The NMR module is to be used with the ESR/NMR control unit (1022700 resp. 1022702) for investigating nuclear spin resonance in glyc-erine, polystyrene and Teflon.

The set consists of the factory-set base unit with the two magnetic coils, the NMR probe, glycerine sample, polystyrene sample, Teflon sample and an empty comparison sample. A measurement report is supplied with each NMR module. The resonance frequency for glycerine and the strength of the permanent magnetic net field for the respective module are specified in this report. An unambiguous assignment is guaranteed via the S/N on bottom of the device e.g. 203067-1, if several modules have been purchased.
