Butyl Rubber Stopper for Wholesale

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

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 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. 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 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.

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.

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 can withstand the higher temperatures and internal pressures required for volatile gas analysis. The Color of headspace vials is divided into two kinds of brown and transparent, the brown vials can be protected from light, and the manufacturing process adopts the molding method, which has the characteristics of thick wall, high mechanical strength, and not easy to be broken.

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.

20mm crimp-top headspace borosilicate glass vial is a specific type of vial used in headspace analysis, a technique commonly employed in gas chromatography (GC). These vials are designed to store and analyze samples for volatile compounds.
Headspace analysis involves the sampling and analysis of the vapor phase above a sample, typically done to analyze volatile compounds that can be released from solid or liquid samples.
The headspace vials are specifically designed to withstand the increased pressure and temperature conditions associated with this technique.It’s important to note that Headspace vials may also be available with other closure mechanisms, such as screw caps or magnetic caps.

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.

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 20mm Caps with Septa are specifically designed for secure sealing and precise analysis of headspace samples in laboratory settings. These caps have a 20mm diameter, ensuring a tight and reliable fit on crimp headspace vials. The septa, made of high-quality materials, provide excellent sample integrity by preventing contamination and evaporation during storage and analysis.
