Polar (refrigerator)

Polar is a research refrigerator designed and developed by University of Alabama at Birmingham (UAB) Center for Biophysical Sciences and Engineering (CBSE) for NASA Cold Stowage. Polar was designed as a single mid-deck locker equivalent[further explanation needed] payload to store scientific samples on-board ISS and in transport to/from ISS via SpaceX Dragon or Cygnus spacecraft. Polar operates between 4 and −95 °C (39 and −139 °F).[1][2]

## Description

* Polar is mounted in the ISS on the EXpedite the PRocessing of Experiments to Space Station (EXPRESS) rack.
* Polar can maintain temperatures ranging from 4 to −95 °C (39 to −139 °F).
* Polar is air-cooled via rear-air fan.

## Additional Cold Stowage

Polar is one of multiple units available for storage on the ISS and/or transportation to and from the ISS. Others include:

* Minus Eighty Degree Laboratory Freezer for ISS (MELFI)
* 4 to −80 °C (39 to −112 °F)
* MERLIN (Microgravity Experiment Research Locker/ Incubator)
* 48 to −20 °C (118 to −4 °F)
* GLACIER (General Laboratory Active Cryogenic ISS Experiment Refrigerator)
* 4 to −160 °C (39 to −256 °F)
