What are the advantages of using acoustic wave separation?
It offers a small footprint, low contamination risk, and reduced filter fouling compared to traditional methods.
Can this method be used for continuous bioprocessing?
Yes, it provides a continuous flow of cell-free material suitable for downstream processes.
What is the impact of feed pump rate on cell removal efficiency?
Higher feed pump rates can decrease cell removal efficiency significantly.
How is the system primed for operation?
The system is primed by connecting feed tubing to the harvested cell culture fluid and starting the feed pump.
What cleaning procedures are recommended after use?
Flushing with deionized water and isopropyl alcohol is recommended to clean the system.
What turbidity levels indicate effective separation?
Consistent turbidity measurements around 40 to 50 NTU after separation indicate effective clarification.
