IKA MultiDrive control Universal Mill, drive unit with scales & RFID, 0025002643

Uncompromising temperature control during wet grinding: the IKA MultiDrive BL 2000 T mixing vessel In demanding food analysis, biological research and pharmaceutical quality control, the comminution of moist, fatty or fibrous samples (wet grinding) is a fundamental standard process. However, when processing these tough matrices in high-performance mills, the enormous shear forces inevitably generate significant frictional heat. For samples that are highly sensitive to temperature, such as fresh meat, enzyme-containing plant tissue or vitamin-rich vegetables, this uncontrolled rise in temperature is an absolute deal-breaker. Heat leads to the irreversible denaturation of proteins, the destruction of volatile flavour compounds and the fatal distortion of heat-labile analytes. It is precisely for these highly critical, temperature-sensitive applications that IKA has developed the sophisticated MultiDrive BL 2000 T mixing vessel (MPN 0025003962). The crucial ‘T’ in the product name stands for the integrated temperature sensor. This smart 2-litre mixing vessel, designed as a blender, transforms your IKA MultiDrive universal mill not only into a powerful wet grinder, but also into a fully monitored, analytically reliable high-performance system. The innovation: integrated sensor and RFID data transmission The technological heart of the BL 2000 T is the seamless, intelligent communication between the mixing vessel and the drive unit. A high-precision temperature sensor is permanently integrated into the base of the vessel, measuring the exact thermal load on your sample in real time throughout the entire grinding process. Data is transmitted from the rotating vessel to the mill entirely wirelessly via state-of-the-art RFID (Radio-Frequency Identification) technology. This design is truly groundbreaking, as it completely eliminates the need for cumbersome, wear-prone plug connections or error-prone sliding contacts, which could be damaged during rinsing. If you use this vessel in conjunction with the IKA MultiDrive control premium drive, you can set a customised, strict temperature limit via the mill’s display. According to IKA, a temperature limit can be set to protect against overheating. Impressive performance for demanding sample matrices In addition to its excellent temperature monitoring, the BL 2000 T impresses with its sheer mechanical grinding power during wet grinding. According to the manufacturer’s specifications, the vessel is ideally suited to an extremely wide variety of challenging raw materials: It effortlessly grinds sinewy meat and fatty sausages for food safety testing, pulverises hard soya beans for nitrogen determination, processes extremely tough, moist silage for agricultural feed analysis, and purées fresh vegetables for residue analysis. A solid standard blend knife made from high-quality, corrosion-resistant stainless steel (1.4034) is included as standard. This razor-sharp tool, with a diameter of 75 mm, effortlessly penetrates thick cell walls at extremely high circumferential speeds of up to 78.5 m/s, cuts through muscle fibres and generates powerful hydrodynamic turbulence, guaranteeing absolutely uniform mixing. Volume and time savings: the 2-litre advantage in everyday laboratory work An extremely common problem in analytical work is the lack of representativeness caused by sample sizes that are too small. If only a tiny piece is taken from a large food container, this sample is rarely representative of the entire batch. The IKA MultiDrive BL 2000 T solves this problem thanks to its enormous maximum usable volume of 2,000 millilitres (2 litres). This enormous volume allows you to process large, statistically valid cross-sectional samples in a single, rapid batch process. Another major advantage that makes your work easier is the considerable tolerance for sample feeding: the maximum feed grain size is an impressive 30 millimetres. This means you do not need to spend time pre-cutting your moist samples into tiny fragments with a scalpel beforehand; coarsely crushed chunks can be placed directly into the mixing vessel. This drastically minimises set-up and preparation times in your laboratory and reduces process costs. Hygiene and thorough deep cleaning Where raw meat, biological tissue or high-fat suspensions are handled, the risk of dangerous cross-contamination (carry-over) is ever-present. Even minute traces of protein or DNA from the previous sample remaining in the vessel can completely ruin expensive follow-up analyses. Despite the highly complex RFID and sensor technology in the base, IKA has designed the BL 2000 T vessel to ensure absolute, uncompromising hygiene. The entire vessel, along with all its components that come into contact with the sample, can be cleaned conveniently and safely in the laboratory dishwasher. The key design feature for thorough microbiological cleaning: the sharp stainless-steel mixing blade can be completely dismantled in just a few simple steps. This ensures that absolutely no stubborn biofilms, fats or sample residues can accumulate beneath the blades or on the seals (which are made from high-quality PTFE and silicone). The transparent housing of the BL 2000 T is made from durable PCTG plastic, which allows for constant visual monitoring of the grinding process. With compact dimensions of 180 x 280 x 220 mm and a light weight of just 1.25 kg, the vessel can be handled ergonomically and in a way that is easy on the back. By investing in the IKA MultiDrive BL 2000 T mixing vessel, you can use your mill for wet grinding with temperature monitoring.

Individual requirements & accessories To operate this high-tech vessel and its safety features, you must have the system’s premium core component: the IKA MultiDrive control drive unit (the cheaper ‘basic’ version cannot read the sensor’s RFID signal). If you wish to grind extremely hard or dry materials (such as stones, ceramics or hard cereal grains), we do not recommend this wet grinding vessel. In this case, we recommend the specially developed IKA grinding chambers (MI series) with hard impact blades. The stainless steel mixing blade (BL 2000.1) included can, of course, also be ordered separately as a spare part in the event of heavy wear.

Precise 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 guarantees a dust-free, safe and reproducible batch process, even with extremely 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 completely redesigned sealing and pressure-equalisation system. Unlike simple, inflexible grinding cups, this 250-millilitre vessel is fitted with a highly innovative 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 absolutely securely and without loss inside the grinding chamber, whilst allowing the excess air pressure to escape safely and without risk. This system is invaluable for laboratories that handle extremely fine, volatile or toxic powders and must ensure absolute containment of their valuable sample material for subsequent analysis. Brute grinding power and versatile cooling options Despite its sophisticated, precision sealing technology, the IKA MultiDrive MI 250 S is an uncompromising, robust powerhouse designed for heavy-duty grinding. A powerful beater made from extremely 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). This is an essential technological requirement for processing temperature-sensitive plastics or frozen tissue, which would immediately melt, clump together or undergo chemical denaturation in the shear gap at normal 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 absolute 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, the robust chamber is specifically approved for the processing of highly 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. You will completely eliminate the need for costly investments in additional, expensive specialised mills for extremely fine powders or those requiring strict temperature control. If you require the absolute highest level of 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 the economically (TCO) and analytically perfect solution for your day-to-day laboratory work.

Individual requirements & accessories To operate this sealed grinding vessel, you must have the IKA MultiDrive basic or MultiDrive control drive unit. Depending on the nature of your samples, IKA offers additional, optional tools for this vessel: For extremely hard or fibrous materials, the vessel can be fitted with a special stainless steel star knife or a hard metal beater. Our experienced procurement service will be happy to advise you on selecting the ideal grinding tools and configuring your IKA MultiDrive system.

