Setting the standard for high-level EPR spectroscopy

The ELEXSYS-II EPR spectrometer series is a research platform delivering outstanding performance and flexibility. The ELEXSYS-II EPR system is a complete series of spectrometer versions and EPR solutions – representing a fundamentally new approach to EPR instrumentation.
The ELEXSYS-II series provides solution oriented spectroscopy requiring an exceptional EPR software strategy and sophisticated hardware.

ELEXSYS-II Upgrade Pathways & Multifrequency

ELEXSYS-II spectrometers can be expanded with the DICE-II ENDOR equipment, the Imaging accessory, the FT system, and microwave bridges from 1 GHz to 263 GHz for CW and/or FT operation enabling real multi-frequency & multi-resonance EPR.


ELEXSYS-II is designed for open-ended expandability and has full network capabilities. A single user or a whole group can work with the system, whereby the members of the group may be at different locations.
The Client/Server architecture resolves the conflict between Multi-User/ Multi-Tasking on the one hand and real-time functions on the other hand.
With the ELEXSYS-II series we have introduced comprehensive software packages:

  • Aepr handles for 1D/2D data acquisition
  • Xepr for data display and processing
  • FDepr controls the DeviceNet, the high-speed communication between the server and the Functional Devices of the spectrometer
