Screw Top 18mm Amber Glass 20mL Headspace GC Autosampler Vials w/ Round Bottom, 100/Pk SKU: CV1980

Screw Top 18mm Amber Glass 20mL Headspace GC Autosampler Vials w/ Round Bottom, 100/Pk - CV1980

Consistent wall thickness and flat-bottom geometry make Tisch CV1980 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. Working in concert, consistent production quality eliminates the containment variables that compromise injection precision, supporting validated analytical performance at every step.

From tray loading through the final injection in an overnight sequence, your sample containment system should perform without introducing the variables your method is designed to control. Certified dimensional tolerances and high-clarity borosilicate construction give you a sample vessel that performs identically whether processing ten samples or ten thousand. Standardize your sample containment system on components engineered for the dimensional precision and chemical inertness your chromatographic methods demand.
