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

Aijiren headspace vials have clear or amber glass, round or flat bases, crimp seals with beveled or square edges, or screw seals. Headspace vials, septa and caps can be purchased separately or together as a convenience kit to meet the needs of your laboratory.

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.

The screw headspace vial caps combine innovation with time-saving convenience, precise manufacturing tolerances, and a controllable manufacturing environment. The vial cap produced by this patented method truly combines the septum and the cap at the molecular level to avoid excessive evaporation and keep the sample vial properly sealed.

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.

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.

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.

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.

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.

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.
