Haemocytometer

Haemocytometer Calculation

This is a simple calculation to observe large microbial cells (e.g. yeast) in a haemocytometer chamber. Here you have to estimate the number of cells that would be present in a given volume of the original culture and you can check your answer

Formula Used:

Hemocytometer Calculations Suppose that 20 cells are counted in the cytometer, area 1 mm2 and depth 0.02 mm. Calculate the total number of cells in the original volume of 5 cm3 of broth.
* Vol of chamber = 1 mm x 1 mm x 0.02 mm = 0.02 mm3
* 1 cm3 = 1000 mm3 ? vol = 2 x 10–5 cm3
* ? concentration = 20/(2 x 10–5) = 106 cells per cm3
* ? number in 5 cm3 = 5 x 106 cells
