The Cryo Chiller is a Single Middeck Locker Equivalent sized payload facility designed for use aboard the ISS for rapid freezing of biological samples in the EXPRESS Rack. Cryo Chiller provides rapid-freeze capability by taking advantage of the designs and lessons learned from current ISS cold stowage assets, including Glacier, MERLIN, and Polar. 

The Rapid Freeze units excel in cooling a 25ml sample to -95 C in less than 60 seconds. There are several sample options offered from 10ml vials to tissue slides. Cryo Chiller is the largest of the rapid freeze units and offers the largest sample volume and sample cartridge options.

The sample cartridges are a key component for rapidly cooling research specimens within the Cryo Chiller. They are made of low-alloy, high conductivity copper and are interchangeable based on the requirements of a given experiment.

Rapid Freeze Ground Control Units are also available to interested principal investigators for both pre-mission experiment optimization and simultaneous ground control studies that can performed side-by-side with their research conducted aboard the ISS.
