- Crimp closure, N 20, alu., center hole,Butyl d. gray/PTFE gray,high purity,3.0mm
Similar 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.
