Headspace screw neck vials with precision thread, ND18. Vials Chromatography Vials. Vials, closures, septa and kits. No risk of incorrectly sealed vials as is the case with crimping. More convenient to close and open, especially as magnetic crimp caps are very hard to crimp. Lower coring and protection for the needle due to thinner septa.

The testing is also completed to confirm that the vials are free from any impurities that may cause problems for accurate chromatographic results.
