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.

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 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.

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.

Our company provides a series of headspace vials to match different autosamplers. All headspace vials are standard vials: 20mm crimped headspace vials, suitable for Varian, Tekmar, Perkin Elmer and LEAP autosamplers. Material: Neutral borosilicate glass tube. Color: transparent/brown.

Aijiren’s 20ml crimp top headspace vials have two types of round bottom and flat bottom. Please check the instrument you are using before buying. Is the round bottom or flat bottom headspace vial suitable? Aijiren designed the 20ml crimp top headspace vials in order to be more Accurately use with your instrument. 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. You can refer to Aijiren’s product page to purchase the matching Hand Crimper/Decrimper.The caliber of the 20ml crimp top headspace is 20mm. Before buying, you need to check the specifications carefully to prevent it from being used after purchase.

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.

10ml 20ml laboratory bottles and vials are commonly used in scientific research and various laboratory applications.
Headspace vials are a specific type of laboratory vials designed for the analysis of volatile compounds in gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS).
It seems you are referring to two types of laboratory vials:
10ml and 20ml screw headspace vials made of either amber or clear glass, with aluminum caps.

Capacity: 10ml
Temperature: -60—200℃
Material: Borosilicate glass
Color: amber
Specification: 22.5*46mm
Packing: 100 pcs/pack, inner packing shrink plastic box

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

The 18mm screw thread 10ml gc vial produced by Aijiren has a specification of 22.5*46mm, and the glass is borosilicate glass, all of which are 5.0 type. The round bottom design prevents reagents from remaining on the bottom of the 18mm screw thread 10ml gc vial. Amber glass can protect samples sensitive to light.

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.

18mm combination seal: magnetic univerisal screw cap, silver, centre hole, ptfe/silicone or ptfe/butyl septa

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 is a manufacturer specializing in 6ml 20mm Crimp-Top Headspace Vial. Aijiren’s customers are located in more than 70 countries around the world. Aijiren has created the title of China’s well-known 6ml 20mm Crimp-Top Headspace Vial supplier with service and product quality.

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 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
