Reliabily against the carrier gas pressure in the inlet. Capable of being pierced and resealing time after time without pieces of the septa being deposited in the GC inlet system. Does not contaminate or bleed material into the chromatographic system.

• Silicone based septum faced on one side with a double layer of polyimide and PTFE
• The polyimide adheres to both the silicone and the PTFE, providing a better bond and enhanced durability
• The outer PTFE coating assures maximum inertness and helps minimise bleed
