  • Publication number: 20230323271
    Abstract: A sterile foam breaking system, (14, 42, 52) includes a foam collector (20) having an opening (26), configured to be disposed in a source (12) which generates foam. The sterile foam breaking system (14, 42, 52) further includes a non-coated type suction unit (23) coupled to the foam collector (20). The non-contact type suction unit (23) is configured to transfer the foam via the opening (26) of the foam collector (20) and break a portion of the foam to generate a first quantity of liquid droplets. The sterile foam breaking system (14, 42, 52) additionally includes a foam breaking unit (28, 44, 54) coupled to the non-contact type suction unit (23). The foam breaking unit (28, 44, 54) is configured to receive remaining portion of the foam and the first quantity of liquid droplets and break the remaining portion of the foam to generate a second quantity of liquid droplets.

  • Publication number: 20220403318
    Abstract: The present subject matter discloses a bioreactor apparatus. The bioreactor apparatus comprises a bioreactor vessel configured to culture cells. The bioreactor apparatus furthermore comprises a sensor configured to measure Dissolved Oxygen (DO) in the bioreactor vessel. The DO measurements comprise a plurality of DO values recorded at, at least, a plurality of time instances during operation of the bioreactor apparatus. The bioreactor apparatus furthermore comprises a controller configured to obtain the DO measurements. The controller furthermore is to determine, in real-time or approximately real-time, an oxygen mass transfer co-efficient (kLa) associated with the operation of the bioreactor apparatus. Furthermore, the controller is configured to control, in real-time or approximately real-time, at least one cell culture parameter associated with the operation of the bioreactor apparatus based on the kLa.
