Thermo Scientific PTFE/Rubber Laminated Discs are flat discs composed of structurally bonded PTFE (5 mil thick) and white pharmaceutical-grade rubber (55 mil thick) layers for use as in-cap liners and septa for various kinds of screw cap vials. When used with compatible open caps and glass vials, the discs provide a complete, inert seal and direct access to samples with a syringe needle.
