First Claim
Patent Images
1. An integrated container to lyophilize, store, transport, rehydrate, and process biological materials, comprising:
- a) a closed construct, said closed construct defining a cavity therein, said cavity further comprising a lyophilization compartment having an upper face and a lower face and four lateral faces, wherein said upper face is fabricated with a flexible controlled pore membrane with hydrophobic surfaces that allows passage of water in a vapor but not liquid state, said lower face is fabricated with a rigid material, and said lateral faces are fabricated with a flexible material capable of maintaining a barrier between an internal vacuum and the external atmosphere; and
b) one of four said lateral faces having an access port therein to allow entry or removal of biological or other materials and water, said access port having a barrier to maintain sterility.

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.
