Description

For the measurement of angle of rotation of optically active substances in solution i.e. angle through which the plane of polarized light is rotated on passing through specified length of solution of known concentration. Specific rotation may then be determined the circular head is attached near the analyzer and vernier movement on the scales enables the reading of optical rotation accurate up-to the accuracy of 0.1”. soleil’s Bi-Quartz Laurent’s half shade device which makes the instrument accurate and simple for use with white light(day light) or sodium light. The polarimeter tubes made from borosilicate glass with fittings at both ends. The tubes and covers with glass round disc, optically true with rubber washers to make it leak proof. Complete with a set of two polarimeter tubes (100mm and 200mm) in wooden case, nicely polished. P.S. research polarimeter and sugar scale sacharimeters also available.
