Hybrid Approaches with Stainless-Steel and Single-Use Systems

Stainless steel boasts a long history in biopharma manufacturing, but single-use systems offer reduced cleaning and validation – and are gaining ground fast. Many companies are reaping the unique benefits of both by implementing hybrid approaches.

To build a stainless-steel plant and then implement some single-use systems for certain processes to make them more efficient or cost effective. Tofflon can provide the hybrid solution for building familiarity and confidence in single-use systems while maintaining production capacity.

Single Use Bioreactor

•        Low upfront CAPEX and fast setup

•        Highly flexible and rapid cGMP modular designs

•        No CIP/SIP and minimal process cleanroom areas and waste liquid handling required

•        50 L to 2000 L systems available using Thermofisher, Sartorius, and GE’s Single Use Bioreactor bags

•        Integrated bioreactor controllers to ensure the unity of control at all production stages

•        With flexible control signal interface to integrate the cell culture data from electrodes, exhaust gas analyzer, glucose sensor and other analytical analyzers

Stainless Steel Bioreactor:

•        Changeable mixing components can adapt to process needs

•        Magnetic stirring - scalable, sterile, and affordable maintenance

•        Automatic one-key operations, CIP/SIP/, inoculating/feeding, reduce the operation and training difficulty of personnel

•        Current manufacturing scale can reach 500kL
