Digital polarimeter 589nm ±355 °A | ±0.01 °A | Peltier | ADP450

single-wavelength

The ADP450 with XPC technology is a single wavelength polarimeter ideally capable of measuring up to 3.0 OD at 589nm over a length up to 200mm. The ADP450 offers 3-decimal place precision to an accuracy of ±0.01 °A, making it ideal for general purpose use in food, flavours, fragrance, pharmaceutical and chemical industries as well as within academia and research. Key to the ADP450 is XPC technology. Standard polarimeter tubes are used to contain the sample. Interchangeable XPC adaptors allow the user to slot the standard tube into the instrument for measurement. Then XPC controls the system temperature by using powerful Peltier devices now in contact with the sample tube. No more water bath. No need for electronic temperature compensation. The ADP450 features a choice of “single-shot” or continual measurement of optical rotation or other related parameter such as specific rotation; concentration or inversion. Single-shot measurement is achieved by placing the polarimeter tube in to the chamber. The instrument senses the change and instigates the reading. Intelligent software monitors temperatures around the system and only provides the result when the sample has stabilised. Results are clearly seen on the instruments full colour 10cm HD display and over 8000 measurements as well as a record of the instrument’s configuration may be stored, viewed and output to LIMS or Secure PDF. Calibration and configuration of the ADP450 is password protected, accessible by keypad entry or for convenience, using a fully configurable RFID tag. This, together with the audit trail, facilitates operation in environments conforming to FDA regulation 21 CFR Part 11 or GLP.
