Multi-channel bioreactor RTS-8

Bioreactor with real time biomass, pH and pO2 measurement

RTS-8 is a personal bioreactor that utilizes patented ReverseSpin® technology that applies non-invasive, mechanically driven, low energy consumption, innovative type of agitation where cell suspension is mixed by the single use falcon bioreactor tube rotation around its axis with a change of direction of rotation motion resulting in highly efficient mixing and oxygenation for aerobic cultivation. Combined with a near-infrared optical system it is possible to register cell growth kinetics non-invasively in real time.

Features of multi-channel bioreactors

  • Parallel cultivation enables to save time and resources for bioprocess optimization
  • Individually controlled bioreactor accelerates optimization process
  • Possibility to cultivate microaerophilic and obligate anaerobic microorganisms (not strict anaerobic conditi ons)
  • Reverse–Spin® mixing principle enables non-invasive biomass measurement in real time
  • Near-infrared optical system makes it possible to register cell growth kinetics
  • Free of charge soft ware for storage, demonstration and analysis of data in real time
  • Compact design with low profile and small footprint for personal application
  • Temperature control for bioprocess applications
  • Active cooling for rapid temperature control, e.g. for temperature fluctuation experiments
  • Task profiling for process automatization
  • Cloud data storage to remotely monitor the process of cultivation while at home or using a mobile phones

Software RTS-8

  • Connect up to 12 units (recommended) simultaneously to 1 computer
  • Remote monitoring option (requires internet connection)
  • Cycling/Profiling options
  • User manual calibration possibility for most cells

Benefits RTS-8

RTS mixing principle has a number of advantages, e.g. automatic balancing, defoaming single-use, etc., but one of the more important points is that, due to the individual rotation principle and thermostating of each bioreactor tube, different conditions for supporting the temperature (from 4 to 70°C) and aeration conditions can be applied (from anaerobic to aerobic).
