China Wholesale 18mm 20ml Screw Vial GC Headspace Vial

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

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.

The 18mm Screw Headspace Vial and Cap with electromagnetic screw seals used for CTC is novel in the headspace vial market dominated by crimping necks. Especially for magnetic caps that are difficult to crimp, screw caps are a convenient choice. 18mm Screw Headspace Vial and Cap with aluminum skirt and magnetic center plate, it is easy to crimp and remove the cap. 18mm Headspace Vial and Cap is preferred for the following instruments: CTC PAL, Varian, Gerstel, Atas, Shimadzu, Aijiren.

Headspace vials can withstand the higher temperatures and internal pressures required for volatile gas analysis. With very low metal content, extractables and leachables, they meet high standards to meet your regulatory requirements. These headspace vials have been specification certified for physical dimensions and autosampler compatibility.

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.

Screw 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 suitable for headspace analysis of volatile solids and gases.

Aijiren provides Screw Thread Headspace Vial always be applied to Aijiren, Shimadzu, Tekmar, CTC PAL, Varian, Gerstel, Atas, Thermo Scientific autosamplers. Aijiren’s Screw Thread Headspace Vial are all round bottom, this is because A rounded bottom is more sturdy and thus more resistant to the high pressure within the vial during the heating process.

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.

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.
