1 Predilute Operation
The Predilute operation (Figure 1-12) allows the starting cell product to be diluted
as necessary with processing/wash solution. To prevent fluid from entering the cell
processing bag, the clear tubing is clamped between the rotating seal and the
junction manifold. The cell product bag is placed on the tabletop. Pressing the
PREDILUTE button opens valve V2, allowing processing/wash solution to flow
into the cell product bag.
See the following table for a summary of the Predilute operation.
