- Model 6775 - Cryogenic Grinder



The 6775 Freezer/Mill® is a small cryogenic mill that is perfrect for grinding small samples in the range of 0.1 – 5 grams. It is specifically designed to cryogenically grind tough and/or temperature sensitive samples. The mill cools samples to cryogenic temperatures, then pulverizes them by magnetically shuttling a steel impactor back and forth against two stationary end-plugs. Since the vial is closed, the integrity of its contents is maintained, hazardous or critical samples are easily controlled, cleanup is simplified and cross-sample contamination is eliminated.
