Jan 29, 2021 · Treating butyl septa with NaOH reduced trace-gas release, but contamination was still substantial, with H 2 and CO mixing ratios in air samples increasing by a factor of 3 and 10 after 30 d of storage in conventional 12 mL Exetainers.
On the other hand, butyl rubber–PTFE septa are mechanically hard and more resistant to the absorption of the constituents of a sample, and it is stable up to 130°C (12, 14). Kolb et al. showed that in using silicone–PTFE rubber septa, 69% of acetone and 89% of dichloromethane were lost, while in butyl–PTFE rubber septa, the losses were

A specially moulded seal with a PTFE insert. Sealing surface of Butyl and PTFE affects a more positive seal than non-PTFE-faced septa. Ideal choice for temperatures below 125°C. Good sealing characteristics, excellent resistance to most solvents with reduced coring and high puncture tolerance.
Products. Septa. By definition, a rubber septum consists of a disk of rubber or similar material used to seal a vial or other device. It is installed along the inside of a cap, which is typically made of metal or plastic. A syringe needle pierces the rubber septum for the purpose of injection and, on withdrawal, the elasticity of the septum
Black rubber septa Black Rubber septa are molded from a higher density rubber compound compared to the standard red rubber. This septum has characteristics similar to the gray butyl stopper. The Black rubber septum is an economical choice for applications where reduced levels of vapor penetration are desired. Temperature stability chart Min

Septa. Septa are available in a variety of materials and thicknesses. PTFE Natural Rubber are moderately priced seals for GC and HPLC with good chemical properties. They are ideal for multiple injections due to high resealability, but not as easy to penetrate as PTFE/RR. PTFE/High Performance Rubber is a highly pure synthetic red rubber septum
