Flexible bioprocessing vessel and rigid support structure

A hexagonal flexible bioprocessing vessel comprising:

• six flexible panels forming sides of the hexagonal flexible bioprocessing vessel;
• a top panel adjoining the six flexible panels, the top panel forming a top of the hexagonal flexible bioprocessing vessel;
• a bottom panel adjoining the six flexible panels, the bottom panel located on an opposite end of the hexagonal flexible bioprocessing vessel from the top panel, and forming a bottom of the hexagonal flexible bioprocessing vessel, the six flexible panels, top surface, and bottom panel defining an interior cavity configured for processing a fluid;
• and
• at least one fluid input and at least one fluid output for adding and removing fluid to and from the interior cavity of the hexagonal flexible bioprocessing vessel respectively;
• wherein hexagonal flexible bioprocessing vessel has a liquid level height to width ratio of 1.
