Biopharmaceuticals commonly cannot be terminally sterilised, as such aseptic processing using sterilising grade filtration is essential.

The authors describe the origins of single-use components and explain their application to aseptic processes. They also show how disposable devices have changed over time and offer a glimpse of the future.

Pre-use integrity testing of sterilizing-grade filters eliminates the potential adverse effects of filter loading on the integrity-test results, allowing unambiguous correlation with the integrity-test specification established during filter-validation studies.

Pore-size ratings are so unrelated to actual dimensions and so subject to anomalous interpretations as to make substantial dependency upon their values an unwise choice. Moreover, the means of measuring them are questionable. The pore-size rating system at best provides a qualitative differentiation.

The authors encourage the investigation into whether the occurrence of grow-through and the diminution in the size of certain organisms when in contact with given liquids are the same phenomenon manifested under different circumstances.
