Microsolv Technology Corporation Caps, Headspace, Crimp Top, with Translucent Silicone Rubber / Natural PTFE, High Purity Septa, fitted in Aluminum, Silver Pressure Relief Caps with 8mm center holes. For use with 20mm Crimp Top Headspace Vials. 100/PK.
Silicone Rubber / PTFE Septa with Durometer of 45 Shore A, (hardness) and 3.0mm thick with Ultra Clean PTFE and Ultra Low Bleed Rubber that is made by a proprietary process for ultra high purity, low extractables and temperature durability. This Septa is good for highly sensitive analyses. No color has been added to this Septa. The lower Durometer means that this is a softer Septa and therefore better for easier penetrations by autosampler needles. Wide temperature range from -60⁰ to 200⁰C. Clear lacquered Caps have score lines that will break open at 3.0 +/ 0.5 Bar, for safety.

X Shape Pre-Slit provides a greater target area for needles and are easier to penetrate but do not reseal as well as single slit septa. Recommended for Waters Alliance & Acquity instruments. Soft-Guard™ Septa are easier to penetrate by autosampler needles, and re-seals better than other Caps on the market. This provides longer instrument up-time, fewer missed injections and more consistent data. Use for HPLC, GC, LCMS or GCMS.
