Septa, 11.5 mm, Long Life

Long injection life, pre-pierced for minimal coring. Maximum temperature 400°C. Long injection life septum typically achieves 400 injections without failure, when used with a rounded-tip (AS-style) needle and autosampler or needle guide. Ideal for standard manual-injection GC and GC/MS. 3 mm thick. CenterGuide™ design requires less force for initial penetration, for a smoother feel. Septum life may be enhanced in some applications by minimizing tearing and coring.
