Crimp closure, N 20, alu.,blue/tin, center hole, Silicone white/PTFE beige,3.0mm Gradation - Ozone - < 90 • 90–150 • 150–210 • > 210 µg/m³ O₃ The QuEChERS (pronounced as “catchers”)Bi metal crimp closures support transportation of the vial via magnet, as for e. g. in the CTC Combi PAL, the Shimadzu AOC 5000 6000 or the Gerstel autosampler. They are generally more difficult to crimp decap which is why Headspace screw neck vials N 18 may be a more convenient alternative. We recommend Silicone PTFE septa as the optimal choice for Headspace, as they offer a temperature resistance form 60 C up to 200 C, highest analytical purity and
