Headspace ND20 (ND18)

Headspace Vials might differ in:

  • Volume (5ml, 10ml, 20ml)
  • Rounded or flat bottom
    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.
  • Bevelled top or flat DIN Crimp Neck/Screw Neck
    A bevelled top Headspace Neck might be required for some special closure systems (PerkinElmer), however, a liner has more surface to lie on with a flat DIN Crimp Neck. The more surface for the liner to rest on, the tighter the seal.
  • Length of the Neck (instrument specific)
  • Clear/Amber Glass
  • With/without label and filling lines
  • Upon request with a barcode label
