PTFE/Silicone septum is provided with a thin 0.005” PTFE layer laminated to our high purity silicone and slit through the center to provide for easier needle penetration as well as to release the vacuum that forms when a large volume of sample is withdrawn from a vial.

High quality, silicone rubber laminated to PTFE. Use when excellent resealing qualities are a must. Septum resists coring and is recommended when multiple injections are required. Preferred septa for use in liquid chromatography applications.

Our closures with septa are made in a wide variety of sizes and materials ensuring you have the right combination for your sample type and analysis temperature. 9 mm Pre-Assembled Blue Polypropylene Screw Cap with Pre-Slit PTFE/Silicone Septa, 100/pk | PerkinElmer

The PTFE valve on the storage flask keeps solvent vapors away from the septum, thereby minimizing septum deterioration. Further, the stopcock allows for the replacement of the septa. PTFE will cold flow (creep) with time. Therefore, unattended long-term storage of a tightened PTFE stopcock or valve is not recommended.

For applications involving automated transport of vials, magnetic caps are recommended. The cap liner or septa is the part of the cap which establishes a tight seal with the vial. Liners and septa can be laminated with PTFE on one or both sides, which results in high chemical resistance and a nearly inert barrier between sample and septa material.

PTFE disk septa A solid disk of 0.010” thick pure PTFE offers superior chemical inertness against the most aggressive solvents. The thin membrane allows for penetration by most normal gauge metal HPLC needles. PTFE septa are not resealable and should not be used with highly volatile solvents, short cycle times or multiple injection methods.

Septa. A wide range of serrated and non-serrated septa, and sleeve stoppers are available for use as temporary closures for glassware joints, tubes, bottles, NMR tubes, ampules, and cannulation techniques in air-sensitive chemistry. To protect your valuable contents in the vessels or containers from the atmosphere, our range of septa provide

Polytetrafluoroethylene ( PTFE) is a synthetic fluoropolymer of tetrafluoroethylene and is a PFAS that has numerous applications. The commonly known brand name of PTFE-based composition is Teflon by Chemours, [3] a spin-off from DuPont, which originally discovered the compound in 1938. [3]

The C&G 60 mL precleaned VOA (volatile organic compound) vial is mainly used in research laboratories or in chemical industries. It is suitable for use with autosamplers, solid cap and liners for analysis. This L3 vial comes with a 24-414 white PTFE septa cap which offers tight sealing of sample. Compare this item.