Maximum safety and capacity for dry grinding: the IKA MultiDrive MI 400 S grinding chamber In industrial materials research, agricultural analysis and the strictly regulated quality control of food and animal feed, the reproducible and absolutely loss-free preparation of samples from dry, hard or brittle materials is a fundamental core task. When tough raw materials such as fibrous wood, compact animal feed, frozen agricultural products or plastics need to be ground, conventional, open grinding vessels often reach their physical and health and safety limits. During the intensive comminution of extremely fine dusts or the processing of deep-frozen samples, the grinding energy and gas expansion inevitably cause a significant build-up of overpressure inside the grinding vessel. Without a professionally engineered seal, the finest sample material would escape uncontrollably into the laboratory environment as an aerosol. This not only leads to massively distorted analytical results due to measurable sample loss, but also poses a significant health hazard (dust exposure) to laboratory staff. To solve this highly critical problem in large-volume dry grinding elegantly and safely, IKA has developed the highly specialised MultiDrive MI 400 S grinding chamber (MPN 0020112099). This robust, specially sealed grinding vessel significantly expands the analytical capabilities of your IKA MultiDrive universal mill and guarantees an absolutely dust-free, safe and highly reproducible batch process on a generous 400 ml scale. The 400-ml volume: the key to representative composite samples The greatest and most decisive advantage of the MI 400 S over smaller models is its exceptionally generous working volume of up to 400 millilitres. In the analysis of heterogeneous natural materials, such as mixed animal feed, bark mulch or shredded plastic waste, an insufficient sample size is often the biggest obstacle to reliable results. A tiny sample simply does not reflect the overall composition of the batch. The IKA MI 400 S enables you to process large, statistically fully representative cross-sectional samples in a single, rapid grinding cycle. With a maximum permissible feed particle size of 7 millimetres, you also drastically minimise set-up and preparation times in your laboratory, as many samples no longer need to be pre-shredded, a time-consuming and error-prone process. Innovative containment: the sealed pressure equalisation system The “S” in the product name unambiguously stands for “Sealed”. The grinding chamber is equipped with a highly innovative, intelligent sealing and pressure-equalisation system. For example, when grinding brittle samples mixed with dry ice, and the trapped gas expands significantly due to the resulting kinetic grinding friction, this system enables controlled pressure relief directly via the chamber lid. A special foam material, integrated into the sealing system, acts as a highly effective mechanical barrier. It retains the fine, often toxic or highly valuable powdered sample material absolutely securely inside the grinding chamber (containment), whilst the excess, hazardous air pressure can be safely and harmlessly released into the environment. Brute grinding power and extreme cooling options The IKA MultiDrive MI 400 S is an uncompromising powerhouse for heavy-duty impact and cutting comminution (impact operating principle). A powerful beater (standard beater) made from extremely hard and wear-resistant grade 1.4034 stainless steel is included as standard. This high-speed rotating beater, with a massive diameter of 81 mm, effortlessly crushes samples with a demanding maximum material hardness of 5 on the Mohs scale at speeds of up to 20,000 rpm. The circumferential speed reaches a staggering 85 m/s. To effectively control the inevitable frictional heat generated during such intensive comminution processes, which would inevitably destroy heat-sensitive analytes, the chamber offers two excellent professional cooling options: the grinding chamber can be actively cooled from the outside via a cooling jacket with circulating water. Even more important for research: the vessel is suitable for deep-freezing the material directly inside the chamber by adding dry ice (solid CO₂) (cryogenic grinding). This is the essential technological prerequisite for the successful processing of tough plastics or frozen natural substances, which would melt immediately at normal room temperature and block the grinding mechanism. Material quality, cleaning and system integration In highly regulated sectors such as food analysis or pharmaceutical quality control, the absolute prevention of cross-contamination (carry-over) is of paramount importance. The surfaces of the MI 400 S grinding chamber that come into contact with the medium are made of high-quality, easy-to-clean grade 1.4301 stainless steel, effectively complemented by robust sealing elements made of chemically resistant silicone. According to the manufacturer, the material concept is designed to be FDA-compliant (Food and Drug Administration). Furthermore, the robust chamber is specifically approved for processing highly abrasive substances. To ensure thorough intensive cleaning, the heavy stainless steel beater can be completely dismantled in just a few simple steps. Weighing just 1.5 kg, this accessory is perfectly matched to the IKA MultiDrive basic and MultiDrive control drive units. If you require the very highest level of dust protection, representative sample quantities and temperature control for your demanding, high-volume dry grinding of wood, plastics or animal feed, the IKA MultiDrive MI 400 S is the perfect solution for your laboratory, both economically and analytically.

Individual requirements & accessories To put this sealed 400 ml grinding vessel into operation, you will need the heart of the system: the IKA MultiDrive basic or MultiDrive control drive unit. Depending on the specific material properties of your samples, IKA also offers high-performance alternative grinding tools for this vessel, such as the special MultiDrive MI 400.2 star knife for extremely fibrous material. Our experienced procurement service will be happy to advise you in detail on selecting the ideal grinding tools and the bespoke configuration of your IKA MultiDrive milling system.

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 % 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 surfaces in contact with media are made of stainless steel (1.4301) and chemically resistant silicone, FDA-compliant according to the manufacturer. For thorough decontamination, the beater can be completely dismantled without the need for tools, which reduces the risk of cross-contamination (carry-over) during routine analyses. Technical details Useful volume: 250 ml Process type & operating principle: Batch operation / Impact (impact milling) Special feature (T=Temperature): Integrated temperature sensor in the base of the vessel Data transmission: Wireless via RFID technology (wear-free) Special feature (S=Sealed): Sealed system with integrated pressure equalisation via the lid Aerosol protection: Special foam insert prevents the escape of fine dust Max. feed particle size: 7 mm Max. feed material hardness: 5 Mohs Compatible drive: IKA MultiDrive control only (essential for using the RFID temperature function) Cooling options: Chamber can be water-cooled externally; interior suitable for direct dry-ice cooling (cryogenic grinding) Material (chamber): High-grade stainless steel 1.4301 Material (beater): Wear-resistant stainless steel 1.4034 Seal material: Silicone FDA compliance of parts in contact with media: according to the manufacturer Cleaning/hygiene: The stainless steel beater can be completely dismantled for intensive cleaning Dimensions (W x H x D): 160 x 180 x 160 mm Weight: 1.5 kg Scope of delivery 1 x IKA MultiDrive MI 250 T S grinding chamber (sealed, with temperature sensor, 250 ml) 1 x standard beater made of 1.4034 stainless steel (already fitted, removable) (Important note: The essential IKA MultiDrive control drive unit is not included in the scope of delivery!) Individual 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.

