Screw Top 8mm Black Plastic Closed Top Vial Cap w/ White PTFE/Red Silicone Septa, 100/Pk - CV1855
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.
Matching the right vial, cap, and septum configuration to your instrument and application ensures that sample containment never becomes a source of analytical uncertainty. Pre-assembled construction saves you the bench time of individual septum placement while delivering the lot-to-lot consistency your validated methods require. Standardize your sample containment system on components engineered for the dimensional precision and chemical inertness your chromatographic methods demand.
