蒸发皿, 蒸发盘
a shallow, flat-bottomed vessel typically made of glass or porcelain, used in laboratory settings for evaporating liquids to concentrate solutions or to precipitate dissolved substances
An evaporating dish is a shallow, ceramic or glass container used to heat liquids and cause them to evaporate, leaving behind solid substances. It is typically used in laboratories for processes like concentrating solutions or removing water from a substance. The dish has a wide surface area, which helps the liquid evaporate more quickly when heated. Evaporating dishes are commonly used in chemistry and other scientific fields to separate mixtures or prepare substances for further study. The material of the dish can withstand high temperatures, making it suitable for heating.
