Headspace 20Ml Screw Vials are an alternative to crimp top Headspace Vials. The design allows a leak tight seal with moderate twisting force. Since they do not require crimping, samples can be taken and sealed in the field without the need for sample transfer in the lab. Vials can be used either for traditional headspace analyses or SPME.

Dec 14, 2009 · To crimp is the physical act of attaching both the septum (the membrane that the needle passes through) and the cap (the metal ring) to the headspace vial as demonstrated below. The devise used to do so is called a crimp (kind of like a walnut cracker). As headspace gas chromatography (as opposed to direct injection) is based upon Henry’s law.

Headspace vials are available with either a round or flat base; Round bottomed vials are compatible with most autosamplers and are more easily handles by robotic arms that lift vials from the tray; Flat bottom vials maximise heating efficiency in manual headspace sampling and are required for use in some instrument models
