Magnetic Crimp Top 20mm Blue Aluminum Vial Cap w/ Natural PTFE/Yellow Silicone Septa, 100/pk - CV2019
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. 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. Invest in the injection-to-injection reproducibility your laboratory depends on by specifying consumables that match the quality standards of your analytical workflow.
