CHROMAFIL® Syringe Filters – Glass Fiber (GF)

  • Inert filter, nominal pore size 1 µm, allows higher flow rates than small pore filters
  • For solutions with high loads of particulate matter or for highly viscous solutions (e. g. soil samples, fermentation broths)
  • As prefilters for other CHROMAFIL® filters, prevents membrane plugging
  • Used alone, filters allow higher flow rates than e.g. a 0.45µm filter

CHROMAFIL Disposable Filters

This table lists the chemical compatibility of our CHROMAFIL materials. The chemical compatibility depends on several parameters such as time, pressure and concentration. In most cases, CHROMAFIL filters will have only short contact with a solvent. In these cases they may be used despite limited compatibility. For example, a PTFE filter with PP housing does not liberate any UV-detectable substances during filtration of 5 ml THF, although PP shows only limited resistance towards THF.
