Kühner AG, Birsefelden, Switzerland

ExcellGene SA and Kühner AG in a partnership with Sartorius-Stedim AG are presently developing the first disposable 2000 Liter scale OrbShake bioreactor It is expected that this bioreactor will be offered to the market late in 2009. Numerous studies, published or in the process of being published have shown that the OrbShake technology is equivalent and frequently superior in performance to classical stirred tank technology. ExcellGene and its' partners have filed a number of patents that cover the gained insights. In short, efficient mixing provides homogeneous conditions throughout the reactor while assuring very efficient oxygen transfer to cells even at high density. A 200 Liter OrbShake bioreactor will be offered to the international markets by May 2009 (ACHEMA 2009, Frankfurt). For further information, don't hesitate to contact TAnderlei@Kuhner.com.

Sartorius Stedim Biotech SA, Aubagne, France

Small scale helical track bioreactors (50 ml, 250 ml, depicted on the technologies menu) for high density animal cell culture in suspension invented by ExcellGene scientists in collaboration with the Laboratory of Cellular Biotechnology at the EPFL and developed in a partnership with Sartorius-Stedim AG, Göttingen. These products are sold under the name CultiFlask 50 plus and CultiFlask 250 by Sartorius-Stedim AG

TPP AG, Trasadingen, Switzerland

TPP develops, manufactures and distributes highest quality cell culture equipment, based on disposable plastic wares. TPP and ExcellGene have conjointly developed suspension cell culture containers with regulatable gas transfer caps (as seen on our front-page) that allow for efficient exchange of oxygen, carbon dioxide (and humidity). If required, any of the 5 openings in the cap can be sealed and the gas exchange trimmed to requirement. Sterility is maintained at all times by means of an additional filter membrane (0.22 micrometers). TPP intends to expand this offer for larger containers suitable for suspension cell cultures of volumes of up to 500 ml that allow for rapid centrifugation and thus cell free harvests from such cultures. TPP also markets the innovative biomass assessment tool, mentioned above as PCV-tubes (PCV= packed cell volume), that was originally developed at the laboratory of the founder of ExcellGene at the Swiss Federal Institute of Technology.
