On request, blood cell counters with “Bright Lines” grating are available which facilitate the evaluation of the sample thanks to the luminous lines that contrast well with the dark background.
The depth of the Malassez chamber is 0.2 mm.
The counting grid covers 2 x 2.5 mm².
The rectangles have an area of 0.25 x 0.20 = 0.05 mm².
Each of them is divided into 20 small squares with an area of 0.05mm x 0.05mm = 0.0025mm² each.
This chamber is used for counting cells in the cerebrospinal fluid and for counting roundworms.
