The present invention provides devices and methods for the cryogenic storage of biological material. Devices of the invention are useful for storing material at a predetermined cryogenic temperature. An intermediate storage chamber (ITC) set within an adiabatic Dewar container includes a set, or multiple, heat transfer pipes that passively act to maintain a set temperature or temperature range. Some embodiments utilize an inner heat pipe to transfer heat out to a heat sink and an outer heat pipe to transfer heat into the ITC from a cool sink. The heat pipes may be arranged, designed, and/or tilled to conduct heat energy only when set parameters beyond the predetermined range are experienced within the ITC. The method of maintaining a predetermined temperature range by means of a heat sink and cool sink are taught herein.
A method for passively maintaining the temperature in a cryogenic chamber within a predetermined temperature range between a low temperature threshold and a high temperature threshold, said method comprising the steps of:
A method for passively maintaining the temperature in a cryogenic chamber within as predetermined temperature range between a low temperature threshold of no lower than 100K and a high temperature threshold of no higher than 170K, said method comprising the steps of:
