(hē'mō-sī-tom'ĕ-tĕr)
An apparatus for estimating the number of blood cells in a quantitatively measured volume of blood; consists of a glass pipette with an ampulla for collecting and diluting the blood, and a counting chamber marked in squares.
Synonym(s): hemacytometer, haemocytometer.

haemocytometer

A glass plate accurately engraved with a grid of squares on which a thin film of blood is allowed to spread so that cell counts can be done under the microscope. Also known as a counting chamber.

haemocytometer

an instrument used to determine cell or spore counts. It consists of a grid etched on a glass block; the grid is usually of sides 1 mm, and is divided into 400 squares, each 0.0025mm2, in which the cells are counted under a microscope.
