Screw Top 24mm Clear Glass 30mL EPA Autosampler Vials, 100/Pk - CV1971
Built from high-quality borosilicate glass, Tisch autosampler vials provide the optical clarity and thermal resistance required for rigorous analytical chromatography. Clear glass transmission supports visual sample assessment before injection, while amber variants protect photosensitive analytes from UV-induced degradation during storage. For this reason, 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.
Reliable injection-to-injection reproducibility in your chromatographic workflow starts with consumables engineered to maintain dimensional and chemical consistency across every lot. 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.
