PVDF Filters

PVDF Hydrophobic

  • Filtration of water-soluble oligomers and polymers, e.g. protein solutions.
  • Filtration of hydrophobic substances in different organic solvents.

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

  • This membrane features stability and hydrophobic interactions which is similar to PTFE. Naturally, hydrophobic membrane provides excellent flow rates and high loading.
  • Exceptional temperature stability provides extended sampling range over other membranes.

PVDF 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.

  • Low protein-binding for filtration of non-aggressive aqueous and mild organic solutions.
  • Low UV absorbing extractables and low nonspecific protein binding.

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

  • Hydrophilic membrane with good solvent resistance.
  • It has superior performance to prevent leak of sample solvent and can promise membrane area being used in a large filtration area.
