NMR Service GmbH provides a REDOR Box, which splits a single X-channel (e.g. of a Bruker H-X MAS probehead) into a double-resonance circuit to enable X-Y REDOR NMR experiments, e.g.13C-23Na or 6Li- 2H.


Technical data

  • Up to 1.5 kW RF pulse power (50 µs)
  • VSWR < 1.2
  • For frequency differences between 1 MHz and 25 MHz (max.)
  • Efficiency of up to 80 % compared to the single X-channel
  • Compatibel and tested for Bruker H-X MAS probeheads
  • Easy installation/mounting directly to the probe
  • Easily exchangeable coupling coils inside the box
  • Enables huge experimental flexibility to achieve desired splitting

The REDOR Box is available for

  • 200 to 600 MHz magnets (large box)
  • 700 to 900 MHz magnets (small box)
