SIMILAR TO 95025-09-2SHigh 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 -60⁰ to 200⁰C. Bimetallic caps are still magnetic but easier to crimp compared to all steel crimp caps.
Perkin Elmer US LLC Zero Dilution Glass Inner Liner for Capillary and PSS Injectors
Inlet liners for split injection have mixing chambers with tortuous flow paths to allow full vaporization of the sample. Deactivating the surface of these liners prevents active compounds from degrading. Packing the liner with wool will trap non-volatile residue and prevent column contamination when analyzing dirty samples. Inlet liners for splitless injection are generally designed as straight tubes, although new designs such as the gooseneck will help contain the sample in the injector. Packing these liners with wool will also help trap non-volatile residue and prevent column contamination. Compatible with the 480, 580, 680 and older Clarus GC models. Not compatible with Clarus 590/690 capillary injector.
