What is a counting chamber used for?
A device used for determining the number of cells per unit volume of a suspension is called a counting chamber. The most widely used type of chamber is called a hemocytometer, since it was originally designed for performing blood cell counts.
What was the hemacytometer originally created for?
patient blood samples
The device was initially used by medical practitioners to analyze patient blood samples, which was the initial spark that created the field of hematology. The hemacytometer has gone through a series of major development in the 1800s and early 1900s.

Why is a Haemocytometer used?
The hemocytometer (or haemocytometer or counting chamber) is a specimen slide which is used to determine the concentration of cells in a liquid sample. It is frequently used to determine the concentration of blood cells (hence the name “hemo-“) but also the concentration of sperm cells in a sample.
How does the Petroff-Hausser counting chamber work?
Petroff-Hausser counting chambers can be used as a direct method to determine the number of bacterial cells in a culture or liquid medium. In this procedure, the number of cells in a given volume of culture liquid is counted directly in 10-20 microscope fields.
How are cells counted in a hemacytometer chamber?
It is important to distribute the counting areas in a non-biased manner since cells can be more concentrated on one side of the chamber. If you count over only 5 of the 25 large squares, then multiply that value by 5 to obtain the number of cells per central counting area.

How to calculate sperm concentration in a hemacytometer?
Calculating Concentration 1 The mean number of sperm per chamber is thus 130 x 5 or 650 cells per counting area… 2 Multiply the 650 cells per counting area by 10,000 to obtain the number of cells per ml of diluted sample… 3 Multiply 6,500,000 cells per ml of diluted sample by 100…
