Protocols
Controlled-Rate Cell Cryopreservation
CoolCell® delivers consistent freezing profiles to all cryogenic tubes and each freeze batch. Consistent results ensure successful cryopreservation and reproducibly high post-thaw cell viability and function. CoolRack®, CoolBox™, and ThermalTray™ also aid in maintaining sterility during the sample preparation and thawing processes.

Controlled-Rate Cell Cryopreservation Using a Dry Ice Locker
When a -80°C freezer isn't available, the CoolCell® cell freezing systems can be successfully used in a dry ice locker to achieve reproducible and viable cell freezing. See testimonial below:

General Snap-Freezing
Snap-freezing with a CoolRack® or CoolSink™ thermo-conductive module provides an efficient, alcohol-free and highly reproducible method. The properties of the alloy material ensure each sample tube or well experiences the same temperature profile - whether on dry ice or in liquid nitrogen. See performance data for information on snap-freezing rates and standard deviation reduction when using a CoolRack compared to directly inserting tubes into dry ice, dry ice / alcohol baths or liquid nitrogen.

Virus Cryopreservation
Freezing viral samples with a pre-cooled CoolRack® ensures rapid, consistent and reproducible freezing. The CoolRack method is a safe and efficient replacement to the dry-ice/alcohol slurry freezing method - eliminating the risks of contamination and variation in molecular integrity, while still producing high virus titer levels .

Bacteria Cryopreservation
Freezing bacterial samples with a pre-cooled CoolRack® ensures rapid, consistent and reproducible freezing. The CoolRack method is a safe and efficient replacement to the dry-ice/alcohol slurry freezing method - eliminating the risks of contamination and variation in molecular integrity, while still producing high bacteria titer levels.

Application Notes
Ice-Free Cooling and Freezing
CoolRack® tube modules and CoolSink™ plate modules can be used in the ice-free CoolBox Systems for hours of benchtop ice-free cooling and freezing. Reusable cartridges ensure sample temperature uniformity - no edge effect - in a compact workspace. Highly durable and versatile.

Incubating and Thawing in a Water Bath
CoolRack® tube modules and CoolSink™ plate modules may be placed on a ThermalTray™ platform for use in a water bath. Ensure tubes and plates stay at desired temperature, but eliminate risks associated with direct water contact.
