Viruclear™ VF Plus Virus Removal Filter, PES (CAT#: STEM-BC-0219-ZJF)

Viruclear™ VF Plus is a PES virus removal filter developed for biopharmaceutical applications such as recombinant proteins, monoclonal antibodies, ADCs, fusion proteins, Single-Domain Antibodies, and relatively stable bispecific antibodies. The hydrophilically modified Polyethersulfone Filter Membrane provides high protein throughput and high product recovery. Its asymmetric membrane structure and high porosity support high flux while maintaining robust small-virus clearance. The optimized membrane structure improves mechanical strength and component manufacturing yield. VF Plus can provide better filtration performance for selected process feeds and can be evaluated alongside Viruclear™ VF during process development.
