Cryogenic grinding Freezer/Mill®. SPEX Europe s Freezer/Mill® is a programmable cryogenic mill specifically designed for grinding and pulverizing tough or temperature sensitive samples. This technique makes a difference especially for soft, sticky, tough, lubricating and fibrous samples or for samples whose composition or structure changes due to the heat generated by conventional grinding.

Cryo Milling | Material Milling | AVEKA

Cryogenic milling, or cryo-milling, is the process of using liquid nitrogen to lower the temperate of the material and/or the milling process. AVEKA s cryogenic hammer mills can typically reduce the particle size from small pellets down to the 100s of microns. Cryo-milling can be used for:

Cryogenic grinding - Wikipedia

Cryogenic grinding of plant and animal tissue is a technique used by microbiologists. Samples that require extraction of nucleic acids must be kept at 80 °C or lower during the entire extraction process. For samples that are soft or flexible at room temperature, cryogenic grinding may be the only viable technique for processing samples.
