1.5mL clear 9mm Screw Vial,

Each vial features a 30 μL conical (V-shaped) bottom that allows near-total sample recovery without the need for inserts. Made from Type I (Type 51) borosilicate glass, the vials provide excellent chemical resistance, low adsorption, and broad solvent compatibility. With a standard 1.5 mL volume and 9-425 screw-thread design (11.6 × 32 mm), they work reliably with HPLC, GC, and most mainstream autosampler systems.
