Item 2995BB HPLC - Wyatt Optilab Rex RI Detector

Wyatt Optilab REX RI Detector

  • Model TREX-02
  • Universal detection for chromatography and FFF separations.
  • dRI measurement range, -0.0047 to +0.0047RIU
  • High resolution, touch-screen front panel display

The Optilab T-rEX (refractometer withextended range) is a unique dRI detector for standard HPLC/GPC with 256 times the detection power and 50 times the dynamic range of otherRI detectors for chromatography in existence today, making it a valuable addition to any MALS setup. The Wyatt Optilab REX detector can measure theabsoluterefractive index of a solution as well as thedn/dcof a solvent at thesamewavelength of light as the light scattering instrument. The light source in the T-rEX can be replaced for other wavelengths (e.g., 690, 633, 488, etc.) in just minutes.

All of our equipment is used and reconditioned. Our technicians test all equipment to confirm that it operates properly. While we can’t test for a specific analytical application, we will do our best to simulate the conditions under which the equipment will be run. If you have particular testing requirements or requests please let us know and we’ll work with you to make sure these requirements are addressed during testing.
