Bimetal cap, N 20, blue/silver, hole, silicone white/PTFE beige,3mm

Description

Bimetal crimp caps allow the bottle to be transported using magnets, e.g. in the CTC Combi PAL, the Shimadzu AOC 5000/6000 or the Gerstel autosampler. They are generally more difficult to crimp/uncrimp, so the N 18 headspace threaded bottles can be a more convenient alternative. We recommend silicone/PTFE septa as the optimal choice for headspace applications, as they offer temperature stability from -60 °C to 200 °C, maximum analytical purity and excellent penetration properties. The septa are fitted and the caps are ready for use. For illustrative purposes, the septa are shown with the underside facing upwards.
