  • Patent number: 6996995
    Abstract: The present invention provides a system for freezing, thawing, and storing biopharmaceutical materials which includes a flexible container, a conduit, and a temperature control unit. The flexible container is adapted to receive a biopharmaceutical material therein for freezing, thawing, and storing. The container is formed of a first substantially flat sheet of flexible material joined together by a seam with a second substantially flat sheet of flexible material so as to lie substantially flat when empty. The container fully encloses an interior portion for receiving the biopharmaceutical material. Also, the container is configured to form a three dimensional shape when filled with the biopharmaceutical material, wherein the three dimensional shape has a first side and a second side opposite the first side. The conduit is connected to the flexible container with the outside of the container being in fluid communication with the interior portion via the conduit.
