Screw Top 18mm Clear Glass 20mL Headspace GC Autosampler Vials w/ Round Bottom, 100/Pk SKU: CV1978

Screw Top 18mm Clear Glass 20mL Headspace GC Autosampler Vials w/ Round Bottom, 100/Pk - CV1978

Precision-manufactured borosilicate glass autosampler vials from Tisch deliver the dimensional consistency and chemical inertness demanded by modern HPLC and GC workflows. Manufactured under ISO 9001:2015 controls, each production lot meets the dimensional specifications required for cross-platform autosampler compatibility. Ultimately, consistent production quality eliminates the containment variables that compromise injection precision, supporting validated analytical performance at every step.

Your chromatographic results depend on the integrity of every seal, every vial surface, and every needle penetration — precision that starts with the consumables you select. Flat-bottom stability and consistent wall thickness provide the predictable autosampler performance your high-throughput workflows depend on. Invest in the injection-to-injection reproducibility your laboratory depends on by specifying consumables that match the quality standards of your analytical workflow.

• Petrochemical Analysis - Borosilicate thermal resistance accommodates elevated-temperature autosampler tray conditions without dimensional change.
• Forensic Toxicology Screening - Amber glass variants protect photosensitive analytes during extended autosampler queue storage intervals.
• Environmental Water Analysis - Clear glass construction enables visual sample inspection prior to chromatographic separation and detection.
• Clinical Research Samples - Inert glass surface prevents analyte adsorption that would compromise quantitative bioanalytical measurements.
• GC Autosampler Injection - Dimensional precision ensures reliable gripper engagement and consistent injection volumes across long sequences.
• HPLC Sample Analysis - Borosilicate glass vials provide chemical inertness for reversed-phase, normal-phase, and ion chromatography.
