Polarimeters overview

Bellingham + Stanley manufactures high quality ‘general purpose polarimeters’ for use in a variety of applications, along with a range of sample tubes and quartz control plates for instrument validation.


ADP220 Polarimeter

ADP600 Series Polarimeters

The ADP600 Series of Peltier temperature controlled polarimeters are designed to meet the needs of the most demanding applications within the chemical, pharmaceutical & food sectors making it an ideal instrument for scientists wishing to research the characteristics of chiral compounds.

The ADP600 Series comprises of six models varying only by the wavelength of measurement, including the highly sensitive ultra-violet region. All ADP600 series Polarimeters are capable of measuring to four decimal places at constant temperatures of temperatures of 20 & 25 °C, set by an integral METHODS system accessed via a high definition touch-screen user interface.

The ADP600 Series polarimeters are compliant with all elements of Pharmacopeia and are suitable for use in high security environments operating in accordance with FDA regulation 21 CFR part 11

ADP400 Series Polarimeter

ADP400 Series Polarimeter

ADP400 Series polarimeters not only offer three decimal place measurement, they are also packed full of features normally only expected from high-end instrumentation. 
There are two models:

  • the ADP450 with patented XPC technology that uses Peltier to control sample temperature.
  • the ADP430 for use where no temperature control is required or for operation with automatic temperature compensation (ATC) or a waterbath.

A METHODS system allows rapid instrument configuration.  Setting the scale, (optical rotation, sugar, Specific Rotation, concentration, etc.), selecting the reading type (continuous or single-shot) and limit checking against pre-defined product specifications is simple. 

High security software fulfils the operational requirements of FDA regulation 21 CFR Part 11, electronic signatures.  User access is configurable and protected with password entry via keypad or RFID tag.  Audit trails of readings and configuration are easily viewed on the 4” (10cm) full colour display or downloaded via USB or LAN/Ethernet.

Both instruments conform to the minimum requirement of USP/EP/BP for sodium (589nm) measurement.

Purity System with ADS 420 saccharimeter

ADS400 Series Saccharimeter

A Saccharimeter is a purpose built polarimeter that displays results in the ISS (°Z) scale. Bellingham + Stanley has designed a series of Saccharimeters in a choice of 2 wavelengths - Sodium (589nm) and NIR (850nm); available with or without XPC Technology - Xylem’s patented on-board Peltier temperature control system for measuring optically active samples at stable temperatures.

Designed with the sugar industry in mind.

Available as either:

  • Traditional Sodium wavelength (589nm)
  • Near Infrared NIR wavelength (850nm)

Both models feature low maintenance LED light source technology, 4” full colour display, and compatibility with RFM refractometers to create a fully automatic purity system. ADS Saccharimeters are available in a number of supply formats to allow for easy procurement and installation, whether for single sample analysis or as part of an automated Tare House receiving system.
