A Simple Device for Washing Large Numbers of Sections and Tissues

A simple, efficient, and inexpensive device which washes up to 480 slides simultaneously, is described. It consists essentially of a deeper lower tray to hold the slides or specimens and a shallower upper tray which distributes the water. Both are held in place by wooden frames. Both trays are perforated and the tapwater flow into the upper one is adjusted to keep the lower one nearly full. The correct number of holes needed in the bottom of each tray to maintain equilibrium of flow is ascertained easily by trial.
