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.
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, are common consumables generally used in gas phase experiments. Headspace samples are typically prepared in vials containing sample, dilution solvent, matrix modifier, and headspace. Volatile components of a complex sample mixture can be extracted from the non-volatile sample components and separated in the headspace or gas portion of the sample vial.
Aijiren Tech crimps top headspace vials are available in a flat or round bottom style, with clear or amber glass. Headspace closures are available in pre-assembled caps with septums or can be ordered individually. Pressure release, seal with lining, and seal with magnetic lining is also optional.
