Abstract: A cryogenic specimen shipping container using nitrogen gas for transport of a cryogenic specimen to a cryogenic storage chamber or Dewar vessel for storage. The cryogenic specimen shipping container may comprise an outer container, an inner container received within the outer container, and a gas pathway located between the outer container and the inner container and configured to expel the nitrogen gas.

Abstract: 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 filled 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.
