ABSTRACT:
A membrane holder for use with a diagnostic device comprises an interlocking first plate and a second plate. The first plate has a top surface flush with a hole, while the bottom surface defines a raised ring, a projection in one corner and an orifice in another corner. The second plate has a top surface having a recess for accepting a membrane, within which is a hole and ribs emanating outwardly to a raised circular rib from which a recessed ring emmanates. The recessed ring of the second plate is adapted to accept the raised ring of the first plate. The top surface of the second plate further has a projection in one corner and an orifice in another corner which mate with those in the first plate. The bottom surface of the second plate has a member to guide liquid away from the membrane. To assemble, a membrane is placed in the recess on the top surface of the second plate. Then, the raised ring on the bottom surface of the first plate is placed over the recessed ring on the top surface of the second plate, and the projection and orifice of the first plate is set to mate with the orifice and projection of the second plate. The plates are then snapped into place, as the orifice and projection each fit within the other, respectively. The raised ring interlocks with the recess, pulling taught the membrane positioned therebetween. Once assembled, the membrane holder may be placed on top of a testing conduit and an assay may be performed on the membrane.
