Patent ID: 8287822

Claim:
A reaction surface array diagnostic apparatus comprising: a single stack including a planar substrate; a plate having a plurality of wells extending therethrough disposed in a standard microtitre plate well spacing; a gasket, having a releasably adhering surface, sealingly coupling the plate to the planar substrate, the gasket having wells disposed in said microtitre plate well spacing and fluidically coupled to the wells in the plate and combining with the wells in the plate to form reaction chambers disposed in said microtitre plate well spacing, the substrate forming a bottom of the wells, and wherein the gasket is positioned between the plate and the planar substrate, and where the gasket has a first face contiguous with the plate and a second face contiguous with the planar substrate; and a pair of joinder members engageable with longer side edges of the stack, the pair of joinder members providing a clamping force to the longer side edges of the stack and extending inboard of the longer side edges of the stack on a top surface of the plate, wherein the wells of the plate are exposed when the stack is clamped by the pair of joinder members.
