Bellingham and Stanley Refractometers Overview

Bellingham + Stanley Ltd. offer one of the largest choices of digital refractometer lab measuring instruments in the World today. All refractometers are made to the highest standard and with over 90-years of experience, are directly supported by a team of experts and by a global network of fully trained distributors.

RFM700 Refractometer

RFM700 Refractometer

Designed with ultimate simplicity in mind, RFM700 refractometers offer digital automatic technology at low cost. In 2007, new derivatives replace earlier models and feature more scale and temperature compensation options, enabling the instrument to be used not only in the traditional food, sugar, and beverage applications but also some industrial applications.

The new models are particularly suited to wine applications, as industry standard scales such as Baume, Oechsle, and Probable Alcohol (A.P.) can easily be downloaded from this Internet site. As well as wines scales, a new ‘Fuel System Icing Inhibitor’ scale that conforms to ASTM D 5006 can be loaded as well as refractive index (RI).

Physical benefits of the RFM700 include a flat ‘easy clean’ sapphire prism and a ‘no-presser design’ offers rapid cleaning once a measurement has been taken. A programmable measurement delay is also offered.

rfm340 lab

RFM300+ Refractometer

Launched in 2007, the RFM300+ series of refractometers is the result of a combination of excellence in design and manufacture dictated by customer needs.  Offering a wide measuring range, temperature control of the flat ‘easy clean’ sapphire prism is achieved by Peltier device, eliminating the need for a waterbath whilst offering extremely rapid temperature stabilization of the sample.

A powerful onboard microprocessor facilitates readout in a number of different scales including RI, °Brix, HFCS etc. and the simple to use secure menu structure can be displayed in a number of different languages.

The RFM300+ series of instruments is most suited for use in harsh factory environments in all manner of applications.

Abbe 60 Refractometer


Abbe Refractometer

The Abbe Refractometer derives its name from the 19th Century physicist Ernst Abbe (1840-1905). Abbe designed an instrument for measuring the dispersion of light and this became the precursor for the so-called ‘Abbe Refractometer’.

Bellingham + Stanley offer a number of Abbe refractometers and a choice can be made in accordance with the measurement requirement and budget availability.

Launched in 2006, the Abbe 5 offers direct refractive index and Brix readings at a low price and is ideal for academia as well as for general measurement within industry.

Abbe 60 refractometers are manufactured to extremely high standards and come in a variety of scale ranges to suit particular application requirements.

The Abbe 60/95 offers high-resolution readings within the Brix scale (better than ±0.2 Brix) and is used for the measurement of viscous corn syrups and sugars, whilst the Abbe 60/DR offers high refractive index measurement to 1.74 to 4-decimal places.

High accuracy, multiple wavelength versions (Abbe 60/LR and Abbe 60/ED) cover a refractive index range from 1.20 to 1.74 RI and require the use of ‘spectral lamp outfits’. As such, the instruments may also be used for measurements of dispersion over the visible spectrum and can provide results to five decimal places – the highest accuracy available with this type of instrumentation. The Abbe 60ED conforms to test measurement ASTM 1218.

The E-Line Gemological refractometer is a low cost, lightweight measuring instrument used exclusively by jewellers and traders of gemstones.

All Abbe refractometers are particularly suited to the measurement of solids and semi-solids such as thin film polymers, rubber, glass and fibre optics as well as liquid samples.

All instruments* feature a temperature control facility by way of waterbath connection and temperature measurement is made by integral sensor and displayed digitally (LCD).

‘Freeware’ for converting results to other scales and for calculating dispersion is available from this site.

ADP410 Polarimeter

The ADP410 polarimeter has been specifically designed for applications that require automatic measurement with a resolution to 0.01 but without the additional features of more expensive polarimeters. Both angular and sugar scales are available by simple push button operation with results available in 15 seconds by bright LED display or print function.

Full technical specification for ADP410

 

Purity System with ADS 420 saccharimeter

ADS420 Saccharimeter

The ADS420 Saccharimeter is a purpose built polarimeter designed for use in the sugar industry. It can be used as a single measurement instrument or may be connected to a refractometer via a PC to form a Purity System.

Full technical specification for ADS420

ADP220 Polarimeter

ADP440 Polarimeter

The ADP440 is a high accuracy polarimeter capable of giving results to 3 decimal places angular. High security software fulfils the operational requirements of FDA regulation 21 CFR Part 11, whilst the onboard software facilitates measurement in accordance with industry standard methods including PURITY, Specific Rotation, Concentration and inversion. The instrument conforms to the minimum requirement of USP/EP/BP.
