Load Cells With Uniform Suspension
The purpose of this task is to load the cells into the bioreactor from the cell inlet bag until the bag is
empty and to use IC circulation to create uniform cell suspension. This task includes three separate steps:
•
Step 1: loads the cells into the bioreactor.
Note: One method for determining the volume in the cell inlet bag (step 1) is to use a volume that is an integer
multiple of the IC Inlet Rate.
• Step 2: chases the cells from the ARC into the IC circulation loop.
• Step 3: circulates the cells to create uniform cell suspension.
Table 10-10 describes the types of solution that are needed to attach to each line when performing Load
Cells With Uniform Suspension. These solutions and corresponding volumes are based on the factory
default settings for this task.
As a precondition before starting this task:
Fill the cell inlet bag with a minimum of approximately 40 mL of air.

Confirm the settings for step 1 shown in Table 10-11.
Table 10-11: Step 1 Settings for Load Cells With Uniform Suspension
Setting Factory Default Setting Options
IC Inlet Cell N/A
IC Inlet Rate 25 mL/min 20 to 100 mL/min
IC Circulation Rate 150 mL/min 30 to 300 mL/min
The system automatically calculates this rate based on the IC Inlet Rate
for this step.
