Evaporating Dish

Home > Laboratory Glassware > Evaporating Dish

An Evaporating Dish is a kind of laboratory glassware highly useful in the evaporation of solids. It�s a very simple and non-mechanical device that works on the principal of evaporation of water or water content in a liquid. It facilitates the evaporation of excess solvents, most commonly water, to produce a concentrated solution or a solid precipitate of the dissolved substance.

Evaporating dishes are usually made of porcelain or borosilicate glass. However, some used for high temperature work are made of refractory metals normally of platinum due to its non-reactive behaviour and low risk of contamination. The capacity of evaporating dishes is usually small - in the range 3-10 ml. Larger dishes, up to 100 ml, are different in shape, and are more hemispherical.
