Choose septa materials to meet your needs.
  • Gray Butyl Stoppers are an economical septum for lower temperature (125°C) or low-pressure applications.
  • 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. 
  • The Black Rubber septum is an economical choice for applications where reduced levels of vapor penetration are desired.
