20mm 20ml Precision Screw Headspace Vial
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.
