NMR001: NMR Tube Specifications and Quality

The purpose of an NMR tube is to confine a liquid sample in a perfectly cylindrical volume in a magnetic field. Since this description is based on mechanics, it is not surprising that NMR tubes have been described by structural parameters for many years. The degree to which an NMR sample tube approaches the ideal ‘perfect cylinder’ defines the quality of the NMR tube.
