The DiffBB is a broadband gradient probe optimized for very strong gradient pulses up to 17 T/m, designed for samples in 5 mm sample tubes. The DiffBB offers a 1H-19F, a broadband XBB and a lock channel in a wide temperature range from -100°C up to 180°C.

Standard Bore Probe with a Sample Diameter of 5 mm, a  Max. Gradient strength of 17 T/m and a Diffusion Coefficient < 1 x 10-14 m²/s.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 1x10-14 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.
