Product Description
NADE WRS-2 laboratory Microprocessor melting point instrument/apparatus Room temp -300C
In according with the definition of physical chemistry, the melting point of substance means the temperature at which the substance changes from solid state to liquid state.In the field of organic chemistry, the measurement of melting point is a basic means of organic chemistry, the measurement of melting point is a basic means of
recognizing the nature of substance, and is also one of the important place in the chemical industry and medicine researches.Also, the melting-point meter is a kind ofnecessary instrument in the production of medicines, perfumes, dyestuff and other organic crystal substances.
