ABSTRACT:
A filtration cassette is described. The filtration cassette can include one or more filtrate channel spacers and one or more feed channel spacers. Each of the feed channel spacers and each of the filtrate channel spacers define an open interior volume bounded by an inner perimeter and include at least one feed port and at least one filtrate port. The filtrate channel spacers and the feed channel spacers are arranged such that the feed ports and the filtrate ports are positioned in respective alignment. The filtration cassette further includes one or more membranes disposed between the filtrate channel spacers and the feed channel spacers, and one or more retaining members at either end of the filtration cassette. A thin film of adhesive binds together the filtrate channel spacers, the feed channel spacers, and the membranes.
