20mL Clear Headspace Vial, 23x75mm (for CTC PAL, PE), Round Bottom, 20mm Flat Top Crimp
| 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. |
