Manual Disc Polarimeter - Visual Polarimeter with Sodium Lamp - ±180° Range - 0.05° Vernier

The Master Science Manual Disc Polarimeter is a classic visual instrument for measuring the optical activity of sugars, pharmaceuticals and organic compounds. The user turns the analyser by hand until the fields in the eyepiece match, then reads the rotation angle from the disc.

The scale covers ±180° with 1° main divisions and a vernier that reads to 0.05° through a 4× magnifier. A sodium lamp gives the 589 nm line. Light and simple, it is well suited to teaching and basic research where students need to see how optical rotation is measured.
