Abstract: The invention relates to a counting chamber for a microscope, adjustable in height. The method measures a cell count at two different chamber heights and deduces the concentration of particles without an exact calibration of the absolute height, as the height difference gives a measurement of the “missing” volume and therefore an estimate of the particle concentration.
