What is the function of a watch glass in laboratory work?

The main function of a watch glass in the lab is to evaporate the liquids slowly, covering the dishes and beakers to prevent them from dust and other contamination and also used for holding the small quantity of solid substances. It is a versatile lab glass that is used in every chemistry lab.

What are the common uses of a watch glass in the laboratory?

Common uses of watch glass in laboratories include evaporation of solvents without heating, also used as a lid to cover surface of beakers, and commonly used in observations of chemical reactions.

Why is a watch glass used in chemistry labs instead of petri dishes?

In chemistry labs, watch glasses are preferred over petri dishes for their shape and heat resistance capacity which are essential for evaporation and covering samples in other glasswares like beakers. Made with high quality borosilicate glass and also easy to clean.

What types of lab watch glasses are available?

You can find lab watch glass in various diameters, such as 50mm, 75mm, 100mm, and more, made from borosilicate or soda-lime glass. Some are plain, while others are ground-edged for better safety and grip. We have various sizes available such as 50mm, 65mm, 75mm, 100mm, 125mm, 150mm.
