Mixer mill, CryoMill

The CryoMill has been specially designed for cryogenic grinding and it is ideal for plastics, temperature sensitive materials or samples with volatile components. Applications include cell disruption, cryogenic, wet and dry grinding of hard, medium hard, soft, brittle, elastic or fibrous materials. The grinding jar is continually cooled with liquid nitrogen at –196 °C from the integrated cooling system before and during the grinding process.

• Final fineness down to approx. 5 μm by impact and friction
• Fast, efficient cryogenic grinding at –196 °C, the integrated cooling system and with optional autofill means no manual cooling is needed
• Highly reproducible grinding results
• Programmable cooling and grinding cycles and digital parameter setting
• Can also be operated without cooling, making it suitable for a vast range of applications

The sample is embrittled and any volatile components are preserved. The grinding parameters can be stored, which helps to simplify routine tasks. LED display shows the current operation status, e.g. cooling and/or grinding. The size reduction principle is the same as that of the MM 400. With a vibrational frequency of up to 25 Hz, the CryoMill grinds most materials very effectively in a few minutes. The sample is mainly ground by impact but also by friction which allows for substantially finer grind sizes compared to other cryogenic mills. The CryoMill is equipped with one grinding station for grinding jar volumes of 25 ml, 35 ml and 50 ml. Another option is the use of an adapter which holds a 5 ml grinding jar**.

 : The autofill system and the grinding jars and grinding balls need to be ordered separately.

 : * Depending on feed material and instrument configuration/settings
** Adapter required for use of 2 or 4 grinding jars, 5 ml nominal volume
