Why is specimen placed in water?

Why is specimen placed in water?

In a wet mount, the specimen is placed in a drop of water or other liquid held between the slide and the cover slip by surface tension. This method is commonly used, for example, to view microscopic organisms that grow in pond water or other liquid media, especially when studying their movement and behavior.

What are some advantages of a wet mount specimen?

Wet-mount Slides A wet-mount slide is when the sample is placed on the slide with a drop of water and covered with a coverslip, which holds it in place through surface tension. Advantages – This type of slide preparation allows you to view microscopic living things without them drying out.

What is the purpose of wet mount and hanging drop preparation?

The hanging drop and wet mount techniques allow for observation of living organisms. The wet mount tend to dry out quickly under the heat of the microscope light; it is simpler to perform than the wet mount, but it is useful for short-term observation only.

Why is it necessary to wash the specimens immediately after etching?

After etching, the specimen should be thoroughly washed in water or alcohol and then dried using a hot air blower. The specimen should be carefully stored and cared for in a desiccator, to prevent oxidation and scratching.
