20mm 0.125" Natural PTFE/Silicone Lined Silver Seal
20mm Natural PTFE/Silicone Lined Silver Seal, 0.125"
High-performance septa for secure, inert sealing.
This 20mm silver crimp seal features a natural PTFE/Silicone liner (0.125" thickness) designed to provide a clean, chemically inert barrier for sensitive analytical applications. The PTFE layer offers exceptional chemical resistance, while the silicone backing ensures resealability and reliable sample integrity after multiple injections.
Ideal for use with headspace or general chromatography vials requiring 20mm crimp closures, these seals deliver consistent performance and compatibility with most autosamplers and crimping tools.
