Screw Top 8mm Black Plastic Vial Cap w/ Blue PTFE/White Silicone Septa, 100/Pk - CV1851
Pre-assembled construction in Tisch cap and septum pairs ensures proper septum centering and compression, eliminating the alignment inconsistencies of separate component assembly. Factory assembly under controlled conditions ensures each septum seats with uniform compression, delivering predictable reseal characteristics from the first through the final injection. Taken together, consistent production quality eliminates the containment variables that compromise injection precision, supporting validated analytical performance at every step.
Your chromatographic results depend on the integrity of every seal, every vial surface, and every needle penetration — precision that starts with the consumables you select. Factory-matched cap and septum assembly gives you guaranteed seal performance from the first puncture, eliminating the variability of manual septum installation across large sample sets. Ensure your analytical results reflect true sample composition rather than containment variability by selecting vials, caps, and septa built to consistent specifications.
