14. a-Hemocytometer counting chamber (Neubauer,s chamber).
b-WBCs counting pipette.
c-Rubber tube with a plastic mouth piece for drawing the fluid into a pipette.
d-Special hemocytometer coverslip
e-Diluting fluid.
f-Microscope.
Apparatus and Reagents

17. The area of each large corner square is 1 mm2, the depth of the chamber 0.1 mm (from chamber
surface to coverslip), the volume of blood in one square is 1 mm (length) × 1 mm (width) × 0.1 mm
(high) = 0.1 mm3 ,volume of four corner squares = 0.1 mm3 × 4 = 0.4 mm3 .
No. of cells in large corner square = N.
