Buy Screw Top Headspace Vials from China Supplier

The headspace sample bottles are available in 10 types of 10mL and 20mL volumes, with flat or round bottoms. The 20mm crimp cap provides an always guaranteed seal. Crimping or screw-top vials are available, with a beveled top for maximum safety sealing, two neck lengths are available, and flat-bottom or round-bottom designs are available.

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.

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.

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

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.

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.

Gas in the vial enters the gas phase detection. Top-space gas analysis using headspace viars can help automate quality control or sample selection. Use state-of-the-box equipment to prepare your entire experiment for accurate analysis through repeatable samples.

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.

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.

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.

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.

A headspace vial is used in the process of top – gas chromatography. 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.
