Description

How to make sealing your NMR/ EPR tubes easy!
If you struggle preparing NMR/EPR samples of air-sensitive mixtures, there is a simpler way! Use our NMR/EPR Tube Tip-off Manifold. You'll find vacuum transfers, freeze-pump-thaws and sample sealing easy to complete. Fuse the manifold port quickly to your vacuum rack. The chemical resistance is excellent, only Viton®, PTFE and Pyrex® come in contact with your sample. Tube connects to a threaded aluminum bushing isolated from the vacuum by a PTFE high-vacuum rotary valve. A twist of the wrist opens and closes both the rotary valve and port bushing.

 

 To add constriction on other size tubes, please specify the product number and fill out the quoting form here.
