JASCO｜Digital Polarimeter

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 (589nm) lamp used for regulatory compliance.
Model : P-2000

Feature :

  • Advanced Instrument Control: Two options for operation are available including Spectra Manager™ Suite for Windows. Or the intelligent remote module (iRM) with color LCD touch screen.
  • High Speed, Precision and Accuracy: The P-2000 has a response speed of up to 6° per second, with a resolution of 0.0001°. The wide dynamic range from 0.001° to ±90° enables measurement over a very broad range of concentrations.
  • On-Time temperature monitor and measurement: The sample chamber includes temperature measurement with the actual temperature constantly updated and displayed on the control screen.
  • Accessories:
  • Sample Chamber Including Quick-connect fittings with flow control valves are used for simple exchange of water jacketed cells(optional) for use with water circulators(optional).
  • Peltier Cell Holder is an optional for more accurate temperature control solution.
  • Optional Sippers accessories built-in ultra micro-pump for automated sampling of small volume samples offers quick and easy measurements of multiple samples.
  • For regulatory compliance a 21 CFR part 11 versions for Spectra Manager PC control is available including Auto Back-up function.
