Crimp closure, N 20, alu.,blue/tin, center hole, Silicone white/PTFE beige,3.0mm

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. Septa are assembled, caps are ready-to-use. Septa are shown for illustration purposes only, images upside down.
