Description
Specifications

These closures with a molded, high purity Silicone/PTFE septa are only laminated with PTFE in the contact area with the sample. Thus the elastomeric Silicone 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.
