1、 Definition and purposeEvaporator vessel is a commonly used glassware in the laboratory, mainly used for heating, evaporating, concentrating, or crystallizing liquids. Its shape is usually a round dish with a large mouth and a small bottom, making it easy to quickly evaporate liquids. Evaporating dishes are widely used in fields such as chemistry, biology, and medicine, and are one of the indispensable tools in experimental processes.2、 Materials and specificationsEvaporation dishes are usually made of high-temperature and corrosion-resistant glass materials to ensure their stability and safety at high temperatures. There are various specifications for evaporating dishes, with common sizes such as large mouth and small mouth, to meet different experimental needs. In addition, according to the specific requirements of the experiment, evaporation vessels with special coatings can also be selected to improve their corrosion resistance.3、 Heating methodThe evaporating dish can be heated in various ways, including electric heating, flame heating, etc. When using electric heating, the evaporating dish is usually placed on an electric heating plate and the heating speed is controlled by adjusting the temperature. Flame heating is suitable for experiments that require rapid heating or high-temperature treatment, but attention should be paid to controlling the size of the flame to avoid burning the evaporating dish.
