A culture dish for use in in vitro cell manipulation has an outer rim encompassing, and at right angles to, the periphery of the working surface. A parallel inner wall, spaced from the outer rim, forms a trough along the periphery of the dish. Preferably the outer rim is higher than the inner wall to permit liquid contents to flow into, and be retained within, the trough. Cell indices are etched into the working surface to identify the cell location. Although the dish can be solid or translucent, in most applications the working surface is transparent. The cell indicators can optionally be etched into the bottom side of the working surface to maintain a smooth top surface. A working circle, with a periphery smaller than the inner wall, is inset into the surface of the working surface. Alternatively, the circle can be etched into either the top or bottom side of the surface. A lid can be used in conjunction with the culture dish for storage purposes.
