  • Vacuum filter assembly
    Patent number: 5141639
    Abstract: A vacuum filter assembly for filtering a feed liquid includes a filter membrane held in a cover attachable to the filtrate container. The cover is formed with a feed liquid nipple on one side of the filter membrane, a filtrate outlet tube on the other side of the filter body, and a vacuum port. A portion of the surface of the membrane is non-wettable by the feed liquid to facilitate restarting the filtration if the filtration is interrupted. Also, the vacuum port includes a vacuum tube covered at its end by another membrane having pores permeable by air but not by the feed liquid, for fixing the maximum level of the filtrate within the filtrate container.
