CoolCell 5ml LX alcohol-free freezing container holds 12, 3.5 mL to 5.0 mL cryogenic vials and provides a highly reproducible -1℃/minute freezing rate when used in a -80℃ freezer. No alcohol or fluids required. The insulative outer housing and thermo-conductive core ensure consistent heat removal to all vials throughout the freezing period. CoolCell containers are unbreakable, open easily when frozen, and are not cold to the touch when frozen - no "frosty" fingers. Enhanced design features include beveled junction between base and lid to allow quicker opening once frozen, numbered vial wells for easy sample identification, and exposed vial tops when container is open allowing for faster removal of vials for placement onto dry ice or liquid nitrogen.
