WebJul 9, 2016 · A hemocytometer is a thick microscope slide scored with a grid. To use a hemocytometer cells are counted within the squares of the grid and converted to cells/mL using the equation below: # of cells counted / # of squares used to count. (I count the four large corner squares) x dilution factor x 10,000. = cells/ mL. WebThis option will reset the home page of this site.
