10ml Screw Vial with Closures

The 10ml precision threaded headspace vial is used for the screw-top vial and magnetic screw cap of the CTC and TriPlus autosampler. It is convenient to use and does not require any additional tools such as cappers and decappers.

20ml Crimp Top Headspace Vial has a very good seal and can be used for volatile samples, but it needs to be used with 20mm Hand Crimper to seal the vials, and when opening the lid, it needs to be sealed with 20mm Hand Decrimper.

According to different materials, it can be divided into two types, one is domestic borosilicate, and the other is imported first-grade hydrolyzed glass to meet different levels of customer needs.
The optional capacity is 10ml 20ml, the specifications are: 22.5*46mm, 22.5*75mm, and two colorless and brown headspace vials are provided.

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.

The optional capacity of the headspace bottle is 10ml 20ml, the specifications are: 22.5 * 46mm, 22.5 * 75.5mm, and colorless and brown headspace vials are provided. The 20ml GC analysis headspace sample bottle series strictly control the HPLC sample bottle mouth to improve the sealing performance. The precise molding bottleneck improves the processing capacity of the autosampler.

10ml Crimp Headspace Vial is used in gas chromatography analysis experiments. For example, it is placed on an automatic sampler, and the sample is heated to vaporize the gas, and the automatic sample needle penetrates the septa into the vial to extract the gas for detection , So the tightness requirements for Crimp Headspace Vial are higher.

GC headspace vial, also known as a gas chromatography headspace vial, is a type of sample vial used in headspace analysis. Headspace analysis is a technique employed in gas chromatography (GC) to analyze volatile or semi-volatile compounds present in a sample.
The headspace vial is specifically designed to hold the sample and create a sealed environment for the analysis. It consists of a glass vial with a crimp or screw cap closure. The vial typically has a rounded or conical bottom to facilitate the removal of air from the headspace.

The 18mm Screw Headspace with caps with electromagnetic screw seals used for CTC is novel in the headspace vial market dominated by crimping necks. Especially for magnetic caps that are difficult to crimp, screw caps are a convenient choice. 18mm Screw Headspace with caps with aluminum skirt and magnetic center plate, it is easy to crimp and remove the cap. 18mm headspace vial with cap is preferred for the following instruments: Shimadzu.
How to choose whether to buy the Headspace Vial with round bottom or flat bottom? The round bottom is stronger, so it is more resistant to the high pressure in the sample Vial during heating. In addition, the vial is easier to slide into the heating block when transported by the magnet. When the vial must run in the instrument with a slight downward trend, a flat bottom may be required.Select the correct Headspace Vial at the bottom and use modern instruments to prepare the entire experiment with highly repeatable samples for accurate analysis.

The 10ml Crimp Top GC Vial produced by Aijiren is divided into two types: round bottom and flat bottom. Among them, Clear Glass will also be divided into 5.0type and 7.0type glass. It is worth mentioning that the 5.0type 10ml Crimp Top GC Vial is flat. The specification of 10ml Crimp Top GC Vial is 22.5*46mm.

Headspace vial mainly used in gas chromatography analysis for headspace analysis. The Headspace Vial is used to extract the volatile components from the complex sample mixture, separate them from the non-volatile components and inject them into the gas chromatography system for separation

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.

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
