ESA project astronaut Sławosz Uznański-Wiśniewski uses one of ESA’s space freezers during his stay on the International Space Station (ISS).
The European space freezers are called MELFI, acronym for Minus Eighty-Degree Laboratory Freezer for ISS. European astronauts use them to keep samples like urine, blood or saliva cold. Their temperature is typically set at around –90°C, so astronauts need gloves to operate them.
