20ml Headspace-Vial, 75.5 x 23mm, clear glass, 1st hydrolytic class, rounded bottom, for PLASTIC screw caps ND18

- IMPORTANT SAFETY TIP: As Headspace vials have to withstand high internal pressure, almost all vials on the next page have a wall thickness of 1.2mm. Thus it is guaranteed that the vial will not burst. Contrary to a widely spread opinion, the seal and not the vial represents the weakest part of the whole sytem. Under pressure the septa will bulge against the Aluminum cap with such a force that the cap is torn apart. By own testing we varified that e.g. our PerkinElmer vial 20 09 0297 can easily withstand 10 bars or more while the seal is torn apart at around 10 bars when no pressure release system – like our Headspace Cap – is used.
- 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.
- Screw Caps are a novelty in the crimp neck dominated Headspace area. However, they represent a ready to use, convenient solution, that does not require any additional tools (crimpers, decappers). Thus samples can be taken and sealed out in the field without the necessity of sample transfer later in the lab. The magnetic Screw Seals can be used universally for Headspace as
