 - Micro-thin septum center pierces easily without bending needles or breaking SPME fibers.
- Thicker outer septum wall secures septum in place and ensures a tight seal.
- Versatile closures are suitable for SPME as well as dynamic and static headspace applications.
- Septa are manufactured from low-extractability silicone and molded for dimensional conformity.
- Available in magnetic 18 mm screw caps and 20 mm crimp caps.
