Key findings
The study investigated the impact of varying flow rates and rotor speeds on the performance of the DynaSpin Centrifuge. The primary objectives were to:
- Optimize separation efficiency
- Maximize product yield
- Minimize operational costs
Optimization of operational parameters
Adjusting the flow rate and rotor speed demonstrated a significant effect on the centrifuge’s performance. Lower flow rates were found to maximize separation efficiency but increased processing time. Conversely, higher flow rates reduced processing time but led to increased cell lysis and turbidity in the centrate.
Impact on cell lysis and clarification
Higher flow rates resulted in greater cell lysis, which negatively impacted the quality of the harvested product. This finding underscores the importance of balancing flow rate adjustments to maintain product integrity.
Economic and sustainability considerations
The study also highlighted the economic trade-offs involved in the optimization process. By fine-tuning operational parameters, the number of filters required post-centrifugation was reduced, leading to lower material and labor costs. Additionally, optimizing these parameters contributed to sustainability efforts by decreasing water and plastic waste.
Conclusions
The optimized settings for the DynaSpin Single-Use Centrifuge led to a notable improvement in separation efficiency and product yield. The balance between rotor speed and flow rate adjustments enabled a reduction in operational costs while maintaining high product quality. These results demonstrate the centrifuge’s capability to help enhance bioprocessing efficiency, cost-effectiveness, and sustainability, demonstrating the value that the DynaSpin Single-Use Centrifuge provides for those involved in mAb production.
