Rapid Freeze Patch 

The Glovebox Freezer is a portable payload facility designed for rapid freezing of biological samples aboard the International Space Station (ISS) in the Microgravity Sciences Glovebox (MSG) or Life Sciences Glovebox (LSG).  The Glovebox freezer has a planned launch on SpaceX-16 later this year and is expected to reside on the ISS indefinitely.

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. The GloveBox Freezer is the most compact of the units and comprises of two main components. By breaking out the water cooled system from the unit , we are able to compress down the area into which the actual insertion part of the unit can fit. This is perfect for cryogenically freezing the small samples from a contained experiment. Once frozen, none of the molecules move, this prevents decay and warping in the structure of the sample. Once the science arrives back on earth it is exactly how it was on the International Space Station.

The custom made pure copper insert is a key component for rapidly cooling the samples. The copper may weigh over 50 lbs on Earth, but on the International Space Station weigh less than a feather. The inserts are interchangeable based on the experiment, so the researcher must choose the best fit for their experiment.
