ABSTRACT:
A suspension cell culture system where a culture chamber is rotatable about a horizontal axis and has a vertical large area oxygen transmissible membrane spaced a distance about 0.25 inches less than 1.0 inches from a facing vertical wall surface for effective transmission of oxygen to cells in suspension in the culture chamber. The facing vertical wall surface can be a dialysis membrane for exchange of fresh nutrient from a dialysis chamber with cell waste product in the culture chamber.
