PTFE Syringe Tubing

For Void-Free Filling of Viscous Solvents

These 12” lengths of PTFE syringe tubing provide an excellent means to access the bottom of small inner-diameter NMR tubes, enabling void-free filling with viscous solvents such as DMSO-d₆ or deuterium oxide.

This syringe tubing also permits easy retrieval of sample solutions from small-diameter NMR tubes or through the narrow orifice of valved NMR tubes.

The flexible, chemically inert PTFE tubing is supplied with a female Luer-lock hub on one end and a raw cut on the opposite end. The tubing can be easily cut and shortened to any desired length. The Luer-lock hub fits syringes with male Luer taper connections, whether locking-type or slip-tip configurations.

The Luer-lock hub is manufactured from Kel-F^® (PCTFE or polychlorotrifluoroethylene), which provides excellent chemical resistance, mechanical strength, and deformation resistance.

Both PTFE and Kel-F^® construction materials are virtually impervious to all common solvents, making the assembled syringe tubes washable and reusable for extended service life.

The table below presents several different gauge diameters of PTFE tubing, compatible with all Norell^® NMR tubes except 1 mm OD. Individual sizes may be purchased separately or as a complete kit containing one of each size. Upon request, additional gauge sizes from 30 to 7 are available, as well as custom lengths with female hubs on one end only or both ends.
