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. Clear lacquered Caps have score lines that will break open at 3.0 +/ 0.5 Bar, for safety.
