Watch Glasses

Watch Glasses are a special type of laboratory equipment, used for conducting chemical experiments. It is a concave piece of glass, which is circular in structure and is an ideal equipment for several processes. Some of the procedures performed using watch glasses are evaporation of a liquid, weighing of solids, covering a beaker and to hold a small quantity of any substance. When used for covering the beaker it does not completely seal off the beaker as the entire mouth is not covered and thus, it prevents dust or any contaminating foreign particles from entering the beaker while allowing the exchange of gases.

A watch glass is constructed in this manner so that it allows an individual the opportunity to closely observe the chemical process, especially during evaporation. The precipitation or crystallization can be observed carefully by placing it on a surface of different colour, making it clearly visible.

Uses and types of watch glasses

Watch Glasses are available in several sizes and are generally measured using the diameter of the circular surface. They are of two types, plastic, and glass; with the latter being the most widely used type as the former might react with corrosive chemicals. For covering beakers, a watch glass with a big diameter is used; however, its diameter need not be equal to that of the beaker. This allows one to alter and control the conditions for saturation of vapour. This equipment, which is often classified under laboratory glassware, is found in every chemical laboratory. It is also used for weighing solids, as it is quite light and can be placed on the scale easily. For obtaining the right weight of the substance, the scale needs to be adjusted to subtract just a small weight. It is also generally used for drying out solids, and can also be used conveniently when volatile solvents are involved. The commonly available sizes of watch glasses through are of diameters 80mm, 100mm, 120mm, and 150mm respectively.

Best quality products through leading brand names
