Bioreactors are core equipment in the bioengineering industry. Peristaltic pumps, due to their advantages of being pollution-free, having low shear, and offering high precision, have significant advantages in bioengineering applications and are the primary choice for fluid transport in bioreactors.
Factors to consider when selecting a peristaltic pump for a bioreactor system include:
- Flow Rate and Precision of the Peristaltic Pump
The flow rate of the peristaltic pump should be selected based on the process requirements of the bioreactor, while also considering the on-site precision requirements. Note that the required flow rate differs between feed rate and perfusion rate, especially for delicate processes such as cell perfusion, which have higher requirements for precision and flow stability. - Compatibility of the Peristaltic Pump Tubing Material with Culture Media, Additives, etc.
The solutions transported in bioreactors are mainly chemical liquids such as culture media and additives. Therefore, when selecting a peristaltic pump, it is necessary to consider the compatibility of the peristaltic pump tubing with these chemical liquids to avoid chemical reactions. Furthermore, some solutions are highly sensitive to cells, requiring the selection of a peristaltic pump with stable operation and minimal pulsation.
- Control method of peristaltic pump: The bioreactor system has high automated operation efficiency, which also increases the control requirements of the peristaltic pump. Peristaltic pumps with interfaces such as analog control and digital communication must be provided to enable remote control and data storage in conjunction with the bioreactor.
