The cuboid geometry maximises volume per footprint, provides stability in large-volume holders, and is the standard format for single-use bioreactor systems above 100 L.<\/p>\n<\/div>\n<h2>3D bags in single-use bioreactors<\/h2>\n<p>In single-use stirred-tank bioreactor systems, the 3D cuboid bag is the disposable inner biocontainer \u2014 holding the cell culture and discarded after each batch, eliminating CIP\/SIP for the vessel interior. The bag fits inside a rigid outer support housing providing mechanical stability during agitation.<\/p>\n<h2>Scale-up with 3D bags<\/h2>\n<p>Typical scale-up: 100 L pilot \u2192 200 L clinical \u2192 500\u20131,000 L commercial. Each scale requires a bag validated for that bioreactor platform \u2014 bag geometry, port placement and sparger specifications are platform-specific.
