Caps, Headspace, Crimp Top, with Translucent Silicone Rubber / Natural PTFE, High Purity Septa, fitted in Bimetallic, Magnetic, Blue Caps with 8mm center holes. For use with 20mm Crimp Top Headspace vials. BASIK Brand. 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.
Bimetallic caps are still magnetic but easier to crimp compared to all steel crimp caps.
