Abstract: The present invention relates to the formation of a gasket, sealing area or O-ring, such as a gasket on a screen for a filtration module such as a TFF or NF cassette or an O-ring on the outlet of a filter catridge wherein the seal is proud of at least one surface of the screen. Preferably, the seal is molded to the filter component. more preferably it is injection molded to the component. The seal may be formed of any elastomeric material such as thermoplastic, thermoplastic elastomers, thermosets and rubber, both natural and synthetic. The molded seal provides better sealing, allows for a variation in heights and geometries, and provides better cleanliness and lower extractables than the currently used adhesives or conventional gaskets or O-rings.

Abstract: A manifold adaptor plate useful as a gasket having liquid pathways which permit passing of a filtrate, a feed and a retentate wherein admixture of the filtrate with the feed or the retentate is prevented is provided and is formed of an elastomeric layer, a rigid intermediate layer and a polymer layer. The elastomeric layer functions as a gasket and is bonded to the polymeric layer through the liquid pathways of the intermediate plate. An elastomer layer may be formed on both layers as well and optionally a second polymer layer between the intermediate layer and the second elastomer layer may also be used.
