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.

Z422843 is our feature product in this category.
