Flare cap, N 11, aluminum, hole, PTFE red/silicone white/PTFE red, 1.0 mm

Description

Silicone septa coated on both sides with PTFE, also known as sandwich septa, are used for highly sensitive analyses and in research and development, as it has been proven that particle formation during penetration is lowest here. Due to its high temperature resistance, the material is often used in GC.
