Single-use bioreactor approaches for constructing single-use bioreactors, differing in the means used to agitate the culture medium. Some single-use bioreactors use stirrers like conventional bioreactors, but with stirrers that are integrated into the plastic bag. The closed bag and the stirrer are pre-sterilized. In use the bag is mounted in the bioreactor and the stirrer is connected to a driver mechanically or magnetically. Other single-use bioreactors are agitated by a rocking motion. This type of bioreactor does not need any mechanical agitators inside the single-use bag.. Both the stirred and the rocking motion single-use bioreactors are used up to a scale of
