Description Septa are very important components of a syringe injection system Typically fabricated from elastomeric, self-sealing materials such as silicone rubber, neoprene, or fluoroelastomers Suitable to conveniently introducing the sample without causing the system to leak Improper septa decompose under the high-temperature conditions of capillary inlets causing baseline disruption and ghost peaks in a chromatogram These low cost, gray silicone rubber septa are designed for routine, isothermal use Inlet Temperature Range: 50°C to 200°C
