Maximizing Sample Protection with Chemically Resistant FEP Vial Septa

  • 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.

  • Too easily overlooked, the vials, caps and septa that come in contact with the sample are a critical component of a successful analysis. Structurally, they must ensure a tight and secure fit in the analytical instrument. Compositionally, they must be able to withstand chemical and mechanical forces within a defined range.
