Screw Top 24mm Amber Glass 20mL EPA Autosampler Vials, 100/Pk - CV1970
Consistent wall thickness and flat-bottom geometry make Tisch CV1970 autosampler vials a dependable choice for high-throughput HPLC and GC sample processing. Uniform wall thickness throughout the vial body delivers consistent sample visibility for visual inspection and supports reproducible light-path conditions in optical detection workflows. To this end, 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. 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. Ensure your analytical results reflect true sample composition rather than containment variability by selecting vials, caps, and septa built to consistent specifications.
