Actually, it is my understanding that what was once in development has now been commercialized in the form of the “Breez” bioreactor from erbi. It is a cassette-based mL scale bioreactor platform enabled with mixing and closed loop pH, DO, Temperature CO2 and Cell Density. I have not had first-hand experience with it yet but people I trust who are affiliated with the platform have good things to say. Use the link below to learn more;
