Long injection life, pre-pierced for minimal coring.
Maximum temperature 400 deg. C.
CRS Marathon ™ septum typically achieves 400 injections without failure, when used with a rounded-tip (Agilent-style) needle and autosampler or needle guide.
Marathon is ideal for standard manual-injection GC and GC/MS.
5 mm diameter, 3 mm thick. CenterGuide ™ design requires less force for initial penetration, for a smoother feel.
