Biopharmaceutical Viral Filtration

Screening Effect

 

The hydrophilic modified PVDF membrane features strong anti-contamination capability, high membrane loading capacity, small dead volume, low adsorption, high recovery rate, and strong virus interception capability (LRV>4).

It offers high cost-effectiveness and batch stability. The virus removal efficiency (LRV) of PVDF is positively correlated with virus size, further demonstrating that PVDF filters remove viruses based on size screening rather than physical or chemical effects (e.g., adsorption). Therefore, as
long as the virus size meets the filter's exclusion specifications, even unknown viruses can be easily removed

 

The shell container of the same design features a membrane area determined by the number of hollow fiber filaments, ensuring reliable scalability from R&D to mass production. The hydrophilic PVDF material filter is available in five sizes: 0.003 m², 0.25 m², 1.0 m², and 4.0 m².

 

 

Suitable for high-pressure and high-concentration applications

PVDF filters are highly suitable for filtration under high-pressure and high-concentration conditions. The figure demonstrates a good correlation between filtration pressure and flow rate, maintaining a certain ratio even within the high-pressure range.
