Abstract
Containers () for cryopreserved biological samples () may include an insulated housing including a cavity () for containing at least one cryopreserved biological sample; and a sealed reservoir () at least partly surrounding the cavity, the sealed reservoir including liquified gas () such as liquified air, the gas being kept largely liquified by a heat transfer engine () such as a Stirling cryocooler. A valve () may be provided to function as both a pressure relief valve and an inlet valve. The inlet valve may be coupled to a sensor () for sensing a volume of liquified gas within the sealed reservoir. The container may further include a heat exchanger () coupled to the heat engine and extending into the sealed reservoir.
