High-Speed Polarimeter Series-P8100

Kruess

The digital polarimeters of the P8000 series feature an innovative measuring principle to measure optically active liquids. This patented development reduces the measuring time to one second irrespective of the rotation angle of the sample, which, compared to conventional polarimeters, saves a lot of time. All adjustments on the device are made via an easy to use touchscreen. In addition, an easy to understand help display can be called up at any time. With only very little effort, the user can carry out a simple menu-driven calibration using test quartz.

The T-models of the P8000 series are equipped with thermostat interfaces and the delivery includes an external PT31 thermostat. This allows the connection of temperature-controlled gauge heads to achieve high precision measuring results. The devices are intended for use in FDA regulated sectors due to their GLP compliance, integrated user management and full network support, for simple connection to the laboratory environment and an LIMS.

21 CFR Part 11 software is also available for the device. All internal data (measurement values, parameters and methods) are organised in an SQL database. This can be accessed externally using SQL queries through a fixed interface (e.g. LIMS). A self-explanatory touch screen with clear menu navigation and data output and USB/RS-232 interfaces fulfil all demands.
