A solid disk of PTFE offers superior chemical inertness against the most aggressive solvents. The thin membrane allows for easy penetration by most needles. PTFE septa are not resealable. They should be used with relatively short cycle times or single injection methods.

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.

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 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.

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 available as screw or crimp neck vials with flat or round bottoms, 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 is also optional.

Aijiren, as a supplier of chromatography consumables, provides headspace vials and sealing plugs. Aijiren s headspace vials and caps are carefully designed to prevent sample contamination and ensure accurate analysis. They come in various sizes and glass types. Optional crimping or threaded vials.

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.

Metal caps offer the widest range of temperature tolerances and are very resistant to fracture from impact. Metal caps are great for gas chromatography applications. A metal closure is manufactured from either steel (coated with anti-corrosive coating of either chromeplate or tinplate) or aluminum.

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.

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.

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.

volume: 10ml or 20ml, diameter: 20mm neck diameter

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.

Aijiren Headspace Vials feature rounded shoulders and bottoms, allowing for even heating and safer operation at higher pressures. The newly designed top provides a tighter seal with your septa. Vials are manufactured from Type I borosilicate glass and accept 20 mm aluminum seals.

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 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.

The 20mm septum is made of PTFE/silicone fusion, which has excellent inertness and can be used for multiple injections. The thickness is 3mm, and PTFE is about 0.08mm. The cap of the clamp-top empty bottle is made of metal aluminum

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.
