Fully equipped bioreactor and control

EDF-5.4 is an autoclavable glass bioreactor with working volume till 4,5l (total volume 6,2 l, inside diameter 150 mm).

Laboratory bioreactor EDF-5.4 has two versions:

  • EDF5.4_1 for the cultivation of bacteria, yeasts and mycelial cultures;
  • EDF-5.4_2 for the cultivation of mammalian and plant cells.


EDF-5.4 has a compact, ergonomic and robust design. Glass cylinder vessel is mounted between the upper lid and the metallic jacketed bottom. The design of the bioreactor is easy to maintain and apply basic operations and preparatory process, in particular,
washing and autoclaving.

5L bioreactor SCADA interface

Extension and option possibilities

Gas mixing using mass flow controllers Hamilton ARC pH and DO sensors. These sensors send 4-20 mA signals directly to PLC and ensure at the same time information management via Bluetooth in smartphones or PC installed programs. This program generates a report about all calibration procedures, sterilization numbers, predicted service life.

Connection of additional sensors: culture turbidity (optical density), culture permittivity (viable cell density), conductivity, methanol/ethanol, off-gas analysis (O2, CO2, CH4), etc.

On-line/off-line data analysis and advanced process control possibilities using PC implemented program (Matlab, Python) algorithms communicating to process control system (PLC and SCADA).
