Crimping headspace bottles are mostly used for liquids and powders that need to be sealed. The colors are mostly transparent colorless glass, amber glass, and silver open-hole aluminum cap.

In headspace gas chromatography analysis, headspace GC vial play an important role. The quality of headspace vial is related to the success or failure of the experimental results. Aijiren headspace vial are made of borosilicate glass, with safe and stable characteristics.

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.

The 20ml screw threaded headspace vial is used for the threaded vial (10ml + 20ml) and magnetic screw cap of CTC and TriPlus autosampler. It is easy to use and does not require any other tools. Samples can be transferred on site, without the need to transfer samples in the laboratory. The precise thread ensures the air tightness between the vial and the cap. Magnetic nut can be widely used in various SPME and headspace analysis. The round bottom vial is stronger, has higher pressure resistance when heating the sample vial, and is easier to slide into the heating hole.

Aijiren now offers a full range of GC headspace vial kits, including Crimp and Screw Top configurations. All sample vials are type 1 borosilicate glass, and the range is wide enough to cover all major manufacturers’ instruments, including Shimadzu, Aijiren, PE, CTC and Tekmar headspace instruments.

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

Aijiren’s 20ml Headspace Vial has a specification of 22.5*75mm. It has two colors, clear and amber. The glass type of precision screw headspace vial is 5.0 type, but 20ml clear precision screw headspace vial has a type with or without label area.

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

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.

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 size of 10ml Aluminum Crimp Caps with Headspace Vial produced by Aijiren is 22.5*46mm, and the glass types are divided into 5.0type and 7.0type. Since the headspace vial is suitable for gas chromatography, the tightness requirements of the vial are relatively high. Aijiren uses Aluminum Cap with Crimper and Decrimper to seal the vial.

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.

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 is a supplier of laboratory consumables, focusing on the production of 10mL 18mm Screw Thread Headspace Vial for GC. Aijiren has more than ten years of experience in making 10mL 18mm Screw Thread Headspace Vial and is a well-known brand among Chinese laboratory consumable suppliers. Aijiren strives to provide quality service to every customer.
