Applications
The Lasany LI-P701 Digital Automatic Polarimeter is widely used in pharmaceutical laboratories, sugar industries, food processing plants, chemical laboratories, academic research institutes, and quality control laboratories for measuring optical rotation, sugar concentration, and purity of optically active compounds.
Working Principle
The polarimeter measures the angle through which plane-polarized light is rotated when it passes through an optically active sample. The measured optical rotation is directly related to the concentration and purity of the substance, making it an essential instrument for quality control and analytical testing.
