Automatic Polarimeter

Brand : Rudolph Research Analytical
Wavelength Range : 365nm, 405nm, 436nm, 546nm, 589nm, 633nm

  • To measure the angle of rotation caused by passing polarized
    light throughan 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


For mixtures of chiral organic molecules in pure or diluted form, polarimetry provides a rapid, reliable, quality check that eliminates conventional analysis like liquid chromatography which can take an hour to do what the polarimeter accomplishes in minutes. Chemists use polarimetry to test the effectiveness of catalysts and asymmetric synthetic processes.
