Ice-free cell preparation: The XT Starter ice-free cooling base and CoolRack SV10 vial module (photo right) provide up to 4 hours of ice-free cooling (0.5 to 4.0°C) for cell and cryoprotectant preparation. Simply freeze the XT Starter core in a -20°C freezer and then rest the thermo-conductive CoolRack SV10 on top. The system will equilibrate to approximately 2°C and keep all samples uniformly cold and free of ice contamination. The small footprint and low profile make this an ideal cooling solution for cell preparation performed in a tissue culture hood.

Controlled-rate cell freezing: The CoolCell SV10 cell freezing container (photo left) provides highly reproducible -1°/minute freezing rate for cells when cryopreserved in a -80° freezer. No programming or alcohol is required - simply place in a -80°C freezer. 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.
