Mini Bioreactor RTS-1

RTS-1 logs germ growth in 50 ml tubes in real time. Thanks to the innovative mixing technology, it is possible to measure the optical density of the sample non-invasively in real time.

Graphical 3D display of optical density and growth rate.

Typical applications:

  • Bacterial cultivation with real time growth kinetics
  • Strain screening
  • Temperature stress and fluctuation experiments
  • Media screening and optimization
  • Synthetic and systems biology
  • Inhibition and toxicity tests
  • Strain quality control

RTS-1 Mini-Bioreactor

  • Reverse-Spin® mixing principle in 50 ml falcon tubes allows to achieve high kLa (h-1) up to 450 which is essential for efficient aerobic cultivation
  • Innovative mixing thanks to rotation of the sample in the opposite direction around its own axis
  • Reverse-Spin® mixing principle enables non-invasive biomass measurement in real time
    (see the Reverse-Spin® Technology; Innovative Principle of Microbial Cultivation in the download section)
  • Software: display of data in real time, analysis and storage of data
  • Temperature control allows the RTS-1 to be used as an incubator, e.g. for cell growth
  • The possibility of changing certain parameters, such as temperature, revolutions/minute and spinning time in one direction
  • Enables constant and repeatable results to be achieved
  • Cycle/analyze cultivation parameters such as temperature, agitation parameters - such as temperature, agitation, change of rotation direction - after reaching a certain time or certain OD values
  • Possibility of remote monitoring of the cultivation process


Software features:

  • Real–Time cell growth logging
  • 3D graphical representation of OD or growth rate over time over unit
  • Pause option
  • Save/Load option
  • Report option: PDF and Excel
  • Connect up to 10 units simultaneously
  • Remote monitoring option (requires internet connection)
  • Cycling/Profiling options
  • User calibration options for most cells
