How To Use A Hemocytometer To Count Cells Rs Science Move the hemocytometer to the next set of 16 corner squares and continue to count until all 4 sets of 16 squares are counted. take the picture below as an example, the cell numbers of 4 sets of 16 squares are 3, 5, 6, 4, respectively. therefore, the average cell number of this counting is (3 5 6 4) 4 = 4.5. The hemocytometer is a counting chamber device originally designed and usually used for counting blood cells. the hemocytometer can be purchased from amazon. to use, place the coverslip over the counting surface. introduce the cell suspension (10~20 μl or one drop) from the edge of the coverslip with a fine tip transfer pipette.
How To Use A Hemocytometer To Count Cells Rs Science Using a hemocytometer in four simple steps. 1. dilute your sample with trypan blue. trypan blue is a stain that allows you to distinguish dead cells from living cells. when mixed with your cell sample, any dead cells will be stained blue by the dye, meaning that you can count only those cells that are living and viable. 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. There can be tens of thousands of cells in one milliliter of culture medium. so how are cells counted?the process requires diluting the cell culture, dying. 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.

Place the coverslip on the hemocytometer, on top of the two coverslip supports on the sides of the overfill chambers. mix your sample well and pipette a small amount into both chambers, avoiding to push the fluid too hard; it should go in almost on its own by capillarity. 5. counting the yeast in the central square of the hemocytometer.
