A cryogenic storage system for cryogenic storage using liquid refrigerant is provided. The cryogenic storage system includes first and second vacuum vessels, a vacuum source, a quantity of a liquid refrigerant, and at least one temperature control assembly. An insulating wall may be provided on an interior surface of one of the vessels. A common vacuum condition is provided in voids that are present in the wall of the first and second vessels as well as in the insulating wall. The at least one temperature control assembly includes a power supply, a temperature sensor, a heater, and a conductive element. The at least one conductive element provides a link or thermal coupling between a space defined in the first vessel and the liquid refrigerant stored in the second vessel.

Cryogenic storage system with improved temperature control

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 cryogenic temperature. The devices include a temperature chamber defined by a thermally-conductive container and at least one layer of thermal insulation surrounding the thermally-conductive container. Some embodiments utilize one or more heat sources thermally connected to the thermally conductive container. Other embodiments are arranged so that no net flow of heat occurs from the temperature chamber when the temperature chamber is at a set target temperature. Also provided are methods of using the devices.
