Magnetic screw caps, ND18 and septum
The magnetic screw closures are ready assembled with septa suitable for headspace GC.
- Magnetic srew caps with or without center hole
- Flat surface of cap for a safe grip at the magnet
- Thinner septum (1,5 instead of 3 mm) for a precise penetration of the needle (especially for SPME)
- Septa made from high quality silicone/PTFE (also slitted), Butyl/PTFE or Red Rubber/TEF
