An NMR spectrometer (1′) has a sample changer (4′) with at least one cylindrical sample holder (7′, 7″) for receiving an elongated NMR sample at a loading position (5) and for transferring the NMR sample into the measurement volume at a transfer position (6). The sample holder is open in an upward direction and the cylinder axis of the cylindrical sample holder is inclined at the loading position by an angle of inclination a of between 30 and 60 degrees with respect to the vertical and it extends vertically at the transfer position. A positioning device is provided, which transfers the NMR sample at or after the transfer position into the measuring position in the measurement volume with a vertically aligned sample axis of the NMR sample. The spectrometer enables a more ergonomically favorable feed of the sample.
