Say goodbye to lengthy downtime with super-fast turnarounds.

CellMaker 1 CellMaker 2

The specially designed CellMaker airlift single-use bioreactors have been created to perfectly suit our system and your application. These single-use bags are easily replaced within minutes for a fast turnaround so you can start on your next process.

These sterile bags are fitted into the enclosure and the contents are agitated by bubbles created by a customizable influx of gasses. 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 agitated mixing impellers. Single use disposable mixing bags are available in sizes 8 Liters and 50 Liters to suit your enclosure, and provide working volumes of 3L to 8L, and 10L to 50L.

Our CellMaker Regular Bioreactors are compatible for use with our CellMaker Regular Controller and CellMaker Plus Controller. While our CellMaker Plus Bioreactors are designed for use with our CellMaker Plus Controller only. 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.
