Should a cover slip be used with wet mounts?
Wet slides will use a cover slip or cover glass, a very thin square piece of glass (or plastic) that is placed over the sample drop. Without the cover in place, surface tension would cause the droplet to bunch up in a dome.
Why would you put a coverslip on your wet mount slide?
Cover slips are small squares of glass that cover the specimen placed on the microscope slide. They flatten the specimen for better viewing and also decrease the rate of evaporation from the sample, both in wet and dry mounted slides, explains the Newton website.

Do dry mounts require a cover slip?
The two types of microscope slide preparation techniques include dry mount slides and wet mount slides. Dry mount slides require a blank glass microscope slide, a glass cover slip, and a non-moisture based specimen.
Why is cover slip used in wet mount?
This smaller sheet of glass, called a cover slip or cover glass, is usually between 18 and 25 mm on a side. The cover glass serves two purposes: (1) it protects the microscope’s objective lens from contacting the specimen, and (2) it creates an even thickness (in wet mounts) for viewing.
When would you use a wet mount slide?
Most people are familiar with coverslips being placed on slides to protect the sample, but that’s not the only reasons that coverslips are important. They also affect the image quality. Coverslips function by working with your microscope to focus light to a single point and avoiding unnecessary noise in your image.
Why use a coverslip when preparing a wet mount?
