Description and ApplicationsFreezer Mill

The compact, benchtop Freezer/Mill from SPEX Sample Prep is designed for grinding and homogenizing 0.1-5 grams of temperature-sensitive, tough samples in minutes. The Freezer/Mill can perform these tasks on cartilage, bone/demineralized bone matrix, synthetic polymers (PLGA, nitrocellulose), natural polymers (collagen), and temperature-sensitive protein samples. It can also facilitate the preparation of desirable particle sizes for 3D bioinks as well as DNA/RNA/protein extractions.

Accessories include three sets of grinding vials: a polycarbonate set for metal-free grinding of delicate samples, a stainless steel set for samples incompatible with polycarbonate (both for sample sizes ranging from 1-2 g of polymer or 2-4 g of bone), and a microvial grinding set for samples between 30 mg and 200 mg. Frequent users are requested to acquire their own grinding vials.
