Headspace screw neck vials and magnetic screw closures N 18 

Headspace screw neck vials N 18
More convenient, consistent, and safer sealing process compared to crimping (better reproducibility)
No risk of inaccurate or inconsistent crimping results
Magnetic screw closures N 18
Thinner septum (1.5 instead of 3 mm), thus safe penetration of the needle and less fragmentation (especially important for SPME applications)
Flat surface for the magnet; thus the filled vial cannot drop from the magnet 
(In case of over-crimped vials, this can happen due to the convexity of the cap.)
