CoolCell® Controlled Rate, Alcohol-free, Freezing Containers

CoolCell controlled-rate alcohol-free cell freezing containers provide a highly reproducible -1℃/minute freezing rate when placed in a -80℃ freezer. No alcohol or fluids required. The insulative outer housing and thermo-conductive solid state core ensure consistent heat removal to all vials throughout the freezing period. CoolCell freezing containers are unbreakable, open easily when frozen, and are not cold to the touch when frozen - no "frosty" fingers. Numbered vial wells ensure easy sample identification. The beveled junction between base and lid and exposed vial tops in the base allow for quick and safe removal of frozen vials so they can be placed into long-term storage. Proven for use with stem cells, primary cells and cell lines.

CoolCell Freezing Profile Consistency

coolcell reproducibility graph

Performance Test: A temperature probe was placed into a 2.0 mL cryogenic vial containing 1.0 mL of water and the tube inserted into a CoolCell sitting at room temperature. The CoolCell container was then placed directly into a -80˚C freezer and the temperature rate and profile was observed over a 3 hour period. The experiment was repeated 5 consecutive times and the temperature profiles were recorded.

Conclusion: The CoolCell controlled-rate cell freezing container showed identical fusion time and cooling profiles over five consecutive freeze cycles.
