A sample holder for fixing and transporting a sample vial ( 1 ) within an NMR configuration comprising an outer shell ( 4 ) and a continuous hollow space disposed inside the outer shell ( 4 ) and extending along its axis for receiving the sample vial, is characterized in that a clamping device that can be switched on and off and a switching element ( 6 ) are provided inside the hollow space, wherein, in the activated state, the clamping device fixes a sample vial ( 1 ) that is introduced into the sample holder, the switching element ( 6 ) can be operated from the outside, and the clamping device can be deactivated using the switching element ( 6 ) such that, in the deactivated state, the sample vial ( 1 ) inserted into- or removed from the sample holder is not fixed. Such a sample holder may be used to realize an automatic supply device for changing NMR sample vials which has a very compact structure and can be mounted using little space.
