Magnetic Screw Top 18mm Silver Aluminum Vial Cap w/ Gray PTFE/Red Butyl Septa, 100/Pk - CV2029
Pre-assembled construction in Tisch cap and septum pairs ensures proper septum centering and compression, eliminating the alignment inconsistencies of separate component assembly. 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. Standardized dimensional compliance across the full product line enables confident cross-platform deployment without instrument-specific qualification testing.
Reliable injection-to-injection reproducibility in your chromatographic workflow starts with consumables engineered to maintain dimensional and chemical consistency across every lot. 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.
