Polarimeter P9100-P with Peltier temperature control
The devices from the P9000 series are digital polarimeters that were designed to measure the optical rotation, specific rotation or concentrations of liquid, optically active samples. The measurement is based on the ability of optically active substances to rotate the polarization direction of light. By determining the rotation, the substance and its concentration is determined. With an optical sensor, temperature control, measuring electronics, evaluation electronics and a touch display, the devices contain all the components needed to carry out measurements reliably.
The devices and their firmware meet all requirements for FDA-regulated areas, as well as for the European (EP / Ph. Eur.), American (USP), British (BP) and Japanese (JP) pharmacopoeia.
