UseofaHemacytometer
A hemacytometer (also spelled hemocytometer) is an etched glass chamber with raised sides that will hold a quartz coverslip exactly 0.1 mm above the chamber floor. The counting chamber is etched in a total surface area of 9 mm2 .Calculation of concentration is based on the volume underneath the cover slip. One large square (see W in Figure 2) has a volume of 0.0001 ml (length x width x height; i.e., ......阅读全文
