Magnetic Screw Top 18mm Silver Aluminum Vial Cap w/ Blue PTFE/White Silicone Septa, 100/Pk - CV2026
Pre-assembled cap and septum combinations from Tisch streamline sample preparation by delivering a matched closure system ready for immediate use. Matched cap and septum components undergo quality verification as a paired unit, providing lot-to-lot consistency that independent component sourcing cannot guarantee. With this in mind, 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.
From tray loading through the final injection in an overnight sequence, your sample containment system should perform without introducing the variables your method is designed to control. Pre-assembled construction saves you the bench time of individual septum placement while delivering the lot-to-lot consistency your validated methods require. Ensure your analytical results reflect true sample composition rather than containment variability by selecting vials, caps, and septa built to consistent specifications.
