Cryogenic equipment can sustain extremely low temperatures, generally below −150 °C.

Medical laboratories use equipment called cryostats to sustain frozen tissue specimens while a microtome, a very sharp cutting tool, slices the tissue for viewing under a microscope. A doctor or researcher can then investigate the slices to verify or rule out the presence of a disease, like cancer.

Frozen tissue specimens allow physicians to study tissue and detect its condition faster than if the tissue had been conserved without freezing.
