One of the most important quality control methods used in the pharmaceutical, chemical, cosmetics, food and beverage industry is polarimetry - optically active substances are analysed by determining their angle of rotation. The angle of rotation allows you to ascertain the identity and quality of substances as well as their concentration in mixtures. It can also indicate the progress of reactions and conversions. Polarimeters are used in a wide range of applications -from the determination of the purity and concentration of ingredients in pharmaceuticals to the maturity testing of...

FOCUS ON QUALITY WITH POLARIMETERS FROM A.KRÜSS

If the maximum functional range is desired but a temperature control of the sample for high-precision measurements not required, our polarimeter models P8000 and P8100 will be the right choice. They only differ in their measurement accuracy when measuring the optical rotation, all other features are identical. The devices are very robust and yet precise and suitable for nearly all samples as the parts that come in contact with the sample are chemical-resistant. The P8000 and P8100 are especially recommended in case of a high sample throughput in the sugar industry. Instead of a temperature...

The polarimeter models P8000-T and P8100-T have the same functional scope as the P8000 and P8100 but will also allow for a water bath temperature control in the range between 8 and 40 °C when combined with temperature-controlled measurement tubes such as our PRG-100-ET. That makes them suitable for high-precision measurements as they are, for example, required in the pharmaceutical industry. 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 se I ection of this type of tubes....

POLARIMETERS WITH PELTIER TEMPERATURE CONTROL – P8000-P AND P8100-P High-precision measurements through temperature control without an additional device – this is what our polarimeter models P8000-P and P8100-P offer, which otherwise have the same functional scope and the same characteristics as the other devices of the P8000 series. They are recommended if the temperature of the sample is to be controlled extremely accurately within a very short period of time and with a short control cycle and independent of the outside temperature. This also requires the measurement tube PRG-100-EPT...

MAXIMUM EFFICIENCY THROUGH AUTOMATION SAMPLE SUPPLY OPTIONS MANUAL FULLY AUTOMATIC We offer a large selection of measurement tubes for manual operation. While filling the sample into the tube via a funnel or the opened screw connection on the side, you check whether the filling is free of bubbles. For cleaning purposes, the tube is removed, unscrewed at the sides and rinsed with the appropriate medium until all sample residues have been dissolved and eliminated. Semi-automatic operation requires a P8000-TF/P8100-TF with flowthrough function and drying unit DS7060, a flow-through measurement...
