the top ports in the center of the flattened bag, so the tubing and hardware do
not snag or catch during filling (Figure 31).
NOTE:
A correctly installed Allegro 3D biocontainer system will have a gap of
approximately 20 – 25 mm between the system and the walls of the tote to allow
for movement and expansion of the single-use system as it forms during filling.
