SureSTART™ 6 mL Clear Glass Crimp Top Flat Bottom Headspace Vials, 1000/pack, Level 3 - FAQs

When should I use a headspace vial for my chromatography workflow?

Headspace vials are used when you want to analyze the gaseous phase of the sample rather than the liquid phase. These vials have a thicker glass wall to withstand higher temperature and internal pressure for the analysis of volatile gas in the vial’s headspace. Headspace vials with 20 mm crimp tops and 18 mm screw tops in sizes ranging from 6 mL to 20 mL are available in clear or amber glass. Choose from a round or flat base with a beveled or square edge finish.

Round base vials are compatible with most autosamplers and are more easily handled by robotic arms that lift the vial from the tray.

Flat base vials maximize heating efficiency in manual headspace sampling and are required for use in some instrument models.

The bevel edge on a vial lip provides additional sealing power for greater leak resistance under high pressure.
