New Restek PAL SPME fibers are high-performing fibers that meet or exceed the performance of other brands. Our reliable SPME fibers feature an aluminum hub that is more durable than plastic. These fibers are optimized for PAL system autosamplers and are compatible with most GC inlets. Restek SPME fibers are suitable for a wide range of analyte chemistries and sample matrices. Our SPME product line is continually expanding and currently includes SPME fibers for both polar and nonpolar target analytes across a wide range of molecular weights and volatilities.
Restek’s new Thermolite Plus septa offer advanced technology for optimal performance. The ultra-low bleed characteristic of these new septa minimizes the background signal, and the plasma coating prevents the septa from sticking in the injection port. Precision molding ensures a consistent, accurate fit. In addition, select Thermolite Plus septa feature a CenterGuide design to minimize coring.
