The Viresolve® Prefilter will improve the filtration economics of the viral clearance step by providing protection for Viresolve® NFP viral clearance filters. Use of this prefilter with NFP will improve capacity and increase the life of the NFP filter. Available in scalable filter formats, this prefilter will easily fit in existing development and manufacturing processes.
Enhanced Viral Clearance
Viresolve® NFP filters clear parvovirus from recombinant feed streams without compromising flow rates, adding speed and dependability to viral clearance in therapeutic drug manufacturing applications. These reliable filters are ideal for monoclonal antibody polishing applications eliminating small virus contaminants.
Improves NFP capacity reducing overall filtration costs
- Maintain high product yields
- Simple, predictable scale-up and scale-down
Increased Capacity and Filter Life
Utilizing this prefilter in series with Viresolve® NFP filters (NFP) will allow you to take advantage of NFP’s high flow rates and product yield. The prefilter effectively removes fouling components of the feed, leading to dramatic increases in the performance of the Viresolve® NFP filter. This improved capacity significantly reduces the cost of the viral clearance step.
