Headspace Vial, 20 mL (CAT#: STEM-AL2-5218-ZJF)

The Headspace Vial is designed for sealed headspace sample preparation. The vial is made of glass and provides a closed container for liquid or gaseous samples. Its 20 mL nominal volume is matched to compatible headspace sampling systems. The cylindrical body dimensions support standardized handling in headspace workflows. A pure-aluminum sealing cap closes the vial after sample loading. A polymer septum provides a penetrable seal for automated or manual sampling. The closed-vial format supports equilibrium of volatile compounds above the sample prior to injection. It is suitable for routine headspace analysis requiring 20 mL glass sample containers.
