A headspace vial is used in the process of top – gas chromatography. When detecting volatile or semi-volatile mixtures with high boiling points, we need to heat them to vaporize them at the top. In this process, since the liquid samples are at the bottom, the material in the top gas can be measured without touching the liquid in the sample vial.
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.
Aijiren Tech headspace vials are manufactured to provide uniform glass thickness which insures even heat distribution for consistent sampling reliability. All Aijiren Tech headspace vials meet or exceed OEM instrument manufacturer’s specifications. Aijiren Tech vials are available in 6ml, 10ml, 20ml versions with Screw and Crimp type.
20mm crimp headspace vial is widely used in Headspace and GC, GCMS application.
20mm Aluminum Crimp Cap Seals and Vials ensure that a proper seal is made for this demanding application
Vials are manufactured of borosilicate glass and include a write-in patch for sample identification.
Caps are made of high quality laquered aluminum, 0.010" thick
Cap colors are available in silver only
Many septa options are available and use only the highest quality materials to ensure proper function and can be pre-slit to ease needle penetration
0.120" Natural Silicone with 0.005" Natural PTFE. Designed for highly demanding volatile analyses (Headspace) up to a maximum of 200C
High quality silicone compounds are used to ensure proper re-sealing and reduced chances of coring
Septa is pre-conditioned to ensure low bleed
Absence of pigments eliminates additional sources of contamination
Aijiren Tech crimp top headspace vials are available in a flat or round bottom style, with clear or amber glass.

Flat bottom vials maximize heating efficiency when used with bottom
A rounded bottom is more sturdy and thus more resistant to the high pressure within the vial during the heating process. Furthermore the vial slides more easily into the heating block when being transported by a magnet.
Round bottom vials are designed for Perkin Elmer™, Tekmar™ and Varian™ units
