PTFE Filters

PTFE Hydrophobic

  • Hydrophobic PTFE membrane has great temperature resistance.
  • Suitable for Solvents/Gases/Acids/Bases.
  • Excellent chemical compatibility for filtering harsh chemicals that destroy other membrane materials and ideal for aerosol sampling.

Two types in pore size: 0.22μm and 0.45μm
Two types in filter size: 13mm & 25mm

PTFE Hydrophilic

Hydrophilic material has a great affinity for water and it’s easily wetted by water because of the surface with water molecules to form intermolecular forces.

  • High mechanical and tensile strength.
  • Used for most organic solvents and mid-polar liquids.
