Digital Polarimeters

JASCO, a leading manufacturer of polarimeters since 1967, is proud to introduce the P-2000 multi-option polarimeter. The P-2000 is designed as a customizable polarimeter with various options for a range of applications and budgetary requirements. The instrument system can also be field upgraded as the application requirements change.

System Features

Advanced instrument control

Two graphical user interfaces are available including a intelligent remote module (iRM) with a color LCD
touch screen and Spectra Manager 2.5 software, the latest version of JASCO’s innovative cross-platform spectroscopy software. Both of these control and analysis interfaces allow full-system control and advanced data processing. 21 CFR part 11 compliant versions for both interfaces can be ordered as an option.

High Speed, Precision and Accuracy

For fast measurement, the P-2000 has a response speed of up to 6° per second, with an outstanding 4-digit resolution of 0.0001°. The wide dynamic range up to ±90° enables measurement over a very broad range of concentrations.
The sample chamber includes temperature measurement 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.

Light Sources

Up to two light sources can be installed simultaneously inside the instrument with automatic light source exchange and recognition.

The light source can be easily updated in the field.

Wavelength Selection

A comprehensive range of narrow band interference filters covers the entire spectral range with automatic recognition (and an optional filter wheel for completely automated exchange)

The optional wavelength extension kit extends the operating range to include the UV-Visible (253 nm) to NIR (880 nm)


Simplicity, Reliability and Complete Validation Protocols 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 length can be used and NIST-traceable calibration standards are also available.
Polarimeters with both the iRM and Spectra Manager™ include a standard validation program for GLP/cGMP laboratories or those regulated by the FDA.
The validation program can be used to keep track of periodic checking of light source energy, zero repeatability, and rotational accuracy/repeatability to ensure measurements remain in compliance.
Certified filters, sample cells with a certified optical path length, and NIST-traceable quartz rotation plates are available for laboratories that demand the highest quality results.
