China 18mm Headspace Vial Screw Vial Supplier

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.

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.

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.

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.

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’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.

The metal cover provides the widest temperature tolerance range and is very resistant to impact cracking. The metal cover is very suitable for gas chromatography applications. The metal cover is made of steel (chrome-plated or tinplate anti-corrosion coating) or aluminum.
