Abstract
Apparatus and methods for controlling the fluid on a slide are provided. Fluid reduction is accomplished by directing stream(s) of fluid at an edge of the slide, the streams of fluid being at an angle with the slide of less than 90°. The surface tension at the edge of the slide is broken by the stream(s). And, the fluid which is on the slide is drawn or pulled by the streams of liquid, thereby reducing the fluid on the slide to a reproducible, consistent level.
