Stainless Steel Suspension Cell Culture Bioreactor



Duoning provides customized bioreactors with volume of >20 L for suspension cell culture, as well as supporting systems such as liquid mixing, inactivation and emulsification. In addition, we can provide customers with process design, pipeline construction, system integration, bioreactor design and manufacturing, control software development and other services.

 

System features

Ÿ   These systems can be used for suspension culture, microcarrier culture for monoclonal antibody, vaccine or protein-based therapeutics production, to achieve multiple use in one tank.

Ÿ   Suspension and microcarrier culture using propulsion impeller or lifting impeller, low shear force, short mixing time, good mixing effect

Ÿ   Deep microbubble direct air supply/bubble-free air supply device provide good oxygen transfer, meets the requirements of high-density cell culture, and reduces the damage to cells

Ÿ   Using jacket and tank dual temperature PID control, temperature control is stable and accurate

Ÿ   Sterilization-in-place sampling/sampling valve group to ensure safe, reliable and convenient operation

Ÿ   Air intake/exhaust filter sterilization can be carried out independently to meet the requirements of filter replacement during the culture process

Ÿ   CO2/O2/AIR flow rate adopts thermal mass flow controller, to realize the automatic feedback control of gas flow rate

Ÿ   Dissolved oxygen control can adopt AIR/O2 or AIR/O2/N2 mode. The DO control adopts unique PID control logic for stable and accurate control

Ÿ   Deep sparger and overlay air supply adopt different control methods in sterilization process, to ensure thorough sterilization and no dead end

Ÿ   Deep sparger uses a combination of hardware and software, effectively eliminate culture fluid reflux

Ÿ   PH control adopts time judgment to avoid the simultaneous addition of CO2 and base

Ÿ   Peristaltic pump control allows external mobile peristaltic pump, easy to replace

Ÿ   Pipeline and frame adopt open design, easy to use and maintain

Ÿ   Pipeline adopts 3A standard, comply with GMP and BPE requirements

Ÿ   Connection seal of the mixing impeller in the tank effectively avoids dead end and is easy to clean

Ÿ   Pipeline construction is carried out in cleanroom to ensure welding quality

Ÿ   Material inlet and tank bottom valves can be sterilized separately

Ÿ   All the pipelines and tee connections on the tank body meet 3D requirements

Ÿ   Dual mechanical seal, sterilization-in-place; or bottom magnetic stirring

Ÿ   The control system adopts PLC control

Ÿ   Servo motor, large torque, realizes stable and reliable work

Ÿ   Powerful software functions, such as parameter setting, display control, test parameter, curve analysis, data storage, and output printing

Ÿ   System adopts electronic signature, which meets the requirements of GMP audit
