A high-accuracy multi-option digital polarimeter for all laboratory applications.
The P-2000 is a configurable high precision polarimeter with many options making it suitable for any application or budgetary requirement. The digital polarimeter may be field upgraded as application requirements change. Options for wavelength filters and source lamps can be used for a wide range of analytical wavelengths from UV-Visible to NIR.
The P-2000 is designed as a customizable polarimeter with options for an array of applications and budgetary requirements, with field upgrade options available to deal with changing application requirements.
To support 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 that use water circulators. The Peltier cell holder offers accurate temperature control with ±0.1° accuracy.
The P-2000 Digital Polarimeter offers a range of choices for the control system, light source, cell, cell holder and wavelengths ranging from the UV-Vis to the NIR. A system optimized for any requirement can be configured for the laboratory, including only those items required for the desired application(s).
Two options for operation are available including Spectra Manager™ Suite innovative cross-platform spectroscopy software for Windows. And the intelligent remote module (iRM) with colour LCD touch screen. These two control and analysis interfaces allow full instrument control and data processing. For regulatory compliance 21 CFR part 11 versions for both Spectra Manager and the iRM are available as options.
For fast measurement, 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. The sample chamber includes temperature measurement with the actual temperature constantly updated and displayed on the control screen.d upgrades for different measurement capabilities as applications and budgets evolve
A validation program is included as standard for GLP/cGMP laboratories or those regulated by the FDA. The program can be used for periodic validation of light source energy, zero repeatability, and rotational accuracy/repeatability. Inspected filters, sample cells with a certified optical path length, and NIST-traceable quartz rotation plates are also available as options.
