Sterile Syringe Filters

Thermo Scientific Nalgene sterile syringe filters are ideal for sterilizing (0.2 micron) or clarifying biological solutions, such as cell culture and microbial media, reagents and additives, proteinaceous solutions, and buffers.

  • PES (polyethersulfone) – Lowest protein binding and extractables, fast flow rates; best choice for media
  • SFCA (surfactant-free cellulose acetate) – Low protein binding, lower extractables than standard CA; useful for cell culture fluids and cellular solutions
  • CA (cellulose acetate) – Some protein binding and extractables; good for buffers
  • Nylon – Low extractables, high protein binding; recommended for alcohols and weak solvents
