Product Description
A melting point apparatus is a precision instrument used to determine the melting point of a substance. By precisely controlling the temperature and observing the phase transition of the substance from solid to liquid, the melting point range can be determined.
• To be used to measure the melting point of medicines, dye-stuffs and perfumes and other organic crystal substances to determine their purity.
• Visually detect the initial and final melting points of the sample.
• Measuring three samples at the same time and calculate the average value automatically.
• Use silicone oil or water as heating-conducting medium.
Applications
• Pharmaceutical Industry: To inspect the purity of samples.
•Chemical Industry: To assist in identifying unknown compounds and determining the thermal stability of substances through melting point determination. （*Model WRR-Y Visual Melting-point Apparatus can measure the purity of active pharmaceutical ingredients and finished pharmaceutical products.）
• Food and Cosmetics Industry: To determine whether certain ingredients in food additives or cosmetics meet the standards.
