PolAAr 30-3000, 31-3001
Offers high quality, high accuracy, high reliability, clear digital display, flexibility of use, plus detailed GLP traceability of results. Its all metal construction is based on an incredibly stable aluminum casing with metal covers. The principle of measurement used in the PolAAr 3 series was patented by Optical Activity, Ltd. in 1976, and the original advanced design, which won a Queen's Award for Technological Achievement, has been refined by Optical Activity through many years of experience in polarimetry.
All models in the PolAAr 3 series accept the full range of activity polarimeter sample tubes and cells from 1.5mm to 8mm bore, from 5mm to 200mm path length, jacketed or unjacketed. The sample compartment is ventilated to minimize temperature rise above ambient. For the most accurate temperature control, jacketed sample tubes are available for temperature control from a thermocirculator. These tubes are available with built in temperature sensors to accurately monitor sample temperature. A dip-in thermometer is available for use with single sample tubes.
The difference between the PolAAr 31 and the PolAAr 3001 is the resolution. The PolAAr 3001 is our highest accuracy model. It reads to 0.001 angular degrees of optical rotation and displays results within 25 seconds.
When connected to an Index Instruments refractometer the PolAAr 3001 combines the ISS and Brix readings and calculates and displays apparent sugar purity.Specifically for the sugar industry.
