The Autofill system avoids direct contact with LN2 and makes cryogenic grinding very safe. Its versatility (cryogenic, wet and dry grinding at room temperature) makes the CryoMill the ideal grinder for quantities up to 20 ml. You may also be interested in the High Energy Ball Mill Emax, an entirely new type of mill for high energy input.
The CryoMill is a cryogenic grinder designed with user safety in mind. The liquid nitrogen flows through the closed system and the user never comes into direct contact with LN 2 which ensures a high degree of operational safety. The automatic cooling system guarantees that the grinding process is not started before the sample is thoroughly cooled.
