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.)
