Septa, 22mm, Translucent Silicone Rubber / Natural PTFE. Ultra Low Bleed. For use in 24mm Caps, sold separately. BASIK Brand. 1000/CS.
Additional Info:
Large‑format septa are used in applications requiring secure sealing, low bleed, and high purity, especially for storage, environmental testing, and volatile compound analysis.
The 97041‑09 septa are manufactured from high‑purity translucent silicone rubber with a natural (undyed) PTFE barrier, providing ultra‑low bleed characteristics and excellent chemical resistance. This makes them well suited for demanding applications such as EPA testing and long‑term sample storage.
With a temperature range of −60 °C to 200 °C, these septa maintain performance across a wide range of laboratory conditions. Designed for use in 24 mm (ND24) screw caps, they provide reliable sealing and compatibility with larger vial and bottle formats.
