Crimp closure, N 20, alu., center hole,Butyl d. gray/PTFE gray,high purity,3.0mm ICP-122-L 7-TrimethylbenzothiopheneSimilar product as 70234, however, with a higher analytical purity. These closures with molded Butyl PTFE septa are only laminated with PTFE in the contact area with the sample. Thus the elastomeric Butyl can achieve on the vial's glass rims a very tight seal, while in comparison a completely PTFE covered septum would have a very slippery surface on the glass and could easily be twisted around.
