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.

Headspace vials are laboratory vials for headspace analysis that are temperature and corrosion resistant. With very low metal content, extractables and leachables, they meet high standards to meet your regulatory requirements. These headspace vials have been specification certified for physical dimensions and autosampler compatibilit

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.

Crimp Caps squeeze the septum between the rim of the glass vial and the crimped aluminum cap. This forms an excellent seal preventing evaporation. The crimp cap vial requires crimping tools to carry out the sealing process.

A headspace vial is used in the process of top – gas chromatography. The material of Headspace Vials is low extractable Borosilicate glass with low expansion rate, high-temperature resistance, high strength, high hardness, high light transmittance and high chemical stability. Headspace Vials suitable for headspace analysis of volatile solids and gases.

Aijiren provides one of the widest selections of Caps, Closures, and Lids available. Select from a wide variety of metal and phenolic, and polypropylene plastic bottle caps, vial lids, and other closures with an array of lining systems to fit your application and container. We also feature dispensing caps, hole caps, septa, tube caps and vial caps.

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 20mm Crimp Top Caps produced by Aijiren have a diameter of 20mm and a center hole with a diameter of 9.5mm. The color is the silver color of aluminum itself, which is very modern and beautiful. The matched septa are all 20*3mm, and the double-sided synthetic septa ensures the sealing.

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.

All 20mm Headspace Crimp Vials may appear to be created equal, but quality and performance make the difference when analyzing vital samples. Aijiren 20mm Headspace Crimp Vials are cleaned and packaged in a certified Class 10,000 clean room according to a designed process, developed to eliminate chromatographic errors associated with vials.

Headspace vials can withstand the higher temperatures and internal pressures required for volatile gas analysis. With very low metal content, extractables and leachables, they meet high standards to meet your regulatory requirements. These headspace vials have been specification certified for physical dimensions and autosampler compatibility.

Headspace GC is a sample preparation method for determining volatile compounds in solid and liquid samples. Headspace sample vial is generally used for gas phase experiments.

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.

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.

Head space vials analysis of gases present in head space sample vials,Laboratory bottles for head space analysis are called head space vials.
To get accurate results,We also have certain requirements for sample bottles and septa.
Head sample space are available with round bottom and flat bottom,as follows:
The round bottom is compatible with most automatic samplers,and the sample arm is convenient for carrying the sample vials from tray.
The flat bottom can achieve a high level of heating efficiency during manual head space injection and is suitable for certain types of instruments.
