<p>An NMR (nuclear magnetic resonance) apparatus comprising a magnet system that is arranged in a cryostat 1, the cryostat having at least one nitrogen tank 3b for receiving liquid nitrogen 5b, and a room temperature bore 7 for receiving an NMR probehead 8 with a transmitting and receiving system 9, wherein parts of the probehead or the overall probehead can be cooled to cryogenic temperatures by supplying liquid nitrogen 5b via a supply line 14, is wherein the nitrogen tank 3b of the cryostat 1 is connected to the NMR probehead 8 by means of the supply line 14 in such a fashion that liquid nitrogen 5b can be removed from the nitrogen tank 3b of the cryostat 1 and be guided to the NMR probehead 8. The overall apparatus is therefore more compact and requires less space, the operating comfort of the apparatus is increased, and the costs for acquisition, operation and maintenance are considerably reduced compared to previous comparable devices.</p> |
