18 BioPharm International eBook June 2018 www.biopharminternational.com Single-Use Systems Qualification Qualif cation of Single-Use Systems An understanding of the unique nature of single-use systems, and how they interact with each biomanufacturing process, is important when qualifying single-use systems. T he polymeric nature of single-use systems creates the potential for extractables and leachables to impact the production of drug products. The qualification of single-use sys- tems is, therefore, different and more chal- lenging than stainless-steel systems. BioPharm International spoke with Andrew Bulpin, head of process solutions for MilliporeSigma; Danny Hower, extractables & leachables supervisor, SGS; Dr. Dujuan Lu, extractables & leachables technical client manager, SGS; Helene Pora, vice-president, technical communication and regulatory strategy, Pall Biotech; Eric Isberg, director of Life Sciences at Entegris; and experts from the Bio-Process Systems Alliance (BPSA) Technical Committee, about the challenges and pro- cedures involved in the qualification of single-use systems. SINGLE-USE VERSUS STAINLESS-STEEL BioPharm: What challenges are specific to the qualifi- cation of single-use systems compared with stainless- steel? How are these challenges addressed?
