Product information "IKA MultiDrive MI 250 T S grinding chamber with temperature sensor, sealed, 250 ml, 0020112098"
Thermodynamic control for highly sensitive dry milling
In demanding materials research, toxicological analysis and pharmaceutical quality control, the dry grinding of hard, brittle or fibrous samples constitutes a physical stress test for the sample material. The conversion of kinetic rotational energy into mechanical comminution work (impact and shear forces) inevitably generates significant frictional heat within the grinding chamber. For thermolabile analytes – such as volatile organic compounds (VOCs), temperature-sensitive vitamins or active pharmaceutical ingredients (APIs) – this uncontrolled rise in temperature is disastrous and leads to irreversible denaturation or outgassing. To completely eliminate this source of methodological error, IKA has developed the highly specialised MultiDrive MI 250 T S grinding chamber. The ‘T’ in the model name stands for the integrated temperature sensor. This high-tech chamber, with a capacity of 250 ml, transforms your mill into a process-monitored, analytically highly reliable grinding system.
Wireless RFID technology for seamless temperature monitoring
The technological heart of the MI 250 T S is the seamless, intelligent communication between the stainless-steel grinding vessel and the drive unit. A high-precision temperature sensor is built into the solid base of the vessel, continuously measuring the thermal stress on the sample in real time during the high-speed grinding process. Data transmission to the essential IKA MultiDrive control mill takes place entirely contactlessly via state-of-the-art RFID (Radio-Frequency Identification) technology. This physical design is fundamental, as it completely eliminates error-prone sliding contacts or mechanical connectors that could corrode during rinsing. You can set a strict, sample-specific temperature limit via the drive’s display. As soon as the critical thermal threshold is reached, the electronics intervene proactively and either stop the drive or reduce the speed, long before any thermal damage can occur to your valuable sample.
Integrated containment: The ‘S’ stands for ‘Sealed’
In addition to temperature monitoring, the vessel resolves the biggest health and safety issue associated with dry milling: aerosol formation. The abbreviation “S” (Sealed) denotes the chamber’s innovative sealing and pressure-equalisation system. When extremely fine dusts are generated or samples are ground with the addition of dry ice (cryogenic grinding), massive overpressure builds up inside the vessel. In particular, the sublimation of solid CO₂ into gas causes the volume to increase abruptly. Without pressure relief, the vessel would leak or burst. The MI 250 T S features an intelligent pressure-equalising valve in the lid, combined with a special microporous foam barrier. This barrier retains 100 per cent of the microfine, often toxic sample material within the vessel (containment), whilst allowing the excess gas pressure to escape safely. This protects laboratory staff from hazardous dusts and simultaneously prevents quantitative loss of the analyte.
Powerful impact grinding and dual cooling options
Despite its sophisticated sensor technology, the MI 250 T S is a robust powerhouse based on the highly efficient impact principle (impact grinding). A solid beater made of extremely wear-resistant stainless steel (1.4034) effortlessly pulverises feed materials at high speed, with a particle size of up to 7 mm and a hardness of 5 on the Mohs scale. To keep the temperature as low as physically possible before the sensor even needs to intervene, the chamber offers two professional cooling methods: it can be actively cooled by circulating cooling water through an external jacket, or it can be filled directly with dry ice inside the chamber. The FDA-compliant, media-contacting surfaces made of stainless steel (1.4301) and chemically resistant silicone ensure absolute purity. For seamless, GLP-compliant (Good Laboratory Practice) decontamination, the crusher can be completely dismantled without the need for tools, which absolutely rules out dangerous cross-contamination (carry-over) during routine analyses.

