China 20mm Headspace Vial Crimp Top Vial Supplier

Equipped with Silicone/PTFE Septa, and can also be used with slit septa. Usually the available cap color is silver, but other special colors can also be produced accordingly. There is a 9.5mm center hole in the center of the cap for automatic sample injection.

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.

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.

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 vial manufactured from Borosilicate glass by Aijiren. Headspace vial can be available in 6ml – 20ml. Clear or Amber can be choose. Crimp Thread Headspace Vials use a 1.25 mm average wall thickness, which offers more reliability when internal pressures build. Our Headspace Vials meet or exceed OEM standards.

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.

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.

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.

Headspace vials are a type of laboratory vials used for gas chromatography. They are designed to contain samples that will be analyzed using headspace gas chromatography, a technique used to analyze volatile compounds in solid or liquid samples. The vials are sealed with a septum cap, allowing the headspace above the sample to be analyzed without exposing the sample to the atmosphere. This technique is commonly used in pharmaceutical, environmental, and food analysis, among other fields.
Headspace vials, also known as gas chromatography (GC) vials or sample vials, are specialized containers used for the analysis of volatile compounds in gas chromatography. They are designed to store samples and create a headspace above the sample, which contains the volatile components to be analyzed.

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.

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 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.

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.

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 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 Tech headspace vials are manufactured to provide uniform glass thickness which insures even heat distribution for consistent sampling reliability. All Aijiren Tech headspace vials meet or exceed OEM instrument manufacturer’s specifications.Aijiren Tech vials are available in 20ml versions with Screw and Crimp type.

Teflon and silicone rubber or ultra-pure silicone are used as raw materials to ensure that the septa are non-toxic; to ensure excellent functions, it is particularly suitable for gas chromatography, and to ensure that the septum does not fall into the sample vial during the injection process;
