Patent ID: 7736594

Claim:
A reaction surface array diagnostic apparatus comprising: a stack, the stack including a planar substrate with a plurality of reaction surfaces predeposited in bound arrays on the 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 to form the stack, 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 about the reaction surfaces on the planar substrate; and first and second joinder members each engageable with substantially an entire length of side edges of the stack, each of the joinder members engageable with the side edges at both a top and bottom of the stack adjacent to side walls of the plate, each of the joinder members forming a first channel with a top portion, a bottom portion, and a central portion, with the top portion of the first channel extending outwardly from the central portion, the top portion engageable along the entire length at the top of the stack, the bottom portion of the first channel extending outwardly from the central portion and engageable along the entire length at the bottom of the stack, each joinder member is formed as an I-shaped member.
