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.

The round-bottomed headspace vial distributes the internal pressure generated at high temperatures on the entire glass surface, and the beveled edge has a firm edge that can be pressed into the septum to achieve a more effective seal. The flat-bottomed sample bottle has a long neck and is suitable for use with headspace automatic sampling instruments

Aijiren focus on improving the safety and integrity of our Headspace vial. Aijiren provide innovative 20mL 20mm Crimp-Top Headspace Vial to ensure consistent productivity in all separation processes. These 20mL 20mm Crimp-Top Headspace Vial are the best choice for GC. 20mL 20mm Crimp-Top Headspace Vialmade of borosilicate glass.

The Crimp Top headspace vials are made of borosilicate hydrochloric acid. It has a transparent and amber color and can withstand a temperature range of -60 to 200 degrees Celsius. Generally speaking, the volume of the headspace vial is 10-20ml, and the characteristic is 22.5*46/75mm. The performance is acid resistance, alkali resistance and high temperature resistance. Packaging usually adopts inner packaging shrink plastic box.

The chromatographic direct range of 20mm crimped top-space sample vials and caps are available in 20ml amber and transparent colors, 10ml and 6ml with a variety of flat-bottom and round-bottom shapes, suitable for autosamplers of many brands on the market. Our 20mm crimp cap with silicone/PTFE Septa is compatible with all autosamplers.

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 20ml versions with Screw and Crimp type.

Metal caps offer the widest range of temperature tolerances and are very resistant to fracture from impact. Metal caps are great for gas chromatography applications. A metal closure is manufactured from either steel (coated with anti-corrosive coating of either chromeplate or tinplate) or aluminum.

PTFE-fused septa are suitable to overcome the degradation, which happens due to prolonged high temperatures, commonly observed in silicone rubber septa. The degradation results in baseline drift and additional peaks. It is generally fixed with the PTFE face towards the column packing.

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 20mm Crimp Top Caps produced by Aijiren have a diameter of 20mm and a center hole with a diameter of 9.5mm. The color is the silver color of aluminum itself, which is very modern and beautiful. The matched septa are all 20*3mm, and the double-sided synthetic septa ensures the sealing.

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.

Headspace vials have different capacity specifications, including 6ml, 10ml, 20ml, etc. Use a standard sample vial to ensure sufficient headspace. Usually, the reserved volume should be at least 50% of the sample volume.

The Lab Use 20mm Crimp Headspace Vial is specifically designed for accurate and reliable analysis of headspace samples in laboratory settings. With its 20mm crimp neck, these vials ensure a secure and leak-proof seal during sample collection and analysis, maintaining sample integrity and preventing contamination.

Torticollis headspace sample vial, 10mL or 20mL volume, flat-bottomed or round-bottomed 20mm crimp top vial cap to ensure consistent safety sealing.

Aijiren, as a supplier of chromatography consumables, provides headspace vials and sealing plugs. Aijiren s headspace vials and caps are carefully designed to prevent sample contamination and ensure accurate analysis. They come in various sizes and glass types. Optional crimping or threaded vials.

Headspace vials are laboratory vials for headspace analysis that are temperature and corrosion resistant. With very low metal content, extractables and leachables, they meet high standards to meet your regulatory requirements. These headspace vials have been specification certified for physical dimensions and autosampler compatibilit

Headspace vials are common consumables generally used in gas phase experiments. Headspace samples are typically prepared in vials containing sample, diluting solvent, matrix modifier, and headspace.

Aijiren provides one of the widest selections of Caps, Closures, and Lids available. Select from a wide variety of metal and phenolic, and polypropylene plastic bottle caps, vial lids, and other closures with an array of lining systems to fit your application and container. We also feature dispensing caps, hole caps, septa, tube caps and vial 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.
