Our programmable cryogenic mills are specifically designed for grinding tough or temperature-sensitive samples. Sample vials are continuously cooled with liquid nitrogen while samples are pulverized by magnetically shuttling a steel impactor back-and-forth against the vial end plugs. Since the vials are closed, the integrity of the contents is maintained, hazardous or critical samples are easily controlled, cleanup is simplified, and cross-contamination is minimized. An intuitive touchscreen control panel allows users to save up to 20 grinding protocols.
