Abstract
A mold is disclosed for forming a freezable and thawable bag of uniform thickness, especially useful for cryopreservation of thermolabile substances. The mold features one or more recessed planar surfaces, including radiused peripheral walls about the recesses, a planar top surface, and means for conforming a blank sheet to the mold. Two mold halves combine to form a completed bag. The mold halves may be complimentary.
