Cole-Parmer® SamplePrep Freezer/Mill® Cryogenic Grinders

Designed for grinding tough or temperature-sensitive samples

"The Freezer/Mill® programmable cryogenic grinder pulverizes through the toughest samples at cryogenic temperatures. Samples are placed in a vial and immersed in a self-contained insulated liquid nitrogen (LN2) tub, reaching cryogenic temperatures in minutes, where they are then pulverized with a magnetically driven impactor. The closed grinding vial impactor prevents sample cross-contamination. The single grinding and cooling chamber allows you to pre-cool and grind two sets of samples simultaneously.

Grind temperature sensitive samples while maintaining constant temperature, as the sample never leaves the enclosed liquid nitrogen bath. Enhanced safety features include a liquid nitrogen sensor and lid interlock. If the lid is opened while in process, grinding will stop. Auto-fill system is available for automated liquid nitrogen filling.

The large, high-resolution touch screen controls all parameters of the run. Store up to 20 user-defined grinding programs for quick and easy recall. The user-friendly interface allows you to view training videos, user manual, and run history, which can be transferred to a computer using a thumb drive.
