A melting point meter is a laboratory instrument used to determine the melting point of a substance, providing valuable information about its purity and identity. This device typically consists of a heating block, a sample chamber, and an optical system. A powdered or crystalline sample is loaded into the sample chamber, and the heating block gradually increases the temperature. As the substance heats up, it transitions from a solid to a liquid state, and this transformation is detected by the optical system. The meter provides a precise measurement of the substance's melting point, which aids in quality control, identification, and research across various industries, including pharmaceuticals, chemistry and material science.
