Polarimeters

Polarimeters are used to measure the rotation of polarized light as it passes through a sample of an optically active substance. These instruments are oftenly used in industries such as pharma, cosmetics, sugar refining, drug manufacturing, as well as the food and beverage, to determine the concentration of substances and perform purity control. ATAGO offers a number of polarimeter models for a broad range of applications.
