【Flat Bottom Finish】A rounded flat bottom might be necessary when vials have to run within the instrument on a slightly downwards tendency and preferred for manual headspace auto-samplers. And flat bottom maximizes heating efficiency. 【Fit for 20mm Capsl】The bottle size : 23*46mm/10ml. The headspace sample vials work with any 20mm cap.

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.
