EDF-1.2 is innovative twin bioreactor, designed for both research and process development in fermentation and cell culture.

Our twin bioreactor has compact and ergonomic design. Temperature control of the bioreactor vessel is made by innovative temperature control system, equipped with a Peltier element. Consequently, the temperature control is provided without connecting the vessel to the bioreactor cooling water source. Magnetically coupled drive creates good sterility conditions.
