Mixing device for mixing the content of a bioreactor, comprising a synchronization mechanism

A system comprising a mixing device for mixing of a bioreactor and a synchronization device,

• the mixing device comprising:
• at least one movement device for inducing a mixing motion to the bioreactor or to a holder of the bioreactor,
• at least one sensor attached to or in the bioreactor for recording at least one physiological or physical parameter,
• wherein the mixing device or the bioreactor further comprises a sensor for generating a synchronization readout, namely a trigger signal or a digital signal (on/off or high/low),
• wherein the synchronization readout is synchronized or synchronizable with the mixing motion induced to the bioreactor or to the holder thereof,
• wherein the synchronization device:
• a) triggers the measurement of at least one physiological or physical parameter on the basis of the synchronization readout or
• b) selects at least one recorded value of at least one physiological or physical parameter on the basis of the synchronization readout;
• and
• wherein the system uses a frequency spectrum for calculating and/or recording the physiological or physical parameter and/or physiological or physical parameter consists of a frequency spectrum, wherein the frequency spectrum is discretely and discontinuously recorded in dependency of the synchronization readout.
