1 A Haemocytometer Showing The Four Squares With One Square Enlarged Download scientific diagram | 1: a haemocytometer showing the four squares, with one square enlarged to show cell counting technique. image adapted from simulab corporation (2014). from. The area of the middle (figure 3a) and each corner square (figure 3b–e) is 1 mm x 1 mm = 1 mm 2. the depth of each square is 0.1 mm. hence, the final volume of each square at that depth is 100 nl. 4. calculating cell concentration. you can calculate your cell concentration using the following formula: total cells ml = (total cells counted x.

1 A Haemocytometer Showing The Four Squares With One Square Enlarged Example: if the cell counts for each of the four outer squares were 21, 15, 20, and 17 at a 100 dilution factor then the average cell count would be (21 15 20 17) ÷ 4 = 18.25. therefore, the total concentration of cells in the original suspension would be: 18.25 x 100 x 10^4 = 18,250,000 cells ml. How to count cells with a hemocytometer. 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. Cell concentration can be determined using the following equation: total # cells ml = average viable cell # (step 8) x dilution factor x 104. example: average viable cell # square (step 8) = 35 with 1:10 dilution: total # cells ml = 35 x 10 x 10 4 = 3.5 x 10 6 cells ml. cell viability can be calculated by the following equation:.

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. Cells per ml = the average count per square x the dilution factor x 104 (count 10 squares) example: if the average count per square is 45 cells x 5 x104 = 2,250,000 or 2.25 x 106 cells ml. total cell number = cells per ml x the original volume of fluid from which cell sample was removed.
