CHROMAFIL® GF  
Syringe filters with glass fiber membrane  
 Features
  • 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, they prevent plugging of the membrane.

Chemical compatibility of filter materials  
The following table lists the chemical compatibility of our CHROMAFIL® materials. The chemical compatibility depends on several parameters such as time, pressure, temperature and concentration. In most cases, CHROMAFIL® filters will have only short contact with a solvent.   In these cases they may be used despite of 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.
