Polarimeter with a measurement range of ±90°, ±259°Z; measurement period approx.1 Second

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.

MINIMUM SAMPLE VOLUME

A volume of just 1.3 ml is sufficient for precise measurement with our 100 mm long cuvette. Filling is done conveniently with a syringe – either directly in the temperature-controlled polarimeter or outside on the laboratory bench. The user-friendly design with a flat base enables safe, easy handling.

AUTOMATIC CUVETTE RECOGNITION

For an intuitive measurement and calibration process, the polarimeter automatically recognizes the cuvette equipped with an RFID tag and records all relevant cuvette data such as:

• Length
• Material
• Temperature control parameters

For maximum process reliability, error-free documentation and automated measurement and calibration processes.

INSIGHTS INTO YOUR SAMPLES DURING FILLING

The rectangular shape of our glass cuvettes allows visual control of the sample filling over the entire length of the cuvette. As with an aquarium, the sample can be inspected from all sides – air bubbles, particles or streaks are immediately visible. This makes it very easy to detect and reliably avoid measurement errors with the naked eye.

AUTOMATIC DOCUMENTATION OF SAMPLE FILLING

With the Sample Cell Check, the filling process itself becomes part of quality assurance. The cuvette can remain in the polarimeter during filling. An integrated camera transmits the filling process directly to the display – conveniently, precisely and without interrupting temperature control. The automatic sample cell check function reliably checks and documents the entire filling process. Especially with automated sample supply (e.g. with autosamplers), the recorded and stored images can be used for documentation or error analysis. This allows you to rule out potential sources of error in advance – for reproducible and reliable measurement results.
