The RFM900-T Series refractometers are high precision instruments for use within petrochemical, pharmaceutical, flavours and fragrance industries. 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 stabilisation 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.

The RFM970-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).
RFM970-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 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.
