The VerSus Reactor is a new and innovative BioReactor for animal cell culture in which the technology of “SPG membrane sparger*” by which micro-bubbles with extremely high homogeneity can be generated is fused with a VMF reactor. Through an efficient oxygen supply by the SPG membrane sparger, oxygen can be supplied efficiently without putting stress on the animal cells in the culture tank. Also, due to a decline in the DO air flow rate, a foam layer can be prevented. With the help of the dedicated controller “S-BOX × 10α II”, changes in various parameters including PI control can be easily performed.

*SPG membrane sparger has been developed jointly by MIYAZAKI PREFECTURE INDUSTRIAL TECHNOLOGY CENTER and JGC Corporation.
