Magnetic Screw Top 18mm Silver Aluminum Vial Cap w/ White PTFE/Blue Transparent Silicone Septa - CV2028
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. As designed, standardized dimensional compliance across the full product line enables confident cross-platform deployment without instrument-specific qualification testing.
When your analytical methods require consistent sample containment from preparation through injection, every component in the closure system matters. Pre-assembled construction saves you the bench time of individual septum placement while delivering the lot-to-lot consistency your validated methods require. Ensure your analytical results reflect true sample composition rather than containment variability by selecting vials, caps, and septa built to consistent specifications.
