For preparation of Air-Sensitive NMR sample mixtures. Vacuum transfers, freeze-pump-thaws and sample sealing is easy to complete.
The manifold port can be fused quickly to a vacuum pack. Chemical resistance of the manifold ports is excellent; only Viton, Teflon and Pyrex can contact the sample mixture.
The NMR tube connects to a threaded aluminium bushing which is isolated from the vacuum by a Teflon high vacuum rotary valve with Viton o-rings. A twist of the wrist opens and closes both the rotary valve and port bushing.
