The Counting Chamber is of all glass construction. In the center of the slide is a rectangle 15 x 20 mm, which is flanked by shoulders on each side 0.1mm higher. The cover glass is supported on these shoulders and leaves a depth of 0.1mm between the underside of the cover glass and the rectangle. The rectangle and the cover glass have optically plane surfaces. To facilitate calibration of the microscope, the rectangle has two engraved parallel lines spaced 1.382mm apart.An accessory eyepiece micrometer is available which is ruled into squares, each of which is equal to 1/6 of the diameter of the eyepiece diaphragm opening. For mold counting, the microscope must give an area of 1.5 sq. mm.(circle 1.382 mm in diameter) at magnification of 90-125.

Occasionally a blended mixture will contain particles of seed tissue that make it difficult to obtain Newton rings in preparing slide for mold counting. A clamp devised for holding cover slip in place to obviate this difficulty consists of metal plate with circular opening, 2.5 cm in diameter, in center of plate; 2 clips attached to anterior edge of plate fasten cover slip in position when slide is placed on plate.To clean the counting chamber: After completing the count, remove the cover glass and clean the counting chamber with water or a mild cleaning solution (10% solution of bleach). Dry the counting chamber with a soft cloth or wipe, or rinse with acetone.