Digital monitoring and extending the service life of grinding vessels In modern sample preparation, the mechanical integrity of grinding and mixing vessels is a critical safety factor. When autoclavable plastic vessels such as the IKA MultiDrive MT 150.5 or BT 250.5 are operated at extreme speeds of up to 20,000 revolutions per minute, the integrated seals are subjected to immense physical and thermal stress. To prevent unnoticed material wear, leaks or even mechanical failure of the vessels during operation, these special IKA tubes communicate continuously with the drive unit via an integrated RFID chip. The mill records the exact duration of use and, via software, locks the vessel as soon as the seal’s safe service life has been exceeded. It is precisely at this process-critical interface that the IKA MultiDrive TS 1 seal set comes into play. With these five high-precision replacement seals and the essential unlock code, you can transform tubes that have been disabled by the software back into fully operational laboratory tools. The principle of the reactivation code: maximum process reliability The reactivation code included in the scope of delivery is not merely a software feature, but a fundamental component of occupational safety. If you manually replace the mechanically worn seal of an MT 150.5 grinding tube (dry grinding) or a BT 250.5 mixing tube (wet grinding), the IKA MultiDrive control drive unit does not automatically register this physical maintenance step. Only by entering the enclosed unlock code into the system is the internal RFID usage counter for that specific tube reset to zero. This digital handshake guarantees to both the system and the user that a physically new, unused seal has been installed, which will once again withstand the extreme hydrodynamic pressures and shear forces of the next analysis cycle with full reliability. Prevention of cross-contamination and aerosol formation In addition to purely mechanical safety, regular seal replacement plays a key analytical role. Even with the most intensive autoclave cleaning, minute residues of DNA, proteins or toxic analytes from the previous sample can become embedded in the microscopic abrasion of aged sealing rings in the form of stubborn biofilms. By consistently replacing the TS 1 seals, the hermetic seal of the sample is restored and the risk of cross-contamination (carry-over) between different sample batches is reduced. The intact sealing system also protects laboratory staff, as it effectively prevents the escape of fine, respirable aerosols during the vigorous dry grinding of brittle materials. Drastic reduction in the Total Cost of Ownership (TCO) Investing in the TS 1 replacement seal set is a highly cost-effective decision for laboratories with high sample throughput. Instead of disposing of the entire tube, made from high-quality plastics and a solid stainless steel beater, as costly plastic waste once its software-defined service life has expired, you simply replace the specific wear part. This extends the service life of the expensive MT 150.5 and BT 250.5 vessels, reduces your laboratory’s plastic waste and significantly lowers the running costs (Total Cost of Ownership) for the IKA MultiDrive system. Technical details Product type: Replacement seal set with digital reactivation code Compatibility (vessels): Exclusively for IKA MultiDrive MT 150.5 (grinding tube) and BT 250.5 (mixing tube) Compatibility (drive): Specifically designed to interact with the IKA MultiDrive control (for code entry and RFID processing) Operating principle: Resets the tubes’ internal RFID lifetime counter Analytical benefit: Restores the hermetic seal, preventing cross-contamination Mechanical benefit: Prevents the escape of liquids (wet grinding) or dust aerosols (dry grinding) at speeds of up to 20,000 rpm Economic benefit: Significant extension of the service life of expensive grinding vessels (reduction in TCO) Packaging unit: 5 pieces per set Scope of delivery 5 x IKA MultiDrive TS 1 replacement seals (precisely fitted for MT 150.5 and BT 250.5) 1 x physical reactivation code for system reset (Important note: The MT 150.5 and BT 250.5 grinding/mixing vessels, as well as the IKA MultiDrive control drive unit, are not included in the scope of delivery!) Individual requirements & accessories Please note that you only need this item if you are already using the reusable MT 150.5 or BT 250.5 plastic tubes and your drive unit is displaying an expired RFID counter. For extremely hard, brittle or temperature-sensitive samples that cannot be processed in plastic vessels, we recommend switching to the solid stainless steel grinding chambers of the IKA MI series (e.g. MI 250 S), which have no software-imposed service life limit. Our technical procurement service will be happy to advise you on optimising your sample preparation workflows.

Sterile wet homogenisation without cross-contamination In microbiological diagnostics, food analysis and toxicological sample preparation, the sterile homogenisation of moist, fatty or liquid sample matrices is a highly critical process step. The IKA MultiDrive BT 250.5 mixing beakers (blender tubes) are designed specifically for these demanding wet grinding applications. The vessels, made from high-quality, temperature-stable, high-performance plastic, enable closed, aerosol-tight sample processing. The outstanding technical feature of these beakers is that they are fully autoclavable. Following the homogenisation of infectious or highly sensitive samples (such as animal tissue for DNA extraction), the entire tubes can be thermally processed in a steam steriliser at 121 °C and 2 bar gauge pressure. This helps to remove nucleic acids, proteins and pathogenic microorganisms and reduces the risk of cross-contamination (carry-over) in subsequent analysis cycles. Hydrodynamic efficiency thanks to an integrated cross-blade The grinding process inside the 250-ml vessel is carried out by a permanently fitted, highly sharp cross-blade made of corrosion-resistant stainless steel. In contrast to straight impact blades used for dry grinding, the complex geometry of the cross-blade generates massive axial and radial flow fields at speeds of up to 20,000 rpm. These strong hydrodynamic turbulences continuously draw the sample material into the high-shear zone of the blades. Plant fibres, tough muscle tissue or moist agricultural products are cut up within fractions of a second and processed in the carrier fluid into a homogeneous, lump-free suspension. Digital lifecycle tracking via RFID technology During high-speed wet comminution, the mechanical seals of the mixing beaker are subjected to extreme physical stress. Unnoticed wear and tear would lead to liquid leakage and destruction of the drive motor. To eliminate this critical risk, every BT 250.5 mixing beaker is fitted with an integrated RFID chip. In combination with the IKA MultiDrive control drive unit, the vessel communicates wirelessly with the mill. The system monitors the exact rotation time and thermal load of each individual tube. As soon as the seal reaches its manufacturer-validated, safe service life, the software preventively halts further operation. Reducing the Total Cost of Ownership (TCO) through reusability The design as a robust, autoclavable, reusable vessel offers laboratories with high sample throughput a significant economic advantage. Instead of using expensive single-use plastic tubes for every sample and having to dispose of them as contaminated hazardous waste, the BT 250.5 tubes can be reused many times. Once the software-defined service life of the seal has been reached, there is no need to dispose of the entire tube. Simply replacing the bottom seal (using the separately available TS 1 replacement seals, complete with an unlock code) resets the RFID counter, making the tube available for a completely new life cycle. This drastically reduces internal laboratory plastic waste and permanently optimises the Total Cost of Ownership (TCO) of the entire comminution system. Technical details Product type: Reusable mixing beaker (Blender Tube) Maximum usable volume: 250 ml Process type: Batch operation Main application: Wet grinding, mixing and suspending biological samples and foodstuffs Operating principle: Cutting and comminution Integrated tool: Ultra-sharp cross-blade Blade material: Wear-resistant stainless steel Vessel material: High-temperature-resistant, autoclavable and partially transparent plastic Sterilisation: Fully autoclavable (thermal decontamination at 121 °C) Safety / Tracking: Integrated RFID chip for seamless lifetime monitoring Compatible drives: IKA MultiDrive basic (without tracking function) and MultiDrive control (full RFID functionality) Maintenance / Repair: Replaceable base seal (reset possible via IKA TS 1 unlock code) Packaging unit (PU): 5 pieces per set Scope of delivery 5 x IKA MultiDrive BT 250.5 mixing beakers (250 ml, incl. cross blade and RFID chip) (Important note: The essential IKA MultiDrive drive unit is not included in the scope of delivery!) Individual requirements & accessories If you wish to take full advantage of the safety offered by digital service life monitoring, the use of the IKA MultiDrive control drive unit is essential. To avoid having to dispose of the tubes once the RFID cycles have expired, we advise you to add the IKA TS 1 replacement seal set (MPN 0020023490) to your laboratory stock in good time. If you need to grind extremely hard, dusty samples without adding liquid, please switch to the dedicated grinding tubes from the MT series. Our procurement service is always on hand to assist you in selecting the process-specific grinding vessels.

