These cell counting chambers are moulded from a single piece of thermal and shock-resistant glass.

• 2-cell
• Optically polished platform

An H-shaped moat forms either one or two counting areas, or plateaus. Each plateau features an etched grid or ruling. Contact of the flat, polished cover glass surfaces with the cover glass supports produces an exact volume of fluid over the counting area.

The ruled surface is 0,1 mm below the cover glass, limiting the Volume of 1 Square mm of blood or fluid over a square mm at 0,1 cu.mm.
