Abstract
A portable cryogenic container includes a porous material configured to absorb a cryogenic coolant such as liquid nitrogen. The coolant-absorbing material at least partially defines a storage cavity in the container that is configured to accept and support a cassette or other type of contents container in which a product to be cryogenically stored is contained. With cryogenic coolant absorbed into the container, the temperature within the storage cavity can be maintained sufficiently close to the boiling point of the cryogenic coolant to preserve post-thaw viability of the stored product for several hours.
Claims21
A cryogenic storage container, comprising one or more walls that together define a closable storage cavity, wherein at least one of the walls comprises a layer of porous material configured to absorb a cryogenic coolant and to release the cryogenic coolant in vapor form into the storage cavity,
- wherein the porous material lines the storage cavity and is a non-polymeric material having an open-cell structure in which pores are interconnected throughout the material.
A method of cryogenically storing a product, comprising the step of housing the product in a storage cavity of a portable storage container comprising a liquid cryogenic coolant absorbed by a non-polymeric porous wall that lines the storage cavity and releases the cryogenic coolant in vapor form into the storage cavity.
