Magnetic Screw Top 18mm Silver Aluminum Vial Cap w/ Red PTFE/White Silicone Septa, 100/Pk - CV2027
Factory-paired with quality-verified septa, Tisch CV2027 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. Because of this, standardized dimensional compliance across the full product line enables confident cross-platform deployment without instrument-specific qualification testing.
Whether running routine QC sequences or method development campaigns, your confidence in sample integrity begins with the vial system on the autosampler tray. Pre-assembled construction saves you the bench time of individual septum placement while delivering the lot-to-lot consistency your validated methods require. Invest in the injection-to-injection reproducibility your laboratory depends on by specifying consumables that match the quality standards of your analytical workflow.
