NMR Tube Cleaner

Congratulations to my student, Richard Marszalek, on his recent publication describing the NMR tube cleaner we developed (Landrie, C.L.; Marszalek, R.M. A Durable and Economical NMR Tube Cleaner. J. Chem. Educ. [Online early access]. DOI: 10.1021/ed200104v. Published Online: October 4, 2011.)  This apparatus can be constructed in less than 15 minutes from easily obtainable materials in the lab and at a significantly lower cost than the fragile glass apparatuses sold by commercial vendors.
