Abstract
A new high‐pressure NMR probehead designed for a 400 MHz widebore NMR spectrometer is described. For the first time, the electrical leads of the rf circuit, the tubes for the thermostating liquid and the high‐pressure fluid, as well as the wires of the Pt‐100 resistor for temperature control, are all fitted at the bottom of the high‐pressure vessel. The sample can easily be removed through a top plug, which allows a relatively fast exchange of the sample. A rather simple design leads to a low‐cost construction. The high‐pressure vessel and the rf circuit are placed inside a standard probehead jacket, such that the high‐pressure probehead can be fitted into the superconducting magnet in the same way as a commercial probehead.
