Screw Cap 13mm Pre-Slit Black Plastic Vial Cap w/ White PTFE/Red Silicone Septa, 100/Pk - CV1949
Factory-paired with quality-verified septa, Tisch CV1949 cap assemblies eliminate the variability of manual septum placement in high-volume chromatography labs. Matched cap and septum components undergo quality verification as a paired unit, providing lot-to-lot consistency that independent component sourcing cannot guarantee. As a result, 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. 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.
