Ortho Clinical Diagnostics - CryoMill

Manufactured by Ortho Clinical Diagnostics

For cryogenic grinding

The CryoMill has been specially designed for cryogenic grinding. The grinding jar is continually cooled with liquid nitrogen from the integrated cooling system before and during the grinding process. The liquid nitrogen circulates through the system and is continually replenished from an autofill system in the exact amount which is required to keep the temperature at –196 °C. The automatic cooling system guarantees that the grinding process is not started before the sample is thoroughly cooled. This results in reduced consumption and guarantees reproducible grinding results.

Application Examples:
animal feed, bones, chemical products, hair, oil seeds, paper, plant materials, plastics, sewage sludge, soils, tablets, textiles, tissue, waste samples, wood, wool, ...

Also Available:
Mixer Mill MM 200 for dry grinding
Mixer Mill MM 400 for dry, wet and cryogenic grinding
