Screw Top 8mm White Plastic Vial Cap w/ White PTFE/Red Silicone Septa, 100/Pk - CV1856
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. By design, 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. Invest in the injection-to-injection reproducibility your laboratory depends on by specifying consumables that match the quality standards of your analytical workflow.
