MilliporeSigma Launches Viresolve Barrier Filters

MilliporeSigma has introduced Viresolve Barrier capsule filters to reduce the risk of bioreactor contamination.  The filters are designed to remove viruses, mycoplasma and bacteria from cell culture media.

Viresolve Barrier filters are a part of MilliporeSigma’s Viral Safety Assurance Program, to mitigate the risk of viral contamination in upstream bioprocesses and minimize the potential impact on drug supply and patient safety. The program offers solutions to prevent viruses from entering upstream processes, detect viruses in cells, raw materials and process intermediates and remove viruses in downstream processes. 

“Viral contamination is a constant process threat,” said Andrew Bulpin, head of the Process Solutions business area at MilliporeSigma. “One viral particle has the potential to initiate a bioreactor contamination. Our new Viresolve Barrier filters reduce the risk of bioreactor contaminations that cause process downtime, costly investigations and possible drug supply disruptions that could impact patients.”

The filters are available now in sizes up to one square meter, including scalable micro filters for process development.
