Design, Characterization, and Scale-Up Strategy for a New Single-Use Production-Scale Bioreactor

<p> The design of the initial range of single-use stirred bioreactors was cylindrical, essentially copying that of traditional stainless steel bioreactors. The cylindrical shape with dished ends was intended to minimize the expensive steel stainless wall thickness and still be strong enough to withstand the internal pressure developed during steam sterilization. However, since single-use biocontainers can be supplied presterilized, novel shapes can now be considered. Indeed a square cross-section design demonstrates some significant advantages over a cylindrical one.</p> <p> This GEN webinar will first introduce and discuss the engineering concepts of the Allegro™ STR bioreactors, a square bioreactor design with volumes of 200 L, 1000 L, and 2000 L, and then utilize these concepts to demonstrate scale-up from the bench with a live culture.</p> <h3> Who Should Attend</h3> <ul> <li> Upstream bioprocessing engineers</li> <li> Upstream process development scientists</li> <li> Clinical and commercial manufacturing supervisors and technicians</li> <li> QA/QC scientists</li> </ul> <h3> <br /> You Will Learn</h3> <ul> <li> Why a square cross-section brings significant advantages to the upstream process, for handling, process assurance, while maintaining optimal cell culture performance</li> <li> About the performance of a square-shaped bioreactor, in terms of mixing efficiency, mass transfer of oxygen (kLa), and CO<sub>2</sub> stripping</li> <li> Applying system engineering principles toward bioreactor characterization, and how tech transfer methods are leveraged across designs, from the bench to production vessels</li> </ul> <p>  </p>
