Advantages of the BioSep perfusion system:

Continuous nutrient supply:
Perfusion bioreactors continuously feed fresh media containing essential nutrients, promoting sustained cell growth and productivity.
Enhanced cell density:
The continuous removal of waste products prevents the accumulation of inhibitory metabolites, allowing for higher cell densities and increased production yields.
Longer culture durations:
Perfusion cultures can be sustained for longer periods compared to batch cultures, leading to extended production runs and higher overall product yields.
Improved process control:
Perfusion systems offer greater control over culture parameters such as pH, dissolved oxygen levels, and nutrient concentrations, resulting in more stable and reproducible production processes.
Higher product quality:
The controlled environment of perfusion processes in biopharmaceutical production and perfusion bioreactors minimizes stress on cells and helps maintain product quality, resulting in higher purity and potency of the final biopharmaceutical product.

Operating principle

The Resonator Chamber of the BioSep device is seamlessly integrated into the bioreactor setup, with the cell suspension pumped into the chamber by a circulation pump. The flow is then divided between the harvest flow and the return flow, with the resonator controlling the flow rate. Ultrasonic forces within the resonator aggregate and hold suspended cells stationary against the flow, clarifying the harvest stream and promoting efficient cell retention. This continuous clarification ensures optimal cell viability and productivity throughout the perfusion culture. Planar aggregates formed by the ultrasonic forces are easily recycled back to the bioreactor for dispersion and continued cultivation, maximizing product yield and minimizing wastage.
