Preparing a Wet Mount Slides

Prior to you start building your slides, make sure you have whatever you will need, including slides, cover slips, droppers or pipets and any chemicals or stains you plan to use.

Standard slides can be either plastic or glass and are 1 x 3 inches (25 x 75 mm) in size and 1 to 1.2 mm thick.

Wet slides will use a cover slip or cover glass, a very thin square piece of glass (or plastic) that is positioned over the sample drop. Without the cover in place, surface area stress would trigger the bead to bunch up in a dome.

    We used following steps in our university in Kentucky to prepare wet mount slides:

    – Using a pipette, place a drop of water on the specimen.
    – Then place on edge of the cover slip over the sample and thoroughly lower the cover slip into place utilizing a toothpick or equivalent.

    This approach will assist prevent air bubbles from being caught under the cover slip.
