The Brightline Counting Chamber is made from one piece of high quality glass, milled and polished within strict tolerances, ensuring durability and reliability. The central H-shaped moat forms two counting areas. Each of these areas features Improved Neubauer rulings.
The counting areas are metallized, as opposed to consisting of polished glass, like in a standard chamber. This metallization results in a strong contrast between the lines and the rest of the counting area surface.

The ruled area is 0.1mm below the cover glass, with a tolerance of ±0.02mm. This limits the volume of blood or fluid over a square millimeter to 0.1mm³ and over each of the 400 small squares within the central square to 0.00025mm³. Contact of the cover glass with the supporting areas on the sides of the moat produces an exact volume of fluid over the counting area, and the chamber can be loaded from the side via capillary action, which is ensured by the difference in surface tension characteristics between the metallic surface on the chamber and the cover glass.
All of our chambers go through rigorous quality control at every step of the production process, ensuring that our customers receive a product of the highest quality.
