Freezer Mill 6970 EFM – Large High-Throughput Cryogenic Mill

The latest advance in cryogenic grinding.  Our 6970EFM Freezer/Mill® is a large high-throughput cryogenic mill that accommodates samples from 0.1 – 100 grams (0.1 – 50 mL). It is specifically designed to grind through the toughest samples and temperature sensitive samples through the use of magnetically-driven impactors. The 6970EFM is available in single and dual grinding chamber models for increased sample throughput. Chambers can be programmed for independent operation and different protocols, providing flexibility and speed.
