Virginal PTFE has the highest chemical resistance, however, no resealability at all. Furthermore the septa is very thin and due to the lack of any elastomeric layer the sealing process will not reach the level of tightness as with any other septa material. Therefore usage should be limited to uncritical HPLC analysis only.
