Easy-to-use manual polarimeter, measurement range from -180° to +180°. iDP10 polarimeter is suitable for measuring the optical rotation of optically active substances. Accuracy: 0.05°.
This instrument is installed with a 589nm sodium lamp. Switch on the power, the polarized light radiates to the polarizer filter. The user is able to observe the distinct visual fields through eyepiece. Place the test tube into the measuring chamber and rotate the vernier knob until the visual fields appear the equal brightness. Recording the vernier scale. Measurement is done.
