Waters, 186000307C, LCGC Certified Clear Glass 12 x 32 mm Screw Neck Vial, with Cap and Preslit PTFE/Silicone Septum, 2 mL Volume, 100/pk

LCGC Certified Clear Glass 12 × 32 mm Screw Neck Vials are used for HPLC and LC-MS sample preparation and autosampler analysis. Each vial is made from clear glass, has a 2 mL capacity and uses a screw-neck closure. The package includes blue caps with preslit PTFE/silicone septa, so the vials arrive as complete assemblies for routine autosampler work. Waters LCGC certification includes HPLC cleanliness testing and controlled dimensional tolerances, helping reduce sample-container variability in chromatographic workflows. This configuration contains 100 vials, caps and septa. The preslit septum supports repeated autosampler needle penetration while maintaining closure integrity, and the standard 12 × 32 mm dimensions make the vials suitable for compatible chromatography autosamplers and sample-management systems.
