PASCO’s new Polarimeter has both 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.
Polarimeters pass plane polarized light through a sample, which contains a chiral compound, through an analyzer and a detector. The degree of optical rotation of the plane polarized light is based on the concentration of sample present.
Determine the concentration of a sugar solution based on the optical rotation of plane polarized light.
Explore the simple sugar families and determine which of each students obtain as unknowns
