Sterile filter systems selection

In selecting a membrane material, its pH compatibility and wettability should be considered. Some hydrophobic membranes require prewetting with a low-surface-tension solvent such as alcohol, whereas cartridges containing membranes are often presterilized using gamma irradiation. Such filter systems do not require assembly and steam sterilization. 

In the selection of sterilizing filters for compressed air systems (Figure 6.45), the following parameters should be fulfilled as the ...
