Evaporation Dish
Evaporation Dish is a shallow laboratory container typically made from chemically resistant materials such as porcelain, borosilicate glass, or metal. It is designed to hold liquids for evaporation processes where solvents are removed by heating, leaving behind solid residues or concentrated solutions. The dish provides a wide surface area to facilitate rapid evaporation and is widely used in chemical, pharmaceutical, and educational laboratories. Its durable construction allows it to withstand thermal stress and chemical exposure during repetitive heating and cooling cycles.
