Cryogenic Cooling Pulverizer

Cryogenic Pulverizer is the act of cooling or chilling a material and then reducing it into a small particle size. When chilled by dry ice, liquid carbon dioxide or liquid nitrogen, the thermoplastics can be finely ground to powders suitable for electrostatic spraying and other powder processes. Samples that require extraction of nucleic acids must be kept at −196 °C or lower during the entire extraction process.
