Membrane filter, cellulose acetate (CA)

CA (Cellulose Acetate) membrane filters are composed of pure cellulose acetate modified to offer researchers the lowest binding filters available. Because of their unique strength and extremely low binding characteristics these filters are ideal for protein and enzyme filtrations, tissue culture media sterilisation, cold sterilisation, biological fluid filtration and other filtration applications where maximum recovery of proteins is critical.lowest binding material availablehydrophilichigh throughputstrength and dimension stabilityuniform pore structureThese filters are compatible with our vacuum filter flasks and manifold systems however the...

CA (Cellulose Acetate) membrane filters are composed of pure cellulose acetate modified to offer researchers the lowest binding filters available. Because of their unique strength and extremely low binding characteristics these filters are ideal for protein and enzyme filtrations, tissue culture media sterilisation, cold sterilisation, biological fluid filtration and other filtration applications where maximum recovery of proteins is critical.


  • lowest binding material available
  • hydrophilic
  • high throughput
  • strength and dimension stability
  • uniform pore structure



These filters are compatible with our vacuum filter flasks and manifold systems however they can be used in many other 3rd party set ups.

High quality membrane disc filters that give consistent and reliable results and are optimised for HPLC media preparation, pharmaceuticals and cold sterilisation.

Available Materials:

  • Nylon
  • Mixed Cellulose Esters (MCE)
  • Mixed Cellulose Esters (MCE) Grid (w/ pad optional)
  • Polyethersulfone (PES)
  • Polytetrafluoroethylene (PTFE) Hydrophobic
  • Cellulose acetate (CA)
  • Polypropylene (PP)
  • Polyvinylidene fluoride (PVDF)
  • Glass Fiber

Most common size for microbiology is 0.22µm pore, 47mm diameter.

However we have ready access to many other sizes including;

Pore sizes: 0.1um, 0.22um, 0.45um, 0.8um, 1.0um, 3.0um, 5.0um

Diameters: 13mm, 25mm, 47mm, 90mm, 142mm, 293mm

Custom sizes may be available, however a minimum order of 10 packs would normally apply, please contact us.
