Lab Watch Glass

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.

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.

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 glassware’s like beakers. Made with high quality borosilicate glass and also easy to clean.

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.

The watch glass in chemistry lab price varies from size to size and their material quality from which they are made.

No, we can not directly heat a watch glass due to its uneven heat distribution while heating and also causing shatter due to thermal stress.

You can clean the lab watch glass using mild detergent and distilled water.
