CELLULOSE ACETATE MEMBRANE FILTERS


DESCRIPTION

    

Recommended for aqueous samples, biological applications and protein filtration.
  • Made entirely from pure cellulose acetate.
  • Hydrophilic.
  • High flow rate.
  • Thermal stability.
  • Very low adsorption.
  • Suited for use in pressure filtration devices.
  • Resistant to aqueous solutions pH 4-8 , most alcohols, hydrocarbons and oils.
  • Pore size from 0.20 µm to 0.80 µm.
  • Filter diameters from 13 mm to 293 mm.
  • White and plain surface.

APPLICATIONS

  • Filtration of aqueous solutions.
  • Sterilisation of cell and biological solutions (membranes with a pore size of 0.20 µm are specially recommended when the recovery of protein is critical).
  • Filtration of proteins and enzymes.
  • Biological and clinical analysis.
  • Sterilisation of culture media.
