Catalog Number - 95025-02

The 95025-02 MICROSOLV Headspace Septa are a made‑to‑order, fully laminated butyl/PTFE septa solution, designed for use with 20 mm crimp‑top headspace caps (sold separately).

These septa feature grey molded butyl rubber laminated with transparent PTFE on both sides, providing enhanced chemical resistance, reduced extractables, and strong elastic sealing, making them ideal for routine to moderately sensitive GC headspace applications.

Custom Order Item – Critical Notice
