Rated 4.9/5 based on 537 customer reviews
Headspace vials are laboratory vials used for headspace analysis and are characterized by high temperature and corrosion resistance. Headspace analyzer vials are used in headspace gas chromatography analysis process. When testing 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 sample is located at the bottom, it is possible to measure the substances in the gas at the top without touching the liquid in the sample vial.
