- Gray PTFE/Red Rubber Septa are an economical choice where a PTFE barrier is desired.
- PTFE/White Silicone PurePack Septa for general volatiles analysis.
- Gray PTFE/Molded Black Butyl Septa offer a more positive seal against loss of fixed gases.
- PTFE/Blue High Purity Silicone Septum reduces background from extractables or outgassing of volatile contaminants.
