PTFE membrane filter

PTFE Filter is a sterilizing grade air or solution filter that utilize naturally hydrophobic material provides effective retention of microbes and particles in air/gas or solutions. 

                                                             Micron: 0.01, 0.02, 0.1, 0.22, 0.45, 1, 3 5, 10 µm
Features
  • Inherently hydrophobicity.
  • High flow rates at low differential pressures.
  • High steam cycle lifetimes and thermal strength.
  • Reliable separation of microorganisms and bacteriophage.

Hydrophilic PTFE filters are also optional. Hydrophilic PTFE Filter could be wetted by aqueous liquid that utilize modified hydrophilic material. It is a sterilizing grade filter capable in organic solvent, mixed solvent, acid or alkali and other solutions.

Features
  • Hydrophilicity.
  • High flow rates at low differential pressures.
  • High steam cycle lifetimes and thermal strength.
  • Low exudates.
  • Broad chemical compatibility.
  • Reliable separation of microorganisms and bacteriophage.
