Abstract: A container includes an inner bag, where the interior of the inner bag includes a sterile environment for storing a material, at least one access port configured to provide fluid access to the interior of the inner bag, an overwrap bag, where the interior of the overwrap bag includes a sterile environment for storing the material and where the inner bag is enclosed within the interior of the overwrap bag, and an overwrap access port configured to provide fluid access to the interior of the overwrap bag. The material can include a biomaterial. Each of the inner bag, the overwrap bag, the at least one access port, and the overwrap access port can include a fluoropolymer such as fluoroethylenepropylene (FEP).

Abstract: A closed system for withdrawing, measuring, and isolating discrete quantities of liquid specimen for cryogenic preservation and recovery includes a fluoroplastic storage tube, an aspirating device, such as a syringe, and an impermeable barrier. The aspirating device can be used to meter exact amounts of specimen into the tube, and then to isolate the specimen within the confines of the tube during freezing, storage, thawing. The specimen in the tube can be withdrawn into the same syringe. While encapsulated, the specimen is protected from contact with air, gasses, and moisture in the cryogenic atmosphere. The specimen can be recovered from the frozen state without compromising sterility or exposure to any external environment.
