Abstract
A culture vessel for improving culture or cell yield of anchored cell or suspension cultures has a fluted body wall to provide the vessel with internal ribbing. The internal ribbing of the vessel increases the surface area available for anchorage-competent cell growth and also enhances the agitation of cells in suspension culture to disperse the cells and promote growth.
