Description

An evaporating dish is a type of laboratory glassware used for evaporating liquids. It is a shallow, circular dish with a flat bottom and sloping sides. The dish is typically made of porcelain, glass, or other heat-resistant materials, and is used to contain and evaporate liquids as part of a chemical reaction or other laboratory process.

An evaporating dish is used when a liquid needs to be reduced in volume or when a solid needs to be recovered from a solution. The liquid is placed in the dish and heated, causing the solvent to evaporate and leaving behind the solid residue. The sloping sides of the dish help to concentrate the liquid and prevent it from spilling during the evaporation process.

Evaporating dishes are widely used in chemistry, biology, and other scientific disciplines. They are typically used in combination with a heat source, such as a Bunsen burner, and are carefully watched to ensure that the liquid is being evaporated evenly and that the solid residue is not being burned or destroyed.

Evaporating dishes are available in a variety of sizes, materials, and shapes, and can be purchased from laboratory supply companies. They are typically sold in bulk quantities and can be easily replaced if they become damaged or worn. The dish should be cleaned after each use to prevent contamination and to ensure that it is ready for the next experiment.
