Septa are designed to reliably seal against the carrier gas pressure in the inlet
Septa GP combines significantly longer injection life, low bleed, and low injection port adhesion. Intended for low temperature applications, they are blister packed to prevent absorption from the environment.
Septa GP offer good durability, resealing, and tear resistance properties, along with excellent solvent resistance.
All septa should be capable of being pierced and resealed time after time, without pieces of the septa being deposited in the GC inlet system. It is essential that the septa does not contaminate or bleed material into the chromatographic system.
