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.

More convenient, consistent, and safer sealing process compared to crimping (better reproducibility). No risk of inaccurate or inconsistent crimping results. Due to thinner septa suitable for SPME as well as for Headspace. Often used on CTC Combi PAL and identically constructed autosamplers as well as on Perkin Elmer instruments.
Aijiren supply ND18 screw headspace vial in wholesale price, welcome to inquiry. You can also find Aijiren by those channel.

Headspace vials are available in clear or amber glass with a round or flat base, with a screw-thread finish. Headspace vials, septum, and caps can be purchased in various quantities separately or together as convenience kits to fit your laboratory needs.

The 20ml headspace vial is very popular in gas chromatography because of its large capacity, because it allows the vaporized gas in the sample to float on the upper layer and completely separate from the liquid, which is convenient for the autosampler to extract the gas to be detected. The Screw Cap has a center hole to ensure the convenience of the automatic injection needle in and out.

Headspace vials are laboratory vials used for headspace analysis and are characterized by high temperature and corrosion resistance.

Headspace vials are used in headspace gas chromatography processes. They are suitable for headspace analysis of volatile solids and gases.

The material of the headspace sample vials is low-extraction borosilicate glass, which is characterized by low expansion, high temperature resistance, high strength, high hardness, high light transmission and high chemical stability. Headspace vials are suitable for headspace analysis of volatile solids and gases. 20mm crimp headspace vial is widely used in Headspace and GC, GCMS application.

With the use of headspace vials, the whole experiment can be prepared for analysis in an efficient and accurate way. The essence of this experiment is that the volatile sample is heated and vaporized to form a gas in the top space of the headspace vial and then diffuses. Finally, the gas in the vial enters the gas phase detection.

18mm Screw Top Headspace Vial optional capacity is 10ml 20ml, the specifications are: 22.5*46mm, 22.5*75.5mm, providing headspace vials in both colorless and brown colors. The 20ml GC analysis headspace vials series strictly controls the HPLC vials mouth to improve the sealing performance. The precision molding bottleneck improves the processing capacity of the autosampler.

Headspace vials and closures must form a tight seal for accurate analysis with reproducible results. Available in clear or amber Type I borosilicate glass with crimp or screw thread finishes. The vials are used to heat the sample until the concentration of the liquid and gas phases are in equilibrium. A sample is then taken from the gas phase (headspace) for analysis.
