Jun 13, 2022 · In the same way, some key features of pre-slit septa are that it can be Pre-slit I or +. It can be pre-slit PTFE or Silicone septa. Usually, its diameter measures 8mm to 22mm with a thickness of 1mm, 1.5mm, and 3mm. Most of which are made of either PTFE or silicone material. Again, pre-slit septa in vials aid in piercing easily.

The septum is provided with a thin 0.005” PTFE layer laminated to highly pure silicone, and slit through the center for easier needle penetration and to release the vacuum that forms when a large volume of sample is withdrawn from a vial.
Jul 1, 2016 · I was surprised to find that some helium leaked away for as much as 30 s after each injection, presumably because of a relatively slow-healing hole in the septum after each injection. Perhaps this effect was also related to the type of septum I used. I do recall that it was thought to be a high-quality silicone septum.
Silicone rubber septa. High quality, silicone rubber laminated to PTFE. Use when excellent resealing qualities are a must. Septum resists coring and is recommended when multiple injections are required. Preferred septa for use in liquid chromatography 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.
The VAP system is composed of three basic parts: port, septum, and catheter. The port (or port body) allows percutaneous access into a small hollow port reservoir through a compressed silicone septum. To maintain the functional integrity of the VAP, a noncoring Huber point needle must be used to puncture the silicone septum.
PTFE/Silicone Septa (T/S) has high-quality, low background/blank value, 100% synthetic pure silicone septa.
