Bellingham + Stanley, a Xylem brand, introduce the new RFM960-C Peltier temperature controlled benchtop refractometer, continuing their legacy of instrumentation to serve the lab market.

The RFM960-C delivers thermally stable results across a wide refractive index (RI) range: 1.30 to 1.70 RI and four decimal place resolution. This makes it ideal for users within the flavors, fragrance, chemical, petrochemical and particularly pharmaceutical marketplaces.  

The new refractometer incorporates the latest instrumentation technology, including a new 4” high-definition color display, providing a user interface that’s easily configured by the operator via intuitive set-up menus. Additionally, over 4,000 results can be saved or exported as secure PDF files via USB or Ethernet connection.

SMART thermal control rapidly equalizes the sample temperature and displays the result only when pre-set criteria has been reached, such as sample temperature stability being held to within +/-0.02 °C  for a number of consecutive readings.  

RFID swipe technology is standard on the RFM960-C, providing clearance and record of operator and configuration functions, which is especially useful when being used in FDA-controlled environments operating in accordance with 21 CFR Part 11, or where good practice is adopted, e.g. as part of HACCP.

Measurements with the RFM960-C are made through a normal measuring mode or by way of a simple Methods system with one-touch configuration of scale, temperature and data storage, with results being saved alongside pre-set limits that can be used as an audit tool. Methods may be user-defined or selected from the on-board library, such as the PHR-MEAN method that allows a number of individual readings from a single batch of pharmaceutical product to be measured with the resultant mean being displayed and recorded in accordance.

Methods for petrochem applications include ASTM D 1214, D 1747 and D 5006. Additionally, a method is included for ASTM D 2140 that requests external data input so that calculation of carbon-type composition of electrical insulating oil used in high-power transformers may easily be displayed and output.

The RFM960-C is as robust as it is technologically advanced. The prism dish is shallow with PEEK spill barriers, and an artificial sapphire prism and a Kalrez^® gasket protects the instrument against damage by harsh chemicals such as aromatic oils.
