Complete your system with our specially designed CellMaker Plus Bioreactor Bags. These bags contain a sensor for measuring dissolved oxygen and a pH port making these bags ideal for providing precise control over more challenging processes. They are easily replaced within minutes for a fast turnaround so you can start on your next process. Our robust system is designed without any moving parts, eliminating the chance of mechanical failure. In addition, gentle agitation from our bubbles reduces the risk of cell shearing usually associated with impellers. The 4L Plus Bioreactor Bags offer working volumes from 1.5L to 4L and are compatible with our CellMaker Plus 8L system.
