MS short thread screw seal ND9
This transparent seal is certified for GC/MS and LC/MS applications. It has a thinned penetration area and a diaphragm. There is no bleeding, and the seal is fully inert. Therefore a contamination of the sample is impossible. Nevertheless the screw cap is as easy to penetrate as a normal septum and just as tight.
