Virus removal filtration is often due to various reasons, resulting in low filtration capacity, increased cost, increased process time, and resulting in increased process risk and other problems. Without changing the state of the sample, adding virus removal pre-filter is the most effective solution.

Tofflon Saipu specially designed the Vshell® Virus Removal Pre-filter to complement the Valpha® Virus removal filter to provide reliable virus removal protection while increasing the capacity of the virus removal filtration.

Selection of virus removal pre-filter

The purpose of virus pre-filtration is to remove various impurities or contaminants such as protein aggregates, DNA, and other trace sub- stances. The size of the pre-filter also has a significant impact on the viral filter load.
