An evaporating dish is a piece of laboratory glassware used for the evaporation of solutions and supernatant liquids, [a] and sometimes to their melting point. Evaporating dishes are used to evaporate excess solvents – most commonly water – to produce a concentrated solution or a solid precipitate of the dissolved substance.

2023年11月21日 · An evaporating dish is a heat-resistant dish made from borosilicate glass or porcelain. Typically, evaporating dishes are relatively shallow and wide, without measurement...

2023年9月5日 · An evaporating dish can be used to promote crystallization by slowly evaporating the solvent of a saturated solution. As the solvent evaporates, the concentration of the solute increases until it reaches its maximum saturation point, at which point crystals begin to form.

Evaporating dishes are pieces of heat-tolerant laboratory glassware that are used to hold substances or liquids that are being melted or evaporated. They are typically made of borosilicate glass (as in Pyrex evaporating dishes) or porcelain (also called “china dishes”).

2024年12月3日 · A evaporating dish is a laboratory equipment used in chemistry to evaporate and concentrate a solution or a solid substance. It is a crucial tool in various laboratory settings, including analytical, synthesis, and quality control laboratories.

2019年11月21日 · An evaporating dish is a piece of laboratory glassware used for the evaporation of solutions and supernatant liquids, and sometimes to their melting point. Evaporating dishes are used to evaporate excess solvents – most commonly water – to produce a concentrated solution or a solid precipitate of the dissolved substance.

Evaporating dishes are primarily used for the process of evaporation, where a liquid is heated to allow the solvent to evaporate, leaving behind the solute or residue. Unlike crucibles, evaporating dishes are not designed to withstand extremely high temperatures.

2023年8月9日 · Evaporating dishes are traditionally used to evaporate solvent to concentrate a solution; however they can also be used to hold sand for a sand bath, as a small water bath, or as a...

2022年6月16日 · Evaporating dishes are used to evaporate excess solvents – most commonly water – to produce a concentrated solution or a solid precipitate of the dissolved substance.

Evaporating dishes are staples in laboratories around the world. These dishes are made from ceramic or glass and are used to heat liquids to a point of evaporation, leaving a solid residue. They are available in standard- or shallow form and can have lips, rims, and spouts.
