Cell Counting Microscope

When using a light microscope to examine living cells you may want to calculate the cell density.

The charged counting chamber is then placed on the microscope stage and the counting grid is brought into focus at low power. In that case you will need to multiply your final. A hemocytometer consists of a thick glass microscope slide with a grid of perpendicular lines etched in the middle. Hemocytometers and sedgewick rafter counting chambers are two types of counting chambers.

A variety of cell counting methods exist for exactly this purpose including the hemocytometer. Using a pipette take 100 µl of trypan blue treated cell suspension and apply to the hemocytometer. Cell counting is rather straightforward and requires a counting chamber called a hemocytometer a device invented by the 19 th century french anatomist louis charles malassez to perform blood cell counts. Cells are the basic units of life and contain cytoplasm dna ribosomes and a cell membrane.

A counting chamber is a microscope slide that is especially designed to enable cell counting. Sometimes you will need to dilute a cell suspension to get the cell density low enough for counting. A drop of cell culture is placed in the space between the chamber and the glass cover.
