Abstract
Counting compartment having an inlet and an outlet, and including a bottom plate and a top plate which are held at a distance from each other by material particles which have the same size and are situated at a distance from one another. The particles are surrounded by and embedded in a solid connecting layer formed by an adhesive. The connecting layer extends all around and up to the free end of the outlet of the counting compartment. A fluent mixture of an adhesive mixed with electrostatically charged particles is used to form the counting compartment, the largest size of the material particles determining the depth of the counting compartment. The counting compartment is particularly suitable for counting cells in biological materials such as sperm and blood samples.
