Screw Top 24mm Clear Glass 40mL EPA Autosampler Vials, 100/Pk - CV1973
Built from high-quality borosilicate glass, Tisch autosampler vials provide the optical clarity and thermal resistance required for rigorous analytical chromatography. Borosilicate glass construction resists thermal shock during temperature-cycled storage and maintains chemical inertness across the full pH range of common mobile phases. Taken together, standardized dimensional compliance across the full product line enables confident cross-platform deployment without instrument-specific qualification testing.
When your analytical methods require consistent sample containment from preparation through injection, every component in the closure system matters. Broad autosampler compatibility across Agilent, Waters, Shimadzu, Thermo Fisher, and PerkinElmer platforms means you can standardize on a single vial specification across your instrument fleet. Standardize your sample containment system on components engineered for the dimensional precision and chemical inertness your chromatographic methods demand.
