Gray PTFE/Red Butyl 18x1.5mm Vial Septa w/ 18mm Magnetic Screw Cap (8mm Center Hole)- 100Pk - CV1995
Ready-to-use Tisch CV1995 cap and septum assemblies reduce preparation time while maintaining the seal integrity demanded by automated HPLC and GC workflows. Factory assembly under controlled conditions ensures each septum seats with uniform compression, delivering predictable reseal characteristics from the first through the final injection. Consistent production quality eliminates the containment variables that compromise injection precision, supporting validated analytical performance at every step.
Your chromatographic results depend on the integrity of every seal, every vial surface, and every needle penetration — precision that starts with the consumables you select. 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.
