Sample sizes are small, being just enough powdered material to fill a small capillary tube, and the output reading is accurate to within 0.3 – 0.5C with good reproducibility. Digital control means that the sample is heated, the melting point recorded, and the apparatus cooled ready for the next sample is just a few minutes, without operator intervention. The modern melting point meter is faster and more accurate, providing reproducible results which do not rely on the skill of the individual operator and which can be printed for a permanent record. Why then, should one invest in an automated melting point meter? While it is possible to manually heat a sample and observe it, perhaps through a microscope, to determine melting point, this is a cumbersome and unreliable approach. HD recording function, easy to observe and look back. It is a necessary instrument for the production of drugs, spices, dyes and other organic crystal substances.Corresponding enterprises (pharmaceutical related enterprises, chemical enterprises) 1. It is also a technique which it is possible to complete, without specialist equipment. 1.Micro Melting Point Meter plays an important role in chemical industry and medical research. The determination of melting point is a fundamental technique in sample analysis, yielding essential information on material composition and purity. The advantages of automatic and semi-automatic measurement This effect is used to identify the degree of impurity of the substance. As a result, most substances that are examined with a melting point meter have a melting interval. Even impurities during the manufacture of chemicals cause this melting point to expand to a melting interval. Due to impurities, such as impurities or dopants, most substances have a melting interval (beginning of the melt to completion of the melt) of a few degrees Celsius. A well-defined melting point is only given for 100 percent pure substances. The purity of substances can also be qualitatively measured via melting point. 7 min Heating rate when measuring: 1 ☌/min Magnifying glass: 20 dpt / 5 x Lighting: 2 x LED Dimensions housing (WxDxH): 320 x 6.5 x 260 mm Dimension table stand (WxH): 85 x 55 mm Dimensions capillaries: 1.45 mm x 80 mm Protection class: IP 20 Weight: 4.The determination of the melting point is of great importance in the identity test, since many substances can be determined by their melting point.