Thermodynamic process control for large-volume dry grinding In demanding materials research, the toxicological analysis of heterogeneous substances and agricultural quality control, the large-volume dry grinding of hard or brittle sample matrices poses a significant physical challenge. The conversion of kinetic rotational energy into mechanical grinding work inevitably generates extreme frictional heat within the grinding chamber. For thermolabile analytes such as volatile organic compounds (VOCs) or active pharmaceutical ingredients (APIs), this uncontrolled rise in temperature leads to irreversible denaturation. To completely eliminate this source of methodological error on a 400-millilitre scale, IKA has developed the highly specialised MultiDrive MI 400 T S grinding chamber. The “T” denotes the integrated temperature sensor. This generously dimensioned, high-tech chamber transforms your mill into a process-monitored, analytically highly reliable grinding system for representative average samples. Wireless RFID technology for seamless temperature monitoring The technological heart of the MI 400 T S is the seamless and intelligent communication between the solid stainless-steel grinding vessel and the drive unit. A high-precision temperature sensor is built into the solid base of the 400-ml vessel, continuously measuring the exact thermal load on the sample during the high-speed grinding process. Data is transmitted to the essential IKA MultiDrive control mill entirely contactlessly via wear-free RFID (Radio-Frequency Identification) technology. This physical design is fundamental, as it completely eliminates the need for mechanical connectors, which could corrode during the rinsing process. You can set a strict, material-specific temperature limit via the drive’s control display. According to IKA, a temperature limit can be set to protect against overheating. Large-volume containment: the ‘S’ stands for ‘Sealed’ In addition to sensor-based temperature monitoring, the vessel resolves the biggest health and safety issue associated with high-speed dry milling: uncontrolled aerosol formation. The abbreviation “S” (Sealed) refers to the chamber’s innovative sealing and pressure-equalisation system. When extremely fine dusts are generated or samples are ground with the direct addition of dry ice (cryogenic grinding), gas expansion creates massive overpressure inside the vessel. The MI 400 T S features an intelligent pressure-equalising valve in the lid, combined with a microporous foam barrier. This mechanical barrier retains 100 % of the microfine, often toxic sample material within the vessel (containment), whilst allowing excess CO₂ or air pressure to escape safely. This protects laboratory staff from respirable dust and prevents quantitative loss of the analyte. Powerful grinding performance and dual cooling circuits The MI 400 T S works on the impact principle (impact grinding). The solid beater, supplied as standard and made from 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 material hardness of 5 on the Mohs scale. To keep the temperature as low as physically possible before the electronic sensor even needs to intervene, the chamber offers two professional thermodynamic cooling methods. It can be actively cooled via an external cooling jacket through which water flows, or the material being ground can be deep-frozen directly inside the chamber by adding dry ice. According to the manufacturer, the media-contacting surfaces made of stainless steel (1.4301) and chemically resistant silicone are FDA-compliant. For thorough decontamination, the beater can be completely dismantled without tools.

Individual requirements & accessories The thermal protection functions of the MI 400 T S can only be used in conjunction with the premium IKA MultiDrive control drive unit, as only this model is equipped with the necessary RFID receiver. If you need to process extremely fibrous material (such as cellulose or tough plastics) instead of hard, brittle samples, the vessel can be ideally upgraded with the separately available MultiDrive MI 400.2 star knife. Please feel free to contact our technical procurement service at any time for a professional and process-engineered design of your milling system.

Thermodynamic heat dissipation in high-speed grinding processes In the demanding sample preparation of hard, brittle or fibrous materials, controlling the process-induced frictional heat is the most important physical parameter. The conversion of kinetic rotational energy into mechanical comminution work inevitably generates massive amounts of thermal energy inside grinding chambers. For thermolabile analytes such as active pharmaceutical ingredients (APIs), volatile organic compounds (VOCs) or temperature-sensitive proteins, this uncontrolled rise in temperature leads to irreversible denaturation and thus to distorted analytical results. To physically eliminate this source of methodological error, IKA has developed the highly specialised MultiDrive CS 1 cooling system. This system enables active, liquid-based temperature control of the double-walled IKA MI grinding chambers and transforms your mill into a thermally stable grinding instrument for highly sensitive sample matrices. Highly efficient cooling circuits for continuous heat exchange The core technological principle of the CS 1 system is based on continuous convective heat exchange. The accessory set is fitted directly to the external cooling jacket of the compatible MI 250 or MI 400 grinding chambers. Through the continuous circulation of cold tap water or temperature-controlled coolant from a recirculating chiller, the impact and frictional heat generated is absorbed directly via the chamber’s heat-conducting stainless steel walls and dissipated from the system. This physical intervention effectively prevents heat build-up (thermal stress) within the grinding chamber. The key analytical advantage is that the material being ground does not sinter or stick to the chamber walls, and the moisture content of the sample remains absolutely constant throughout the entire batch process, which is of essential importance for subsequent gravimetric or chromatographic analyses. System integration and prevention of cross-contamination The precisely fitted connections and high-quality tubing of the CS 1 are designed for the rigours of everyday laboratory use and operation under hydrostatic pressure. In contrast to internal cryogenic grinding with dry ice (solid CO₂), where the cooling medium comes into direct physical contact with the sample, the CS 1 system operates as a purely external, closed cooling network. This prevents contact between the cooling medium and the sample, and thus chemical interactions with the analyte as well as microbiological or particulate contamination of the sample by the coolant. Increased process reliability and extended service life Active cooling protects not only the valuable sample but also the core mechanical components of the milling setup. The drastic reduction in thermal stress protects the sensitive shaft seals of the milling chambers and minimises thermomechanical wear on the stainless steel impact tools. This leads to a significant extension of the service life of your expensive accessories and measurably reduces the Total Cost of Ownership (TCO) of the entire IKA MultiDrive system. For laboratories with high sample throughput or for extremely long grinding intervals, during which the chamber would continuously heat up, the MultiDrive CS 1 cooling system is an essential process-related investment. Technical details Product type: Active cooling system / hose set for grinding chambers Operating principle: Convective heat exchange via a double-walled cooling jacket Cooling medium: Tap water or temperature-controlled liquid from an external recirculating cooler (chiller) Process engineering advantage: Prevents thermal denaturation and the release of VOCs Analytical advantage: Purely external cooling (no direct sample contact, no cross-contamination) Compatibility (grinding chambers): IKA MultiDrive MI 250 and MI 400 series (including T / S variants) Compatibility (drive): Compatible with IKA MultiDrive basic and MultiDrive control Materials: Pressure-resistant, highly flexible laboratory tubing with precisely fitting connection adaptors Maintenance: Maintenance-free flow-through system Scope of delivery 1 x IKA MultiDrive CS 1 cooling system (complete connection and hose set) (Important note: The essential MI grinding chambers and the IKA MultiDrive drive unit are not included in the scope of delivery!) Individual requirements & accessories To maximise the thermodynamic efficiency of this system and minimise your laboratory’s water consumption for both environmental and economic reasons, we recommend connecting it to a closed, active recirculating chiller (such as the IKA RC 2 basic). This ensures a constant inlet temperature, regardless of fluctuations in the in-house water supply. Please feel free to contact our procurement service, which specialises in process engineering, at any time for a bespoke design of your thermally monitored milling setup.

