<p>A spreader, movable over a base, coats a microscope slide or the like mounted on the base with a single uniform layer of a fluid. The spreader comprises a platform having legs and pressure pads for supporting the platform above the slide and a bar on the lower surface of the platform for uniformly spreading the fluid to create a monolayered film on the upper surface of the slide as the spreader is drawn over the slide. Ramps are provided in tracks of the base to permit the bar to evenly disengage from contact with the film.</p> |
