Viral Clearance

Viral safety is a critical aspect of biologics production and relies on the principles of "prevent, detect and remove" to assure viral safety of drugs for patients. Preventing contamination of upstream cell culture processes relies on sourcing and testing raw materials and different technologies to remove viral contaminants. Downstream purification includes steps that either remove or inactivate viruses to provide the clearance required to assure viral safety. 

Our viral clearance portfolio includes the virus filtration solutions, chemicals, holders and systems you need to assure reliable viral safety for your production process.
