Headspace vials are specialized containers designed to hold samples for gas chromatography analysis, particularly when using headspace sampling techniques. The 20mm crimp-top variety refers to vials with a 20mm opening that is sealed with a crimped cap. These vials are available in various sizes, with 6ml, 10ml, and 20ml being the most common.

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.

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.

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.

The butyl rubber product is an off-white rubber-like solid with a density of 0.92g/cm3. It is odorless, insoluble in water, and soluble in hexane and chloroform. The product also has low air permeability, good airtightness, and good resistance. Ozone resistance, chemical resistance, electrical insulation, flexibility resistance, heat aging resistance, energy absorption and other characteristics.

The metal cover provides the widest temperature tolerance range and is very resistant to impact cracking. The metal cover is very suitable for gas chromatography applications. The metal cover is made of steel (chrome-plated or tinplate anti-corrosion coating) or aluminum.

Headspace borosilicate glass vials are a type of glass containers designed for storing and analyzing gas samples. They are commonly used in analytical chemistry and the pharmaceutical industry. The term “headspace” refers to the area above the liquid or solid sample in the vial, which contains the gas phase of the sample.
Borosilicate glass is chosen for these vials because it has low thermal expansion properties, making it resistant to thermal stress and thermal shock. This is important because headspace vials are often subjected to heating and cooling during the sampling process.

18mm septa use only the highest quality materials to ensure proper function, specifically for GC applications, ensuring the septum does not fall into the vial during sample injection.

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

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.

The optional capacity is 10ml 20ml and the specifications are 22.5 x 46mm, 22.5 x 75.5mm, providing both colorless and brown headspace vial. The 20ml GC Analysis Headspace Vial Series strictly controls the HPLC vial mouth to improve sealing performance. Precision molding bottlenecks increase the processing power of autosamplers.

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.

The Chromatography Direct range of 20mm Crimp Top Headspace Vials and Caps are available in 20ml Amber and Clear, 10ml and 6ml in a variety of flat and round bottom – suitable for CTC, Perkin Elmer and Aijiren autosamplers. Our 20mm Crimp Caps are Silicone/PTFE and compatibile with all autosamplers.

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.

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.

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

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.
