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.
