BS-010160-A03 | Single position bioreactor for the non-invasive monitoring of cell growth in real-time with a temperature control range of 15°C below ambient to +70°C (RTS-1C)

Key Features

  • Patented Reverse-Spin® technology non-invasively optimises mixing and oxygenation for aerobic cell cultivation
  • Near-infrared optical system accurately determines OD levels to monitor cell growth kinetics
  • Utilises 50 mL Falcon tubes with membrane filters to provide a working media volume of 10 mL - 30 mL
  • Temperature control range from 15°C below ambient to +70°C
  • Active cooling for rapid temperature control
  • Real-time cell growth logging
  • Software included for storage, demonstration and analysis of data in real-time
  • Up to 10 RTS-1C units can be simultaneously controlled by a PC through the software


The RTS-1C is a single position bioreactor that utilises patented Reverse-Spin® technology to non-invasively optimise mixing and oxygenation for aerobic cell cultivation. With this novel technology a cell suspension in a single use 50 mL Falcon tube with a membrane filter is rotated around its axis in alternating directions to achieve a mass transfer coefficient (kLa (h-1)) of up to 450. This level of mass transfer is ideal for efficient aerobic cell culture.

The RTS-1C features a near-infrared optical system that uses a NIR light diode emitting at 850 nm. Highly accurate measurements of OD can be taken from 1 - 60 times per hour to provide a profile of cell growth in real-time. The temperature control range for the RTS-1C is 15°C below ambient to +70°C.

Key applications for the RTS-1C include:

  • Fermentation real time growth kinetics
  • Clone candidate screening
  • Protein expression
  • Temperature stress and fluctuation experiments
  • Media screening and optimisation
  • Growth characterisation
  • Inhibition and toxicity tests
  • Strain quality control
