Abstract
Cells in a suspension are counted in a hemocytometer slice with a chamber of controlled depth and one or more reservoirs along one or more side edges of the chamber. The suspension is fed to a reservoir to first fill the reservoir, and then to overflow into the chamber. The result is an even distribution of the cells in the chamber.
