A simple NMR tube cutting aid. This was designed to shorten NMR tubes filled under protective gas (to access/retrieve crystals near the bottom). The whole thing fits through a NS29 ground glass connection to maintain the protective atmosphere and also works with our muCHILL inert microscopy cold stage as shown in the pictures (published here: https://journals.iucr.org/j/issues/2018/02/00/gj5200/gj5200.pdf).
One M2x12 screw and M2 nut needed for assembly.
Usage:
- Start by scoring the NMR tube all-around, using a glass cutter. Make sure you will not spill solvent upon cutting.
- Place NMR tube in tool, align score mark with line on tool (red arrows).
Note: the tool will hold the tube, but press only VERY GENTLY! - Transfer to Schlenk vessel or other target platform (optional).
- Slightly increase pressure until it snaps.
- Remove tool with upper piece, note that the tube part below the cut is loose and can freely detach. The tool will grip the upper piece.
