The slide is called a haemocytometer since it was originally designed and used for performing blood cell counts (remember the prefix “haem” means blood). In the lab, a haemocytometer can be used to count a whole variety of cell types, for example in microbiology or tissue culture.

You might want to culture a known concentration of bacteria on an agar plate, or seed a tissue culture dish with a known concentration of cells, and haemoxytometry would be a quick way for you to calculate your cell density.

There are alternative means of determining cell density such as using a spectrophotometer. However this technique does not provide an assessment of cell viability, nor can it distinguish cell types.
