Our new Model R-24 is a significant breakthrough in NMR instrumenta­tion. It is a high resolution instru­ment that provides high quality performance at a very low price.

The Model R-24 operates at 60 MHz —instead of at a lower fre­quency—to provide data in a form directly comparable to most pub­lished NMR reference spectra.

It provides better than 0.6 Hz resolution to meet the requirements of the most demanding analytical problems.

It has high S/N making possi­ble precise analyses at low sample concentrations.

Operation is so simple, that no special training is needed to obtain good NMR data. Thus it is ideal for

teaching laboratories, as well as for regular use in research, analyt­ical and quality control laboratories.
