Screw Top 8mm White Plastic Vial Cap w/ Red PTFE/White Silicone Septa, 100/Pk - CV1857
Ready-to-use Tisch CV1857 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. In combination, consistent production quality eliminates the containment variables that compromise injection precision, supporting validated analytical performance at every step.
From tray loading through the final injection in an overnight sequence, your sample containment system should perform without introducing the variables your method is designed to control. 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.
