The CultiFlask 50 disposable bioreactor is a versatile tool to perform media optimization/process development experiments in high numbers.

It resembles the classic 50 ml centrifuge tube design, thus making handling steps like e.g. media exchange very convenient. Each bioreactor is equipped with a vented screw cap with five holes of different size for optimal gas exchange with the surrounding atmosphere; a PTFE membrane serves as a sterile barrier and minimizes liquid loss by evaporation.
