WebSep 2, 2002 · Hemacytometers were developed for counting blood cells, but can also be used to count spermatozoa. A hemacytometer has two chambers and each chamber has a microscopic grid etched on the glass surface. The chambers are overlaid with a glass coverslip that rests on pillars exactly 0.1 mm above the chamber floor. WebDisposable Hemocytometer The two chambers are called ‘A’ and ‘B’. They are covered with a ‘coverslip’, (you can see a faint outline of it!) thereby allowing two ‘openings’ for each chamber to be formed (1/2 moon shaped at either end of the chamber). These openings are shown in form of two white arrows pointing in each direction (see the image on left). pacific medical group portland oregon
