Screw Cap 13mm Black Plastic Vial Cap w/ White PTFE/Red Silicone Septa, 100/Pk - CV1944
Ready-to-use Tisch CV1944 cap and septum assemblies reduce preparation time while maintaining the seal integrity demanded by automated HPLC and GC workflows. Matched cap and septum components undergo quality verification as a paired unit, providing lot-to-lot consistency that independent component sourcing cannot guarantee. Taken together, reliable component compatibility across the chromatography closure system supports reproducible analytical results from sample preparation through final data acquisition.
Matching the right vial, cap, and septum configuration to your instrument and application ensures that sample containment never becomes a source of analytical uncertainty. 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. Standardize your sample containment system on components engineered for the dimensional precision and chemical inertness your chromatographic methods demand.
