The melting point of a substance is the temperature at which the substance changes from a solid state to a liquid state. In the field of organic chemistry, melting point determination is a basic means to identify the nature of substances, and it is also one of the important methods for purity determination. Therefore, the melting point tester has an important position in the chemical industry, medical experiments, and drug research, and is an essential instrument for the production of drugs, spices, fuels and other organic crystalline substances.
