Digital Polarimeters

P-2000 Series

High-accuracy multi-option digital polarimeter for all applications.

P-2000 Digital Polarimeters

The P-2000 is a configurable high-precision digital polarimeter with many options for measurement range, sampling accessories, and software applications. The P-2000 digital polarimeter can also be field upgraded as application requirements change. Optional wavelength filters and source lamps cover a wide range of analytical wavelengths from UV-Visible to NIR, in addition to the traditional sodium (589 nm) lamp used for regulatory compliance.

System Features

Simple operation

The Spectra Manager™ Suite has a simple user interface operating and measurement. Where a PC is not required, a second option is the intelligent remote module (iRM) with a color LCD touchscreen.  Spectra Manager CFR is used where regulatory compliance to 21 CFR part 11 is required.

Light sources

For full compliance, a sodium (Na) lamp (589 nm) is the preferred option, but measurement to compliance standards can be made with a tungsten halogen (WI) lamp and a high-quality bandpass filter. The third choice is a mercury (Hg) lamp that can be used with a number of intense emission lines for wavelengths from visible to UV.

High Speed, Precision, and Accuracy

For fast measurement, the P-2000 has a response speed of up to 6° per second, to a resolution of 0.0001°. The wide dynamic range from 0.001° to ±90° enables measurement over a very broad range of concentrations. The sample chamber includes temperature measurements with the actual temperature constantly updated and displayed on the control screen.


For a diverse range of sample types and measurements, the accessories and cells include many different options: a range of cylindrical and demountable stainless steel cells, a Peltier thermostatted cell holder, and monochromator options. Quick-connect fittings with flow control valves are used for simple exchange of water-jacketed cells for use with water circulators.

Validation and Regulatory Compliance

The automated validation program is compliant with the requirements of GLP/cGMP, USP, and FDA. Validation is used for automated periodic testing of light source energy, zero repeatability, and rotational accuracy/repeatability. For guaranteed measurement accuracy, filters and sample cells with certified optical path lengths can be used and NIST-traceable calibration standards are also available.
