18mm septa use only the highest quality materials to ensure proper function, specifically for GC applications, ensuring the septum does not fall into the vial during sample injection.
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 suitable for headspace analysis of volatile solids and gases.
This is referring to the screw-thread caps (18 mm) and crimp caps (20 mm) for 10 mL headspace vials.We don’t just recommend screw cap headspace vial or crimp cap headspace vial by “feel” or price, running a little experiment to compare the performance of the two kind of headspace vial caps.
18mm Magnetic Metal Cap with Center Hole for more convenient for the automatic injection needle to perform sample injection.Generally speaking, the Septa in the 18mm Closures uses a double-sided compound of Silicone and PTFE Septa, which makes it difficult for Septa to react with reagents, and it can also protect impurities in the air from falling into the vial.
20mm 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.
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.

Headspace vials mainly used for headspace analysis for gas chromatography analysis. 20ml precision screw headspace vial, 18mm, round bottom, top space vial, strong adsorption.
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.
The Cap and Septas for 20mm Headspace Vial are essential components designed for secure sealing and reliable analysis in headspace sampling applications. The cap provides a tight closure, while the septa acts as a barrier, preventing contamination and maintaining sample integrity. This product is specifically designed to fit 20mm headspace vials, ensuring a seamless and effective sealing solution.
Headspace vials are common consumables generally used in gas phase experiments. 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.
Headspace vials are made of Aijiren’s borosilicate glass. The 18 mm screw-neck headspace vials with magnetic screw seals for CTC are new in the headspace market where crimped necks dominate.
Headspace vial is made of transparent or scarlet glass and is available on round or flat bases, crimp seals with bevel or square edge finishes, or thread finishes. Headspace viars, septaums, and caps can be purchased individually or collectively in different quantities as a convenient kit to meet the needs of the lab.
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.
Headspace vials are made of Aijiren’s borosilicate glass. You can choose from clear or amber colors. Screw-threaded headspace bottles have an average wall thickness of 1.25 millimeters, providing greater reliability as internal pressure increases. The screw headspace vials with 18 mm magnetic caps are suitable for autosamplers that use magnetic transport, while the crimp headspace vials can be used with aluminum caps.
Headspace vials are laboratory vials used for headspace analysis and are resistant to high temperatures and corrosion. Headspace vials are made of low extractable borosilicate glass with low expansion, high temperature resistance, high strength, high hardness, high light transmission and high chemical stability.
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.
Our Headspace Vial features a user-friendly design with a labeling area for easy sample identification and traceability. This enables efficient record-keeping and organization in your laboratory, ensuring accurate tracking and retrieval of crucial analytical information.
20ml,22.5ⅹ75mm, DM18 Material: USP1, Borosilicate Glass Box packaged tpo minimize sample bottle damage. Manufactured under strict quality, which ensures dimensional consistency from lot-to-lot Suitable for headspace analysis of volatile solids and gases. Store volatile samples to prevent sample evaporation High temperature resistance and corrosion resistance Mainly used in gas chromatography analysis for headspace analysis.
Our 18 mm 10 mL screw-top bottles are made from premium borosilicate glass to withstand the rigors of GC and headspace analysis, ensuring the long-term integrity and stability of your precious samples
Suitable for 11mm 2ml Crimp Neck Vials & 20mm Headspace GC Vials Caps Material: Aluminum Use Together with PTFE/Silicone Septa or Rubber Stopper Color: Metal Silver Vial Septa & Rubber Stopper and Crimpers are also Provided
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.
