    • An apparatus and method for culturing cells includes a waste removal and product concentrating loop in which waste is removed from the medium and product produced by the cells is concentrated for harvesting. The apparatus includes a reservoir for retaining a supply of medium. The reservoir is in fluid communication with a cell culturing loop wherein medium flows from the reservoir to the cells and back to the reservoir. The medium waste removal and concentrating loop removes waste components produced by the cells and is in fluid communication with the reservoir such that medium is transferred from the reservoir to the waste removal and concentrating loop and back to the reservoir. The waste removal and concentrating loop includes a device having a semipermeable membrane. The medium flows along one side of the membrane for selective transfer of the waste components through the membrane. A mechanism for selectively producing a back pressure in the medium is included downstream of the membrane and aids in transfer of waste components through the membrane to remove the waste components from the medium.
    • 用于培养细胞的装置和方法包括废物去除和产物浓缩环,其中废物从培养基中除去,并且由细胞产生的产物被浓缩用于收获。 该装置包括用于保持介质供应的储存器。 储存器与细胞培养环流体连通,其中介质从储存器流动到细胞并返回储存器。 中等废物去除和浓缩循环去除了由细胞产生的废物组分,并且与储存器流体连通,使得介质从储存器转移到废物移除和浓缩环并返回储存器。 废物去除和浓缩回路包括具有半透膜的装置。 介质沿膜的一侧流动,以便通过膜选择性地转移废物组分。 用于选择性地产生介质中的背压的机构包括在膜的下游,并且有助于废物组分通过膜的转移以从介质中除去废组分。
