The main application of this membrane filter types is the air/gas-filtration. They are made purely of PTFE and are therefor permanentely hydrophobic. Unlike other (hydrophilic) filter types, they are not wetted by air humidity which allows unhindered passage of air even at low differential pressures. PTFE membrane filter have an excellent chemical compatibility, so that they are also used for the filtration of solvents and acids, to which other filters are not resistent. Due to their hydrophobic characteristics, they must be prewetted with ethanol or methanol before the filtration of aqueous media.

PTFE Membrane Filters Applications & Benefits:

  • Filtration of air and other gases, acids, bases and solvents where sterility is not required.
  • Outstanding chemical compatibility
  • Permanently hydrophobic
  • Excellent thermal resistance
  • Compatible with almost all acids, bases and solvents
  • Autoclavable at 121°C or 134°C
  • Dry heat sterilization possible
  • Unimpeded air passage even at low differential pressures
  • Reliable sterile filtration
