8 mm × 0.065 in Red PTFE/Silicone Septa
Overview
These septa are manufactured from a laminated PTFE/silicone construction, combining the chemical resistance of polytetrafluoroethylene (PTFE) with the resealability of silicone. Each septum measures 8 mm in diameter with a thickness of 0.065 in, suitable for use with compatible 8 mm crimp or screw cap closures.
The red PTFE/silicone configuration is designed to provide a secure seal while allowing repeated needle penetration for sample access in analytical workflows.
