Screw Top 24mm Clear Glass 20mL EPA Autosampler Vials, 100/Pk - CV1969
Precision-manufactured borosilicate glass autosampler vials from Tisch deliver the dimensional consistency and chemical inertness demanded by modern HPLC and GC workflows. Flat-bottom geometry ensures stable positioning in autosampler trays, while precise outer diameter tolerances guarantee consistent gripper engagement and carousel indexing. 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. 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.
