NADE WRR laboratory digital display Visual melting point instrument/apparatus 40-280C

According to definition of physical chemistry, the melting point of a substance means the temperature at which the substance changes from solid state to liquid state. In the fields 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 methods of measuring purity. So the melting point meter occupies an important place in chemical industry and medicine researches. Also, the melting point meter is a kind of necessary instrument in the production of medicines, perfumes,dyestuff and other organic crystal substances.

The WRR melting point meter is designed according to the rules of pharmaceutical law. It uses the technology of temperature program-control, digital display of initial and final melting points. The temperature system uses the linearly corrected platinum resistor as the detecting element. Additionally it uses the electronic circuits to realize the speedy setting of “start temperatures” and four steps of linear heating rate for being selected. The instrument uses the capillary as the sample tube, whose size correspond to the pharmaceutical law. The user observes the melting process of the sample in the capillary through a magnifier clearly.
