Figure 3. A) The needle is removed quickly from the syringe. B) Five ml of air is aspirated into the syringe, and the needle is placed back on the syringe. C) With the needle bevel facing down, 1 drop of aspirated material is expelled onto each of several glass slides. Slides are labeled and placed on the table before aspiration, ready for use. D) With a second slide, smears are prepared in a manner similar to that for blood smears. Slides are then immediately wet fixed by placing them in an alcohol bottle.
