20mm crimp-top headspace borosilicate glass vial is a specific type of vial used in headspace analysis, a technique commonly employed in gas chromatography (GC). These vials are designed to store and analyze samples for volatile compounds.
Headspace analysis involves the sampling and analysis of the vapor phase above a sample, typically done to analyze volatile compounds that can be released from solid or liquid samples.
The headspace vials are specifically designed to withstand the increased pressure and temperature conditions associated with this technique.It’s important to note that Headspace vials may also be available with other closure mechanisms, such as screw caps or magnetic caps.

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.

A headspace vial is used in the process of top – gas chromatography. 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.

Headspace vials, septum, and caps can be purchased in various quantities separately or together as convenience kits to fit your laboratory needs.

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.

The metal cover provides the widest temperature tolerance range and is very resistant to impact cracking. The metal cover is very suitable for gas chromatography applications. The metal cover is made of steel (chrome-plated or tinplate anti-corrosion coating) or aluminum.

Headspace vials can withstand the higher temperatures and internal pressures required for volatile gas analysis. With very low metal content, extractables and leachables, they meet high standards to meet your regulatory requirements. These headspace vials are specification-certified for physical dimensions and autosampler compatibility.

Aijiren Headspace Vials feature rounded shoulders and bottoms, allowing for even heating and safer operation at higher pressures. The newly designed top provides a tighter seal with your septa. Vials are manufactured from Type I borosilicate glass and accept 20 mm aluminum seals.

Aijiren Tech crimped top headspace vials have flat or round bottom styles, with clear or amber glass. Headspace seals can be used in pre-assembled caps with diaphragms or can be ordered separately. Pressure release, lined seal and magnetic lined seal are also optional.

Crafted with precision from high-quality borosilicate glass, our 18mm 20ml Screw Headspace Vial ensures excellent thermal stability and chemical resistance. The vial’s robust construction guarantees sample integrity, enabling accurate analysis of volatile compounds for reliable results.