Customised requirements & accessories
The MI 250 T S only activates its technological safety features when used in conjunction with the premium IKA MultiDrive control drive unit (the ‘basic’ version does not have an RFID receiver and cannot read temperature data). If you require a cutting rather than an impact action for extremely fibrous material (such as cellulose or tough plant fibres), the vessel can easily be fitted with the star knife, which is available as an accessory. Please feel free to contact our highly specialised procurement service at any time for a professional and technically sound configuration of your milling system.
Fits
The all-rounder for the Laboratory 4.0: IKA MultiDrive control The IKA MultiDrive control (MPN 0025002643) is far more than just a mill. It is a technological platform for a wide variety of grinding and mixing tasks. Whether you need to crush hard samples, cut fibrous material or homogenise soft substances – this device adapts to any challenge thanks to its unique interchangeable vessel system. The “control” version stands out from the crowd thanks to intelligent features such as an integrated scale, RFID recognition and a brilliant TFT display, setting new standards in terms of process reliability and ease of use. Versatility thanks to the “MultiDrive” concept The name says it all: one drive (“Drive”) for countless applications (“Multi”). The separately available vessels transform the unit in a matter of seconds: Grinding beaker (MI 250 / MI 400): For classic dry grinding of hard and brittle materials. Mixing beaker (MT 150): With special blades for soft, fibrous or elastic samples (including wet ones). Dispersion jars (BT 250): Transforms the mill into a disperser for the production of emulsions or suspensions. Tube Mill beaker: Thanks to an adapter, even the tried-and-tested disposable beakers from the Tube Mill can be used. Integrated weighing function: Precision without detours A real highlight of the MultiDrive control is the 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 attached grinding beaker. The display shows the weight precisely. Thanks to the tare function, you can also prepare complex mixtures directly in the beaker without having to remove the vessel. This saves time, reduces cleaning effort and prevents transfer losses of expensive substances. Smart 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 beaker – 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 (ideal for better mixing) or set temperature limits (when used with temperature-sensitive vessels). Temperature measurement and cooling Heat is the enemy of many samples. The MultiDrive control, when used in combination with the appropriate vessels (e.g. MI 250 T or MT 150), offers integrated temperature measurement. The sensor in the beaker transmits the actual temperature wirelessly to the display. You can define a safety shut-off: ‘Stop the process when 40 °C is reached’. This effectively prevents the degradation of heat-sensitive constituents. For even more demanding tasks, the system supports actively cooled grinding beakers (double-walled for water cooling) or the use of dry ice for embrittlement directly in the grinding chamber. Plenty of power: 1,000 watts The brushless motor is maintenance-free and extremely powerful. With a power consumption of 1,000 watts and speeds ranging from 3,000 to 20,000 min⁻¹, it can handle even the toughest materials. Despite this power, the unit starts up quietly and gently on the material thanks to frequency converter technology. Easy cleaning and safety Cleaning is incredibly 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 meets the highest standards: an electronic brake brings the tool to a halt in a flash when the housing is opened. Operation is only possible when the protective housing is closed. Connectivity and documentation The device can be seamlessly integrated into the laboratory IT system via the USB and Bluetooth interfaces. With the labworldsoft ® software (optional), you can create grinding programmes, control the device remotely and comprehensively document all process data (speed, time, temperature, weight).

Kinetic Transformation and System Evolution In the analytical preparation of hard and brittle solids (such as ores, minerals, slag or tablets), the classic IKA M 20 analytical mill has been the physical standard for decades. The IKA MultiDrive basic M20 Successor Package represents the technological and kinematic evolution of this system. At the heart of the package is the brushless, high-performance 1,000-watt drive motor of the MultiDrive basic base station. Coupled with the MI 250 grinding chamber and the stainless-steel beater included in the scope of delivery, the system transforms immense electrical energy into massive mechanical impact pulses. With variable rotational speeds of up to 30,000 revolutions per minute, the beater shatters the crystalline or macromolecular lattice structures of the sample matrix in fractions of a millisecond, resulting in a highly homogeneous, reproducible particle size distribution. Thermodynamic control and exothermic compensation High-speed mechanical comminution inevitably induces significant thermodynamic stress (frictional heat) in the sample medium. In temperature-sensitive matrices, this exothermic reaction can lead to molecular degradation or the evaporation of volatile analytical components. The architecture of the MI 250 grinding chamber is designed to minimise this thermodynamic stress. To proactively compensate for thermal peaks during the grinding process, the system enables direct cryogenic cooling: the user can physically apply dry ice (solid carbon dioxide) directly into the grinding chamber to the sample. The sublimation of CO₂ at -78.5 °C continuously removes the heat generated by the process from the matrix, guaranteeing ice-cold, structure-preserving comminution without the need for external cooling circuits. Metrological reproducibility and interval kinematics For analytically valid results, the grinding process must be absolutely reproducible. The MultiDrive basic control system enables the precise preselection of the drive speed in order to strictly adapt the applied shear forces to the specific Mohs hardness of the sample. Furthermore, the system features an integrated interval control. This pulsating kinematics – the rapid alternation between extreme acceleration and absolute standstill – generates massive hydrodynamic turbulence within the material being ground. This effect prevents the agglomeration of fine dust particles on the chamber walls and continuously forces the entire batch volume (up to 250 ml) back into the primary working area of the grinding tool, thereby physically eliminating dead zones in the flow.

However, the modularity of the MultiDrive platform allows for immediate adaptation to highly specific rheological challenges: for extremely viscous, elastic or fibrous matrices (such as textiles or polymers), we recommend using the MI 250.2 star blade for shear grinding. For iron-free grinding of extremely hard rocks in geochemistry, switching to the MI 250.3 tungsten carbide beater is essential.

