2） Product Overview

  • Low protein adsorption, suitable for filtering mild aqueous solutions and weakly organic solvents without strong corrosivity.
  • Minimal UV-absorbing extractables and ultra-low non-specific protein binding.
  • Ideal for filtering water-soluble oligomers and polymers such as protein solutions.
  • Capable of filtering hydrophobic substances dissolved in various organic solvents.
  • Two standard pore sizes: 0.22 μm and 0.45 μm.
  • Four outer diameter specifications: 4 mm, 13 mm, 25 mm, 30 mm.
 

3） Key Features

  • PVDF membrane with built-in PP pre-filter doubles filtration throughput compared to single-layer standard filters (4 mm excluded)
  • Hydrophilic membrane with outstanding solvent resistance
  • Stable membrane performance, featuring hydrophobic interactions similar to PTFE
  • Custom packaging service available

4） Applications

  • Sterile filtration and clarification of biological liquid samples
  • Broad chemical compatibility, resistant to corrosive acids and alcohols
  • Sample filtration scenarios requiring high protein recovery
  • Gas, vapor and high-temperature filtration
  • Filtration for food manufacturing and pharmaceutical industry
