-
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
-
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
-
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
