Wireless Polarimeter
PS-3237 / #1625537

Measures the optical rotation of chiral compounds and features Bluetooth connectivity.

PASCO's Wireless Polarimeter passes plane polarized light through a vertical sample, which contains a chiral compound, followed by an analyzer and detector. The optical rotation is determined by finding the angle between the starting position and the location where the optimum light level transmits through the cross polarizer.  Students can use the rotation data to calculate the concentration of a chiral sample, while the specific rotation (amount turned per g/ml dissolved) is an intrinsic property that can be used to differentiate molecules or determine racemic mixtures.
