headspace 20mm screw vial

  • Release Date:2015-07-18
Description

Introduction 

Chromfilter® high quality headspace vials have a Beveled Edge neck for a secure seal, uniform glass thickness for even heat distribution and consistent sampling reliability.

  • 20mm Crimp neck with 6ml, 10ml, 20ml hold up volume. Available in flat or rounded bottom designs for accurate instrument compatibility.

  • Pre-assembled 20 mm crimp caps with septa are ready-to-use with any headspace crimp top vials.


Flat / Rounded bottom selection guide

A rounded bottom is more sturdy and thus more resistant to the high pressure within the vial during the heating process. Furthermore the vial slides more easily into the heating block when being transported by a magnet.

A flat bottom might be necessary when vials have to run within the instrument on a slightly downwards tendency.
