The Diff50 gradient system is a high-power gradient system for diffusion applications in wide bore magnets, optimized for very strong gradient pulses and fast switching times.

The Diff50 high power MR Diffusion  probe provides exchangeable single or double tuned frequency ref coils. The Diff50 offers the highest gradient strength available at Bruker for diffusion coefficient measurements down to 5.10-15 m2/s (under specific conditions). The sample can be temperature controlled between -40°C and +80°C, probe body and coils (<= 8mm) are compatible with the Micro5 probe. 

Often double tuned rf coils with 2H on the outer coil are selected to allow for locked or TopShim applications. In this configuration, only one nucleus is available for the NMR experiments.

A special version of the Diff50, the Diff50L, has 2 rf coils for NMR investigations plus lock channel. In this configuration the rf coil is not exchangeable anymore, the frequency combination must be defined on initial order of the probe.
