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.

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.

The Aijiren  Crimp vials are the standard vials for GC and HPLC. The crimp caps provide the tightest seal, reducing the chance of sample evaporation. The crimp vials and 20mm Aluminium crimp caps are economical, save your cost, and are easy to use with crimping tools.

The butyl septa on the PTFE surface can be used in the headspace sample bottle to evaluate the injection activity and the penetration efficiency of methyl bromide on the activated carbon. The septum can be used to seal the vial during liquid sample collection for unmodified benzene analysis using HPLC method

20mm Crimp neck with 6ml, 10ml, and 20ml hold-up volume. Available in flat or rounded bottom designs for accurate instrument compatibility. Pre-assembled 20 mm crimp caps with septa are ready to use with any headspace crimp top vials.

Aijiren Tech crimped top headspace vials have flat or round bottom styles, with clear or amber glass. Headspace seals can be used in pre-assembled caps with diaphragms or can be ordered separately. Pressure release, lined seal and magnetic lined seal are also optional.

Grey PTFE/Moulded Butyl Septa & Grey PTFE/Pharma-fix Butyl Septa for 20mm crimp vials, Size: 20*3mm, 100pcs/pk

Headspace vials can withstand the higher temperatures and internal pressures required for volatile gas analysis. With very low metal content, extractables and leachables, top headspace vials meet high standards to meet your regulatory requirements.

Headspace vials are available in clear or amber glass, with round or flat bases, with beveled or square crimp seals, or with screw threads. Headspace vials, septum and caps can be purchased separately in various quantities or together as convenience kits to suit your laboratory needs.

The 20mm Crimp Cap is often used with Headspace Vial. It is tightly sealed and suitable for long-term storage of samples. The cap with center hole can be cut by septa, which is convenient for automatic sampling needle sampling.

ND20 Crimp-top headspace refers to a specific type of headspace vial closure system used in gas chromatography (GC) for the analysis of volatile compounds.
ND20 headspace analysis can be performed using different techniques, such as static headspace, dynamic headspace, and purge and trap.
Each technique has its own advantages and is suitable for specific sample types and analyte properties.

Headspace Crimpe Vials are available in volumes from 6 mL to 20 mL. We offer Headspace Crimpe Vials with a flat top or a beveled top, and are available with either a flat bottom or a rounded bottom Headspace Crimpe Vials for your application.

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.

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.

Headspace vials are a kind of laboratory vials for top space analysis, with the features of high-temperature resistance and corrosion resistance.

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.

The Crimpe Top headspace vials produced by Aijiren are usually made of Aluminum. A special model is SBC201202, which uses double-sided Septa made of PTFE/Silicone and Crimp Top blue Magnetic Aluminum Cap with 8mm center hole.

Mainly used in gas chromatography analysis for headspace analysis.

Headspace vials have different capacity specifications, including 6ml, 10ml, 20ml, etc. Use a standard sample vial to ensure sufficient headspace. Usually, the reserved volume should be at least 50% of the sample volume.

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.

10 ml 20 ml headspace vial is a specialized type of vial used in gas chromatography (GC) analysis for the analysis of volatile compounds.
It is designed to hold a sample in the headspace, which is the gas phase above the liquid or solid sample.
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.

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.

Aijiren Tech crimp 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 are also optional.
