DXR3 Flex Raman Spectrometer overview

The Thermo Scientific DXR3 Flex Raman Spectrometer is a research-grade benchtop Raman spectrometer specifically designed for integration with other analytical techniques. This compact spectrometer uses the same design and optics as advanced spectrometers in the Thermo Scientific DXR3 Raman Spectrometer research product family. Thus, it provides transportability and hyphenation without compromising data quality. Whether you need to complement your materials understanding with chemical identification, correlate chemistry and materials performance, or monitor a process in real time, the DXR3 Flex Raman Spectrometer can help you quickly reach your goals.


DXR3 Flex Raman Spectrometer capabilities

Often referred to as “Raman engine,” the DXR3 Flex Raman Spectrometer offers research laboratory-level spectroscopic performance. It includes an open architecture that allows custom coupling to almost any equipment in any position. This coupling eliminates the need for multiple measurements and assumptions, enabling users to get quick and accurate answers.


Data captured simultaneously under the same condition from multiple techniques enables researchers to obtain the precise, reliable data they need. This makes it possible to learn about a sample’s physical, chemical, and structural characteristics and how they affect one another all from one measurement.

Other features include:

  • Configurable excitation laser wavelengths and spectral resolution to maximize performance for particular materials
  • Free-space optical coupling that maximizes sensitivity by eliminating fiber optic losses
  • A variety of accessories including fiber optics coupling, macro and micro sample holders, objectives, camera, and more
  • Lasers shareable and exchangeable with Thermo Scientific DXR3 Raman Microscopes
  • Thermo Scientific OMNIC Software, data, and spectral library compatibility with DXR3 Raman instruments; OMNIC D/S Software offers 21 CFR Part 11 compliance
