Thumbnail Filmstrip of White PTFE/ Silicone Septa, 20mm Press. Release Headspace Cap, 9.5mm Centre Hole, 100/Pk Images
White PTFE/ Silicone Septa, 20mm Press. Release Headspace Cap, 9.5mm Centre Hole, 100/Pk - CV2059
Pre-assembled construction in Tisch cap and septum pairs ensures proper septum centering and compression, eliminating the alignment inconsistencies of separate component assembly. Factory assembly under controlled conditions ensures each septum seats with uniform compression, delivering predictable reseal characteristics from the first through the final injection. 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. 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. Ensure your analytical results reflect true sample composition rather than containment variability by selecting vials, caps, and septa built to consistent specifications.
