Abstract
A cryogenic freezer and a method of controlling temperature within the cryogenic freezer. The cryogenic freezer includes an inner vessel. The inner vessel defines a storage chamber. The cryogenic freezer includes an outer vessel surrounding the inner vessel. The outer vessel may define a vacuum-insulated space in between the outer vessel and the inner vessel. The cryogenic freezer includes a temperature sensor configured to measure a temperature within the storage chamber. The cryogenic freezer includes a controller coupled to the temperature sensor. The controller is configured to pulse an amount of cryogen into the storage container to control the temperature within the storage container.
