Screw Cap 13mm Black Plastic Vial Cap, 100/Pk - CV1942
Engineered for secure vial sealing, Tisch CV1942 chromatography caps maintain dimensional tolerances that ensure proper autosampler gripper alignment and removal. Open-center designs expose the septum for needle access, while closed-top variants provide a complete vapor barrier for storage applications where injection access is not required. In combination, reliable component compatibility across the chromatography closure system supports reproducible analytical results from sample preparation through final data acquisition.
Reliable injection-to-injection reproducibility in your chromatographic workflow starts with consumables engineered to maintain dimensional and chemical consistency across every lot. Consistent thread engagement and torque response across every cap in the pack give you the sealing predictability that automated capping systems and overnight runs demand. Ensure your analytical results reflect true sample composition rather than containment variability by selecting vials, caps, and septa built to consistent specifications.
