Digital Refractometers & Polarimeters FOR PRECISE MEASUREMENT OF CONCENTRATION AND PURITY

Feature Key 21 CFR Part 11 Peltier Temperature Control RFID User Identity Factory Friendly USB Connectivity HD Colour Display What is Refractive Index? When light passes from one medium to another, the speed at which the light travels will change depending on the parameters of the materials. This principle can be seen when looking at a straw in a glass or an oarsman on the river, as shown in the diagram. The ratio or change in the speed of light is called refractive index and instruments that measure this are called refractometers. The refractive index of a liquid is related to its...

RFM700 Refractometers RFM700 series refractometers are robust, low cost, fully automatic instruments that are ideally suited to the food, sugar and beverage industries but can also be used in many other non-food applications where temperature control is not required. Commonly, the RFM700-M series refractometers are supplied to operate in the °Brix scale with results temperature compensated to 20°C in accordance with ICUMSA. Additional user scales provide measurement in different formats such as Refractive Index (RI) various wine, urine specific gravity & automotive scales as well as...

RFM300 Refractometers The RFM300 Series of refractometers are the result of a combination of over 100 years’ experience in design and manufacturing led by customer needs. With a wide measuring range and Peltier temperature control of the flat, easy clean prism, the RFM300 Series refractometers offer extremely rapid temperature stabilization of the sample, allowing readings to be taken quickly and reliably in any scale including Brix, Refractive Index (RI) or up to 100 user defined scales. Whether a high resolution 7” touchscreen (RFM300-T) or a more tactile keypad (RFM300-M) is required,...

offset from within the Methods system, can express finished beverages as an equivalent SG. By doing so, contract packers of beverage products may now use a refractometer in situations where density °Brix or SG is dictated as the method of analysis, whilst retaining all the measurement advantages held by a refractometer. A dual display function allows original Brix or RI to be displayed alongside the equivalent sucrose SG result. Other new features now standard on the RFM300 Series include RFID User Clearance, electronic signatures and audit trails that facilitate use in an FDA regulated...

RFM900-T Refractometers Featuring a new touchscreen display and wide measuring range up to 1.70 RI and capable of measuring to six decimal places, the RFM900-T Series refractometers are ideally suited for use in the chemical, petrochemical, pharmaceutical, flavours and fragrance industries as well as for academic research. The RFM900-T series of refractometers combine the latest optoelectronic principles with durability and ease of use. RFM900-T refractometers feature RFID (Radio Frequency Identification) that allows users to identify themselves by simply swiping a tag across the top of the...

• Pharmaceutical • Chemical • Widest RI range • Highest precision (±0.000005 RI) • MEAN Method (USP/EP/BP) • All RFM900s conform to ASTM D 1218, 1747, 2140 & 5006 taken when the sample and refractometer temperatures are both stable. The instruments conform to a number of industry measurement standards and offer operational features that allow use in an environment controlled by FDA regulation 21 CFR Part 11. The use of a Kalrez® gasket and sapphire prism facilitates placement in the harshest measurement environments including those in the pharmaceutical, petrochemical, aroma, flavour,...

ADP400 Polarimeters The ADP400 Series of general-purpose, single wavelength polarimeters are suitable for sugar, food, chemical and pharmaceutical industries where measurement is required to 3-decimal place resolution (°A) over a length between 10 and 200mm. The ADP400 polarimeters are available with or without XPC - Xylem's patented internal Peltier temperature control system. ADP400 series polarimeters feature a 'no maintenance' LED light source and interference filter with photodiode detector technology that provides sample readings up to 3.0 OD at the commonly used sodium (589nm)...

Servlce/Inspection Is due vnthlr next 5 days ADP400 Series polarimeters now feature a full colour, 4” (10 cm) high definition display. Measurement may be expressed as angular degrees (°A), sugar (ISS) or user programmable scales, with standard Methods facilitating display of invert sugar, inversion (A-B) or, when applying other factors such as tube length and concentration, Specific Rotation (or concentration when entering specific rotation). The ADP400 Series offers both continuous and 'single-shot' reading modes, the latter being ideal for pharmaceutical applications where a discrete...

ADP430 polarimeter The ADP430 is a fully featured instrument designed for use in applications where internal temperature control is not required or where the use of automatic temperature compensation or a water bath is preferred, such as within the food industry. ADP450 Polarimeter The ADP450 polarimeter with patented XPC technology features interchangeable contact Peltier plates facilitating measurement at a stable temperature using Peltier control. XPC technology conveniently stabilises the temperature of the sample being measured. With SMART temperature stability enabled, the ADP450 will...
