A.KRÜSS Optronic P8000-DT digital polarimeters with Rinsing and Drying Module
The fastest polarimeters in the world!
The digital polarimeters of the P8000 series feature an innovative measuring principle to measure optically active liquids. Our patented measuring technology works much faster than in conventional polarimeters, as it reduces measuring time to just one second, regardless of the rotation angle of the sample. In addition, it permits continuous measurement, for example for kinetic investigations or in HPLC use. All adjustments on the device are made via an easy to use touchscreen. An easy to understand help display can be called up at any time. With minimum 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. The connection of a temperature-controlled gauge head permits extremely accurate measurement. 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. 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). With KrüssLab software, the device can be controlled by PC remote mode, using the same intuitive layout as the touchscreen on the polarimeter. The PC stores measurement results as a local copy in the database, so your data is retained after the polarimeter is switched off. Various data filters allow you to send data in Excel or HTML to your printer or export it in PDF format.
Semiautomatic sampling
The P8000-DT features a temperature-controlled micro-cuvette that can be used in flow-through operation. This is particularly useful for aggressive or expensive samples and substances, as are often used in the pharmaceutical and flavouring industries. The built-in rinsing and drying unit permits semi-automatic sampling, and subsequent cleaning using a hose pump and the integrated drying unit. This eliminates the need to remove the sample tube and clean it outside the polarimeter, for major savings of valuable sample substances as well as time. Cleaning is also possible through displacement by the new sample
