eProd Bioreactor SU
Single use double purpose Bioreactor
eProd Bioreactor SU is a stirred tank reactor with a single-use bag (eBAG 3D STR), designed for cell culture and microbial fermentation processes at 300 L and 1000 L scales. It combines a stainless steel vessel with a jacket for thermal control, mechanical agitation and an automation system geared towards operation and traceability.


eProd Bioreactor
Industrial stirred-tank bioreactor for microbial and cell culture processes, with automation, CIP/SIP and plant-ready integration.
The eProd bioreactor is an industrial stainless steel bioreactor platform for upstream production, designed for both microbial fermentation and cell culture processes. It is available in working volumes from 100 to 2000 L and integrates vessel, agitation, thermal control, gas distribution, instrumentation and automation in a compact system for industrial and GMP environments. Depending on the process configuration, the platform adapts geometry, impellers and aeration strategy while maintaining a consistent control architecture with PLC, HMI/eSCADA and OPC integration

Ranges in NL/min (normal conditions). In microbial processes, N₂ and CO₂ may be used in advanced pO₂ and pH strategies depending on configuration. In cell culture, CO₂ is commonly used for pH control depending on the selected strategy.
- MFC calibration: factory calibrated.
- Operating range: from ±2% of selected full scale to the maximum of the MFC range.
- Accuracy: ±(1% of measured value + 0.5% FS).
- Maximum working pressure: 6 barg.
- Sterile gas filtration: 0.2 µm cartridge at inlet.

kLa values are indicative estimates under reference conditions (water/air, 1 atm, high operating point) and should be used as a commercial guide. For guaranteed values by size and configuration, request a performance report.
- Microbial mode (MB): the recommended vvm window is indicative for stable operation and may vary depending on process strategy.
- Cell culture mode (CC): lower shear operation is prioritised, with repeatable pH and DO control depending on gas and agitation settings.
- OTR optimisation: microspargers, pressure increase and O₂ enrichment can significantly improve oxygen transfer in microbial processes.
- Process confirmation: final productivity (titre, g/L, growth rate) depends on strain/cell line and the customer process.
