General description

Polyethersulfone (PES) exhibits low protein binding, resulting in low chances of losing protein from media. It is hydrophilic and thus does not require external wetting agents or surfactants. PES offers higher aqueous flow rates. It has greater strength, capacity, and chemical resistance than cellulose acetate, nitrocellulose, or nylon.

Features and Benefits

  • The polyethersulfone (PES) membrane exhibits low protein binding, resulting in low chances of protein loss from media.
  • Hydrophilic PES does not require external wetting agents or surfactants.
  • Offers higher aqueous flow rates, greater strength, capacity, and chemical resistance that is optimized for use with most cell and tissue culture media.
  • The 0.45 μm membrane pore size is ideal for specialty applications, particle removal, and general clarification.
  • Non-pyrogenic and endotoxin-free.
