Screw Cap 13mm Black Plastic Closed Top Vial Cap, 100/Pk - CV1943
Polypropylene autosampler caps from Tisch deliver reliable closure integrity and consistent thread engagement across high-throughput sample preparation workflows. Available in multiple colors for visual sample identification, supporting color-coded batch organization and tray-position tracking in multi-method laboratory environments. Because of this, 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.
When your analytical methods require consistent sample containment from preparation through injection, every component in the closure system matters. 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. Standardize your sample containment system on components engineered for the dimensional precision and chemical inertness your chromatographic methods demand.
