Durapore® PVDF Membrane Filters

Durapore® PVDF Membrane FiltersThe best-known properties of Durapore® Polyvinylidene Fluoride (PVDF) Membranes are their extremely low protein binding and minimal interaction with sample components. Binding less protein per unit surface area compared to nylon, PTFE, or nitrocellulose membranes, Durapore® filters are commonly used to clarify and sterilize protein-containing solutions.

Durapore® Membrane Filters are available in multiple pore sizes. Both hydrophobic and hydrophilic filters are available to match application requirements.

Key applications of Durapore® filters:

  • Sterilizing filtration
  • Filtration of protein-containing solutions
  • Mycoplasma reduction
  • Filtration of gases
  • Venting
