Multi Channel Bioreactor RTS-8

RTS-8 uses the patented ReverseSpin® technology. This is an innovative and energy-saving stirring technique that results in highly efficient mixing and oxygen supply for aerobic cultivation.
By rotating the Falcontubes around their own axis and changing the direction of rotation, the cell suspension is optimally mixed.

In combination with near-infrared optics, it is possible to measure the kinetics of cell growth non-invasively in real time.

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).
