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.

18mm Screw Headspace Vial Features

  • 20ml precision screw headspace vial, 18mm,22.5x75mm, round bottom, headspace vial with strong adsorption.
  • It is easy to use and does not require any additional tools such as cappers and uncappers.
  • The precise screw thread ensures an airtight seal between the vial and the cap.
  • The magnetic screw cap can be used for a wide range of SPME and headspace analyses.
GC headspace works on the principle that an equilibrium must be achieved between the volatile analytes in the sample matrix and the headspace (i.e., the gas phase in the sample vial or container) above the sample matrix. The samples evaporate into their respective headspaces upon heating.
