Blue PTFE/White Silicone 11x1mm Vial Septa, 100/Pk - CV1881
Engineered with a chemically inert PTFE contact layer, Tisch CV1881 vial septa prevent sample interaction with the seal material during storage and injection. Pre-slit variants reduce needle coring by providing a defined penetration path, extending the effective puncture life and reducing particulate generation in the sample. 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.
From tray loading through the final injection in an overnight sequence, your sample containment system should perform without introducing the variables your method is designed to control. Precise dimensional cutting ensures uniform compression in the cap shell, giving you the consistent seal that prevents evaporation losses across extended autosampler queues. Standardize your sample containment system on components engineered for the dimensional precision and chemical inertness your chromatographic methods demand.
