Cryomill - the perfect mill for cryogenic grinding - RETSCH
The cryogenic tissue pulverizer processes surgically-removed tissue by freezing and grinding the sample into a powder (10 µm diameter particles). To accomplish this task, our design incorporates a pneumatic driven grinding head with a grinding chamber. After careful consideration between motor and pneumatic driven designs, a pneumaticallyOct 01, 2009 · Cryogenic grinding involves cooling a material below its embrittlement temperature with a cryogenic fluid, typically liquid nitrogen or, in certain applications, carbon dioxide. After cooling, the material is fed into an impact mill where it is reduced in size primarily by brittle fracture.
