Abstract
A microscope inspection slide including at least one examination chamber formed by bonding together a base plate and a cover plate. The base plate having a chamber floor surface raised above a deck surface on the base plate, and the cover plate having a roof surface with a depth control ridge positioned about a portion of the edge of the chamber roof surface. Bonding the cover plate to the base plate forms an examination chamber with the distance between the roof surface and floor surface maintained constant, and entrapped gases and excess fluid allowed to drain from the examination chamber through notches in the depth control ridge.
