Patent ID: 8651327

Claim:
A system for storing biopharmaceutical materials, said system comprising: a plurality of flexible walls bounding an interior of a container for holding biopharmaceutical materials therein; at least one port connected to a first wall of said walls and providing fluid communication between said interior and an exterior to allow a draining of said interior; and a collapsible conduit having a plurality of perforations along said conduit, said plurality of perforations configured to allow a flow of the biopharmaceutical materials from the exterior to the interior of said conduit; said conduit having a cross sectional area transverse to a length of said conduit, and said conduit extending from one of said at least one port toward an opposite end of said interior; said conduit being collapsible by said flexible walls and forming a reduced cross sectional area when said container is drained to allow a flow of the biopharmaceutical materials through and/or along said conduit to said port said conduit comprising a first interior surface facing a second interior surface about an interior of said conduit, said first surface and said second surface contacting each other across a width of said conduit upon being flattened by the draining of said container, the flattening of the conduit minimizing a hold up volume of the conduit.
