Our Mastelf Headspace Vials are manufactured from superior Type 1 hydrolytic class glass, featuring a thickened wall design to withstand high temperatures and internal pressure during headspace GC analysis.

Designed for accurate and reliable volatile compound analysis, our headspace vials ensure consistent performance in demanding laboratory conditions. The headspace GC method allows the analysis of volatile gases in samples by equilibrating a known volume of gas in the vial headspace, making vial integrity and sealing performance critical.

To ensure analytical stability, our manufacturing process includes special purging procedures to remove residual air before sealing, helping maintain consistent headspace conditions during transport, storage, and analysis.

We offer a full range of configurations, including:

Screw and crimp neck types
Flat and round bottom options
Clear and amber glass
Graduated and non-graduated designs
