Screw Cap 15mm Black Closed Top Vial Cap w/ Natural PTFE/Natural Silicone Septa, 100pk - CV1964
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. 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. 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. Pre-assembled construction saves you the bench time of individual septum placement while delivering the lot-to-lot consistency your validated methods require. Eliminate sample containment as a source of analytical uncertainty by choosing chromatography consumables manufactured to the tolerances your instruments require.
