What is a pneumatic bioreactor?
A pneumatic bioreactor is a system that uses air pressure to control the growth environment for cells.
How do you calibrate the pH sensor?
The pH sensor is calibrated using standard buffer solutions at pH 4 and pH 7.
What are the advantages of using a single-use bioreactor?
Single-use bioreactors reduce the risk of contamination and simplify the cleaning process.
What types of cells can be grown in this bioreactor?
This bioreactor is designed for the growth of mammalian cells.
How is the oxygen saturation maintained?
Oxygen saturation is controlled through the bioreactor's gas supply and monitoring systems.
What is the role of micro carriers in this process?
Micro carriers provide a surface for cells to attach and grow in suspension culture.
