 - Rugged stainless steel construction ensures longer lifetimes.
- Faster extraction means higher sample throughput.
- Better sensitivity allows lower LODs.
View Product Information |
 - Suitable for a wide range of analyte chemistries and sample matrices.
- Reliable performance meets or exceeds other brands.
- Robust aluminum hub is more durable than plastic.
- Optimized for PAL system autosamplers and compatible with most GC inlets.
- SPME automated sample preparation reduces sample handling and solvent consumption.

 - 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.
