make PTFE/silicone septa suitable for all types of chromatographic applications. A thin film of PTFE is laminated to the side of the septum that faces the sample to limit exposure of the elastomer to the solvent. PTFE/Silicone septa are ideal for use in most HPLC and GC applications where resealability and purity are critical. Pre-slit PTFE
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. Types of silicone rubber septa PTFE/silicone – ST1, ST15, ST18, ST2
PTFE/High Performance Rubber is a highly pure synthetic red rubber septum that provides a reduced background level for specific GC applications, employing sensitive detectors such as ECD or NPD. PTFE/Silicone Septa (T/S) has high-quality, low background/blank value, 100% synthetic pure silicone septa.
penetration even with thin bore GC needles. PTFE/Red Rubber septa are not recommended for multiple injections with long run times or retention of samples for further analysis after initial puncture. PTFE/Silicone Septa: (T/S) PTFE/Silicone is the most versatile septum material offered in various formulations
Mar 22, 2020 · Screw 8-425 (8mm, N8) HPLC Vial, Cap, Septa and Inserts. They are made with a 5.5 mm opening. These vials are designed to work on most autosamplers that use 12mm x 32 mm crimp style vials. They offer the convenience of screw thread vials for instruments that were originally designed for crimp top vials.

High Temperature GC Septa. High Temperature Septa is made of preconditioned PTFE/silicone rubber and is 3.175 mm (0.125 in) thick. The average life of these septa is up to 100 injections with a 26s gauge needle. The maximum operating temperature is 212° C.
Figure 3 - Typical mass chromatogram of volatile residue in hexane caused by PTFE/silicone septa: a) hexane extract of a piece of septum; b) vial septum was punctured once by a syringe to sample 1 μL hexane for GC analysis; c) hexane in the last vial was reanalyzed after 3 days; and d) analyzed immediately after 100 μL hexane was added from one vial to another (the septum was punctured 10

selecting septa. PTFE/red rubber septa are not recommended for multiple injections or for samples that need to be stored for further analysis. When applications require a longer time between injections or any type of standard additions, PTFE/silicone septa are always best. What force is required to penetrate the septum?
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.
Rubber septa. Used primarily for routine analysis in gas chromatography. Offers moderate ability to reseal and good chemical inertness. Not recommended for multiple injections or holding samples for further analysis. PTFE is protective layer that once broken exposes rubber to chemical attack. Types of rubber septa.
