Bellingham + Stanley ADP430 Polarimeter

Single wavelength polarimeter with low maintenance LED light source.

The ADP400 Series are general-purpose single wavelength polarimeters suitable for sugar, food, chemical and pharmaceutical industries.. use standard ICUMSA polarimeter tubes with a maximum length of 200mm. For fast performance in the

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.

Both instruments 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.

Three decimal place precision makes for reliable results

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.

Additionally an easy-to-use Methods system gives convenient access to popular measurement types including continual measurement of Optical Rotation, Specific Rotation, Concentration, Inversion, or our new “single-shot” measurement which gives a snapshot result at any given time.

Continuous or discrete “single-shot” reading with SMART temperature stability

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.


The ADP600 Polarimeter comprises six models varying only by the wavelength of measurement, including the highly sensitive ultra-violet region.
