The Freezer/Mill® is a programmable cryogenic grinder specifically designed for milling and grinding of tough or temperature sensitive samples. Samples are placed in sealed cryogenic grinding vials then immersed in liquid nitrogen (LN). The samples are cooled to cryogenic temperatures then ground by a magnetically shuttling impactor.
