Optilab® UT-rEX™ Refractive Index Detector, Wyatt Technology Corporation (CAT#: STEM-LE-2013-LC)

The Optilab® UT-rEX brings the universal detection capabilities, unmatched concentration range, and excellent sensitivity and linearity to the domain of UHPLC.

Temperature Range:4°C to 65 °C
Type:Refractive Index Detector
Sensitivity:± 0.002 RIU
Light Source:660 nm standard (other wavelengths available)
Principle:UHPLC Compatible
Dimensions:(WxDxH) 36 x 60 x 17 cm
Refractive Index Range:1.28 to 1.8 RIU
Cell Volume:7.4 µL
Wavelength(s):660 nm

Less than 4 µL band broadening to maintain the resolution of very narrow UHPLC peaks
Extraordinary dRI measurement range, -4.7 x 10-3 - +4.7 x 10-3 RIU (comparable to 25 mg/mL protein in PBS)
Highly sensitive, ± 1.5 x 10-9 RIU over the whole measurement range
Measures solvent refractive index, require for MALS calculations
Measures at the same wavelength as the MALS detector, for maximum accuracy in MALS calculations
Temperature range 4°C - 65°C for proteins and polymers that require a range of temperatures
High-resolution, touch-screen front panel displays data graphs and instrument diagnostics, even with the host computer turned off
