Screw Top 9mm Black Plastic Vial Cap w/ Red PTFE/White Silicone Septa, 100/Pk - CV1820
Combining a precision-molded cap with a pre-installed PTFE-lined septum, Tisch pre-assembled closures provide consistent seal performance from the first needle puncture. Matched cap and septum components undergo quality verification as a paired unit, providing lot-to-lot consistency that independent component sourcing cannot guarantee. 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.