Thermodynamic process control in high-shear dispersion In the demanding fields of pharmaceutical formulation, cosmetic product development and chemical synthesis, the production of ultra-fine, long-term stable emulsions and suspensions is a thermodynamic stress test. The enormous amount of kinetic energy required to break up droplets or agglomerates inevitably leads to a massive rise in temperature within the medium due to molecular friction. For heat-labile ingredients such as active pharmaceutical ingredients (APIs), sensitive proteins or volatile organic compounds (VOCs), this results in irreversible denaturation or thermal degradation. To completely eliminate this source of methodological error in large-volume batches, IKA has designed the highly specialised MultiDrive DI 2000 T dispersion vessel. The “T” in the product nomenclature stands for the integrated temperature sensor. This 2,000-millilitre vessel transforms your IKA MultiDrive mill into a process-controlled, high-precision in-line homogeniser for thermally highly sensitive mixtures. Fluid dynamics of the rotor-stator principle In stark contrast to conventional mixing beakers (blender tubes), which operate with rotating impact blades that merely circulate and chop up the sample, the DI 2000 T is based on the highly complex rotor-stator principle. Inside the vessel, a solid stainless-steel rotor rotates at an extremely high peripheral speed within a stationary stator. The liquid medium is drawn axially into the dispersing head and forced radially through the microscopically fine slits in the stator. Within this extremely narrow shear gap, immense hydrodynamic shear forces, massive impact energy and cavitation act upon the sample. Liquid droplets (in emulsions) or solid particles (in suspensions) are broken down into tiny primary particle sizes within milliseconds, resulting in a homogeneous, reproducible phase distribution in up to 2 litres of working volume. Wireless RFID technology for seamless temperature monitoring The technological heart of the DI 2000 T is the seamless communication between the dispersion vessel and the drive unit. A high-precision temperature sensor is integrated into the solid base of the vessel, continuously measuring the thermal load on the sample directly within the flow zone. Data transmission to the essential IKA MultiDrive control is carried out entirely contactlessly via wear-free RFID (Radio-Frequency Identification) technology. Mechanical plug connections, which could corrode during intensive wet cleaning, are completely eliminated. You can set a strict, material-specific temperature limit via the drive unit. According to IKA, a temperature limit can be set to protect against overheating. Hygiene and material integrity When processing suspensions containing proteins or high levels of fat, the risk of cross-contamination (carry-over) is extremely high. The DI 2000 T is designed for thorough deep cleaning. The highly complex rotor-stator assembly, made from corrosion-resistant stainless steel, can be completely dismantled in just a few simple steps without the need for tools, allowing hidden biofilms or product residues in the shear gap to be removed completely. The large-volume housing is made of extremely impact-resistant and chemical-resistant PCTG plastic. This not only allows for constant visual monitoring of flow turbulence but, together with all components in contact with the medium, is fully dishwasher-safe. Technical details Product type: Dispersion vessel with rotor-stator system Maximum usable volume: 2,000 ml Process type: Batch operation Operating principle: High-shear dispersion (rotor-stator) Special feature (T = Temperature): Integrated temperature sensor in the vessel base Data transmission: Wireless via RFID technology (wear-free) Compatible drive: IKA MultiDrive control only (required for use of the RFID sensor system) Main area of application: Production of emulsions, suspensions and ultra-fine homogenates Processing advantage: Prevents thermal denaturation through proactive speed control at the limit Material (vessel): Impact-resistant, transparent PCTG plastic Material (dispersing tool): Wear-resistant, high-quality stainless steel Cleaning/hygiene: Dishwasher-safe; rotor-stator assembly can be completely dismantled for intensive cleaning Dimensions (W x H x D): 180 x 280 x 220 mm Weight: 1.35 kg Scope of delivery 1 x IKA MultiDrive DI 2000 T dispersion vessel (2,000 ml, incl. integrated RFID sensor) 1 x stainless steel rotor-stator dispersing tool (already fitted, can be dismantled without tools) (Important note: The essential IKA MultiDrive control drive unit is not included in the scope of delivery!) Individual requirements & accessories The DI 2000 T’s high-precision thermal protection functions can only be used in conjunction with the premium IKA MultiDrive control drive unit, as the ‘basic’ version cannot process RFID signals. If you need to cut up coarse tissue or grind dry solids rather than emulsions, we advise against using the rotor-stator principle and instead recommend the IKA MultiDrive MI (grinding chambers) or BL (blender) series. Our procurement service, which specialises in process engineering, will be happy to configure the physically optimal system for your specific sample matrices.

