Claim 5:
6. The vertical flow detection device of claim 1 configured to accommodate bi-directional flow, the device further comprising:
a top and a bottom diffuser membrane with the membrane provided between the top and bottom diffuser membrane;
an additional rigid porous membrane to provide a first rigid porous membrane support and a second rigid porous membrane support, wherein the first rigid porous membrane is adjacent to an exposed surface of the top diffuser membrane and the second rigid porous membrane support is adjacent to an exposed surface of the second diffuser membrane;
a first gasket integrated with the first rigid porous membrane support and a second gasket integrated with the second rigid porous membrane support to provide additional support and sealing, including two gaskets for each surface of the rigid supports to provide sealing with the membranes and holder to make sure all fluid passes the center area of the membranes, and, optionally, wherein the gaskets are integrated with the rigid supports;
wherein the top and bottom diffuser membranes provide a relatively uniform flow through the membrane, including the membrane first surface having capture agent immobilized thereto.
