CG-200 Freezer/Mill® – Cryogenic Grinder


The CG-200 Freezer/Mill, is a compact cryogenic mill that accommodates samples from 0.1 – 5 grams. It has one dual purpose chamber that precools and grinds samples and can hold one small grinding vial, or one microvial set.  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.

Typical Applications: DNA/RNA extraction, protein & metabolite extraction, forensic/drug testing, RoHS/WEEE, consumer product testing, materials research & medical research

Typical Samples: Plant and animal tissue, plastic and polymers, yeast, pharmaceuticals, food products, electronic components, textiles, hair & bones.
