Disposable Bioreactor

Superspinner D 1000 from Sartorius Stedim Biotech is a fully disposable and ready-to-use bioreactor for seed and lab scale protein production. It is a pre-assembled and ready-to-use bioreactor for efficient lab scale cultivation of cells. Main feature is a membrane stirrer, which allows controlled and gentle mixing, bubble free aeration and avoids foam generation. The gassing membrane ensures higher oxygen transfer and thus ­optimal growth conditions and high cell densities. The bioreactor consists of a cultivation flask and a membrane aeration system that also functions as a stirrer. A hollow-fibre membrane is wound around the stirrer bar which contains a magnetic core driven by a magnetic drive unit. A membrane gas pump feeds ambient air through a sterile filter into the flask. The whole set-up is placed in an incubator.
