Premium septa are preconditioned and packed in glass jars. Premium septa offer long average injection lifetime with low bleed, at high inlet set point temperatures.

CenterGuide™ Septa for improved performance
• Center point guides the needle for easy penetration
• Reduce needle bending
• Precision molding assures accurate fit
• Available in selected sizes of our premium septa
Precison-molded septa have a recess on the injection side, to guide the syringe needle to the same point with every injection. The 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.

Upper Temperature Limit: Septa BTO®, Marathon™, and Advanced Green 3™ can be used at 400°C* and higher injector set point temperatures in most instruments. Slight sticking may occur in a new injection ports when holding septa above 300°C over periods of many days.

* For 17mm injectors the maximum is 330°C
