ADP430/ADP450

Bellingham + Stanley ADP400 Series Polarimeter

The ADP400 Series polarimeters are single wavelength polarimeters with a low maintenance LED light source. These polarimeters are available with or without Peltier temperature control.

The ADP400 Series from Bellingham + Stanley are single wavelength polarimeters suitable for sugar, food, chemical and pharmaceutical industries. These polarimeters are available with or without XPC - Xylem's patented internal Peltier temperature control system. Both models use standard polarimeter tubes with a maximum length of 200mm. For fast performance in the Peltier controlled version, stainless steel tubes should be used. Low volume samples are also catered for with the addition of stainless steel, luer taper tubes.

Bellingham + Stanley ADP440+ Polarimeter

The ADP440+ is single wavelength, high accuracy polarimeter

The ADP440+ is single wavelength, high accuracy polarimeter suitable for use in many applications and is especially suited for use in pharmaceutical laboratories where compliance with Pharmacopoeia¹ is required. New optics featuring a 'no maintenance' yellow LED and interference filter together with a photodiode detector allows reading of samples of up to 3.0 OD. The instrument has both angular and sugar scales (ISS) and can be programmed with user scales as well as industry standard methods for displaying concentration and specific rotation directly.

OPTi digital handheld refractometer

Bellingham + Stanley OPTi Digital Range Refractometer – Life Science

OPTi Digital Range – Life Science

Refractometers play a small but vital role within the life science sector for both human and veterinary use. Whether the need is to control the sugar content of sports drinks prior to consumption or to track hydration levels of athletes taking part in a sporting event, the duo scale OPTi-Sport is the right tool for the job. Similarly in the veterinary field, the OPTi-Vet is used to ascertain sugar levels of animal urine, large and small, as part of a diagnostic procedure.

Bellingham + Stanley ADP410

Bellingham + Stanley ADP410 polarimeter

Automatic Digital Polarimeter

Since 1996, the ADP range of polarimeters has become one of the world's most popular general-purpose automatic polarimeters. Building on the experience gained over the past decade of polarimeter design, Bellingham + Stanley continue the tradition by introducing the ADP410, incorporating up to date technology and delivering a high quality instrument at an affordable price. The ADP410 provides all the measurement performance of its predecessor, the ADP220, but with less software features.

RFM 900T Refractometers

Bellingham + Stanley RFM900-T Refractometers

Peltier temperature controlled refractometers with wide measuring range and 6 decimal place RI precision

Launched in 2015, the new RFM900-T Series refractometers combine latest opto-electronic principles with durability and ease of use via a touchscreen user interface.

Pro_juice_367

Bellingham + Stanley Pro-Juice Refractometer

Ultimate measurement performance for re-constituted orange juice

For many years, beverage manufacturers have adopted digital refractometers as their primary instrument for measuring the final dilution ratio (°Brix) of re-constituted fruit juice not only to assure product quality but also in an attempt to reduce losses by tightly controlling concentrate yields.  However, due to the nature of the sample, common refractometers show a variation in the reading caused by sample settling.  The Pro-Juice refractometer conditions the sample prior to measurement allowing for extremely precise analysis to be made allowing for higher yields from concetrates that translates directly to increased profits for orange juice packers.

abbe5 refractometer

Bellingham + Stanley Abbe 5 Refractometer

Ideal for practical demonstrations and experiments in chemistry and physics laboratories of schools, colleges and universities

The Abbe 5 is an affordable refractometer ideally suited for use where a wide refractive index measurement range is required such as in small contract laboratories or applications where sample throughput is relatively low. The instrument is also ideal for practical demonstrations and experiments in chemistry and physics laboratories of schools, colleges and universities and is the perfect partner to the new Model D7 optical polarimeter.

Abbe 60 refractometer

Bellingham + Stanley Abbe 60 Series Refractometers

High specification optical refractometers for specialist and research applications

Abbe refractometers date back to the birth of opto-mechanical instrumentation when Ernst Abbe created an instrument to categorise the behaviour of glass that was to be used in the first microscopes created with his then partners Otto Schott and Carl Zeiss. 

Today Abbe refractometers are still used in "purist applications" especially where measurements are required at wavelengths other than sodium or where solids are to be assessed such as measuring the dispersion of glass, polymers and even hydrocarbons.  They are also used to measure liquid anasthetic.

Bellingham & Stanley ADP600 Series Polarimeter

Bellingham + Stanley ADP600 Series Polarimeter

High precision, Peltier temperature controlled polarimeter series covering six wavelengths across UV/Vis spectrum (325-589nm)

Available as single, dual and multiple wavelength derivatives not only covering the visible spectrum, the ADP600 Series of Peltier temperature controlled polarimeters are capable of measuring optical rotation to four decimal places in the highly sensitive ultra-violet region. This capability makes the instrument particularly suited for use by scientists wishing to measure chiral compounds and other optically active substances in the chemical, pharmaceutical and food sectors as well as for use in academic research.

ADS400-Flow

Bellingham + Stanley ADS400 Series Saccharimeters

Simple cost effective standalone saccharimeters or purity systems

ADS400 Series saccharimeters are ideal standalone instruments measuring the optical rotation of sugar cane or beet durng payment, milling or refining processes or when connected to an RFM refractometer by way of simple PC program as part of a sugar purity system.  The user interface comprises an LED display with tactile push buttons identified with clear iconography that makes for simple operation by skilled and non-skilled users.

Sample is applied using standard polarimeter tubes for the lab with funnel flow through versions  available for rapid sample handling in the Tare House.  Sodium (589nm) and NIR (850nm) single wavelength versions are available, the latter facilitating measurement of dark samples without the need for lead based clarifiers.
