Mini Bioreactors: Real Small, Real bioreactors


The range of bioreactors (250 ml, 500 ml and 1000 ml total volume) is a true scale down of the laboratory scale bioreactors in the 1 to 15 liter range. The systems have the same flexibility as the laboratory scale bioreactors. This means that the systems can be customized to fit the demands of any process. The small volume reduces medium costs and reduces the use expensive bench space.
Functions  of mini bioreactors:

  • Generate more data in less time
  • Easy setup and operation
  • Cultivate using less medium
  • Cultivate using les bench space
  • Generate scalable results
  • Mimic lab scale bioreactors
  • Easy data handling


Controller is a dedicated control system for the small scale bioreactors. One control system can control:

  • 250 ml up to  1000 ml bioreactors
  • 1l up to 3 liter Autoclavable bioreactors
  • 3 liter single use bioreactors


  • PID and autotuning adaptive control
  • Operation via webbrowser , iPod, iPhone or iPad
  • 1 up to 32 parallel my-Controllers  per network
  • Integrated amplifiers for agitation, pH, DO, Temperature, Level and foam
  • Actuators for up to 6 variable speed pumps or micro valve additions, up to 4 Mass Flow Controllers, Heating and Cooling (via Peltier or heating blanket),condenser cooling (Peltier or cooling water)
  • Spare I/O:  8 x digital output,  4 x analog in (0 - 10 V), 4 x analog out (0/4 - 20 mA)
  • USB connection for Biomass or Fluorophor pH and DO
