Use them to cover beakers to reduce evaporation or prevent stuff falling into it. They can also be used as a reaction surface (glass) since they are slightly concave.
Which piece of laboratory apart it would most likely be used to evaporated E1 millimeters sample of a solution to drynes
A watch glass is commonly used in a laboratory to cover beakers or evaporating dishes to prevent contamination, evaporation, or splashing during experiments. It can also be used as a weighing dish for small amounts of solid reagents or as a surface for gently heating substances over a Bunsen burner.
A glass plate in the laboratory is a flat, smooth piece of glass used for various applications such as microscopy, culturing cells, mixing substances, or as a base for other experimental setups. It provides a stable, clear surface for working with samples or conducting experiments. Glass plates can come in different sizes and thicknesses to suit different laboratory needs.
"Wash glass" refers to a glassware used in laboratories for washing and decanting procedures. It typically has a conical shape with a short stem and a wide base to provide stability. Wash glasses are commonly used in chemistry experiments and other scientific applications.
Another name for beakers is "laboratory glassware" or "glass beakers."
it is used to collect evaporated air/gas in the liquid you have just heated
because glass is transparent
The watch glass may contain small amounts of solid or liquid samples.
because glass is transparent
A watch glass is sometimes used to measure small amounts of solids and evaporate miscellaneous liquids/ chemicals in a laboratory.

A triangular file is often used to stir chemicals, as well as to scratch glass tubing before breaking it.

basic purpose and function of an independent laboratory
The function of a graduated cylinder in the laboratory is to measure volumes.
what are some picture laboratory apparatus and their function
A watchglass can be used as a beaker cover, but you can also place small amounts of chemicals on it and then heat it (for example, to evaporate some water from a wet chemical).From Wikipedia:A watch glass is a circular, slightly concave piece of glass used in chemistry as a surface to evaporate a liquid, or as a cover for a beaker. The latter use is generally applied to prevent dust or other particles entering the beaker; the watch glass does not completely seal the beaker, and so gas exchanges still occur. When used as an evaporation surface, a watch glass allows closer observation of precipitates or crystallisation, and can be placed on a surface of contrasting colour to improve the visibility overall. Watch glasses are so named because they are identical to the glass used for the front of old-fashioned pocket watches. In reference to this, large watch glasses are occasionally known as clock glasses.See the Related Questions and Web Links to the left for a picture of watch glass and more information about other laboratory apparatus.