Kinetics of wet comminution and cell suspension In biological sample preparation, the extraction of sensitive phytochemicals and food analysis, the physical disruption of soft, water-containing or extremely fibrous tissue structures is the fundamental first step in the process. The IKA MultiDrive BL 2000.1 Standard Mixing Blade is the core fluid-mechanical tool for precisely these wet grinding and mixing processes. Driven by the MultiDrive base station at speeds of up to 30,000 revolutions per minute, the sharp, geometrically optimised blade shears through cellular matrices using massive mechanical shear forces. This continuous cutting process transforms coarse, heterogeneous samples into homogeneous, flowable suspensions, which are essential for subsequent chromatographic or spectroscopic analysis. Macroscopic fluid dynamics in the blender vessel Breaking down tough plant fibres or muscle tissue requires more than just a high rotational speed; it requires controlled rheology within the sample vessel. The fluid-dynamic architecture of the crossed blades of the BL 2000.1 blade is designed to maintain strong axial and radial circulation (vortex) within the large-volume BL 2000 blender vessel. The medium is continuously drawn from the periphery into the area of extreme turbulence (shear zone) created by the rotating blades. This flow profile prevents light sample fractions from floating to the surface, breaks down phase separations and ensures homogeneous particle distribution throughout the entire 2,000-ml batch volume without any process-related dead zones. Material integrity and hygiene When extracting active pharmaceutical ingredients (APIs) or conducting toxicological tests, avoiding cross-contamination (carry-over prevention) is essential. The entire mixing blade is made from solid, highly corrosion-resistant stainless steel. It easily withstands the oxidative effects of aqueous solutions, acidic plant extracts and aggressive cleaning agents. The robust, single-material design avoids complex, hard-to-reach undercuts and enables thermal sterilisation in an autoclave. Technical details Product type: Standard mixing blade (replacement / interchangeable tool) Process function: Cutting, wet grinding and homogenisation Fluid dynamics: Generation of strong axial and radial turbulence Blade architecture: Crossed, sharpened rotor blades Compatibility (vessel): Exclusively suitable for the IKA MultiDrive BL 2000 (blender vessel) Compatibility (drive): IKA MultiDrive basic and MultiDrive control Material: Solid, corrosion-resistant stainless steel Cleaning and hygiene: Fully autoclavable and chemically sterilisable Assembly: Quick, positive-lock tool change within the vessel Scope of delivery 1 x IKA MultiDrive BL 2000.1 standard mixing blade (stainless steel) (Important note: The MultiDrive drive unit and the BL 2000 vessel are not included in the scope of delivery!) Individual requirements & accessories The BL 2000.1 blade is the standard wear part for wet comminution. During the continuous processing of extremely hard, abrasive sample matrices (such as bone tissue or frozen agricultural products), the sharpness of the stainless steel blade is subject to natural mechanical wear. For laboratories with high sample throughput, it is metrologically advisable to always keep replacement blades in stock to safeguard the long-term reproducibility of the particle size distribution. Please contact our procurement service at any time to source consumables tailored to your requirements.

Kinetics of high-speed impact comminution In demanding inorganic analysis, geochemistry and pharmaceutical quality control, the physical comminution of hard and brittle sample matrices (such as minerals, ceramics, tablets or cereals) is the fundamental first step in the process. The IKA MultiDrive MI 250.1 standard grinding tool operates according to the process principle of impact and shock comminution. Driven by the MultiDrive base station at up to 30,000 revolutions per minute, the rotating stainless steel beater generates immense peripheral speeds at its outer edges. The massive kinetic energy generated in this process is transferred directly to the sample material in fractions of a millisecond. This extreme mechanical impulse overcomes the material’s internal tensile and compressive strength, leading to the immediate, abrupt shattering of the crystal lattices and macroscopic structures. Particle kinematics in the enclosed grinding chamber The fragmentation of dry samples requires controlled kinematics within the grinding chamber. The specific geometry of the MI 250.1 beater is physically precisely matched to the radius of the 250-ml grinding chamber. Due to the high-speed rotation, the particles are not only struck by the beater itself, but are also hurled with enormous acceleration against the stainless steel wall of the chamber, where they are further comminuted by additional impact energy. This continuous kinetic cycle of impact and rebound results in a highly homogeneous, reproducible particle size distribution in the analytically relevant micrometre range, without the formation of fluid dynamic dead zones. Material integrity and abrasion resistance When processing materials with a high Mohs hardness, the grinding tool is subjected to massive tribological stresses (wear caused by friction and impact). To physically minimise sample contamination by metallic abrasion (carry-over), the MI 250.1 beater is manufactured from a highly wear-resistant, solid stainless steel. This single-material design provides high structural integrity, even during repeated grinding cycles. The smooth, seamless metal surface can be thoroughly decontaminated and thermally sterilised in an autoclave. Technical details Product type: Standard beater (replacement / interchangeable tool) Processing principle: Impact milling Physical scope of application: Dry grinding of hard and brittle matrices Compatibility (vessel): Suitable exclusively for the IKA MultiDrive MI 250 (including the T version) Compatibility (drive): IKA MultiDrive basic and MultiDrive control Material: Solid, highly wear-resistant stainless steel Installation: Tool-free, form-fit replacement in the grinding vessel Cleaning and hygiene: Fully autoclavable and chemically sterilisable Scope of delivery 1 x IKA MultiDrive MI 250.1 standard beater (stainless steel) (Important note: The MultiDrive drive unit and the MI 250 grinding chamber are not included in the scope of delivery!) Individual requirements & accessories The MI 250.1 beater is the primary wear part in impact grinding. Despite the extreme hardness of the stainless steel, the continuous grinding of highly abrasive samples (such as quartz sand or ores) inevitably leads to gradual blunting and deformation of the striking edges. To maintain the thermodynamic efficiency and kinetics of the grinding process at the standardised laboratory level in the long term, regular replacement of the tool is essential. Please contact our procurement service at any time for the strategic procurement of consumables.

Kinetics of cutting and shear comminution In materials science and biological sample preparation, tough, elastic and extremely fibrous matrices (such as plastics, textiles, paper, root tissue or cellulose) present a major physical challenge. Conventional impact devices fail in this context, as elastic materials absorb the kinetic impact energy rather than breaking apart. The IKA MultiDrive MI 250.2 star blade is geometrically engineered for high-precision cutting and shear-based comminution. Driven by the MultiDrive base station at speeds of up to 30,000 revolutions per minute, the sharpened blades sever the macromolecular fibre structures by applying massive, localised shear stresses. This pulling cut continuously disaggregates the sample material and transforms it into a homogeneous, free-flowing matrix. Fluid mechanics and prevention of rotational blockages A fundamental mechanical problem in the high-speed grinding of long fibres is the so-called wrapping effect. Fibrous materials tend to wrap themselves around the rotating tool shaft due to flow turbulence within the reactor. This leads to an exponential increase in torsional resistance, which can thermally overload or jam the drive motor in a fraction of a second. The MI 250.2 star blade counteracts this rheological phenomenon thanks to its multi-bladed star geometry. The specific angles of attack of the blades direct the sample material radially outwards towards the chamber wall and systematically cut the fibres into short fragments, long before static wrapping structures can form around the shaft. Material integrity and mechanical resilience To withstand the continuous mechanical abrasion caused by tough polymers or woody biomass, the star blade is made from solid, highly wear-resistant stainless steel. The blades retain their microscopic sharpness even during extended grinding intervals under high thermal stress. The corrosion-resistant, single-material design can be thoroughly decontaminated chemically and thermally sterilised in an autoclave, which reduces the risk of cross-contamination between batches. Technical details Product type: Star blade (cutting tool / spare part) Processing principle: Cutting and shear comminution Physical scope of application: Tough, elastic and fibrous sample matrices Compatibility (vessel): Suitable exclusively for the IKA MultiDrive MI 250 (including the T version) Compatibility (drive): IKA MultiDrive basic and MultiDrive control Material: Solid, highly wear-resistant stainless steel Blade geometry: Multi-bladed star profile to prevent tangling Fitting: Tool-free, form-fit replacement in the grinding vessel Cleaning and hygiene: Fully autoclavable and chemically sterilisable Scope of delivery 1 x IKA MultiDrive MI 250.2 star blade (stainless steel) (Important note: The MultiDrive drive unit and the MI 250 grinding chamber are not included in the scope of delivery!) Individual requirements & accessories The MI 250.2 star blade is the most important wear part in terms of process engineering for cutting and comminution. Processing extremely tough or abrasive plastics (such as glass-fibre-reinforced polymers) inevitably leads to a gradual blunting of the cutting edges due to micro-collisions, which increases the thermodynamic stress on the sample (frictional heat) in the long term. To ensure gentle, thermally stable sample preparation, we recommend having replacement tools ready at an early stage should cutting performance begin to decline. Please contact our procurement service at any time for the strategic procurement of laboratory consumables.

