Screw Cap 13mm Black Plastic Vial Cap w/ Natural PTFE/Natural Silicone Septa, 100/Pk - CV1947
Pre-assembled cap and septum combinations from Tisch streamline sample preparation by delivering a matched closure system ready for immediate use. Assembled configuration arrives injection-ready, supporting rapid tray loading in time-sensitive pharmaceutical QC and environmental compliance workflows. On this basis, reliable component compatibility across the chromatography closure system supports reproducible analytical results from sample preparation through final data acquisition.
Whether running routine QC sequences or method development campaigns, your confidence in sample integrity begins with the vial system on the autosampler tray. 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.
