Our headspace vials can be ordered as either flat or round bottom, and we offer many types of caps to be paired with your vial including, aluminum, pressure-released lined, and magenetic-lined seals.

Headspace vials and closures must form a tight seal for accurate analysis with reproducible results. Available in clear or amber Type I borosilicate glass with crimp or screw thread finishes. The vials are used to heat the sample until the concentration of the liquid and gas phases are in equilibrium. A sample is then taken from the gas phase (headspace) for analysis.
