Cryo-magnet

Fig. 3.9 Schematic view of a Mbssbauer cryostat with a superconducting cryo-magnet for horizontal transmission experiments with the field parallel to the y-rays. Without a magnet the helium reservoir may end above the optical axis, such that the cryostat can have a narrow tail with much shorter window-to-window distance...

NMR instrument. A host computer, console, preamplifier, probe, cryo-magnet, pneumatic plumbing, and cabling that together allow the collection of NMR data. 

To measure NMR spectra, the molecules of interest are placed in a magnetic field generated by a cryo-magnet. In this way, the polarization of the nuclei is... 

Conventional NMR measurements are performed with samples in a 5 mm glass tube, which is positioned in the NMR probe by a rotor (Fig. la). The probe is located in the room temperature bore of the cryo-magnet in the position of the best homogeneity of the magnetic field. Glass tubes are interchanged by means of an air cushion, and this can be carried out automatically by robots.
