IKA MMT 40.1 Reusable grinding beaker, 40 ml, 0020003165

Kinematics of impact crushing and system reversibility

In the analytical sample preparation of brittle, hard or fibrous matrices, the application of substantial kinetic energy is essential. The IKA MMT 40.1 grinding beaker utilises the process principle of high-speed impact and shock comminution on a 40-ml scale. Unlike the MT series, this module is designed as a reversible, reusable system. A solid stainless-steel beater rotates at the geometric centre of the chamber. Driven by the magnetic coupling of the IKA Tube Mill base station at up to 25,000 revolutions per minute, the tool transmits enormous shock waves to the solids, shattering their macroscopic lattice structures and transforming them into a homogeneous powder matrix. The design as a reusable vessel requires precise metrological cleaning after each batch to physically rule out analytical cross-contamination (carry-over).

Thermomechanical stability and tribological wear

The repeated high-speed comminution of extremely hard samples induces significant, cyclic thermodynamic stress (exothermic reaction) due to friction and collisions with the vessel walls. The MMT 40.1 grinding chamber is manufactured from a structurally cross-linked, high-performance thermoplastic. This specific plastic matrix is engineered not only to withstand the massive kinetic impacts of rock fragments without undergoing plastic deformation, but also to resist chemical and thermal degradation during repeated mechanical cleaning (dishwasher-safe). However, the rotating drive shaft and the dynamic sealing elements are subject to natural tribological wear under continuous abrasive stress, which requires preventive maintenance.

Aerosol containment and system hermeticity

During the grinding of toxic, biohazardous or highly potent active pharmaceutical ingredients (APIs), the rotor generates significant fluid-dynamic turbulence and internal pressure spikes. When in operation, the MMT 40.1 grinding bowl functions as a hermetically sealed containment system. The built-in elastomer seals absolutely reliably prevent the escape of respirable fine dust or toxic aerosols into the laboratory atmosphere. To ensure this critical system hermeticity in the long term, the chamber’s seal integrity must be evaluated from a process engineering perspective following numerous rinsing and grinding cycles.

Individual requirements & accessories

The MMT 40.1 reusable grinding jar is the economically and environmentally scalable solution for laboratories with moderate sample throughput or homogeneous sample matrices, where the risk of serious cross-contamination can be managed through validated cleaning procedures. Please note that the dynamic elastomer seals in the rotational axis are subject to wear. To prevent a sudden loss of aerosol containment or irregular kinematics, these wear parts must be replaced at regular intervals. For this purpose, use only the original IKA A-MMT.100 spare parts kit (item no. 0020003378). Please contact our procurement service at any time regarding the strategic procurement of spare parts.
