An evaporating dish or evaporating basin (sometimes referred to as watch glass) is a laboratory item used for the evaporation of solutions and supernatant liquids, and sometimes to their melting point.
Contents
General
Evaporating dishes have the appearance of a thin concave dish with a beak, though some models may have flat bottom. The most common type is made of glazed fired porcelain, though all-glass versions exist. Plastic evaporating dishes are rarely encountered or used, as repeated heating will deform or wear them.
Availability
Evaporating dishes can be bought from lab suppliers or online.
Alternatively, you can use glazed porcelain dishes, though you may not reuse them for food after being exposed to lab reagents or contaminated suspensions/solutions.
Projects
- Evaporate solutions
- Recrystallize compounds
