Principle Of Hemocytometer For Cell Counting A Zoomed Inset Of A A hemocytometer , also known as a neubauer chamber, is a microscope slide that contains a counting chamber with a grid etched into the glass. it is commonly used to count cells or other microscopic particles in a sample of fluid such as blood, urine, or cerebrospinal fluid. Position the coverslip over the chambers. resuspend the cell mixture and place 10 μl of stained cells into the hemocytometer chamber using a 20 µl pipettor. note: be careful not to move the coverslip. allow capillary action to draw the sample in. place the hemocytometer on the stage of a binocular light microscope. Steps. 1. using a pipette, take 100 µl of trypan blue treated cell suspension and apply to the hemocytometer. if using a glass hemocytometer, very gently fill both chambers underneath the coverslip, allowing the cell suspension to be drawn out by capillary action. if using a disposable hemocytometer, pipette the cell suspension into the well. A 1:1 ratio of trypan blue to cell suspension (equals 2 fold dilution)1. vortex briefly (touch spin if using 1.5 ml microfuge tubes to bring contents down from lid). pipette 10 μl of trypan blue cell suspension into hemocytometer chamber, between chamber notch and glass coverslip (figure 1a, black arrow). count cells in boxes 1 4 (figure 1b.

Count the number of dead and alive cells in 5 of the large squares of the hemocytometer grid, using phase contrast microscope under ~10x power. for standardization, count those in the 4 corner squares and center square. for cells touching an edge, count the ones touching the top and left edges and exclude those touching bottom and right edges.
