6875 Freezer/Mill® High Capacity Cryogenic Grinder

The 6875® Freezer/Mill is a large cryogenic grinder that accomodates samples from 0.1 to 100 grams. It has one dual purpose chamber that precools and grinds samples and can hold one large grinding vial, one mid-sized vial, four small grinding vials, or four microvial sets.  Sample vial maintains cryogenic temperatures due to continuous immersion in liquid nitrogen.  Heat sensitive metabolites, isomers and complex molecules retain their composition as they are not degraded by heat or pressure.  Grinding vial sets are offered in a variety of materials including polycarbonate, stainless steel, and low-chrome steel.  Optional auto-fill system is available to automatically fill the bath with liquid nitrogen.

  • Typical Applications: DNA/RNA extraction, forensic/drug testing, RoHS/WEEE, consumer product testing, food safety, materials research & medical research
  • 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.

Freezer/Mill® for RoHS WEEE Applications

Many components such as circuit boards, wire, solder, polymers and resins are difficult if not impossible to grind using traditional methods. Cryogenic grinding in the Freezer/Mill® is the easiest way to homogenize these materials for RoHS WEEE applications. Using cryogenic grinding to chill samples until they are brittle, and then break them up through impact, crushing, or shearing allows the toughest samples to be ground.
