Partial slit, only in the rubber leaves PTFE to form an evaporation barrier making this a good choice for volatile samples when an autosampler requires a pre-slit Septa.Y shaped partial slit allows for better "resealing" of rubber after initial injection.
Microsolv Technology Corporation Caps, Headspace, Crimp Top, with White Silicone Rubber / White PTFE, High Purity Septa, fitted in Bimetallic, Magnetic, Red Caps with 8mm center holes. For use with 20mm Crimp Top Headspace Vials. 100/PK.
High Purity Silicone Rubber / PTFE Septa with Durometer of 45 Shore A, (hardness) and 3.0mm thick with Ultra Low Bleed Rubber that is made with a proprietary process for ultra durability, purity and low extractables. Excellent choice for highly sensitive analyses. 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. Bimetallic caps are still magnetic but easier to crimp compared to all steel crimp caps.
