Screw Cap 15mm Black Plastic Closed Top Vial Cap, 100/Pk - CV1958
Engineered for secure vial sealing, Tisch CV1958 chromatography caps maintain dimensional tolerances that ensure proper autosampler gripper alignment and removal. Chemical resistance of the polypropylene body ensures the cap contributes no leachable contaminants to the sealed sample environment during extended storage intervals. Because of this, consistent production quality eliminates the containment variables that compromise injection precision, supporting validated analytical performance at every step.
Matching the right vial, cap, and septum configuration to your instrument and application ensures that sample containment never becomes a source of analytical uncertainty. Chemical resistance and color-coded identification options let you organize your sample trays efficiently without introducing extractable contaminants into the sealed environment. Standardize your sample containment system on components engineered for the dimensional precision and chemical inertness your chromatographic methods demand.
