The Hausser Dark-Line etched hemacytometer is of one piece construction, ensuring long term durability and accuracy.

An H-shaped moat forms two counting areas, or plateaus. Each plateau features enhanced Neubauer rulings.

A "V" slash at the loading side of each plateau facilitates charing and reduces the possibility of overflow into the moat.

The ruled surface is 0.1mm below the cover glass, limiting the volume of blood or fluid over a square mm at 0.1 cubic mm and over each of 400 squares (within the central square mm) to 0.00025 cubic mm.

Contact of the flat, polished cover glass surface with cover glass supports produces an exact volume of fluid over the counting area.
