CoolBox™ ice-free cooling and freezing systems provide hours of benchtop cooling or freezing through the use of reusable cartridges. The thermo-conductive housing of the cartridge and the alloy of the CoolRack® tube/plate module efficiently transfer heat from the samples and evenly distribute the cooling/freezing temperature to all tube or plate wells.

Uniform well-to-well temperature (no "edge effect") sets CoolBox™ apart from other ice-free coolers. All wells remain within +/-1.0℃ of each other, regardless of the flatness of the plate's bottom surface, removing temperature variability from the sample set and providing a highly reproducible method of keeping samples cold without ice on the bench, in the biosafety cabinet, or during short transport.

· Constructed out of highly durable cross-linked dense polyethylene foam

· Cooling and freezing cartridges are compact and can be frozen and stored in a -20℃ freezer

· To extend cooling or freezing, replace spent cartridge in the CoolBox with a frozen one from the freezer

· Clean with aqueous detergents, alcohol, bleach or acid/base viricides

· Excellent resistance to fluid absorption, surface abrasion, and rust

· For labeling, use BioCision CryoLabels #BCS-168. Repeated application and removal of labels will not affect surface.

· Made in USA

Use also with dry ice or liquid nitrogen for snap-freezing in a compact benchtop workstation. Temperature and duration (using ice-free cartridges as cooling source):

· +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 (CoolBox 30 only)

Temperature and duration (using dry ice or liquid nitrogen as cooling source):

· -30℃ to -25℃: Place dry ice in the bottom of CoolBox instead of using a reusable cartridge. Cover the dry ice with insulator pad. Then rest CoolRack tube module on the insulator pad for up to five hours of freezing. (CoolBox 30 only)

· -78℃: Place dry ice in the bottom of CoolBox instead of the reusable cartridge. Rest CoolRack or CoolSink module directly onto the dry ice for up to six hours of cryogenic temperature.

· -150℃: Place a small CoolRack (6 or 15 tube wells) on the bottom of the CoolBox and surround with liquid nitrogen. Maintain LN2 midway up the side of the CoolRack for hours of ultralow freezing temperature.
