Screw Top 8mm Black Plastic Vial Cap w/ White PTFE/Red Silicone Septa, 100/Pk - CV1848
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. Accordingly, consistent production quality eliminates the containment variables that compromise injection precision, supporting validated analytical performance at every step.
When your analytical methods require consistent sample containment from preparation through injection, every component in the closure system matters. 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.
