Abstract
A filtration apparatus for deadend filtration is provided which is formed from multilayer presealed elements and monolayer elements that are insert molded together. The device is provided with a feed port, and a filtrate port. The sealing configuration of the presealed elements and the seal provided by the insert molding step effect a seal configuration that causes a feed liquid to be filtered to form a filtrate such that the filtrate is not mixed with the feed.
