The CG-400 Freezer/Mill is a large cryogenic grinder that
accommodates samples from 0.1 to 100 grams. It has one dual-purpose
chamber that precools and grinds samples. 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.
The CG-400 is available with manual liquid nitrogen fill or with auto-fill (CG-450).
Typical applications include: DNA/RNA extraction, forensic/drug testing, RoHS/WEEE, consumer product
testing, food safety, materials research, and medical research.
Typical samples include: Animal tissue, plant tissue, plastics and polymers, yeast, pharmaceuticals, food
products, electronic components, textiles, hair, teeth, and bones.
