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 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.

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.

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.

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.

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.

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.

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.

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.
