          Counting-Chambers from Hecht Assistent

          The counting chambers are used for cell counting under the microscope. They are used, for example, when counting leukocytes or erythrocytes. The counting chambers are divided into group squares to simplify counting. The counting chamber consists of a thick base plate and a thin, polished glass pane called a coverslip.

          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:
