Features

Agilent septa are continually being improved to limit leaching, coring, sticking, push-through, hardness, and adsorption/absorption
During manufacture, Agilent septa undergo thermal and chemical conditioning to reduce siloxane bleed, which can occur when the septa material is stressed during heating, solvent interaction, or piercing by the autosampler needle
For highly sensitive samples, we recommend PTFE-lined (“sandwiched”) septa, because the PTFE layers act as a chemically resistant barrier

Specifications

Use the chart below to determine the right cap and septa combination, based on your application.

	PTFE/Silicone*	PTFE/Silicone/PTFE*	PTFE/Red Rubber
Temperature Range	-40 - 200°C	-40 - 200°C	-40 - 90°C
Use for multiple injections	Yes	Yes	No
Price	Economical	Most expensive	Very economical
Resistance to coring	Excellent	Excellent	None
Recommended for storage	Yes	Yes	No
Best for	Most common HPLC and GC analyses, not as resistant to coring as P/S/P	Superior performance for ultra analysis, repeat injections, internal standards	Chlorosilanes, more economical option for single injections

*Agilent silicone is peroxide cured, making it more inertand less likely to interact with samples
