Consistently Superior Cell Growth: Achieved with New Polyethylene Film Formulation

During the past decade, single-use bioprocessing bags and bioreactors have gained a significant foothold in the biopharmaceutical industry because they offer a number of advantages over traditional stainless steel equipment, especially for clinical production, multiproduct facilities, and emerging economies. At the same time, some companies are concerned that plastic materials might release potentially toxic substances that could affect cell growth and product titers (1). In a worst-case scenario, they could even compromise drug safety when a company uses disposable bags…

Robust and Convenient Single-Use Processing: The Superior Strength and Flexibility of Flexsafe Bags

With the increased use of disposable bioprocessing bags in all critical process steps of the biopharmaceutical drug production, there is a growing requirement for high-quality, robust, and easy-to-handle bioprocessing bags. The new generation of films and bags must combine multiple mechanical, physical, and chemical properties to make these products suitable and scalable for all processing steps in upstream, downstream, and final filling operations, including cell culture in rocking motion and/or stirred-tank, single-use bioreactors as well as storage, mixing, shipping, and…
