The Screw Caps that are included with this kit are knurled on the sides for excellent gripping and comfort when applied to the vial. The silicone rubber / PTFE septa used were designed to provide the right amount of resistance to autosampler needles during the injection process so that they penetrate the vial properly without damaging the septa or the injection needle. Too much or too little resistance to the needles can damage the septa, compromise resealing, cause needle blockage from coring of the septa material and even damage your autosampler. These septa perform even when using a wide range of needles: fine, blunt, or even dull. Low sample or solvent evaporation performance even after multiple injections have been observed when using Aijiren caps.
