The haemocytometer is a thickened glass slide with small chamber of grids cut into the glass and is used to count cells. Each chamber has a fixed volume and is etched into nine large squares (see figure, P to X ), each measuring 1mm×1mm and 0.1mm deep. Each large corner squares (P,R,V and X) contain 16 small squares. With a coverslip in place, each of these small squares represents a volume of 0.1mm3 1.0mm2 area ×0.1mm depth ) or 10-4cm3. The number of cells counted in 4 large corner squares was 400, with the conversion factor as 1000.
