Dual-action NMR tube cleaners
 |
- For high volume cleaning, no o-rings needed
- Specially designed to prevent accidental breakage of tubes
- Highly efficient solvent jets improve cleaning and reduce solvent usage
- For 7 or 8in. L, 5mm NMR tubes

Five-position NMR tube cleaner system
Washes up to five 5mm, 7 or 8in. L NMR tubes at once (Figure 1). NMR tube caps can be used to plug holes if less than five tubes are to be cleaned. Cleaning solvent is pulled from an external container via PTFE tube, eliminating repetitious filling of side mounted reservoirs. Note: Bottle for cleaning solvent is not included.
- Totally inert, cleaning solvents contact borosilicate glass and PTFE
- No ground joints to freeze, eliminates grease
- Top PTFE tube holder provides a vacuum-tight seal
- Modular components are easy to replace
Simple to use:
- Slide O-rings approx. 25mm down on NMR tubes
- Insert NMR tubes into top adapter
- Turn on vacuum, make sure all O-rings are seated in top adapter
- Open solvent valve to wash tubes
- Turn solvent valve 90° to air dry tubes
