Crimp Top 20mm Silver Aluminum Vial Cap w/ Gray PTFE/Moulded Butyl Septa, 100/Pk - CV2021
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. Factory assembly under controlled conditions ensures each septum seats with uniform compression, delivering predictable reseal characteristics from the first through the final injection. Consistent production quality eliminates the containment variables that compromise injection precision, supporting validated analytical performance at every step.
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.
