Gas chromatography headspace Borosilicate Glass vials with PTFE, Silicone, Pharma-Fix Butyl Septa

Headspace vials mainly used for headspace analysis for gas chromatography analysis. 20ml precision screw headspace vial, 18mm, round bottom, top space vial, strong adsorption.

Our Headspace Vial features a user-friendly design with a labeling area for easy sample identification and traceability. This enables efficient record-keeping and organization in your laboratory, ensuring accurate tracking and retrieval of crucial analytical information.

The round-bottomed headspace vial distributes the internal pressure generated at high temperatures on the entire glass surface, and the beveled edge has a firm edge that can be pressed into the septum to achieve a more effective seal. The flat-bottomed sample bottle has a long neck and is suitable for use with headspace automatic sampling instruments

20mm crimp-top headspace vials are a type of laboratory vials commonly used in gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) applications.
These vials are specifically designed for the analysis of volatile compounds in samples.
Headspace analysis is used when analyzing volatile or semi-volatile compounds that can be released from a solid or liquid sample into the gas phase.
This technique is particularly useful for samples that would be difficult to directly inject into a GC system or when analyzing volatile compounds in complex matrices.

10ml 20ml Headspace GC vials are a type of sample vial used in gas chromatography (GC) analysis.
They are specifically designed for the analysis of volatile and semi-volatile compounds present in a sample.
Headspace analysis involves the extraction of volatile compounds from a solid or liquid sample into the gas phase for injection into a GC instrument.
20mm aluminum caps and septa are commonly used in chromatography applications, including gas chromatography (GC) and high-performance liquid chromatography (HPLC). They are used to seal sample vials and ensure a gas-tight or liquid-tight seal.

The chromatographic direct range of 20mm crimped top-space sample vials and caps are available in 20ml amber and transparent colors, 10ml and 6ml with a variety of flat-bottom and round-bottom shapes, suitable for autosamplers of many brands on the market. Our 20mm crimp cap with silicone/PTFE Septa is compatible with all autosamplers.

Crafted with precision from high-quality borosilicate glass, our 18mm 20ml Screw Headspace Vial ensures excellent thermal stability and chemical resistance. The vial’s robust construction guarantees sample integrity, enabling accurate analysis of volatile compounds for reliable results.

The material of the headspace sample vials is low-extraction borosilicate glass, which is characterized by low expansion, high temperature resistance, high strength, high hardness, high light transmission and high chemical stability. Headspace vials are suitable for headspace analysis of volatile solids and gases. 20mm crimp headspace vial is widely used in Headspace and GC, GCMS application.

Aijiren’s Headspace Caps often use metal material aluminum, which is soft and convenient for Hand Crimper and Decrimper for sealing. Not only that, the Septa produced by Aijiren is also made of high-quality silicone and ptfe, and is pressed with an exclusive process. This kind of septa is not easy to deform, break, and fall off, and it can also ensure the tightness of the vial.

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.

Headspace vials are common consumables generally used in gas phase experiments. Headspace samples are usually prepared in vials containing sample, dilution solvent, matrix modifier and headspace.

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 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.

A headspace vial is used in the process of top – gas chromatography. When detecting volatile or semi-volatile mixtures with high boiling points, we need to heat them to vaporize them at the top. In this process, since the liquid samples are at the bottom, the material in the top gas can be measured without touching the liquid in the sample vial.

Aijiren Tech crimps top headspace vials are available in a flat or round bottom style, with clear or amber glass. Headspace closures are available in pre-assembled caps with septums or can be ordered individually. Pressure release, seal with lining, and seal with magnetic lining is also optional.

Aijiren Tech Headspace Vials are available as screw or crimp neck vials with flat or round bottoms, with clear or amber glass. Headspace closures are available in pre-assembled caps with septums or can be ordered individually. Pressure release, seal with lining, and seal with magnetic lining is also optional.

18mm Magnetic Metal Cap with Center Hole for more convenient for the automatic injection needle to perform sample injection.Generally speaking, the Septa in the 18mm Closures uses a double-sided compound of Silicone and PTFE Septa, which makes it difficult for Septa to react with reagents, and it can also protect impurities in the air from falling into the vial.

PTFE-fused septa are suitable to overcome the degradation, which happens due to prolonged high temperatures, commonly observed in silicone rubber septa. The degradation results in baseline drift and additional peaks. It is generally fixed with the PTFE face towards the column packing.
