High Precision Instrument
The RFM900-T Series refractometers are high precision instruments for use within industries such as:
- petrochemical
- pharmaceutical
- flavours
- fragrance
The ergonomically designed cases deal with any spills by the sloping shape of the case or by the PEEK spill barrier that surrounds the shallow, easy-clean stainless steel prism dish. The prism dish is shaped to hold sufficient sample for measurement whilst regaining a large enough surface area for rapid temperature stabilization to occur.
A Kalrez® gasket compliant with FDA / USP Class VI has been chosen as the prism seal due to its traceability and its almost impermeable nature to most chemicals. The sample cover forms a seal to prevent evaporation, particularly important when working with volatile solutions such as aromatic oils and is interchangeable so that a presser type can be fitted for more viscous samples.
Inherent to the design is the high definition, capacitive touchscreen display that not only facilitates operation in factory environments, even when operated whilst wearing gloves but also serves as the centrepiece for the new software. Combined, the touchscreen and GUI help the operator quickly manoeuvre through the user and configuration menus. On-screen graphical prompts support simple operations such as method loading, calibration and routine maintenance.
The Technology
RFID swipe technology comes as standard, providing clearance and a log of operator and configuration functions – especially useful when being used in FDA-regulated environments operating in accordance with 21 CFR Part 11, or where good practice is adopted, e.g. as part of HACCP.
Measurements with the RFM900-T are made through a familiar measuring mode or by way of a simple Methods system with the one-touch configuration of scale, temperature and data storage, with up to 8000 results being saved alongside pre-set limits that can be used as an audit tool. Methods may be user-defined or selected from the onboard 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.
The RFM960-T Refractometer is particularly suited for operation within pharmaceutical environments, used to measure the purity of incoming raw materials as well as for production quality control in accordance with pharmacopeia (BP/EP/USP/JP).
RFM960-T refractometers may also be fitted with an optional flow through cell so that it may be used as part of a pharmaceutical pilot or full scale manufacturing process. This is because wetted materials traceability is made easy due to the FDA/USP Class VI components used as the standard for areas where the sample is in contact with the instrument or flowcell. Materials Certificates for both refractometer and flowcell wetted materials are available.
