The Int'l Space Station has a -80Â° C laboratory freezer
The Minus Eighty (Degrees Celsius) Laboratory Freezer for ISS (MELFI) helps provide the Space Station with refrigerated volume for storage and fast-freezing of life science and biological samples. The freezer, which has a total capacity of 300 litres, works using very pure nitrogen as the working fluid. The temperature is continuously monitored and recorded even in power-off phases.
