Polarimeter - Rudolph Autopol III

The Rudolph Autopol III Polarimeter measures the optical activity of a compound at 589 nm (sodium D line).  A solution of known concentration and volume is prepared and inserted into a polarimetry cell (10 cm or 1 cm).  


When polarized light is passed through a solution containing an optically active compound, the polarized light will rotate clockwise or counter-clockwise.  The specific rotation is calculated based on the observed optical rotation by taking into account the cell length and sample concentration.
