Sedgewick rafter counting cell

The Sedgewick Rafter chamber is constructed as a flat slide (76mm x 40mm) onto which is cemented a ‘wall’ to form a chamber or cell in the middle. This chamber is 50mm long x 20mm wide and 1mm deep and its base is marked with a grid of 100 x 1mm squares. When filled with liquid and with a cover glass placed over the chamber a 1ml volume of liquid is trapped. When used under a low magnification light microscope, each of the grid squares equates to 1 microlitre of liquid.
