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 6ml, 10ml, 20ml versions with Screw and Crimp type.

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.

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.

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.

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.

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.

The material of Headspace Vials is low extractable Borosilicate glass with low expansion rate, high-temperature resistance, high strength, high hardness, high light transmittance and high chemical stability. Headspace Vials suitable for headspace analysis of volatile solids and gases.
