A new design for an in-situ combination of NMR and rheological measurements is presented. The NMR is based on a BRUKER MINISPEC spectrometer. The magnet is self-made via a construction of 64 permanent magnets in a so called MANDHALA arrangement. The magnetic field strength reaches about 0.23 T, corresponding to a 1H resonance frequency of about 9.5 MHz. For the in-situ rheological measurements a Scarabaeus SISV50 instrument with modified sample cells is utilized. This unique combination and first measurements are presented.
