PTFE Septa A solid disk of 0.010” thick PTFE offers superior chemical inertness against the most aggressive solvents. The thin membrane allows for easy penetration by most needles. PTFE septa are not resealable. They should be used with relatively short cycle times or single injection methods.

Jun 12, 2023 · Pre-slit PTFE/Silicone Septa are commonly used in high-throughput analysis due to their ease of use and reliable sealing properties. The pre-slit design allows for efficient and rapid needle penetration, making them suitable for applications requiring fast and repetitive injections.

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]

Jul 31, 2020 · Needle Gauge: A bigger needle gauge can need more force to get through non-pre-slit septa, which could cause damage to the septa or sample contamination. A pre-slit septum might be the best choice in this situation. Injection Frequency: A pre-slit septa may be more appropriate for applications requiring repeated injections since it can lessen
