2.1 System overview
Introduction
Xuri Cell Expansion System W25 is intended for cell cultivation.
A disposable Cellbag bioreactor is placed on a rocker and filled with gas, partially filled
with culture medium, and inoculated with cells. Gas transfer and mixing of culture is
accomplished by wave-induced agitation, performed by the rocker unit.
The cell culture volume range per Cellbag bioreactor is 0.3 to 25 L depending on
bioreactor size, and working volume may be expanded up to 10 times during one culti-
vation.
The system, composed of the rocker, Xuri Cell Expansion W25 CBCU and Xuri Cell
Expansion W25 Pump , enables measurement and control of pH, DO, weight and media
distribution, and provides different gas flow and gas mixing possibilities.
•In single mode , the system supports culture in one Cellbag bioreactor at one time.
The rocker is connected to one Xuri Cell Expansion W25 CBCU and up to three Xuri
Cell Expansion W25 Pump units.
•In dual mode , the system supports culture in two Cellbag bioreactors placed on
the same tray. The rocker is connected to up to two Xuri Cell Expansion W25 CBCU
units and up to three Xuri Cell Expansion W25 Pump units for independent control
of culture conditions in the two bioreactors.
The system is controlled from a PC running UNICORN software version 7 or later. The
system can also be controlled from a supervisory control and data acquisition (SCADA)
system, such as the DeltaV™ control system, using the integrated OPC server. Contact
Cytiva for instructions and guidance for OPC.

Illustration of the system
The illustration below shows the main system units for use in single mode with one Xuri
Cell Expansion W25 Pump . Dual mode uses two Xuri Cell Expansion W25 CBCU units
for controlling the two Cellbag bioreactors independently. Both single and dual modes
can support up to three Xuri Cell Expansion W25 Pump units.

Stage Description
1 Inflowing gas from the CBCU enters the Cellbag bioreactor through the
inlet vent filter. The gas flow inflates the bag and oxygenates the culture.
2 Metabolic waste gases leave the Cellbag bioreactor through the outlet
vent filter. The pressure control valve maintains a constant overpressure
inside the Cellbag bioreactor.
3 The rocking mechanism sets the rocking platform in motion.
4 Wave motions are induced by the rocking. The culture is cautiously
mixed, and gases are transferred into the culture.

Available controlled parameters
The table below describes the controlled parameters for the fully configured bioreactor
system. The controlled parameters of your configuration may vary from the list below.
In dual mode, all parameters except rocking speed, angle and motion may be
controlled independently in the two Cellbag bioreactors.
Parameter Description
Temperature The system can control temperature between room temperature
plus 5°Cand 40°C.
Rocking
speed
Rocking speed can be set between 2 and 40 rpm.
Rocking
angle
Rocking angle can be set between 2 and 12 degrees.
Rocking
motion
Rocking motion can be set between 15% and 100%, and is by
default set to 30%. A rocking motion of 15% gives a uniform
motion with almost constant angular velocity throughout the
movement, and 100% gives a smooth, completely sinusoidal
motion.
Gas flow The system can control the gas flow into the cellbag between 0.02
and 1.00 lpm.
Media
distribution
The system can control culture medium addition and removal.
Two different modes exist, media addition and perfusion.
pH pH is measured and controlled between pH 6 and pH 8. Three
different modes of pH regulation exist, with CO2, CO2/base, and
acid/base.
DO DO is measured between 0% and 250% and controlled between
0% and 100% air saturation. Three different modes of DO regula-
tion exist, with O2, speed, and O2/speed.
CO2CO2 concentration in gas mix can be controlled between 0% and
15% and measured between 0% and 20%.
O2O2 concentration in gas mix can be measured between 0% and
50%, and controlled between 0%and 50% with N2 and between
21% and 50% with air.
2 System description
2.1 System overview
Xuri Cell Expansion System W25 User Manual 29064622 AD 15

2.2 Xuri Cell Expansion System W25 rocker
Introduction
The rocker is the main unit of the system. Through the rocker, weight is measured, and
temperature, rocking speed, rocking angle and rocking motion are controlled.
The rocker contains four load cells for monitoring the weight of the Cellbag bioreactor
and content. The placement of the load cells allows independent weight measurement
of the two Cellbag bioreactors in dual mode.
The rocker also contains an embedded microprocessor, which allows the system to be
controlled independently of the performance of the connected network and client
computer.
For rocker specifications, see Rocker specifications, on page 244.
Rocking parameters
The adjustable rocking parameters are rocking speed, rocking angle and rocking
motion. These factors, in combination with the cell culture volume, have a direct
impact on the oxygen transfer rate and mixing time in the Cellbag bioreactor.
The rocking motion sets how large part of the rocking cycle that has a sinusoidal
angular velocity. It can be adjusted to be more or less sinusoidal. The minimum value,
15%, gives a uniform motion with almost constant angular velocity throughout the
movement, resulting in a step-wise rocking. The maximum value, 100%, gives a sinus-
oidal motion with slower angular velocity in the end positions and faster in the middle
of the movement, resulting in a smoother rocking.
