CUSTOM ITEM: Septa, 22mm, Natural Silicone Rubber / White PTFE. Ultra Low Bleed. For use in 24mm Caps, sold separately. BASIK Brand. 1000/CS. BULK PRICING.
Additional Info:
Large‑format septa are used when secure sealing, low bleed, and high purity are required, particularly in demanding analytical and storage applications.
The 97041‑11 septa are manufactured from high‑purity natural silicone rubber with a white PTFE barrier, providing ultra‑low bleed performance and strong chemical resistance. This makes them well suited for sensitive workflows such as EPA testing, GC analysis, and long‑term sample storage where minimal background interference is critical.
With a thickness of 2.5 mm, these septa offer durable sealing and support repeated penetrations. The wide temperature range of −60 °C to 200 °C allows consistent performance across varied laboratory conditions.
Designed for use in screw caps with 24 mm (ND24) threads, these septa are supplied in polyethylene bags for clean handling and storage.
