G-Rex® closed-system bioreactors:
Predictable, scalable cell expansion

G-Rex is the only cell culture bioreactor equipped to meet current and future patient demand for immune cell therapies. G-Rex was designed for predictable, efficient, and scalable cell expansion. It enables parallel patient processing and can produce the large numbers of cells needed for cell-based therapeutics, from preclinical through commercial scale manufacturing.
G-Rex is ushering in a new era of simplicity for cell therapy manufacturing. By giving cells unlimited and undisturbed access to nutrients and oxygen, G-Rex bioreactors eliminate media exchanges and the complex and expensive hardware required in integrated systems.

Linear and predictable cell expansion in G-Rex bioreactors means a streamlined path to the clinic. Using G-Rex, the preclinical protocol and cell quality you develop directly transfers up into a large-scale closed-system process. In doing so you eliminate unnecessary process changes that often plague scale-up into complex bioreactors.
