Breez™ Bioreactor System (for bioprocess development)

The Breez™ bioreactor is the only mL-scale platform that offers fully automated, continuous True Perfusion™ cultures. Sterile, single-use 2mL microbioreactor cassettes with built-in sensor technology and fully integrated fluidics enable the control of critical parameters like temperature, dissolved oxygen, pH, optical density and a short turnaround time with reduced contamination risk.

Bubble and foam free gas transfer in the Erbi Breez™ is accomplished by gas diffusion through a silicone mixing membrane, with barely any shear stress on your precious cells. Low sample volume with a minimum of 50 µL and automated harvest from up to 4 parallel, but individually set bioreactors per platform allow not only a perfect setup for media optimization but also for N1-perfusion and mich more.

Achieve the maximum yield with the minimum commitment and financial input and begin your process development at an earlier stage = smaller volume in the Breez™ bioreactor. Contact us to "Meet the Breez™ ".
