Product Code: SE-217A

Polarimeter is a reliable instrument for accurate measurement of Optical Rotations, for study of Polarisation effects and for quick and easy discrimination between right-handed sugars such as Dextrose and left handed sugar such as laevulose. The instruments find use in industries as well as in Colleges and Universities. The Polarimeter essentially consists of a pair of polarisers arrange in a straight line, one of which (analyzer) can be rotated with respect to the other (polariser) and the rotation measured on a divided circle. The circular scales are finely marked on a 10cm diameter circle both in angular measure and in International Sugar Scale. The smallest division on angular scale is 1° ISS. The Sugar Scale is calibrated between -30° (for Laboratory substances) and +130° ISS. The Scale is properly illuminated to facilitate reading.

  • A polarimeter is a scientific instrument used to measure the angle of rotation caused by passing polarized light through an optically active substance
  • Some chemical substances are optically active, and polarized (uni-directional) light will rotate either to the left (counter-clockwise) or right (clockwise) when passed through these substances.
  • The amount by which the light is rotated is known as the angle of rotation. The angle of rotation is basically known as observed angle. Many chemical substance changes their properties when polarized light is passed through it. Polarimeter is used widely and extensively in the Food & Beverage industries.
  • Pharmaceutical as well as chemical industries finds innumerable applications of Polarimeter.
