• a support column positioned within the cell culture chamber that extends between the top wall and the bottom wall;
• a stabilizer device comprising a pair of outboard wings and a central wing disposed within the cell culture chamber, wherein the central wing is disposed between the pair of outboard wings and the pair of outboard wings are pivotally coupled to the pair of side walls, the central wing including column engaging structure that is sized to slidingly engage the support column;
• wherein the support column guides the central wing along a height of the support column as the central wing is raised.
