High-quality, pure silicone is laminated to 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. Works well for applications where ease of needle penetration is important.
