Polarimeters for the laboratory
The polarimeter models P8000-T and P8100-T will allow for a water bath temperature control in the range between 8 and 40 °C when combined with temperature controlled measurement tubes and a thermostat. That makes them suitable for high-precision measurements in quality control. Especially if a multitude of different temperature controlled measurement tubes are to be used, the P8000-T and P8100-T are the right choice. We offer a very large selection of this type of tubes.
- Temperature measurement directly inside the sample
- Accurate, homogeneous water bath temperature control
- Large selection of temperature-controlled tubes
- Quick coupling system for an easy measurement tube change
- Highest accuracy over the entire measurement range
- Very short measurement time of approx. 1 s
- Measurement up to an optical density of 3.0
- Intuitive operation via touch-screen display
- Predefined scales (opt. rotation, spec. rotation, int. sugar scale, concentration)
- Any number of freely definable scales with conversions based on tables or formulas
- Chemical-resistant materials
- Compliance with GMP/GLP, 21 CFR Part 11, Pharmacopeia (USP, BP, JP, Ph. Eur.), FDA, ISO, HACCP, OIML, ASTM, ICUMSA, NIST

Typical applications
The P8000-T polarimeters can be used for a variety of applications in the pharmaceutical, chemical, sugar, food and beverage industry, as well as for the production of flavors and fragrances.
- Determination of concentrations in raw materials, preliminary, intermediate and end products
- Purity control
- Determination of the stereochemical composition and mutarotation
- Monitoring of chemical processes
- Routine analysis with high sample throughput
A comprehensive overview of typical applications with the polarimeters of the P8000 series can be found in our campus article on polarimeter applications.
Conformity with national and international standards
A big advantage of normalized measurements is the comparability of the measurement results. In many international standards and guidelines, polarimeters are recommended for specific measurement tasks as suitable measuring instruments. The requirements for the measuring devices, such as measuring accuracy and measuring temperature, are dependent on the respective measuring task and defined in each standard. We have compiled for you an overview of all known standards and guidelines, which refer to polarimetry.
