Cryostat:
The word cryostat is a word of compound meaning from the roots cryo, which means cold, and stat, which means static or stationary. A cryostat is an instrument used to sustain very low temperatures at -238 degrees Fahrenheit (-150 Celsius) or below, for many medical, engineering, and scientific uses. The chemicals to maintain these temperatures are baths of liquid helium for tissue specimens or liquid nitrogen for cryonics patients. The inner vessel of a cryostat is similar in construction to a vacuum flask; and there is a precision cutting instrument for sectioning tissues known as a microtome inside the freezer portion of the cryostat.

Noted in “Quantum device detects all units of electricity at once,” Karmela Padavic-Callaghan, NewScientist (30 August 2025, paywall):
This integration was challenging because both devices rely on fragile quantum phenomena that can only be observed at very low temperatures – so low they must be operated in special fridges called cryostats. Traditionally, one device also required a magnetic field that disrupted the operation of the other.
Yeah, that entire title just left me baffled, and the content was no help.
