I、Applications and Applicable Ranges
Type PLG—4 disk polarimeter can be used in the chemical industry, hospitals, colleges and universities and scientific research in situations, for measuring the organic substances with optical rotation. With the aid of the disk polarimeter, the specific gravity, purity, concentration, and content of thousands of active materials, such as sugar solution, turpentine oil and camphor, can be measured. For example: In the food industry: The disk polarimeter can be used to inspect the sugar content and to measure the asylum content of the food flavorings. In the clinic and hospital: The disk polarimeter can be used to measure the sugar content and protein in urine. In the sugar refinery: The disk polarimeter can be used to inspect the concentration of the sugar solution in industrial process. In the medicines and perfumery industry: The disk polarimeter can be used to measure the optical rotation of the medicines and perfumery oil. In colleges and universities: The disk Polarimeter can be used in teaching experiments.
