A sealed container having gloves attached thereto is provided as part of a physical properties measuring system (PPMS). The PPMS includes a sealed pressurized portion that is pressurized with a gas to purge out air from inside the sealed pressurized portion to reduce water vapor inside the sealed pressurized portion below a water vapor threshold. The system further includes a cryogenic tank having a cryostat disposed therein. The cryogenic tank contains a cryogenic liquid cooled to a cryogenic temperature. Test samples are placed inside the sealed pressurized portion in preparation of measuring physical properties of the test samples. One of the test samples is immersed in the cryogenic liquid to measure the physical properties. The test sample is removed from the cryogenic liquid and is exchanged for another test sample inside the sealed pressurized portion to prevent ice formation inside the cryostat.
