Abstract

An NMR (nuclear magnetic resonance) apparatus has a magnet system disposed 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), wherein part(s) of the probehead or the overall probehead can be cooled to cryogenic temperatures by supplying liquid nitrogen (5b) via a supply line (14). The nitrogen tank (3b) of the cryostat (1) is connected to the NMR probehead (8) by means of a supply line (14) in such a fashion that liquid nitrogen (5b) is removed from the nitrogen tank (3b) and guided to the NMR probehead (8). The overall apparatus is therefore more compact, the operating comfort of the apparatus is increased, and the costs for acquisition, operation and maintenance are considerably reduced compared to previous comparable devices.
