18mm 20ml Screw Headspace Vial for GC

If your sample is sensitive to light, use amber vials. If you need to view a color change then a clear Screw Top HPLC Chromatography Vials are the best choice. The Screw Top Headspace Vials are manufactured from Type I borosilicate glass.
Aijiren as a leading manufacturer in China, supply high quality Screw Top Headspace Vials, caps, septa and syringe filters. The consistancy of our products between each batch is very good, you can be assure with our quality.

The 18mm Screw Headspace Vials are designed specifically for headspace analysis, a technique used to analyze volatile compounds in a sample. The vials accommodate the headspace sampling process, which involves collecting and analyzing the gas phase above a sample, providing accurate and representative results

The optional capacity is 10ml 20ml and the specifications are 22.5 x 46mm, 22.5 x 75.5mm, providing both colorless and brown headspace vial. The 20ml GC Analysis Headspace Vial Series strictly controls the HPLC vial mouth to improve sealing performance. Precision molding bottlenecks increase the processing power of autosamplers.

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.

To seal the vial, the screw cap is securely threaded onto the vial neck. The threading mechanism ensures a tight and reliable seal, preventing any leakage or contamination of the sample. The screw top design allows for easy sealing and unsealing of the vial, facilitating efficient sample handling and analysis.

Aijiren Headspace Vial and Cap facilitates automatic quality control or sample selection by performing headspace gas analysis. Common applications of Aijiren Headspace Vial and Cap include detection industry analysis, gas in polymers and plastics, volatile substances in beverages and foods, perfumes and cosmetics; also used to analyze the gasification of volatile organic solids and liquid samples. In recent years, the popularity of this technology has been recognized by laboratories around the world.

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 vials are typically larger than the 2 mL volumetric flasks used in many liquid sampling systems. Headspace vials are commonly available in 10 mL and 20 mL capacities.

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

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 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.

20ml precision screw headspace vial, 18mm, round bottom, top space vial, strong adsorption. Headspace vials are manufactured to provide uniform glass thickness which insures even heat distribution for consistent sampling reliability.

The China 18mm 10ml Screw Headspace Vial Supply is compatible with various headspace sampling techniques and instruments commonly used in the laboratory, such as gas chromatography (GC). The 10ml capacity of these vials is ideal for accommodating moderate sample volumes, facilitating efficient analysis while minimizing the need for frequent sample preparation. The screw top design allows for easy sealing and unsealing, enhancing convenience and workflow efficiency.

Aijiren Tech crimps 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 is also optional.

Crafted with precision from high-quality borosilicate glass, our 18mm 20ml Screw Headspace Vial ensures excellent thermal stability and chemical resistance. The vial’s robust construction guarantees sample integrity, enabling accurate analysis of volatile compounds for reliable results.

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.

Aijiren Tech Headspace Vial is manufactured to provide uniform glass thickness and ensures uniform thermal distribution for uniform sampling reliability. All Aijiren Tech Headspace Viars meet or exceed OEM manufacturer specifications. AijirenTech Vial is available in 6 ml, 10 ml and 20 ml versions, with screw and crimp types.

Aijiren’s Magnetic Precision Screw Metal Cap is 18mm in size, which is very suitable for sealing gas chromatography. This kind of cap is often used in headspace vials, and the center hole with it is very convenient for sampling by autosampler.

More convenient, consistent, and safer sealing process compared to crimping (better reproducibility). No risk of inaccurate or inconsistent crimping results. Due to thinner septa suitable for SPME as well as for Headspace. Often used on CTC Combi PAL and identically constructed autosamplers as well as on Perkin Elmer instruments.
Aijiren supply ND18 screw headspace vial in wholesale price, welcome to inquiry. You can also find Aijiren by those channel.

20ml precision thread headspace vial, 75×22.5mm, clear glass, borosilicate glass, round bottom
18mm combination seal: magnetic univerisal screw cap, silver, centre hole, ptfe/silicone or ptfe/butyl septa

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.

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.
