Caps & Closures | DWK Life Sciences For applications involving automated transport of vials, magnetic caps are recommended. The cap liner or septa is the part of the cap which establishes a tight seal with the vial. Liners and septa can be laminated with PTFE on one or both sides, which results in high chemical resistance and a nearly inert barrier between sample and septa material.
