Step

Use a flat glass slide to prepare a wet mount. The slide should be clean and free of dust or other fine particles.

Step

Suck up a few drops of your liquid specimen into a medicine dropper.

Step

Pick up a flat glass slide with one hand, grasping it by the outer edges.

Step

Place one drop of the liquid specimen in the medicine dropper on top of the slide. Make sure the drop goes on the center portion of the slide.

Step

Put down the medicine dropper. Do not tilt the slide in your other hand while you are doing this.

Step

Use your free hand to carefully pick up a cover slip (they are extremely fragile). Grasp the cover slip by the outer edges.

Step

Place the cover slip on top of the slide, making sure the edges of the cover slip match up with the edges of the slide. Do not press down on the cover slip.

Continue to grasp the slide/cover slip combination by the outer edges. You should keep the slide as horizontal and steady as possible, and place it on the viewing tray of your microscope.
