CoolCell alcohol-free cell-freezing containers from Biocision, Larkspur, Calif, ensure standardized cell freezing without alcohol or fluids at a controlled rate of -1° per minute in a -80° freezer. Intended for use with a variety of cell types, including stem cells, primary cells, and cell lines, the containers use a thermo-conductive alloy and insulative outer materials to maintain the rate of heat removal and make cell cryopreservation reproducible. The units accommodate up to 12 cryogenic vials and are available in two sizes for 1 to 2 mL vials or 3.5 to 5 mL vials. A beveled design simplifies sample transfer by providing ready access to the vial tops, while numbered vial holes enable indexing and rapid removal. For more information, visit Biocision.
