Crimp Top 20mm Silver Aluminum Vial Cap, 100/Pk - CV2009
Available in open-center and closed-top configurations, Tisch chromatography caps accommodate diverse sealing requirements across HPLC and GC platforms. Open-center designs expose the septum for needle access, while closed-top variants provide a complete vapor barrier for storage applications where injection access is not required. Accordingly, standardized dimensional compliance across the full product line enables confident cross-platform deployment without instrument-specific qualification testing.
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. Consistent thread engagement and torque response across every cap in the pack give you the sealing predictability that automated capping systems and overnight runs demand. Ensure your analytical results reflect true sample composition rather than containment variability by selecting vials, caps, and septa built to consistent specifications.
