Red PTFE/White Silicone 11x1mm Vial Septa, 100/Pk - CV1879
Rated for a temperature range of -60°C to 200°C, Tisch PTFE/Silicone chromatography septa maintain seal integrity across ambient and elevated-temperature analytical methods. Flexible backing layer provides the mechanical compliance needed for clean needle penetration and self-sealing recovery, maintaining a gas-tight closure through repeated punctures. For this reason, stringent manufacturing tolerances across vials, caps, and septa ensure that every component in the sample containment chain performs to the specifications modern analytical methods demand.
Whether running routine QC sequences or method development campaigns, your confidence in sample integrity begins with the vial system on the autosampler tray. Precise dimensional cutting ensures uniform compression in the cap shell, giving you the consistent seal that prevents evaporation losses across extended autosampler queues. Ensure your analytical results reflect true sample composition rather than containment variability by selecting vials, caps, and septa built to consistent specifications.
