Spex SamplePrep Large Dual Freezer/Mill, 115V/60Hz

The 6875D Freezer/Mill� is a high-throughput, dual chamber cryogenic grinder with a self-contained liquid nitrogen tub and insulated case.�It is specifically designed for cryogenic grinding of 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
