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.

Headspace borosilicate glass vials are a type of glass containers designed for storing and analyzing gas samples. They are commonly used in analytical chemistry and the pharmaceutical industry. The term “headspace” refers to the area above the liquid or solid sample in the vial, which contains the gas phase of the sample.
Borosilicate glass is chosen for these vials because it has low thermal expansion properties, making it resistant to thermal stress and thermal shock. This is important because headspace vials are often subjected to heating and cooling during the sampling process.

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

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.

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.
