Counting chamber - The details

Counting chambers are used to determine the concentration of cells. The concentration of cells is calculated by counting the number of cells in a given square and the volume of the respective chamber. The counting chambers are available in four different designs. They differ mainly in the structure of the counting squares:

Classification according to Thoma:

• For platelet and for erythrocyte counting
• Total area: 1 mm²
• 16 group squares with a square area of 0.04 mm
• 400 smallest squares with an area of 0.0025 mm²

Classification according to Thoma new:

• For erythrocyte and leukocyte counting
• Total area of 1.21 mm²
• Smallest squares are 0.0025 mm each

Division according to Neubauer:

• For erythrocyte and leukocyte counting
• 9 large squares with 1mm² area each

Division according to Fuchs-Rosenthal:

• For cell counting in cerebrospinal fluid (CSF)
• Total area: 16 mm²
• 16 large squares of 1 mm² each
