Screw Top 8mm Pre-Slit Black Plastic Vial Cap w/ White PTFE/Red Silicone Septa, 100/Pk - CV1852
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. 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.
When your analytical methods require consistent sample containment from preparation through injection, every component in the closure system matters. 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.
