Screw Top 8mm Black Plastic Vial Cap w/ Red PTFE/White Silicone Septa, 100/Pk - CV1849
Pre-assembled cap and septum combinations from Tisch streamline sample preparation by delivering a matched closure system ready for immediate use. Assembled configuration arrives injection-ready, supporting rapid tray loading in time-sensitive pharmaceutical QC and environmental compliance workflows. Reliable component compatibility across the chromatography closure system supports reproducible analytical results from sample preparation through final data acquisition.
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. Invest in the injection-to-injection reproducibility your laboratory depends on by specifying consumables that match the quality standards of your analytical workflow.
