Screw Top 9mm Black Plastic Vial Cap w/ Red PTFE/White Silicone Septa, 100/Pk - CV1821
Pre-assembled cap and septum combinations from Tisch streamline sample preparation by delivering a matched closure system ready for immediate use. Pre-installed septa eliminate bench time spent on manual septum placement and reduce the risk of off-center positioning that causes needle deflection or incomplete sealing. Working in concert, 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.
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. Invest in the injection-to-injection reproducibility your laboratory depends on by specifying consumables that match the quality standards of your analytical workflow.
