• RTS-1C Personal Bioreactor with Cooling

    The Grant-bio RTS-1C is personal bioreactor with cooling which provides “Reverse-Spin” type of agitation and logging of microbial growth in 50 ml tubes in real time.

    RTS-1C including TubeSpin® Bioreactor 50, TPP®, 20 pcs.


    • Innovative mixing due to reverse spinning of the sample around its own axis
    • Due to innovative mixing technology it is possible to measure optical density of the probe in real time
    • Software has been developed to store, display and analyse the data in real time
    • Compact device with low profile and small footprint for personal application
    • Temperature control allows use as an incubator, e.g. for cell growth
    • Active cooling and temperature profiling via software
    • The ability to change parameters such as temperature, RPM and “Reverse-Spin” frequency, allows to achieve consistency and reproducibility of results
    • Programmable Cycling/profiling of cultivation parameters such as temperature, RPM, “Reverse-Spin” frequency
    • The ability to remotely monitor the process of cultivation while home or using a mobile phone
