Abstract
A fluid path control element which when stacked alternatively with a fluid porous sheet can be formed into a filtration module. The fluid path control element comprises a porous membrane having sealed to a portion of its periphery a thermoplastic element that extends into an opening either through the membrane or in an opening through the thermoplastic element. The portion of the thermoplastic element that extends into the opening can be heat sealed with a second thermoplastic element to prevent fluid flow between the opening and the membrane.
