Cellulose Nitrate Membranes

Recommended for clarification and sterilisation of aqueous solutions, microbiological analysis and particle

counts.

 

  • Made of cellulose nitrate, hydrophilic.
  • Very high flow rate
  • High non-specific adsorption.
  • Qualified for aqueous solutions (pH 4-8), hydrocarbons and some dilute solvents.
  • Very uniform pore structure which ensures homogeneous distribution of the particles retained on the filter surface.
  • Maximum temperature 130ºC
  • Available in white or black, gridded (3.1 x 3.1 mm) or plain, sterile or non-sterile.
  • Pore size from 0.2 μm to 8 μm with a sharp size distribution
  • Filter diameters from 25 mm to 50 mm
