Laboratory tripod is a commonly used support tool in chemical experiments, consisting of three metal supports, usually made of iron or stainless steel, with high temperature resistance and corrosion resistance. The top of the tripod is designed with a platform for placing experimental instruments such as evaporating dishes, crucibles, or beakers, while the bottom has three adjustable legs to ensure the stability of the device. In teaching, tripods are commonly used for experimental operations such as heating, evaporation, or concentration of solutions, helping students understand the heating reactions and physical changes of substances. They are essential basic equipment in chemical experimental teaching.
