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.

Headspace vials have to withstand high internal pressure. Therefore, the wall thickness of headspace vials is higher compared to standard Headspace Vials, ND20, 20 mL, 22x75 mm, Long Neck, Flat Bottom, DIN Finish | DWK Life Sciences

Fine-Threaded vials ND18: Due to the fine thread the vials are sealed gas tight. They are therefore suitable for headspace and solid phase microextraction analyzes. Roll edge and headspace vials ND20: For headspace analyzes, the sample vials must withstand a high internal pressure and therefore have a thicker wall thickness.
