20mm crimp-top headspace vials for gas chromatography instrument

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.

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.

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.

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.

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 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.

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.

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.

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.

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.

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.
