Background: High resolution Nuclear Magnetic Resolution (NMR) Spectroscopy is a critical tool for the determination of the structure of molecules of biological interest such as proteins and nucleic acids. Ultra-dry, highly purified nitro- gen is required for a number of opera- tions involved in the use of high reso- lution NMR such as sample injection, sample spinning and sample lifting. While some systems employ a Dewar to supply the nit
