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.

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.

Headspace borosilicate glass vials are specialized containers used in the pharmaceutical and scientific industries for the storage and analysis of gases or volatile substances. These vials are made from borosilicate glass, which is known for its exceptional thermal resistance and chemical inertness.
The term “headspace” refers to the space above the liquid or sample inside the vial, which contains the vapor or gas phase of the substance. In applications such as gas chromatography, where the analysis of volatile compounds is required, the headspace technique is commonly employed.

Suitable for 11mm 2ml Crimp Neck Vials & 20mm Headspace GC Vials
Caps Material: Aluminum
Use Together with PTFE/Silicone Septa or Rubber Stopper
Color: Metal Silver
Vial Septa & Rubber Stopper and Crimpers are also Provided

The 20mm septum is made of PTFE/silicone fusion, which has excellent inertness and can be used for multiple injections. The thickness is 3mm, and PTFE is about 0.08mm. The cap of the clamp-top empty bottle is made of metal aluminum

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.

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.

These 20mm molded septa and grey butyl stoppers provide stable sealing performance for laboratory vials. Their 3mm thick structure ensures reliable needle penetration, low extractables and clean sample protection. Suitable for routine analysis, sample preparation and storage applications.

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.

Headspace Vials Available from Aijiren Tech. Headspace vials are available in volumes from 6 mL to 20 mL in clear glass. Headspace vials are available in clear or amber glass with a round or flat base, a crimp seal with a beveled or square edge finish, or 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.

Aijiren Tech headspace vials are manufactured to provide uniform glass thickness which insures even heat distribution for consistent sampling reliability. All Aijiren Tech headspace vials meet or exceed OEM instrument manufacturer’s specifications.Aijiren Tech vials are available in 10ml, 20ml versions with Screw type.

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.

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.
