A spreader, movable over a base, coats a microscope slide or the like mounted on a supporting surface of the base with a single uniform layer of a fluid. The spreader comprises a support having legs for engaging the supporting surface, pressure pads for engaging the slide to hold the support above the slide having a fluid thereon, and a bar extending transversely along the lower surface of the support having a flat section and a cutaway section for uniformly spreading the fluid to create a monolayered film on the upper surface of the slide as the spreader is moved in a longitudinal direction along the length of the slide. The flat section and the cutaway section are maintain parallel to the slide and sloped surfaces extend upwardly in the longitudinal direction from the flat section and the cutaway section toward the support. Ramps are provided in tracks of the base to permit the bar to evenly disengage from contact with the film.
