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.

  • The chemist transferred the solution into an evaporating dish and placed it on a hot plate to evaporate the solvent, leaving behind the desired solute.
  • During the experiment, the student heated the evaporating dish gently to remove excess water from the sample, allowing for accurate measurement of the solid residue.
  • The laboratory technician used an evaporating dish to concentrate a dilute solution by evaporating off the solvent under reduced pressure.
  • In the metallurgy lab, the engineer used an evaporating dish to separate gold particles from the solution by evaporating the mercury.
  • The biologist utilized an evaporating dish to prepare nutrient agar for bacterial culture by evaporating water and solidifying the agar medium.
