The UniVessel® SU is a disposable stirred bioreactor. The bioreactor was a new development. The focus was on increased usability and better operability. In addition, the disposable container was replaced. Functionally, the single-use bioreactor is comparable to the autoclavable glass bioreactors. The main advantage is that the complete container can be disposed of after use. This shortens cleaning times and reduces the risk of contamination.
