Agilent, 5183-2068, Vial, screw top, clear, write-on spot, certified, 2 mL, 1,000/pk. Vial size: 12 x 32 mm (12 mm cap)

Agilent certified 2 mL screw-top autosampler vials support routine sample handling in gas and liquid chromatography workflows. The clear glass vials measure 12 mm in diameter by 32 mm in height and use matching 12 mm screw caps. A write-on spot allows sample identification, while the clear walls permit visual inspection of fill level and sample appearance. The bulk package contains 1,000 certified vials suited to laboratories processing large numbers of samples for pharmaceutical quality control, contract analysis and research. The supplied item consists of glass vials; select compatible caps and septa separately to match the analytical method, autosampler and sample solvent. During preparation, avoid touching the vial rim or interior, use clean filling tools and confirm that cap torque and septum selection provide suitable sealing. For light-sensitive samples, consider amber vials rather than this clear-glass version. Check sampler rack and vial-height compatibility before use.
