Abstract: A transparent laboratory slide for wet mount microscopic examination. A base member is formed with discrete platform surfaces or slide plates over which a cover slip is removably positioned. The fluid specimen to be examined is retained in the thin space between the platform surface and the cover slip by a capillary action. Peg and socket interconnecting means provide precise spacing between the platform and the cover slip. The platform surface is raised from the bottom wall of the base and the sides of the platform are opened to the external environment. This slide conveniently provides for low power and high power magnification as well as increased magnification by means of oil immersion.
