Manual Polarimeter WXG-4
WXG-4 manual polarimeter, measuring range from -180 to +180 degrees. The instrument is suitable for measuring the optical rotation of optically active substances. Accuracy: 0.05 degrees.
WXG-4 manual polarimeter is equipped with a 589nm sodium lamp. Switch on the power, the polarized light beam immediately radiate to polarizer filter. You can observed distinct visual fields through eyepiece. Put the sample tube into the measuring field chamber, rotate the vernier knob, you will find an equal brightness. Reading and recording the measured value from vernier scale, the testing is completed.
