Optilab T-rEX

An on-line differential refractometer with EXtended range for universal concentration and dn/dc measurements.

The Optilab T-rEX provides both exquisite sensitivity and 50 times the dynamic range of every other RI detector available. It is the only on-line detector offering temperature control both above and below ambient, as well as measurement of the absolute refractive index of solvents. A high concentration version measures protein concentration up to 180 mg/mL.
