Catalog Number - 95025-09-5R

The 95025-09-5R BASIK Headspace Caps are a made‑to‑order, high‑purity configuration combining ultra‑clean silicone/PTFE septa (no added colorants) with magnetic bimetallic cap construction, providing exceptional chemical inertness, easier crimping than steel caps, and compatibility with automated headspace systems.

These caps are fitted in 20 mm blue bimetallic magnetic closures with an 8 mm center hole, offering enhanced sealing surface area, consistent needle access, and efficient handling for high‑throughput laboratory environments.

✅ Recommended for validated workflows requiring ultra‑clean septa with magnetic handling
