FAQ
Chromatography autosampler vial caps seal sample vials used in HPLC, UHPLC and GC workflows. They help prevent evaporation, contamination and sample loss while supporting consistent analytical performance.
Select a cap based on vial size, closure type, septa material and instrument compatibility. The Thermo Scientific, Fisherbrand and DWK brands/portfolios offer options for routine and advanced chromatography methods.
Silicone/PTFE septa are widely used because they provide chemical resistance, low extractables and reliable resealing performance during repeated injections.
Screw caps are commonly preferred for routine laboratory workflows because they are easy to apply, convenient to remove and provide dependable sealing performance.
High-quality vial caps help maintain sample integrity, reduce contamination risks and support reproducible chromatographic results, contributing to more reliable analytical data.
