The DiffBB is a broadband gradient probe with the Automatic Tuning Module (ATM) for NMR diffusion investigations of a wide range of diffusivities down to 110-14 m2/s (T1 > 1s and T2 > 100 ms ). The DiffBB provides a high-performance water cooled single axis gradient. Variable temperature measurements are possible in the range of -40°C to +150°C. Together with the ATM this allows a series of fully automatic variable temperature experiments. The broadband channel enables to observe a wide range of nuclei from 1H down to 15N.
