Melting-Point Apparatus
While the outward designs of apparatuses can vary greatly, most A melting-point apparatus uses a sample loaded into a sealed capillary (melting-point capillary), which is then placed in the apparatus. The sample is then heated, either by a heating block or an oil bath, and as the temperature increases, the sample is observed to determine when the phase change from solid to liquid occurs. The operator of the apparatus records the temperature range starting with the initial phase-change temperature and ending with the completed phase-change temperature. The temperature range that is determined can then be averaged to gain the melting point of the sample being examined.
A melting-point apparatus usually has a control panel that allows the starting and final temperatures, as well as the temperature gradient (in units per minute), to be programmed. Some machines have several channels, which permit more than one sample to be tested at a time. The control panel might have buttons that allow the start and end of the melting point range to be recorded.
Characteristics
Melting-Point Apparatus is mainly used for measuring the melting point of drugs, dyes, fragrances and other organic compounds crystals.
With LCD screen, the image of whole process of melting the material can be observed, while the instrument provides the melting parameters of the
material. The instrument applies a high-resolution camera or photo-detection system to automatically/manually detect the melting point, software
and hardware. It’s capable of monitoring the entire process of melting material, and while the image is being played back, the whole process of
melting can be observed, and test data can be generated. The instrument is equipped with windows 7 operating system.
