Caps, Headspace, Crimp Top, with Transparent Blue Silicone Rubber / Transparent PTFE Septa, fitted in Bimetallic, Magnetic, Red Caps with 8mm center holes. For use with 20mm Crimp Top Headspace Vials. MicroSolv Brand. 100/PK.

Additional Info:

Silicone Rubber / Ultraclean PTFE with Durometer of 45 Shore A, (hardness) and 3.2mm thick. Completely laminated with PTFE on both sides of the Septa which is good for 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.
