Silicone septum for lab applications

The Light Blue 12 x 32 mm Cap and PTFE/Silicone Septum forms a strong seal and hold the septum in place during piercing by mechanical means. The lab equipment is fairly easy to use and does not require any special tools for assembly. To ensure that your analytes are safe, only chemically inert components are used in its manufacturing.

Oct 28, 2021 · Cap/Septum has a natural Pre-slit Blue polytetrafluoroethylene (PTFE) and white silicone septa are convenient and minimize contamination from handling.Cap/Septum tested by head space GC to ensure proper curing of silicone polymer.2ml HPLC Vials caps and septa with most close space tolerance and caps and septa meet standards set

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.
