Customer success stories

Bioprocessing scale up involves the increase in working volumes from small scale through to production scale. During scale up it is desirable to reproduce the process performance, which has been optimized at small scale, at larger scale, ideally without much need for process optimization at large working volumes. This requires reproducing the cells’ or organisms’ growth environment across scales. Several factors play a role in a reliable bioprocess scale up. Kinetics and thermodynamics are virtually unaffected by the reaction volume. However, the mass transfer within a process is highly dependent on the scale. On this page you can learn more about the parameters to control during bioprocessing scale up, as well as several strategies to ensure maximum efficiency and product quality is maintained.

Bioprocess scale up strategies

An established strategy when transitioning to larger working volumes is to monitor and control a single parameter. However, keeping one process parameter constant will change others; therefore, the cells’ growth environment can only be partly reproduced at different scales. Bioengineers must identify the parameters which influence cell growth and productivity most, to decide, which scale up strategy is the most suitable. Although bioprocessing scale up strategies that control several criteria are the most powerful, those that control singular parameters can still be effective, and are historically the most widely used due to their simplicity. Read on to learn more about common singular parameters to control.

Eppendorf offers solutions for powerful bioprocessing scale up

The Eppendorf portfolio of bioreactor systems and vessels supports the seamless scale-up of cell culture and microbial bioprocesses from small-scale development to pilot production,using either single-use or reusable bioreactors.

Scale up from development to production with Eppendorf bioreactor systems

Eppendorf offers a comprehensive range of bioreactor systems for small-, bench-, pilot-, and production-scale applications to meet your bioprocessing needs. Our bench-scale bioprocess controllers support a broad range of working volumes, enabling you to scale from development to production on a single platform. This helps reduce equipment-related variables and supports a smoother, more consistent scale-up process.

Scale Up Assist for simplified scale-up

The Eppendorf applications team has characterized key scale-up parameters, including oxygen transfer rate (OTR), volumetric mass transfer coefficient (kLa), impeller power numbers, tip-speed ranges, and vessel geometries, for many of its bioreactor systems. These parameters are available to help streamline bioprocess scale-up. The BioFlo^® 320 and BioFlo^® 720 bioreactor control systems feature the Scale Up Assist software feature, which automatically calculates the parameter adjustments required for different vessel sizes.

Moving to a bioreactor

On this page we focus on bioprocessing scale up from small to large bioreactors. If you are currently cultivating your cells or organisms in shake flasks or dishes, this first requires a process transfer from shakers or incubators to bioreactors.
