Vessel for growth of biological entities

A vessel for culturing cells comprising:

• a vessel main body defined by a bottom having a rounded edge that is integral with a conically-shaped sidewall that tapers inward to a top surface;
• two or more interior baffles configured to disrupt a liquid vortex of a liquid media contained within the vessel during agitation of the liquid media;
• and
• an integral elongate annular neck extending upwardly from the top surface to a vessel opening, wherein
• the neck is joined to the vessel main body via a tapered transition area, and
• wherein the baffles extend along the conically-shaped sidewall, along the rounded edge to the bottom, and radially inward along the bottom, the baffles each comprising a v-shaped cross-section defined by sidewalls separated by an angle of 80° to 110°, and wherein the baffles extend radially inward from and downward from the rounded edge to the bottom of the vessel at an angle between 5° and 30°.
