Product information "IKA MTC 40.100 Lids for disposable grinding cups, 100 pieces, 0020001182"
Fluid mechanics and hermetic aerosol containment
The high-speed impact grinding of dry, brittle solids in the IKA Tube Mill System generates immense thermodynamic and fluid-mechanical stresses. Rotational speeds of up to 25,000 revolutions per minute generate strong hydrodynamic turbulence and significant internal overpressure within the MT 40 grinding chamber. The ground material is partially converted into microscopically fine, respirable dust (aerosols). The IKA MTC 40 lid acts as a critical physical barrier against this internal pressure. It seals the system by form fit and force fit and functions as a hermetic containment system that prevents the escape of potentially toxic, biohazardous or highly potent active pharmaceutical ingredients (APIs) into the laboratory atmosphere.
Polymer physics and thermomechanical dimensional stability
The conversion of kinetic energy into frictional heat (exothermic reaction) subjects the grinding chamber to thermal stress during the grinding process. The MTC 40 lids are made from a high-performance thermoplastic polymer whose macromolecular structure is precisely engineered to withstand these thermomechanical stress peaks. The geometry of the sealing lips retains its physical dimensional stability even as temperatures rise within the reaction chamber. Softening or plastic deformation of the lid, which would lead to micro-leakage and the loss of the system’s hermetic seal, is avoided by the polymer’s high glass transition temperature.
Elimination of carry-over and analytical sample archiving
In high-throughput laboratories (high-throughput analytics), the prevention of molecular cross-contamination (carry-over of DNA fragments or chemical traces) is the paramount analytical principle. The MTC 40.100 Set (bulk pack of 100 units) supports the Tube Mill’s strict single-use concept. Once the grinding process is complete, the sample vessel can be permanently sealed with the lid and transferred directly to cold storage or long-term archiving. The thermodynamically complex process of transferring the fine-powdered matrix, which always poses a risk of contamination and exposure to the user, is completely eliminated.

Individual requirements & accessories
The MTC 40 lids are purely sealing and safety components that fulfil their technical function exclusively in conjunction with the IKA MT 40 disposable grinding cups. For forensic, clinical or geochemical laboratories processing hundreds of samples per week, the combination of MT 40 cups and MTC 40 lids is a process engineering solution to reduce the risk of cross-contamination along the process chain, from grinding through to long-term archiving. Please contact our procurement service at any time for strategic demand planning of consumables.
Fits
To grind small, dry samples whilst preventing any cross-contamination between batches: that is what the IKA Tube Mill control is designed for. The batch mill operates with a patented disposable grinding cup with a volume of up to 40 ml, achieves a speed of up to 25,000 revolutions per minute and is specifically designed for hard, brittle materials such as seeds. After grinding, the cup is not cleaned but replaced with a new one, which saves time between samples and eliminates the risk of carry-over. For laboratories that process many small batches in succession, for example, in seed testing, this is precisely what makes the difference to their daily workflow.Disposable grinding cup with safety featuresThe supplied MT 40 has a maximum capacity of 40 ml of sample material and is designed to process hard, brittle and dry materials up to Mohs hardness 5 with a maximum feed particle size of 10 mm. The grinding cup and cover are made of transparent plastic, allowing for visual inspection during the grinding process. The safety feature detects if the grinding cup is missing or not correctly sealed and prevents the machine from starting; an error message appears on the display. The cup remains closed during operation; a labyrinth seal between the drive and the cup retains dust, whilst the closed housing also reduces noise levels in everyday laboratory use.Display, timer and interfaceA multilingual OLED display shows speed, timer and error codes; operation is via a sealed membrane keypad. The timer ranges from 5 seconds to 3 minutes; interval operation can be activated if short pauses between grinding phases are required, for example to allow the chamber to cool down in the meantime. Test conditions can be programmed and saved, making repeated grinding runs reproducible without having to reset the speed and time each time. A USB-B interface connects the mill to a computer for experiment control and documentation; the appropriate cable is supplied. Heat-sensitive material can also be cooled using dry ice without the need to open the cup.Typical applicationsThe 40-ml cup is particularly suitable for small to medium sample sizes, such as those encountered in routine seed testing.Grinding of seeds such as maize and wheat prior to analysisBatch sample preparation without the need for cleaning between batchesDigestion of hard, brittle and dry materials up to Mohs hardness 5Reproducible test series thanks to stored programsTechnical detailsMax. useful volume40 ml (MT 40)Motor power input / output100 W / 80 WSpeed range5,000 to 25,000 rpm, deviation ±2 %Maximum peripheral speed65 m/sFeed materialup to Mohs hardness 5, particle size max. 10 mmDuty cycle (ON)3 minInterfaceUSB-BPermissible ambient conditions5 to 40 °C, max. 80 % relative humidityConnected load220 to 240 V, 50/60 Hz, 100 W (100 to 120 V version available)Degree of protectionIP 30 (DIN EN 60529)Dimensions W x H x D180 x 170 x 300 mmWeight2.7 kgScope of delivery1 x Tube Mill control drive unit1 x MT 40 milling tube, 40 ml1 x MMT 40.1 reusable grinding cup1 x Coupling extractor1 x USB A-to-B cableAt the end of its useful life, this electrical appliance must be disposed of via the separate collection scheme for waste electrical and electronic equipment and must not be placed in household waste.Individual requirements and procurement serviceThose who regularly grind larger sample volumes of up to 100 ml are better served by the IKA Tube Mill 100 control, which also accommodates the larger MT-100 cup. For seed and grain analysis involving high cup consumption, the IKA Tube Mill control Agriculture Solution combines the same drive unit with a set of 10 disposable grinding cups. Additional grinding chambers and accessories for IKA mills can be requested via our procurement service, as can customised combinations of several cup formats. IKA provides a 2-year manufacturer’s warranty on the unit, which is extended to 3 years upon registration at ika.com/register within 90 days of purchase.Frequently Asked QuestionsWhat is the capacity of the grinding cup supplied?The MT 40 has a maximum capacity of 40 ml; a reusable cup (MMT 40.1) is also included.Will the unit start even if the cup is not correctly sealed?No, the safety electronics detect a missing or incorrectly sealed cup and will then prevent the unit from starting.How long is the warranty valid for?IKA provides a 2-year manufacturer’s warranty, which is extended to 3 years if you register at ika.com/register within 90 days of purchase.What is the difference between the Tube Mill control and the Tube Mill 100 control?The Tube Mill control is designed solely for the 40-ml cup, whilst the Tube Mill 100 control also accommodates the larger 100-ml cup and is therefore slightly taller and heavier.Can the ground material be cooled?Yes, the grinding chamber can be cooled with dry ice whilst the cup remains closed.What is the difference between the MT 40 and the MMT 40.1 supplied with the unit?The MT 40 is a disposable cup for cross-contamination-free individual samples, whilst the MMT 40.1 is a reusable cup of the same size for applications where this is not a requirement. Both are included in the scope of delivery.
