Headspace vials are one of those rare laboratory supplies that are appropriately named: headspace vials are lab vials with extra space at their top (head). Simple! They’re typically used in autosampler machines in chromatography, and for that reason are sometimes called autosampler vials or chromatography vials.
Headspace vials are available in two major styles: crimp top and screw thread. Crimp top vials have a metal cap that’s closed with a handheld crimper. Neat. Screw thread vials have a simple screw cap, just like that cheap wine you keep buying. Both types employ stoppers or septa between the cap and the vial, depending on the application.
At Growing Labs, we don’t sell the name brand headspace vials. Small and medium labs don’t have the budget to waste on vanity name brands; they buy acetaminophen, not Tylenol, because it’s the same thing – except much cheaper. That’s one of our specialties: offering equivalent alternatives so that our customers can save on budget.
