Abstract:
Containers (100) for cryopreserved biological samples (102) may include an insulated housing including a cavity (108) for containing at least one cryopreserved biological sample; and a sealed reservoir (106) at least partly surrounding the cavity, the sealed reservoir including liquified gas (120) such as liquified air, the gas being kept largely liquified by a heat transfer engine (112) such as a Stirling cryocooler. A valve (114) may be provided to function as both a pressure relief valve and an inlet valve. The inlet valve may be coupled to a sensor (122) for sensing a volume of liquified gas within the sealed reservoir. The container may further include a heat exchanger (116) coupled to the heat engine and extending into the sealed reservoir.