Solid-state physics and tribological resistance In geochemical analysis, metallurgy and materials testing, the comminution of extremely hard, mineral or ceramic sample matrices reaches fundamental physical limits. Standard stainless steel grinding tools suffer severe tribological deformation and extreme material wear when used on matrices with a Mohs hardness of over 6. The IKA MultiDrive MI 250.3 beater is made entirely of tungsten carbide (WC). This hard material is characterised by extreme structural density and a hardness reaching values of up to 9.5 on the Mohs scale (just below diamond). This material superiority makes the tool resistant to plastic deformation caused by abrasive micro-collisions with hard ores, quartzites, glasses or slags. Kinetics of extreme impact crushing The physical principle of comminution remains identical to that of the standard beater: driven at up to 30,000 revolutions per minute by the MultiDrive system, the MI 250.3 transforms rotational energy into massive kinetic impact energy. Due to the extreme hardness and very high specific gravity of tungsten carbide, the mechanical impulse transferred to the sample material upon impact is significantly more rigid and results in less energy loss than with more elastic steel alloys. The lattice structures of even extremely brittle, crystalline solids are shattered by the incoming shock waves in fractions of a millisecond and converted into a highly fine, analytically usable powder matrix. Analytical purity and iron-free grinding A key problem in trace element analysis (for example, using ICP-OES or XRF) is sample contamination caused by abrasion of the grinding tool (carry-over). Grinding hard rocks with stainless steel tools inevitably leads to a massive introduction of iron, chromium and nickel ions, which distorts or renders impossible the quantitative elemental analysis of these metals in the sample. The use of the MI 250.3 tungsten carbide beater avoids this specific heavy-metal contamination. The sample material is only minimally doped with tungsten and carbon, which is metrologically irrelevant for most iron-focused geological or metallurgical analyses. Technical details Product type: Beater for extreme impact crushing (interchangeable tool) Material: Tungsten carbide (hard metal) Processing principle: Impact and percussion comminution (impact milling) Physical scope of application: Extremely hard and brittle matrices (ores, glass, ceramics) Hardness of the material: approx. 9 to 9.5 on the Mohs scale Analytical advantage: Prevention of iron, chromium and nickel contamination Compatibility (vessel): Exclusively suitable for the IKA MultiDrive MI 250 grinding chamber Compatibility (drive): IKA MultiDrive basic and MultiDrive control Fitting: Tool-free, form-fit replacement in the grinding vessel Scope of delivery 1 x IKA MultiDrive MI 250.3 beater (tungsten carbide) (Important note: The MultiDrive drive unit and the MI 250 grinding chamber are not included in the scope of delivery!) Individual requirements & accessories The MI 250.3 beater is designed for very hard materials. To consistently maintain the analytical integrity of the system during iron-free grinding, it is essential that not only the beater but also the grinding chamber itself does not cause any iron contamination. Although tungsten carbide is extremely hard, its crystalline structure makes it more susceptible to bending or lever forces than ductile stainless steel. The tool must never be forced into the vessel at an angle. Please contact our procurement service at any time for the metrologically correct configuration of your milling systems.

Kinetics of high-speed impact comminution at a larger scale In geochemical analysis, agricultural science and the quality control of building materials, the physical comminution of hard and brittle sample matrices (such as minerals, cereal pellets or ceramic precursors) requires a significant amount of mechanical energy. The IKA MultiDrive MI 400.1 standard grinding tool operates on the process engineering principle of impact and percussion grinding and is specifically dimensioned for the enlarged 400-ml grinding chamber. Driven by the MultiDrive base station (at up to 30,000 revolutions per minute), the rotating stainless-steel beater generates immense peripheral speeds at its extended outer edges. The resulting kinetic energy is transferred to the sample material in fractions of a millisecond upon direct impact. This extreme mechanical impulse overcomes the internal tensile and compressive strength of the solids, leading to the sudden shattering of the crystal lattices. Particle kinematics and volume scaling Processing larger sample volumes (up to 400 ml) significantly alters the macro-kinematics within the enclosed grinding chamber. The specific length geometry of the MI 400.1 beater is precisely calculated, in accordance with the laws of physics, to match the extended radius of the MI 400 chamber. The high-speed rotation hurls the particles against the stainless steel wall with enormous radial acceleration. The increased distance between the axis of rotation and the chamber wall creates a highly efficient kinetic cycle comprising a primary impact and a secondary impact against the wall. This optimised geometry ensures that, despite the increased batch volume, no fluid dynamic dead zones arise and a reproducible particle size distribution is achieved in the analytically relevant micrometre range. Material integrity and tribological resistance When comminuting samples with a high Mohs hardness, the tool is subjected to severe tribological stresses (mechanical wear caused by friction and micro-collisions). To minimise analytical contamination of the sample due to metallic abrasion (carry-over), the MI 400.1 beater is manufactured from a highly wear-resistant, solid stainless steel. The structural integrity of this monomaterial design prevents plastic deformation of the striking edges. The electropolished metal surface can be thoroughly decontaminated chemically and thermally sterilised in an autoclave. Technical details Product type: Standard beater for increased chamber volume (interchangeable tool) Process principle: Impact and percussion comminution (impact milling) Physical scope of application: Dry milling of hard and brittle matrices Compatibility (vessel): Exclusively suitable for the IKA MultiDrive MI 400 (400 ml chamber) Compatibility (drive): IKA MultiDrive basic and MultiDrive control Material: Solid, highly wear-resistant stainless steel Assembly: Tool-free, form-fit attachment to the drive shaft inside the vessel Cleaning and hygiene: Fully autoclavable and solvent-resistant Scope of delivery 1 x IKA MultiDrive MI 400.1 standard beater (stainless steel) (Important note: The MultiDrive drive unit and the large-volume MI 400 grinding chamber are not included in the scope of delivery!) Individual requirements & accessories The MI 400.1 beater is the primary mechanical wear part in impact grinding. The continuous grinding of highly abrasive materials inevitably leads to a gradual blunting of the striking edges. This prolongs the required grinding time and increases the undesirable thermodynamic energy input (friction heat) into the sample. To keep the kinetics of the grinding process and the reproducibility of particle sizes in long-term compliance with standards, regular replacement of the tool is essential. Please contact our procurement service at any time for the strategic procurement of laboratory consumables.

