ABSTRACT:
An apparatus to lyophilize, store, transport, rehydrate, and process aqueous biological materials in a container which maintains sterility of its contents, allows container shrinkage after lyophilization, and optimally permits filtration or dialysis of the contents in situ, without the need for a second or series of additional containers. These benefits are met by a microporous container constructed of a membrane that is water vapor permeable, yet water impermeable.
