摘要:
The present invention provides a novel method for culturing cells as well as a novel method for producing a recombinant protein by culturing cells at large scale (up to 1,500 L nominal volume and 750 L working volume), whereby an inflated bag provides a sterile, disposable cultivation chamber. The inflated bag is partially filled with liquid cultivation media and cells, and placed into a containment vessel. The containment vessel is positioned onto an orbitally shaken platform. The orbital shaking moves the containment vessel and thus the bag and induces thereby motion to the liquid contained therein (“shake mixing”). This motion (caused by orbital shaking) induces a dynamic force field that ensures cell suspension, bulk mixing, and oxygen transfer from the liquid surface to the respiring cells without damaging shear or foam generation.
摘要:
A multiple burner cooking assembly for portable cooking includes a table and a plurality of burners that is each of the burners is coupled to the table for having a cooking pot positioned thereon for cooking. A plurality of conduits is each of the conduits is coupled to the table and each of the conduits is fluidly coupled to a respective one of the burners. A plurality of valves is each fluidly coupled to a respective one of the conduits and each of the valves is in fluid communication with a respective one of the burners. A supply hose is fluidly coupled to the plurality of conduits and the supply hose is attachable to a fuel source to deliver the fuel in the fuel source to the conduits.
