Manual, Semi-Automatic & High-Speed Fully Automatic Polarimeters

Yatherm Scientific manufactures and supplies customized and standard exclusive line of Manual, Semi-Automatic & High-Speed Automatic Polarimeter, This instrument is designed for measuring the optical rotation of substances. Through measuring the optical rotation, the concentration, content, and purity of the substance can be determined. The instrument is widely used in sugar refining, pharmaceuticals, petroleum, food, chemical and a lot of industrial sectors and related institutions of colleges and research institutes.

Manual Polarimeter


It is Easy-to-use Manual Polarimeter, the measuring range is from -180 to +180 degrees. Yatherm Scientific instrument is suitable for measuring the optical rotation of optically active substances with Accuracy: 0.05 degrees.


The instrument is equipped with a 589nm sodium lamp. Switch on the power, the polarized light beam immediately radiates to a polarizer filter. You can observe distinct visual fields through the eyepiece. Put the sample tube into the measuring field chamber, rotate the vernier knob and find an equal brightness. Reading and recording the measured value from scale disc, testing is completed.
