CRYOGENIC STORAGE CONTAINER

摘要

This cryogenic storage container has peripheral walls defining a storage cavity. The storage cavity has an access opening closed by a closure. A cryogenic freezing unit is provided whereby the storage cavity is cooled. The characterizing feature of the storage container is that the peripheral walls and closure are of multi-layered construction. More particulary, the layers include: an inner plastic liner; a cloth layer; a first insulation layer; a plywood layer; a second insulation layer; a reflective foil layer; and an outer protective shell. The cloth layer is impregnated with carbon and coated on at least one side by urethane. The plywood layer is made of a hardwood. The reflective layer has a reflective surface oriented inwardly toward the plastic liner.
