Combi syringe filters with a coarse glass fiber profiler and a small-pore membrane as main filter. Disposable syringe filters Chromafil® are ready-to-use filtration units, which are filter elements incorporated in a polypropylene housing. Because every filter is only used once, contaminations are avoided. Syringe filters are used for filtration of suspended matter from liquid samples or gases. With Chromafil®, rapid purification and removal of particles is very simple: Just place the filter on the syringe, and you are ready for filtration. Special manipulations are not required. Contamination of sensitive instrumentation by solid impurities can be avoided, thus increasing lifetime of chromatographic columns and equipment.

  • The technology: The glass fiber membrane (1 µm) removes coarse particles, before they can block the fine main membrane; this results in a better filtration efficiency, specially for highly contaminated samples
  • Combi syringe filters with a coarse glass fiber prefilter and a small-pore membrane as main filter
  • For solutions with a high load of particulate matter lower back pressure, easy filtration
  • For high yields of filtrate: More ml of pure filtrate per filter
  • Recommended for filtration of biological samples with high particle loads
  • Suited for filtration of aqueous samples
