Oct 21, 2022 · Oct. 21st, 2022. The septa and vial caps are essential parts of HPLC vials. The vial cap serves as a barrier, keeping outside contaminants out of the vial and preserving the integrity of the sample. The septa, a seal between the injection needle and the vial composed of silicone, PTFE, or rubber, ensure accurate and exact sample injection.
Formulations offering highly consistent performance, lowest background/blank value, and good chemical compatibility, effective sealing/resealing and low penetration force make PTFE/silicone septa suitable for all types of chromatographic applications.

PTFE/Silicone Septa: (T/S) High quality, pure silicone is laminated to 0.005” thick PTFE to give a pure, highly inert septum with excellent resealing characteristics even after repeated punctures. PTFE/Silicone septa are the preferred product for use in most HPLC and GC applications where resealability and high purity are critical.
