A transport device for transporting an NMR sample to the probe head (16) of an NMR spectrometer by means of a transport system (12) is characterized in that the transport device comprises a shuttle (15) adapted for use with a transport system. The transport system is structured to transport an HR-NMR sample spinner or an NMR MAS rotor (5). The shuttle includes a locking device for the NMR MAS rotor, the locking device being formed such that the NMR MAS rotor is released by unlocking the locking device and can be transferred to and received by the NMR MAS probe head. It is therefore possible to rapidly change from NMR spectroscopy of liquids to NMR spectroscopy of solids, and vice versa, simply by exchanging the probe head, without converting the transport system.
