Butyl stoppers can be used when PTFE is not required. Butyl/PTFE septa are an economical choice with low background peaks. Molded PTFE/butyl septa offer the tightest seal of all PTFE items, as well as low background peaks. PTFE/silicone septa are excel

For use in removing fibrin and macro particles from serum to prevent line clogging. Users insert the 16 mm flange into the evacuated blood tube and push downward. Graduated barrel tells exactly how much liquid has been filtered. Wide-body style prevents sample probes from hitting side walls.

Your chromatography analysis does not end with the selection of the GC column. The combination of components selected for your instrument also make an important contribution to successful separations. Choose SGE technology to improve your chromatography.
