NMR Tube Holders

As part of our ensemble of electrolyte characterization methods, nuclear magnetic resonance (NMR) spectroscopy samples must be placed in long glass NMR tubes. Typically, I collect these NMR tubes in a beaker, but I felt so inspired by this tweet from Romero Lab at UCSD, that I took to Blender and Solidworks to design and print my own family of NMR tube holders.
