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 -60° to 200°C.

Bimetallic caps are still magnetic but easier to crimp compared to all steel crimp caps.
