PTFE-faced silicone rubber septa are autoclavable, resist coring, and are recommended for use in all autosamplers using screw thread vials. Septa and liners can be laminated with PTFE on one or both sides to provide high chemical resistance and a nearly inert barrier between sample and septa material.

Best septa choice when temperatures are over 125°C. Natural PTFE/red silicone – ST3HT High temperature formulated seal with low bleed. Best septa choice when temperatures are up to 300°C. Blue silicone/red PTFE – ST144 Thin 1.4 mm seal with PTFE face. Resealing capability limited due to thinner silicone layer. Aluminum/white silicone – AS3

Features and benefits. Trajan septa undergo conditioning (thermal and chemical) to reduce siloxane bleed. Siloxane bleed can occur during heating, solvent interaction or piercing by the autosampler needle causing the material to become stressed. Septa liners are often laminated with a layer of high chemical resistance material such as PTFE or FEP.
