Screw Top 8mm Black Plastic Vial Cap w/ Red PTFE/White Silicone/Red PTFE Septa, 100/Pk - CV1850
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. Ultimately, stringent manufacturing tolerances across vials, caps, and septa ensure that every component in the sample containment chain performs to the specifications modern analytical methods demand.
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. Eliminate sample containment as a source of analytical uncertainty by choosing chromatography consumables manufactured to the tolerances your instruments require.
