Vacuum Filter Membrane Material Quick Selection Guide

  • MCE (mixed cellulose ester) – used in the filtration of aqueous solutions and effectively binds trace proteins.
  • PVDF (polyvinylidene fluoride) – extremely low protein-binding, for filtration of non-aggressive aqueous and mild organic solutions, or where maximizing protein recovery is important.
  • Nylon – Provides a broad range of chemical compatibility for the filtration of either aqueous or organic solvents; hydrophobic; and can be used in a broad pH range.
  • PES (polyethersulfone) – low-affinity for proteins and extractable with a substantially faster flow rates than PVDF; suitable for pre-filtration and filtration of buffers and culture media.
