The counting chamber is a simple-to-use device for rapid and accurate sperm count, motility and morphology evaluation, from undiluted specimen.
The chamber is composed of two parts:
The lower part has a metal base and two handles. In the center of the base there is a flat disc made of optical flat glass on which the sample is placed.
The upper part is the cover glass encircled with a metal ring. At the center of its lower surface there is a 1mm2 grid, subdivided into 100 squares, each one of 0.1 x 0.1 mm.
When the cover glass is placed on the four tips, the space bounded in a row of 10 squares is exactly one millionth of mL. Therefore, the number of sperm heads in 10 squares indicates their concentration in million/mL.
