Silicone Rubber / Ultraclean PTFE with Durometer of 45 Shore A, (hardness) and 3.0mm 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.
Clear lacquered Caps have score lines that will break open at 3.0 +/ 0.5 Bar, for safety.
