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.

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 6ml, 10ml, 20ml versions with Screw and Crimp type.

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.

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

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.

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 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 chromatographic direct range of 20mm crimped top-space sample vials and caps are available in 20ml amber and transparent colors, 10ml and 6ml with a variety of flat-bottom and round-bottom shapes, suitable for autosamplers of many brands on the market. Our 20mm crimp cap with silicone/PTFE Septa is compatible with all autosamplers.

This table summarizes the full range of AIJIREN screw-cap headspace vials—available in 6mL, 10mL, and 20mL capacities, clear or amber glass, and with flat and round bottom options. Equipped with Type 5 or Type 7 septa and aluminum cap assemblies, they ensure leak-proof sampling. Suitable for high-throughput GC/HPLC and autosamplers.

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;

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.

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.

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 Crimp Top headspace vials are made of borosilicate hydrochloric acid. It has a transparent and amber color and can withstand a temperature range of -60 to 200 degrees Celsius. Generally speaking, the volume of the headspace vial is 10-20ml, and the characteristic is 22.5*46/75mm. The performance is acid resistance, alkali resistance and high temperature resistance. Packaging usually adopts inner packaging shrink plastic box.

These 20mm molded septa and grey butyl stoppers provide stable sealing performance for laboratory vials. Their 3mm thick structure ensures reliable needle penetration, low extractables and clean sample protection. Suitable for routine analysis, sample preparation and storage applications.

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.

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.

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.

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 available in clear or amber glass, with round or flat bases, with beveled or square crimp seals, or with screw threads. Headspace vials, septum and caps can be purchased separately in various quantities or together as convenience kits to suit your laboratory needs.

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.
