Tips for Handling Septa<\/h2>\n\n\n\n

All septa, regardless of composition, puncturability, or resistance to thermal degradation will fail if they are mishandled. Overtightening a septum nut invariably will reduce septum lifetime by increasing coring\/splitting. All septa contain volatile materials (e.g., phthalates) that are released when the septum is heated (septum bleed). Because most GCs are equipped with a septum purge, septum bleed generally will disappear within 30 minutes after installing a new septum and exposing it to normal injector temperatures. All Restek septa are preconditioned and are ready to use without delay\u2014order your Restek septa today at www.restek.com\/septa<\/a><\/p>\n<\/div>\n<\/div>\n\n\n\n
