Visual polariMeter

A visual polarimeter determines the optical activity of a substance by measuring the rotation angle of the polarization plane after polarized light passes through the sample. It is used to measure the concentration of sugar solutions, the purity of pharmaceuticals, and the optical activity of chemical raw materials. During operation, the angle of optical rotation is determined by observing when the brightness of the half-shadow field of view becomes uniform.
Selection
When selecting, consider whether the measurement range covers the optical rotation of the sample and whether the precision matches the detection requirements. Check the stability of the sodium lamp light source and the light transmittance of the quartz sample tube. Ensure that the temperature control function is suitable for the experimental environment and that the operation interface is clear for easy reading.
