Rinse slide to be mounted with DISTILLED OR DEIONIZED WATER, touch the edges of slide on a paper towel to remove excess water. Place slides on a flat surface. Turn the vial upside down and open the dropper to remove any air bubbles. Apply 2-3 drops of mounting medium and apply coverslip carefully without getting air bubbles. The specimen is ready for visualization under a microscope. The coverslip may move, so it may be necessary to seal the edges of cover slip with nail polish, any organic medium or our Organo mounting medium.
