1L Laboratory scale bioreactor

1L fermentation bioreactor

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


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


Peltier element cooled condensers provide exceptional exhaust gas cooling without the usage of circulation water. Robust construction and fan-driven heat exchange develop enough power to cool and condense even high-temperature processes.

Easily exchangeable, large 1L glass vessels provide the option to use multiple vessels with the same lid providing flexibility in day to day operations and easing in research production.

Novel magnetic drive coupling eliminates the need for a mechanical seal and can provide mixing rate from 40 rpm to 2000 rpm.

Powerful Peltier element provides possibilities for cooling and heating temperature maintenance from 10-60℃

Uniform top lid with no welded components for improved sterility and ease of maintenance. The vessel is equipped with all the necessary sensors and ports for a successful fermentation process.
