixing vessel. The sealed MI 250-S and MI 400-S grinding chambers are available for dry grinding, whilst the BL 2000 mixing vessel is available for wet grinding and mixing. The MI grinding chambers can be cooled indirectly using the CS 1 cooling system, whilst keeping the material being ground and the coolant separate. The combination of vessel and beater best suited to a particular sample depends on the hardness of the material and the desired final particle size.Connection and environmental conditionsOperation is indicated via a 7-segment LED display, whilst a micro-USB interface is used to connect to PC software. The permissible ambient temperature range is 5 to 40 °C, and the permissible relative humidity is 80 %. Measuring 300 x 350 x 250 mm and weighing 8.5 kg, the MultiDrive basic is slightly larger and heavier than the M 20, but offers significantly greater flexibility in terms of speed. The unit’s power consumption is 1,000 W at 220 to 240 V, and it has an IP 31 protection rating in accordance with DIN EN 60529.Beaters, blades and qualificationThe MI 250-S and MI 400-S grinding chambers each come with their own beaters and blades made of stainless steel or tungsten carbide (MI 250.1/.2/.3 and MI 400.1/.2/.3), whilst the BL 2000 mixing vessel comes with the standard BL 2000.1 mixing blade. Tungsten carbide is recommended for particularly abrasive or hard samples, where a stainless steel beater would wear out more quickly. For regulated environments, IKA provides factory calibration certificates and IQ/OQ documents for the MultiDrive basic.One drive for multiple batch sizesAs the MI 250-S, MI 400-S and BL 2000 are connected to the same drive, a single MultiDrive basic can be used to process both a small 250-ml batch and a larger 400-ml or 2000-ml batch without the need to purchase a second unit. Automatic vessel recognition ensures that the drive detects which vessel is connected and adjusts the parameters accordingly. For vessels with their own temperature sensor (MI 250-T-S, MI 400-T-S, DI 2000-T), the drive also displays the medium temperature, which is helpful for temperature-sensitive samples.Certificates for regulated establishmentsIn addition to the IQ/OQ documents, IKA also provides general certificates 2.2 and 3.1 for the MultiDrive basic, as well as guidance on carrying out the qualification process. For organisations with documented equipment qualifications, for example, in pharmaceutical development, these documents can be incorporated directly into their own quality management documentation, together with the factory calibration certificate.Typical applicationsGrinding of hard, soft or fibrous samples using a single driveTasks that involve both grinding and mixing or dispersingPreliminary comminution in intermittent operation for particularly tough samplesLaboratories that wish to accommodate different batch sizes by using different vesselsTechnical detailsProcess typeBatchOperating principleCutting / Impact crushing / Mixing / DispersingMotor power input / output1,000 W / 800 WSpeed range3,000 to 20,000 rpmSpeed deviation±5 %Motor principlebrushless, direct currentVessel detectionyesPermissible ambient temperature / relative humidity5 to 40 °C / 80 %USB interfaceMicro-USBDimensions (W x H x D)300 × 350 × 250 mmWeight8.5 kgConnected load220 to 240 V, 50/60 Hz, 1,000 W (other voltage options available)Degree of protectionIP 31 (DIN EN 60529)Scope of delivery1 x IKA MultiDrive basic (drive unit)1 x socket spanner2 x disassembly tools1 x cleaning brush1 x USB cable, USB A to Micro-B, 2 mGrinding chambers and mixing vessels are separate accessories and are not included in the scope of delivery for the drive.Regulatory informationThis device is an electrical appliance within the meaning of the German Electrical and Electronic Equipment Act (ElektroG).

Grinding dry samples whilst directly determining the initial weight using the same vessel: this is what the IKA MultiDrive control MT Package is designed for. The package combines the MultiDrive control drive, featuring a TFT display and integrated weighing function, with the autoclavable disposable MT 150 vessel, which comes with a classic stainless steel beater for dry materials. An RFID chip in the base of the vessel automatically records and limits its service life.MT 150: Disposable vessel for dry samplesThe MT 150.5 grinding vessel is made of autoclavable plastic and is operated exclusively in conjunction with the supplied TC 1 protective housing, which serves safety during grinding. Five replacement seals are included to ensure that a vessel remains leak-proof over several uses before a new one needs to be ordered. The standardised mounting allows additional vessels from the MultiDrive range to be used, such as grinding chambers for other sample volumes or the autoclavable BT 250 for wet samples; however, these are not included in the Scope of delivery of this package.Weighing function, TFT display and temperature measurementThe grinding vessel can be weighed directly on the drive; a weighing range of 5 to 4,000 g with a resolution of 1 g covers most laboratory weighing requirements without the need to transfer the sample. Temperature measurement from -50 to 120 °C, with an accuracy of ±1 K, monitors the ground material during operation. The TFT display clearly shows all values; a WPAN interface and a micro-USB socket connect the device to a computer for documentation and remote control. With a power consumption of 1,000 watts and a speed range of 3,000 to 20,000 rpm, the drive is designed for coarse to fine grinding; intermittent operation can be activated via a button.Typical applicationsThe MT Package is suitable for laboratories that regularly grind dry or fibrous sample material and wish to carry out both weighing and grinding in the same vessel.Grinding of dry and fibrous samples with reduced cross-contaminationWeighing and grinding in the same vessel, without the need for transferTemperature-controlled grinding of sensitive dry samplesCoarse to fine grinding with variable speed up to 20,000 rpmTechnical detailsMotor power input / output1,000 W / 800 WSpeed range3,000 to 20,000 rpm, deviation ±5 %DisplayTFT, with RFID read/write unitWeighing range5 to 4,000 g, resolution 1 g, accuracy ±(0.3 % + 2) gTemperature measurement-50 to 120 °C, resolution 0.1 K, accuracy ±1 KDuty cycle ON / OFF5 min / 10 minInterfacesMicro-USB, WPANPermissible ambient conditions5 to 40 °C, max. 80 % relative humidityConnected load220 to 240 V, 50/60 Hz, 1,000 W (100 to 120 V / 100 to 115 V variants available)IP ratingIP 31 (DIN EN 60529)Dimensions W x H x D300 x 350 x 250 mmWeight8.5 kgScope of delivery1 x IKA MultiDrive control drive unit1 x MultiDrive TC 1 protective housing for MT 150 and BT 2501 x MultiDrive MT 150.5 grinding vessel, autoclavable5 x replacement seals for the grinding vesselAt the end of its service life, this electrical appliance must be disposed of via the separate collection scheme for waste electrical and electronic equipment and must not be placed in household waste.Regulatory informationThis device is an electrical appliance within the meaning of the German Electrical and Electronic Equipment Act (ElektroG).
