Screw Top 13mm Clear Glass 4mL HPLC Autosampler Vials, 100/Pk - CV1950
Consistent wall thickness and flat-bottom geometry make Tisch CV1950 autosampler vials a dependable choice for high-throughput HPLC and GC sample processing. Borosilicate glass construction resists thermal shock during temperature-cycled storage and maintains chemical inertness across the full pH range of common mobile phases. 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. Flat-bottom stability and consistent wall thickness provide the predictable autosampler performance your high-throughput workflows depend on. Standardize your sample containment system on components engineered for the dimensional precision and chemical inertness your chromatographic methods demand.
