The Freezer/Mill®, a cryogenic mill is useful where other grinding procedures fail. Flexible materials like synthetics and biological samples are embrittled at Liquid Nitrogen temperatures. The sample is hermetically sealed and cross contamination is impossible. Since the Freezer/Mill is driven magnetically there is no wear and tear on the movable parts.
