A semi - circular dish with a mouth, a shallow wall, and a mouth. Sub flat, round bottom two. Open, shallow walls, mainly designed for the evaporation of the solvent. Can increase the liquid surface, to speed up the evaporation rate. With a mouth, mainly to facilitate the dumping of the dish. With hard or extra hard glass production, can be directly heated.
Flat bottomed, stable placement. But the disadvantage is that the heating surface is small, left in the corner of the steam dry matter is not easy to scrape off, wash inconvenience. The circular bottom, the heating surface is big, can accelerate the evaporation speed, the steam dry matter is convenient to scrape off, the washing is also more convenient, the disadvantage is that the position is not smooth. Suitable for the laboratory evaporation of solution, the solvent removal agent in solution, collected by solid. A flat bottomed pan can be used as a substitute for a crystal dish. Large size evaporating dish used for industrial and small batch production tools, or oil bath, water bath with.
