The P1000-LED polarimeter is a simple and robust device for basic applications in the lab and for training. It operates according to the half-shade principle and the reading takes place via an eye-piece and vernier scales. The P1000-LED features a high-quality metal stand and a sample chamber for tubes of up to 220 mm length. The life of the LED is estimated to last around 500 times longer than traditional sodium vapour lamps. It is equipped with a swivel-mounted cover, polarizer and analyzer and the delivery includes accessories.

Automatic Polarimeter

The P3000 is a very easy to operate polarimeter for the fully automatic measurement of the optical rotation. The measurement value is automatically shown directly after the sample has been inserted and output in angular degrees. The delivery of the polarimeter includes accessories and PC software for the operation and storage.
