Crimp closure, N 11, alu., center hole, PTFE red/Silicone white/PTFE red, 1.0 mm

Both-sided PTFE laminated Silicone septa, so-called sandwich septa, are often used in high sensitive analysis and in research and development applications, since coring during penetration has been shown to be lowest here. Due to the high temperature resistance the material is ideal for usage in GC.
