Claim:
A container for cell growth by artificial cultivation of selected biological material in a growth liquid for use in an oscillating incubator, comprising: the container having a circular bottom with rounded corners joining a sidewall that is inclined at an angle toward a longitudinal axis of the container to define a usable container volume, the bottom having a diameter with six equally spaced baffles extending inward from the corners toward the longitudinal axis and upward toward a large diameter opening of the container centered on the longitudinal axis, the baffles having a triangular cross-sectional shape with an apex having an included angle of about 28–40°, and a height measured parallel to the longitudinal axis of about 15–25% of the usable container volume, the baffles ending before the longitudinal axis but extending to within a distance from that axis that is at least about 1/6 the diameter of the bottom, the container and baffles being blow molded of a polymer suitable for blow molding.
