2020/8/4 · PTFE/silicone septa have excellent resealing characteristics and extensive chemical compatibility. Gray PTFE/Black butyl septa (Pharmafix type) It is a molded septum with a PTFE liner on the center surface, but does not extend to the edge of the septum.
PTFE is the most inert but its poor resealability makes it unsuitable for multiple injections or storage. For layered septa such as PTFE/silicone, the chemical resistance of the septa is that of PTFE until the septum is punctured. Once punctured, the silicone layer is exposed and able to react with the sample/solvent so the chemical []
