Three Layer Septa is made of preconditioned silicone rubber and is 3.81 mm (0.150 in.) thick. The average life of these septa is up to 100 injections with a 26s gauge needle. The maximum operating temperature is 200° C.
High Temperature Septa is made of preconditioned PTFE/silicone rubber and is 3.175 mm (0.125 in.) thick. The average life of these septa is up to 100 injections with a 26s gauge needle. The maximum operating temperature is 212° C.
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 (Agilent-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.
BTO is Bleed and Temperature Optimized for today's most demanding GC and GC/MS applications. Septa BTO is formulated to extend low-bleed and outstanding mechanical properties or premium GC septa to the highest-temperature applications. 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.
Low Bleed High Temperature Septa for operating temperatures up to 400° C.
