PASCO’s Polarimeter has both low energy Bluetooth® and USB connectivity, so it works on your iPad®, Chromebook™, tablets, and computers. It is ideal for introductory Organic and Biochemistry experiments with chiral compounds. Plane polarized light passes through a vertical sample of solution then through an analyzer and a detector. Finding the angle from start to where the optimum light is transmitted through the cross polarizer gives the optical rotation. The rotation can be used to calculate concentration and the amount turned per g/ml dissolved (specific rotation) is an intrinsic property that can be used to differentiate molecules or determine racemic mixtures.
