2 mL Screw Top Vials & Caps

2 mL screw top vials & caps are widely used for sample containment in HPLC and GC workflows, providing a practical option for routine analysis, sample storage and sample preparation prior to analysis. The range typically includes 2 mL glass vials in clear or amber glass, with options such as write-on spots for easier sample identification. These HPLC and GC vials support a wide range of chromatography applications, including pharmaceutical, environmental, forensic and toxicology, food and beverage, and life science testing.

Designed for compatibility with standard chromatography autosamplers, 2 mL HPLC vials can be paired with 9 mm screw caps to create a secure, consistent seal that helps protect sample integrity and reduce evaporation. Screw caps are available with a choice of septa materials to suit different sample types and analytical requirements, while the 9 mm screw cap format supports quick application and removal during busy laboratory workflows.
