Haemocytometer, Improved Neubauer PatternFor estimating particles in suspension; this slide is designed for routine counts of red cells and white cells in blood but can also be used for counting bacteria or yeast cells. The cell has two counting grids, separated by a central trough and divided into 400 squares 0.05 x 0.05mm. With the special coverslip in place a volume of 2.5 x 10-4 mm3 overlies each square. This enables numbers of cells per unit volume to be determined. Supplied complete with two special coverslips.
