System Features
Advanced instrument control
High speed, precision and accuracy
The P-2000 offers a response speed as fast as six degrees per second to provide reproducible data for each measurement with a resolution of 0.0001°. A wide dynamic range of up to ±90° enables the system to measure chiral compounds over a broad range of concentrations. The sample chamber is equipped with an integrated temperature, the current temperature constantly updated on the instrument control screen.
Full line of accessories
In support of diverse applications, a full line of accessories including a variety of cylindrical cells: a demountable stainless steel cell, Peltier thermostatted cell holder, and monochromator options, all offered for functional expansions of the P-2000. Quick-connect fittings with flow control valves in the sample compartment provide simple and secure exchange of waterthermostatted cells for temperature control with water baths. A newly developed Peltier cell holder offers accurate temperature control with ±0.1° accuracy.
Reliability and instrument verification
An automated validation program is available for GLP/cGMP laboratories or those regulated by the FDA. The program can be used for automated periodic validation of light source energy, zero repeatability, and rotational accuracy/repeatability. Inspected filters, sample cells with certified optical path length, and NIST-traceable rotation plates are also available.
Ultimate flexibility
With its single optical platform, the P-2000 can be customized to provide the optimum performance for every application. By selecting the most suitable combination of optical elements, the instrument can be used in the ultra-violet, visible and/or NIR regions.
Details
A new generation of polarimeters offering simplicity, reliability and complete validation protocols
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.
Full line of accessories
The P-2000 Digital Polarimeter provides a wide 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).
