Bellingham + Stanley : What instruments for the réfractométrie and the polarimétrie?

Bellingham + Stanley, a Xylem Analytics brand, designs benchmark refractometers and polarimeters for QC, R&D and production laboratories. From handheld OPTi instruments to fully automated benchtop systems such as RFM-T and ADP600, the range combines state-of-the-art optics, Peltier temperature control and compliance features (audit trail, user management, 21 CFR Part 11). Industries served: food & beverage, pharmaceuticals, flavours & fragrances, fine chemicals. The aim: reliable, traceable and reproducible measurements, day in, day out.

Over a century of British precision optics

Founded in 1914 in the United Kingdom, Bellingham + Stanley was born from a passion for optics applied to physico-chemical measurements. By the interwar years, its refractometers and saccharimeters had become benchmarks across the sugar and beverage industries. The digital era accelerated its development: automatic instruments, Peltier temperature stabilisation, intuitive interfaces. Upon joining Xylem Analytics, the brand gained global reach while retaining manufacturing and expertise in Tunbridge Wells (UK). Today, it combines more than a century of know-how with contemporary technologies to serve regulated laboratories, from EP/USP/BP compliance to Industry 4.0. As part of Xylem, it pursues an ambitious, sustainable CSR programme.

Expertise and Areas of Specialisation

Its core expertise: measuring refractive index and optical rotation, with metrology-grade performance for demanding environments.

– Refractometry. The OPTi handhelds deliver rapid Brix and nD readings right on the shop floor. On the bench, the RFM-T integrate Peltier temperature control, a rugged prism cell and wetted materials engineered for solvents and viscous syrups. Result: accuracy, repeatability and thermal stability, with printing, CSV export and LIMS connectivity.

– Polarimetry. The ADP400 and ADP600 cover the needs of pharmaceutical QC and flavours: multi-wavelength capability, method management, temperature compensation and 21 CFR Part 11 functions (users, electronic signatures, audit trail). Ideal for EP/USP/BP/JP monographs.

– Traceability. Traceable quartz plates and reference liquids round out the range for regular calibration and daily verification (GLP).

Day to day, this blend of stable optics, processing algorithms and a clear, intuitive interface delivers accurate and reproducible results, in R&D as well as routine. That’s why Bellingham + Stanley is a trusted partner to food & beverage, pharmaceutical, fine chemical and fragrance laboratories, from goods-in inspection to batch release. Finally, the quality ethos shows in rigorous UK manufacturing, qualified after-sales support and options for traceable calibration in line with best practice. Network interfaces (USB/Ethernet), method management, acceptance limits and time-stamped reports make integration with internal procedures and data integrity straightforward.
