Coulter Counter

Coulter counters provide a readout of RBC parameters including the hematocrit and hemoglobin concentration. The mean cell volume (MCV) is measured in femtoliters. Macrocytes are usually classified as RBCs with MCV >100 fL and microcytes <80 fL In a Coulter counter, a tube with a small aperture on the wall is immersed into a beaker that contains particles suspended in a low concentration electrolyte. Two electrodes, one inside the aperture tube and one outside the aperture tube but inside th A Coulter Counter is an instrument that can count and size the cells in an electrolyte to provide valuable information for researchers. For example, the number of cells of a certain type in a blood sample can provide clues to the type of disease that a patient is suffering

Coulter Counter Coulter counter is commercially available device for determining the size distribution of electrically nonconducting particles suspended in a conducting medium. Two electrodes passing constant current are placed on either side of a small hole or aperture through which the suspension is sucked In a Coulter Counter instrument, a tube with a small aperture on the wall is immersed into a beaker that contains particles suspended in a low-concentration electrolyte. Two electrodes, one inside the aperture tube and one outside the tube but inside the beaker, are placed and a current path is provided by the electrolyte when an electric field is applied (Figure 1) Cell Counters, Sizers and Media Analyzers.