Kinetics of cutting and shear comminution at larger scale In large-volume materials science and biological sample preparation, tough, elastic and extremely fibrous matrices (such as plastics, textiles, paper or dense root tissue) present a major physical challenge. Elastic materials absorb kinetic impact energy rather than breaking. The IKA MultiDrive MI 400.2 star blade is geometrically engineered for high-precision cutting and shear comminution in the scaled 400 ml grinding chamber. Driven by the MultiDrive base station at speeds of up to 30,000 revolutions per minute, the solid star blades sever the macromolecular fibre structures by applying massive, localised shear stresses. This pulling cut continuously disaggregates the sample material and transforms it into a homogeneous, free-flowing matrix, even with large batch volumes. Macro-fluid dynamics and the prevention of rotational blockages A fundamental mechanical problem in the high-speed grinding of long fibres, which is further exacerbated by increased flow turbulence in large-volume chambers, is the so-called wrapping effect. Fibrous materials tend to wrap themselves around the rotating tool shaft. This leads to an exponential increase in torsional resistance, which can cause the drive motor to overheat. The MI 400.2 star blade overcomes this rheological phenomenon thanks to its multi-bladed star geometry, which is calculated to match the radius of the 400-ml chamber. The enlarged blades direct the sample material radially outwards towards the chamber wall and systematically cut the fibres long before static wrapping structures can form around the shaft. Material integrity and mechanical resilience To withstand the continuous mechanical abrasion caused by tough polymers or woody biomass in large batches, the star blade is manufactured from solid, highly wear-resistant stainless steel. The blades retain their microscopic sharpness even during extended grinding intervals under high thermal stress. The corrosion-resistant, single-material design can be thoroughly decontaminated chemically and thermally sterilised in an autoclave, which reduces the risk of carry-over between large batches. Technical details Product type: Star blade (cutting tool for large volumes / spare part) Processing principle: Cutting and shear comminution Physical scope of application: Tough, elastic and fibrous sample matrices Compatibility (vessel): Exclusively suitable for the IKA MultiDrive MI 400 (400 ml chamber) Compatibility (drive): IKA MultiDrive basic and MultiDrive control Material: Solid, highly wear-resistant stainless steel Blade geometry: Scaled, multi-bladed star profile to prevent tangling Fitting: Tool-free, form-fit attachment to the drive shaft inside the vessel Cleaning and hygiene: Fully autoclavable and solvent-resistant Scope of delivery 1 x IKA MultiDrive MI 400.2 star blade (stainless steel) (Important note: The MultiDrive drive unit and the MI 400 grinding chamber are not included in the scope of delivery!) Individual requirements & accessories The MI 400.2 star blade is the most important wear part in terms of process engineering for high-volume cutting and comminution. Processing extremely tough or abrasive samples inevitably leads to gradual blunting of the cutting edges due to mechanical stress. A blunt blade drastically increases the thermodynamic stress on the sample (frictional heat). To ensure gentle, thermally stable preparation of large batches, we recommend having replacement blades ready at an early stage should cutting performance begin to decline.

Solid-state physics and tribological resistance in scaled-up volumes In geochemical analysis, metallurgy and construction materials testing, the large-volume comminution of extremely hard, mineral or ceramic sample matrices reaches fundamental physical limits. Standard stainless steel grinding tools suffer severe tribological deformation and extreme material abrasion when processing large batches of matrices with a Mohs hardness of over 6. The IKA MultiDrive MI 400.3 beater is made entirely of tungsten carbide (WC). This hard material is characterised by extreme structural density and a hardness reaching values of up to 9.5 on the Mohs scale. This material superiority makes the tool resistant to plastic deformation caused by abrasive micro-collisions with hard ores, quartzites or slag, even within the extended 400 ml grinding chamber. Kinetics of extreme impact comminution on a macro scale Driven at up to 30,000 revolutions per minute by the MultiDrive system, the MI 400.3 transforms rotational energy into massive kinetic impact energy. Thanks to its specific length geometry, calculated for the 400-ml chamber, the tool generates immense peripheral speeds at its outer edges. Due to the extreme hardness and very high specific gravity of tungsten carbide, the mechanical impulse transferred upon impact with the high-volume sample material is significantly more rigid and results in less energy loss than is the case with more elastic steel alloys. The crystal structures of extremely brittle solids are shattered by these radial shock waves in fractions of a millisecond and converted into a very fine powder matrix without creating any fluid-dynamic dead zones. Analytical purity and iron-free grinding A key problem in trace element analysis (using ICP-OES or XRF) of large rock or soil samples is contamination caused by abrasion of the grinding tool (carry-over). Grinding hard ores with stainless steel tools inevitably leads to a massive introduction of iron, chromium and nickel ions, which distorts the quantitative elemental analysis of these metals. The use of the MI 400.3 tungsten carbide beater avoids this specific heavy-metal contamination. The sample material is only minimally doped with tungsten and carbon, which is metrologically irrelevant for most iron-focused geological or metallurgical trace analyses.

Individual requirements & accessories The MI 400.3 beater is designed for very hard materials in large batches. To maintain analytical integrity throughout the iron-free grinding process, it is essential that the grinding chamber used also does not cause any iron contamination. Tungsten carbide is extremely hard, but due to its crystalline structure, it is more susceptible to bending or lever forces than ductile stainless steel. The tool must never be forcibly jammed during tool changes. Please contact our procurement service at any time for the metrologically correct configuration of your high-performance grinding systems.

The IKA MultiDrive MT 150.5 is a plastic grinding beaker with a stainless steel beater for dry samples. It is used in the MultiDrive control universal mill; one pack contains 5 beakers. The plastic is transparent, allowing the changes in the material being ground to be observed during the grinding process. The usable volume is a maximum of 150 ml; the maximum feed particle size is 10 mm at 5 Mohs.RFID chip, seals and autoclavingAn RFID chip in the beaker stores the service life and limits it. The scope of delivery includes 5 replacement seals; fitting a new seal extends the service life. The beaker is autoclavable. According to IKA, sterilisation in an autoclave prevents cross-contamination. Materials in contact with the product are stainless steel, PA, PC, PTFE and silicone. According to the manufacturer, FDA conformity is given.TC 1 protective housingFor safety reasons, the MultiDrive will only start if the TC 1 protective housing is connected.
