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.
Catalog number: S320-0060. Apply EPA Volatile Organic Analysis (VOA) soil methods when using Aijiren Tech™ Wide-Mouth Septa Jars. Available as clear or amber Type III soda-lime glass, jars are recommended for EPA Volatile Organic Analysis (VOA) soil methods. Open-top cap is equipped with a pierceable PTFE-faced silicone septum.
2. Using a gloved hand, unscrew the septum nut of the CAP injector, see Figure 2A. 3. The septum will either be sitting atop the injector port or will be adhered to the underside of the nut, see Figure 2B. Gently remove the septum with a pair of tweezers or another appropriate implement. 4. Select the correct septum for your lab operations. See
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.
