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.

Constricted Vacuum Tube and Tip-Off Manifold
Constricted NMR tubes offer the most convenient way to flame-seal an air-sensitive sample. Simply apply vacuum to the tube using our Tip-Off Manifold, and then heat the constricted portion and twist off to seal the sample in tube. Order a constricted NMR tube by adding “CONS” to the product number of any Wilmad sample tube. Example: 507-PP-7CONS.
