  • Flask vent and method of making same
    Patent number: 6193088
    Abstract: A closure (20) for sealing a micro-organism container (50) is disclosed. The closure (20) includes a resilient seal (24) for sealing the container (50), a passageway (26) extending through the seal (24), or filter media (28) extending across the passageway (26) integrally molded to the seal (24) for allowing sterile gas exchange therethrough. A method of making a flask closure (20) is also disclosed. The method includes molding a sealing member (24) having a port (26) extending therethrough while simultaneously sealing a peripheral edge (31) of a filter media (28) within the passageway (26).
    Type: Grant

  • Fluid filter assembly
    Patent number: 5348646
    Abstract: A filter assembly (10) includes a hollow housing (12) having a length and first and second ends (14,16). A membrane (22) contained within and extending along the length of the housing (12) separates the housing (12) into first and second chambers (24,26). An inlet (32) is proximate to the first end (14) and is in fluid communication with the first chamber (24). An outlet (34) is proximate to the second end (16) and is in fluid communication with the second chamber (26) for allowing a flow of fluid from the second chamber (26). The membrane (22) is air permeable when dry and air impermeable when wet whereby a wetting fluid entering the first chamber (24) at the first end of the housing (12) forces air from the first and second chambers (24,26) along the length of the membrane (22) and out of the outlet (34) as the fluid wets the membrane (22) thereby de-airing the first and second chambers (24,26) from one end to the other end along the length of the membrane (22) on both sides thereof.
