Screw Cap 13mm Black Plastic Vial Cap w/ Red PTFE/White Silicone Septa, 100/Pk - CV1945
Pre-assembled cap and septum combinations from Tisch streamline sample preparation by delivering a matched closure system ready for immediate use. Factory assembly under controlled conditions ensures each septum seats with uniform compression, delivering predictable reseal characteristics from the first through the final injection. Because of this, consistent production quality eliminates the containment variables that compromise injection precision, supporting validated analytical performance at every step.
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.
