Orbitally Shaken Single-Use Bioreactor for Animal Cell Cultivation: Fed-Batch and Perfusion Mode

Increasing the cultivation volume from small to large scale can be a rather complex and challenging process when he method of aeration and mixing is different between scales. Orbitally shaken bioreactors (OSBs) utilize the same hydrodynamic principles that define the success of smaller-scale cultures, which are developed on an orbitally shaken platform, and can simplify scale-up. Here we describe the basic working principles of scale-up in terms of the volumetric oxygen transfer coefficient (kLa) and mixing time and how to define these parameters experimentally. The scale-up process from an Erlenmeyer flask shaken on an orbital platform to an orbitally shaken single-use bioreactor (SB10-X, 12 L) is described in terms of both fed-batch and perfusion-based processes. Learn More
