Single wavelength polarimeter with XPC temperature control and low maintenance LED light source. Suitable for sugar, food, chemical and pharmaceutical industries.

XPC Temperature Control

Up to 200mm tube length

Standard ICUMSA tubes

Continuous or single-shot readings

Conforms to USP/EP/BP/JP (@589nm)

The ADP400 polarimeters are available with or without XPC – Xylem’s patented internal Peltier temperature control system. Both models use standard ICUMSA polarimeter tubes with a maximum length of 200mm.

These polarimeters contain proven optics, pioneered by Bellingham + Stanley, featuring “no maintenance” yellow LED and interference filter. Combined with a photodiode detector these technologies allow for the reading of samples of up to 3.0 OD at the commonly used sodium (589nm) wavelength. ADP400 polarimeters feature angular and sugar scales (ISS) and can be programmed with user scales as well as industry standard methods for displaying invert sugar, inversion (A-B) or when applying other factors such as tube length and concentration, Specific Rotation (or concentration when entering specific rotation). This flexibility makes them ideal for use within laboratories where compliance with Pharmacopoeia is required.

ADP400 Series polarimeters have a resolution of 0.001 angular degrees (°A) and are capable of reading to an accuracy of ±0.010 °A. When working under laboratory controlled conditions, ADP400 polarimeters also offer excellent reproducibility of up to 0.002 °A.

You can take readings with the ADP400 Series polarimeter in either continuous measurement or our new ‘single-shot’ mode. In continuous mode a reading is taken over a set period of time and a stabilised result displayed at the end of the period. It is excellent for monitoring instrument and sample stability, giving the user a “feel” for the reading obtained.

The ADP400 Series’ new ‘single-shot’ mode is ideal for pharmaceutical applications where a discrete value is provided without the interpretation of the operator, satisfying operating procedures where interpretation by a third-party, the operator, is not permitted.

ADP400 Series polarimeters come equipped with a new full colour 4” high definition display meaning results are clearly visible to the operator. The expanded memory ensures that over 8000 measurements and recorded logs of instrument configuration can be saved and viewed or output to LIMS or Secure PDF.

Calibration and configuration of the instruments can be 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.

The ADP400 Series polarimeters incorporate a number of industry standard interfaces making it easy to connect to peripheral devices including barcode readers, printers and USB memory sticks for external storage.
