Virus Prefilter

 

The Working Principle of Virus Filter

When fluids pass through the filter, they pass through the annular flow channel and enter the hose, which is connected to the inlet and outlet respectively. During the filtration process, the exhaust port at the top is opened and the fluid direction passes into the filtrate. When the filtrate fills the filter, all the air is squeezed out and the exhaust port of the bladder filter is screwed on. After the filtration is completed, open the exhaust port at the bottom of the filter to discharge the remaining filtrate. In this way, the capsule filter can effectively purify the fluid and achieve the purpose of filtration.

 

Virus Filter Membrane Materials

 

Polypropylene (PP) Membrane

 

Known for its chemical resistance and broad compatibility with different fluids.

FAQ

 

Q: What is a virus filter?

A: These filters have porous hollow fiber membranes, and the pore size distribution of each membrane is designed to trap viruses based on size while allowing the target protein product to pass through.

Q: What is a capsule virus prefilter used for?

A: A capsule virus prefilter is used upstream of virus filtration steps to remove larger particles, aggregates, and impurities from biological solutions. By reducing fouling load, it helps improve the capacity, stability, and consistency of downstream virus filtration processes in biopharmaceutical manufacturing.

Q: How does a virus prefilter improve filtration performance?

A: Virus prefilters protect sterilizing-grade or virus-retentive membranes by capturing suspended solids and protein aggregates before they reach the main filter. This reduces clogging, extends filter life, and helps maintain stable flow rates and consistent process performance.
