Here are the main features of the haemocytometer. It is a thick microscope slide containing a “H” shaped overflow trough. Either side of the horizontal trough are two polished areas where the counting grids are located. Sometimes the slide has a “V” shaped groove for pipetting in the cell mixture. Turned on its side you can clearly see the trough with a cover slip over the top. The depth between the cover slip and grid is 0.1 mm and you will need to remember this for your final calculations of cell density.

Looking under the microscope at the polished areas you will see a grid etched on to the glass; these are called the Neubauer rulings which is the standard grid design for cell counting chambers and allows you to count small and large sized cells.
