20mm Crimp Top Aluminum Caps for Headspace 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.

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.

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.

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.

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

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.

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.

1. Septa and slit septa are available. 2. The usually available cap color is silver, and other special colors can also be produced accordingly. 3. Easy to apply and easy to remove. 4. Aluminum sealing ring with pre-inserted septum is compatible with standard opening crimp top vials.

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.

Crimp Caps squeeze the septum between the rim of the glass vial and the crimped aluminum cap. This forms an excellent seal preventing evaporation. The crimp cap vial requires crimping tools to carry out the sealing process.

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.

The round-bottomed headspace vial distributes the internal pressure generated at high temperatures on the entire glass surface, and the beveled edge has a firm edge that can be pressed into the septum to achieve a more effective seal. The flat-bottomed sample bottle has a long neck and is suitable for use with headspace automatic sampling instruments

The Lab Use 20mm Crimp Headspace Vial is specifically designed for accurate and reliable analysis of headspace samples in laboratory settings. With its 20mm crimp neck, these vials ensure a secure and leak-proof seal during sample collection and analysis, maintaining sample integrity and preventing contamination.

20mm Butyl Rubber Stopper
Material: butyl rubber
Usage: bottle mouth sealing

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.

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

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.

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 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 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 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.

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’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.