MultiDrive control BT Package : Disintegration without cross-contamination – this is achieved with the MultiDrive control Package, which includes autoclavable BT 250 single-use vessels and the required TC 1 protective housing for wet samples. The BT 250 is a single-use vessel featuring a 4-blade agitator and flow breakers. The plastic mixing beaker is autoclavable. This effectively prevents cross-contamination, even with repeated use. An integrated RFID chip simultaneously records and limits the service life of the mixing beaker. The scope of delivery includes 5 replacement seals. Replacing the seal extends the service life of the mixing vessel. The disposable vessel can only be operated with the TC 1 protective housing, which is also included in the scope of delivery. Thanks to a wide range of vessels, the MultiDrive control universal shredder handles a wide variety of shredding tasks, from pre-shredding to fine shredding. A USB interface is provided for convenient control and documentation. High performance: Combined with a variable speed range of 3,000 rpm to 20,000 rpm, the 1,000-watt power output guarantees excellent grinding performance. Interval operation: The interval programming function can be easily activated at the touch of a button. Interval operation is particularly advantageous for the pre-shredding of hard samples or for extra-thorough mixing . Integrated cooling A cooling system is integrated into the grinding jar, enabling indirect heat dissipation . This ensures that the ground material and the coolant remain separate. TFT display A clear TFT display ensures user-friendly operation. Temperature measurement MultiDrive control offers temperature measurement and vessel recognition via RFID. A temperature limit can be set for temperature-sensitive materials or specific intended reactions to protect against overheating. Weighing function The weighing function is also integrated into the convenient workflow of the IKA MultiDrive control. Weighing prior to grinding is carried out using the same mixing beaker, so that no decanting is required.

Grinding, weighing, mixing – all in a single step: IKA MultiDrive control MT Package The IKA MultiDrive control MT Package (MPN 0010007083) redefines what a laboratory mill can achieve. In modern analytical work, time savings, reproducibility and freedom from contamination are the most important factors. This high-end system delivers on all three fronts. It is the world’s first universal mill to combine coarse and fine grinding tasks with an integrated weighing function and intelligent RFID technology. The “MT Package” comes complete with the reusable MT 150 stainless steel grinding beaker and the necessary safety accessories, enabling you to work sustainably and cost-effectively. The revolution: integrated weighing function Forget the cumbersome process of separate weighing: placing the weighing pan on the balance, taring, weighing the sample, transferring the sample to the mill (spilling powder in the process), then starting the mill. With the MultiDrive control, you weigh directly into the grinding beaker! The unit features an integrated balance that displays the weight of your sample directly on the user-friendly TFT display. This offers massive advantages: No transfer loss: As you don’t need to transfer the sample, not a single milligram is lost – essential for expensive or potent active ingredients. Time savings: The workflow is significantly streamlined. Convenience: You can even create mixtures by weighing different components into the beaker one after the other (tare function). The MT concept: sustainability and hygiene The MT 150 grinding beaker is included in the scope of delivery. This is a high-quality stainless steel beaker with a hardened impact blade, designed for reusable use. Autoclavable: The entire beaker can be sterilised in an autoclave. This is a ‘must’ for microbiological, pharmaceutical or molecular biology applications where sterility must be guaranteed. Robust: Stainless steel and special-grade plastic withstand even the toughest conditions. Easy to clean: The beaker can be easily dismantled to prevent cross-contamination between different batches through thorough cleaning. Power meets intelligence (RFID) The brushless motor delivers a full 1,000 watts and accelerates the blade to up to 20,000 rpm. This allows you to grind hard, soft or fibrous samples (e.g. wood, tablets, meat, cereals) in seconds. The highlight, however, is the RFID-based vessel recognition: the base unit automatically detects which beaker has been fitted (e.g. the supplied MT 150 or the optionally available disposable beakers). The unit automatically adjusts the speed limits and safety settings to match the detected beaker. This virtually eliminates the risk of operating errors and protects both the user and the equipment. Smart control via TFT display Operation is via a crystal-clear TFT display with intuitive menu navigation. Here you have access to professional functions: Interval operation: Ideal for heat-sensitive samples. The mill pauses at defined intervals to allow the sample to cool and the ground material to settle. Temperature monitoring: (When used with optional temperature-sensing beakers), the instrument can monitor process heat and stop in the event of overheating. Programmable sequences: Save your grinding parameters to ensure strict adherence to Standard Operating Procedures (SOPs). Safety and versatility Safety is a top priority at IKA. The mill only starts if the beaker is correctly closed and the protective housing (TC 1, included in the scope of delivery) is in place. A motor brake stops the blade immediately upon opening. Another advantage is versatility: although this package includes the reusable beaker, the drive is compatible with IKA disposable beakers (Tube Mill System). So, if you ever have toxic samples where cleaning would be too dangerous, simply purchase a set of disposable beakers and use the same drive. “One Drive – Many Possibilities”.
