Some samples are impossible to grind at ambient temperatures. 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.
Since the vials are sealed, the cryogenic grinder maintains the integrity of its contents. Volatile compounds are retained, hazardous or critical samples are easily controlled, cleanup is simplified and cross-sample contamination is eliminated.
Typical samples include: Animal tissue, plastic and polymers, yeast cultures, pharmaceuticals, tough or sticky food products, electronic components, textiles, hair, teeth, bones, plant tissue, cannabis and packaging.
