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.
A pre-slit PTFE/silicone septum may be the ideal choice for improving autosampler reproducibility. PTFE/red rubber: PTFE/red rubber septa are a popular and affordable option for standard gas chromatography uses. These septa provide moderate resealing capabilities and high chemical inertness.
Septa.

warmed to room temperature. To prevent breakage, turn the stopcock as the apparatus warms. An all glass stopcock is an option. However, solvents used for our reagents will slowly dissolve most stopcock greases. When this is a concern, a PTFE-clad stopcock may be substituted. Given the expense and the limited lifetime of a PTFE-clad glass plug, it
The thermal stability of FFKM is much higher than that of fluorocarbon elastomers that contain hydrogen in their structure. For example, the long-term maximum use temperature of FFKM is 315°C, while the long-term maximum use temperature of fluoroelastomers (FKM) is 215°C. Figure 1. Operating temperature range of fluoroelastomers [1]
