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.
