CoolBox CFT30 System eliminates the risk of ice contamination and provides hours of ice-free cooling or freezing for 1.0 or 2.0 mL cryogenic vials, with consistent and uniform well-to-well temperature. The contoured well design of the CoolRack CFT30 cryogenic vial module "grips" each vial and allows one-hand opening and closing, further minimizing contact with the vials that may result in temperature fluctuations.
Each system comes with a highly insulative and durable HDPE base and lid, one cooling cartridge that is comprised of a phase-change solution in a thermo-conductive housing, and a CoolRack CFT30 module to hold up to 30 1.5 or 2.0 mL cryogenic vials. Also included is an insulator pad to protect the exposed surface of the CoolRack CFT30 module from ambient temperature for maximum cooling duration.
Available in purple only.
Temperature and duration:
+0.5℃ to 4℃: Use blue cooling cartridge to keep samples cold for up to six hours with lid off, up to 10 hours with lid on
-18℃ to -10℃: Use green freezing cartridge to keep samples frozen for up to four hours with lid off, up to 6 hours with lid on
-30℃ to -25℃: Place dry ice in the bottom of CoolBox 30 base. Cover the dry ice with the insulator pad and then rest CoolRack tube module on the insulator pad for up to 5 hours of freezing.
CoolBox 30 is compatible with dry ice and liquid nitrogen and either may be used in place of the cooling cartridge to provide ultra-low cooling (snap freezing).
