Screw Top 9mm Black Plastic Vial Cap, 100/Pk - CV1808
Polypropylene autosampler caps from Tisch deliver reliable closure integrity and consistent thread engagement across high-throughput sample preparation workflows. 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. Standardized dimensional compliance across the full product line enables confident cross-platform deployment without instrument-specific qualification testing.
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. Eliminate sample containment as a source of analytical uncertainty by choosing chromatography consumables manufactured to the tolerances your instruments require.
