USA PTFE septa closure for chromatography vials

Vial inserts are used to reduce the capacity of the vial to accommodate smaller samples. Typically 150 to 400µL in volume, they may be made of glass, plastic, or a combination of materials. Closure options include those with and without septa, snap caps, screw caps, and crimp top caps.

metal HPLC needles. PTFE septa are not resealable and should not be used with highly volatile solvents, short cycle times or multiple injection methods. PTFE septa are rarely used for GC applications. Polyethylene (PE) Septa and Integral Molded Closures Chemically resistant polyethylene septa are usually molded into single-piece caps. The

The caps feature different finishes and septa materials for gas or high performance liquid chromatography applications. Maintain a clean and safe workplace using the spill-free chromatography vial closures available in various sizes and styles to be compatible with autosampler operation.

PTFE-faced silicone rubber septa are autoclavable, resist coring, and are recommended for use in all autosamplers using screw thread vials. Septa and liners can be laminated with PTFE on one or both sides to provide high chemical resistance and a nearly inert barrier between sample and septa material.
