  • Patent number: 8926923
    Abstract: The present invention relates to pharmaceutical fluids, and more particularly to a flexible container for aseptic transfer and/or mixing of pharmaceutical fluids. A biocontainer for the transfer of pharmaceutical fluids includes a flexible layer divided by a fold line into a front face and a rear face. The layer is folded about the fold line such that the front face and the rear face are facing each other to define an interior space between them. The biocontainer also includes a seam that connects the front and rear faces to each other to close the interior space. A fill port is also provided to communicate with the interior space. This fill port is intersected by the fold line.

  • Patent number: 6734386
    Abstract: A microporous PVDF membrane is rendered hydrophilic without making it brittle or lowering its heat resistance by exposing the membrane to a plasma under controlled conditions. Specifically, a microporous PVDF membrane is first coated with an appropriate monomer. After the monomer dries, the membrane is exposed to the plasma. Any remaining uncured monomer on the membrane is removed. Thereafter, the membrane is pleated and incorporated in a filter cartridge.
