Headspace vials are a kind of laboratory vials for top space analysis, with the features of high-temperature resistance and corrosion resistance. A headspace vial is used in the process of top–gas chromatography. When detecting volatile or semi-volatile mixtures with high boiling points, we need to heat them to vaporize them at the top. In this process, since the liquid samples are at the bottom, the material in the top gas can be measured without touching the liquid in the sample vial. The material of Headspace Vials is low extractable Borosilicate glass with a low expansion rate, high-temperature resistance, high strength, high hardness, high light transmittance, and high chemical stability. Headspace Vials are suitable for headspace analysis of volatile solids and gases.

Aijiren 10mL certified screw and crimp style, clear or amber glass headspace vials. These 10ml Headspace GC Vials come in both flat- and round bottom styles for use in a wide variety of headspace instrument platforms.
