1. An array hybridization apparatus, comprising:
- (a) a slide for holding an array;
(b) a substrate opposite said slide for acting as a backing for said array hybridization apparatus;
(c) a gasket interposed between said slide and said substrate; and
(d) a spacer interposed between said slide and said substrate and adjacent to said gasket wherein an array hybridization chamber of uniform height is defined between said slide, said substrate, said gasket and said spacer when said slide and said substrate contact said gasket and said spacer.

Abstract
An apparatus and method for making array hybridization chambers with uniform sample volumes. The apparatus employs a spacer to define a hybridization chamber of uniform volume between a slide, substrate, and gasket after the slide, substrate, spacer and gasket have been contacted. The spacer is non deformable or partially deformable and will only allow the adjacent gasket to a similar height or volume. Methods of making the hybridization apparatus and chambers are also disclosed.
