ABSTRACT:
To eliminate welds when forming connections from coupling joints of membrane filter structures having two external housing plates between which a membrane filter assembly (3, 4) is positioned, one (2) of the housing plates (1, 2) is formed with a bored or milled, essentially circular recess at each one of the locations where fluid connection couplings (6-9) are to be placed, the fluid connection couplings being formed by a plug element which is clamped in sealing engagement against a sealing bottom wall surface (13) of the respective recess. To provide absolute tightness, even of molecular substances such as bacteria, tissue elements, yeasts and the like, a sealing ring, preferably an O ring (15) is placed in a groove (14) formed in the sealing wall surface (13).
