HP NMR tube

Picture of the High Pressure NMR tube

High pressure NMR tubes are used in NMR measurements with pressures from 1 bar to 200 bar. Typical experiments are:
- the study of reaction and equilibria involving moleculair gasses e.g. hydrogenation.
- Spectroscopy of supercritical fluid with critical pressure below < 200 bar and temperature < 150°C
The tube can be inserted into a conventional spectrometer.
