Efficient Grinding at –196 °C

The CryoMill has been specially designed for cryogenic grinding. The mill features an integrated cooling system which continually cools the grinding jar with liquid nitrogen before and during the grinding process. Thus the sample is embrittled and volatile components are preserved. The CryoMill does not require bothersome manual refilling with LN2. The liquid nitrogen circulates through the system and is continually replenished from an autofill system in the exact amount which is required to keep the temperature at ?196?C. The automatic cooling system guarantees that the grinding process is not started before the sample is thoroughly cooled. This results in reduced consumption and guarantees reproducible grinding results. The operation of the mill is exceptionally easy. The grinding parameters can be stored and called up for routine tasks. The display features LED lights which indicate the current state of operation, e.g. cooling or grinding. With a vibrational frequency of 25 Hz the CryoMill processes sample 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 no-loss screw-top grinding jars of 25 ml, 35 ml and 50 ml. Another option is the use of an adapter which holds up to four 5 ml grinding jars. The mill can also be operated without cooling which makes it suitable for a vast range of applications.
