Premium Septa Marathon

The Marathon Premium Septum typically achieves 400 injections without failure, when used with a rounded-tip (Agilent-style) needle and autosampler or needle guide. The CenterGuide versions of Marathon are pre-pierced to channel the needle through the same spot with each injection, which helps eliminate the common type of coring that occurs on the first injection. The Marathon Premium Septum is also ideal for standard manual-injection GC and GC/MS and the Septa are packaged in glass vials for high purity.

• CenterGuide version for less coring
• Maximum temperature 350°C (except in the 17mm size)
• Thickness 3mm (except Shimadzu-style Septa)
