The 6875 Freezer/Mill is a large cryogenic mill that can grind up to 0.1 - 100 grams of samples. 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. The new high resolution display is user-friendly and includes the following features:

• Run history which is uploadable to a thumb drive via USB
• Training videos and manuals that can be viewed on the screen. 
• A complete listing of accessories

Applications include: DNA/RNA extraction, THC extraction, protein extraction, forensic testing, materials testing, pharmaceutical analysis, drug testing, RoHS/WEEE and volatiles extraction.

Typical samples include: Animal tissue, plastic and polymers, yeast, pharmaceuticals, food products, electronic components, textiles, hair, teeth, bones, plant tissue such as cannabis, seeds, leaves and roots.
