Good Laboratory Practices for NMR Lab BE001


Because the NMR facilities in our department are valuable resources and are shared by many users, the Chemistry Department requires users of its NMR instruments to adopt practices that help maintain the equipment and to use the facility in a safe and effective manner.  The information below is provided to help accomplish these goals.


Lab BE001 has three superconducting NMR magnets located in it.  These magnets project strong “stray” fields into adjacent space about their circumference, and above and below the cryostat vessels.  These fields can affect certain electronic devices, persons with metallic implants and magnetic storage media.


More significantly, these fields will accelerate iron or other ferrometallic items toward the magnets.  This is a potential hazard for the equipment and for persons in the path of such an item.  Examples might include gas cylinders, tools, fire extinguishers, loose paperclips, razorblades, staples etc.


We can mitigate the magnet hazard by prudent practices. 








Clutter both of a general nature and especially chemical clutter is not compatible with a safe NMR facility. 








We cannot permit eating or drinking in the lab. This is both for your personal safety and that of others, and will help protect the equipment from spills, crumbs and grease.  This is in line with the University Chemical Hygiene Plan.


Safety glasses are required in all laboratories.  These will be provided for NMR lab, or you may wear your own. 


NMR tubes frequently transfer dirt to the inner surfaces of the probe.  Minimize this by:






It will speed the action of the robotic shimming adjustments if solution volumes are normally prepared to a uniform height.  To achieve this, I strongly suggest that 0.8 mL (800 mL) of deuterated solvent be the norm.
