Cell Counting Microscope

The charged counting chamber is then placed on the microscope stage and the counting grid is brought into focus at low power.

Cell counting microscope.

Sometimes you will need to dilute a cell suspension to get the cell density low enough for counting. 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. The hemocytometer has two gridded chambers in its middle which are covered with a special glass slide when counting.

In that case you will need to multiply your final. If using a glass hemocytometer very gently fill both chambers underneath the coverslip allowing the cell suspension to be drawn out by capillary action. 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. Again multiply by 1000 to determine cell count per ml 250 000. A hemocytometer consists of a thick glass microscope slide with a grid of perpendicular lines etched in the middle.
