Crimp closure, N 20, metal (magn.), center hole,Butyl l. gray/PTFE d. gray,3.0mm

Magnetic 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. This product is only centrically laminated, typically called Pharma-Fix. Septa are assembled, caps are ready-to-use. Septa are shown for illustration purposes only, images upside down.
