Drug Substance Purification

Drug substance purification is a critical process step due to the risk of impurities being introduced either during the process or with the products used in biomanufacturing – but the integrity of the drug substance can also be at risk. The Flexsafe® Pro Mixer features a levitating impeller to preserve the drug substance during low shear blending applications and a design that supports taking off-line samples for other quality control tests prior to sterile filtration.
