Our precleaned, Type 1 borosilicate clear or amber glass vials are washed in non-phosphate detergent, rinsed three times with tap water, and rinsed with ASTM Type-1 organic-free water to remove detergent. Post cleaning, vials are assembled with PTFE/silicone septa and open-top polypropylene caps.

Headspace sampling is a type of sample introduction technique for gas chromatography (GC) and gas chromatography-mass spectrometry (GC/MS). For headspace techniques, the gas layer, or the headspace above the sample in a vial, is analyzed as opposed to withdrawing a volume from within the sample layer (Figure 1).

Chromatography vials typically have crimp, snap, or screw finishes. Closures may be pre-assembled with septa or the septa purchased separately. Vials with closures are also sometimes sold in pre-assembled sets. Crimp top finishes are used with aluminum crimp seals to create a more permanent closure.
