Latest Patents
Fleming holds a patent for a cell culture bioreactor. This invention is particularly suitable for the culture of viable, shear-sensitive cells, whether grown in suspension or attached to substrates like microcarrier beads. The apparatus features a cell culture compartment and a compensation chamber that maintains sterile conditions while operating in a zero-headspace mode. It includes a gas exchange tube connected to an external gas source, creating both a downflow and a central upflow zone within the culture compartment. An Archimedean screw-type auger is installed to facilitate a circulating flow of liquid, while the design minimizes turbulence through upper and lower flow guide surfaces. The gas exchange tube is adept at enhancing gas exchange efficiency by interacting with both the outer and inner surfaces of the liquid inside the culture compartment.
