Counting chamber Thoma, with clamps

Sales Unit

The counting chambers serve to determine the number of particles per volume unit of a liquid. The particles (e.g. leucocytes, erythrocytes, thrombocytes, bacteria, fungus spores, pollen) are visually counted under a microscope. The types of counting chambers differ in counting grids and the depths of the chambers. Orthogonal lines form grids which become visible by magnifying them with a microscope. The grid of a counting chamber is engraved into the surface of its base.
