Perfusion Bioreactor Technical Support

Technical information perhaps of interest


A fair amount of information has been released on the PerfuseCell website. Divided with detailed info under Products and comprehensive extra info under Support and Downloads. If you have further questions please contact us and we shall look into your requests.

The above photo show black (OD 144 x L 865 mm) SiliconCarbide carrier developed long time ago by Per Stobbe and the WORLD first one-piece giant Cross-Flow-Filter (CFF). By far better than the limited corrosion resistant yellow Cordierie carrrier seen in SS housing. Right side photo a range of scalable LASER controlled diaphragm Single-Use-Pump based on the CerPhragm design combined with Hollow-Fibre-Filters for pharma upstream continuous processes.

PerfuseCell's back-up group - developed in the 90ties entirely from scratch and patented the concept and manufacturing method of world largest one-piece 11 kilo heavy SiliconCarbide ceramic Cross-Flow-Filter carrier's (OD 144 x L 865 mm) with 13 m2 surface area supporting a 200 nm pore size membrane. Able to handle large broth volumes with a range of viscosity, particle sizes and dry mass. Unique with respect to retentate velocity, Trans-Membrane-Pressure, permeate pressure, fouling, selective separation, filter cake, deposits control, pore size, and much more.

Further Stobbe Group was faced with limitations in peristaltic hose pump performance. As well as limitations of traditional diaphragms pumps. The product development became the patented, LASER guided Clio Single-Use-Pump (O-SUP) and Thalia Single-Use-Pump (A-SUP) diaphragm technology both driven by the Clotho and Lachesis Drive Units. We named the diaphragm pump technology for CerPhragm™.
