Additional Info:
The 9504S‑E‑WCV BASIK™ Screw‑Top Autosampler Vial is an economical 4 mL glass vial designed for laboratories that need larger sample volume capacity, easy filling, and clear sample labeling, without the cost of premium vial features. Manufactured from first hydrolytic, Class A borosilicate glass, this vial delivers reliable chemical durability suitable for routine chromatography workflows.
The 13‑425 (ND‑13) wide‑mouth opening allows convenient filling using pipettes or automated liquid handling systems, reducing handling errors during sample preparation. Integrated write‑on patches and graduations, applied using epoxy paint, provide a durable labeling surface that resists smearing when exposed to common laboratory solvents.
This vial offers strong value for budget‑minded laboratories and is compatible with autosamplers that require larger‑format vials, including certain legacy systems.
