Porcelain evaporating dishes evaporate liquid into solid residue or concentrate.
An evaporating dish is a tool used in labs to separate liquids and solids from a solution by allowing the water to evaporate off into the air. The result is either a more concentrated solution or the solid precipitate of the dissolved substance.It looks like a small bowl (made of borosilicate glass or ceramic) with a pour spout. Sometimes they're also called an evaporation dish or evaporating basin. The clear shallow type is called a watch glass, since it resembles a watch face.We sell sizes ranging from a 35 ml capacity to 200 ml. They're made from thermally-stable porcelain that's glazed inside for easy cleaning. Our watch glasses come in 65 mm or 100 mm capacity and are also useful for covering beakers to prevent condensation escape.In a science lab, use porcelain evaporating dishes to heat chemical solutions and drive off the solvent, leaving behind the residual chemical solute. This is usually done by heating the evaporating dish over a burner.
