PROPOR SG

  • Polyethersulfone (PES) membrane
  • 0.2µm rated, sterilising grade
  • Also available in 0.1µm and 0.45µm
  • High flow rates = smaller filter required / quicker processing time
  • High throughputs = larger batches
  • Low product binding = higher product yield
  • Broad-spectrum chemical compatibility
  • Low extractables = low leachables into drug product
  • Example applications: buffer filtration, final fill

PROPOR HC

  • Polyethersulfone (PES) membrane
  • 0.2µm rated, sterilising grade
  • Integral PES highly asymmetric pre-filter layer 0.6µm
  • High capacity, high dirt holding = high throughput with difficult to filter products
  • Broad-spectrum chemical compatibility
  • Example application: Growth media filtration

PROPOR BR

  • Polyethersulfone (PES) membrane
  • 0.2µm nominally rated, non-sterilising
  • Integral polyester pre-filter layer
  • Bioburden reduction
  • >5log reduction ASTM F838
  • High flow rates = smaller filter required / quicker processing time
  • Low product binding  = higher product yield
  • Broad-spectrum chemical compatibility
  • Example application: Chromatography or TFF pre-filtration
