The WAVE Bioreactor systems are available in several different configurations allowing control of some or all of these key parameters. The parameters can be controlled by instrument modules integrated into the WAVE Bioreactor and/or by external instrument modules, that is, WAVEPOD (available with different functionalities) and standalone modules. For examples of how control of different parameters can be achieved, see Table 1-1. Note that more than one external instrument module can be used with a WAVE Bioreactor base unit to get access to more control functions. For some parameters, several control options are available. For example, pH in the culture medium can be controlled by: • • On-line control of pH by pH measurement and pH adjustment by acid and base additions. This requires: • WAVEPOD with pH control module and PUMP20, or • the external instrument modules pH20 and PUMP20. Indirect control of pH by control of the CO2 concentration. This requires: • Integrated CO2 control module (as in BASE20/50EHT-CO2), or • WAVEPOD with CO2 control module, or • the external instrument modules CO2MIX20 or CO2MIX20-R.

General recommendations For stable pH control it is necessary to cycle the addition pumps so that the acid or base has sufficient time to mix properly. The pH20 controller has a cycle time of a preset duration (default= 30 seconds). Part of this cycle is the on time when the acid or base pump is energized. For the remainder of the cycle the pumps are off and the controller waits until the cycle time is complete. 90 WAVE Bioreactor 2/10 and 20/50 systems Operating Instructions 28-9641-23 AA Control systems 4 External instrument module control systems 4.4 • If, at the end of the cycle, the pH is still not at the setpoint, the controller initiates another add/wait cycle. • If the pH is at the setpoint, the controller does nothing. A small deadband around the setpoint (default = 0.1 pH) is used to prevent excessive pump chatter. The cycle time can be adjusted if the system requires more mixing time. The amount of acid or base added per cycle is proportional to the difference between the setpoint and the actual pH. The Gain constant adjusts the sensitivity. This Gain can be decreased if insufficient acid or base is being added per cycle. It can also be increased if very concentrated acid or base is being used and significant overshoot is observed. Connecting the base pump Step Action 1 Turn the power switch on (I). The power switch is located on the back of the instrument module. Make sure that the BASE ENBL button is off. 2 A peristaltic base pump such as the WAVE PUMP20 can be controlled by the pH20 controller. If using PUMP20 units, plug the PUMP20 for the base pump to the Controller using the supplied cables. 3 Make sure that the pump direction is correct and turn all local switches on. Route the base tubing through the pump and connect to the Cellbag container. Open all valves. 4 Set the desired pH setpoint on the controller and press the BASE ENBL button to activate base control. 5 The base pump turns on whenever the pH drops 0.1 unit below the pH setpoint.

However, cell population and metabolism determines the necessary rocking rate for oxygen transfer. • Measuring dissolved oxygen is the best way to determine the required rocking rate. This may be done by off-line or on-line measurement. See Section 5.3.4. Aeration rate recommendations • Aeration rate (through the inlet air filter) has little effect on oxygen transfer. Aeration rates should be kept to a minimum to reduce evaporation. • Aeration rate may be adjusted to change the pCO2 or pH. Recommendations to reduce foaming • Foaming can be reduced by lowering the rocking angle. • Typical rock angle is 6 to 8 degrees. • For very foamy medium, the rock angle should be reduced to 4 to 5 degrees. • For cells with high oxygen demand, such as insect cells, the rock angle can be increased to 10 degrees. • If extensive amount of foam is generated reduce the rocking speed. Note however that is critical that the rocking speed be sufficient to generate a visible surface wave. • It is usual practice to add 0.01 mg/liter of pluronic F-68 to the culture medium to minimize protein degradation associated with the effects of foaming. Most commercial cell culture media already contains pluronic. Excessive foaming also occurs if the Cellbag is not rigidly inflated. Check that you have sufficient airflow and that the pressure relief valve is functioning Set operating conditions Set operating conditions for rocking and aeration and optionally for dissolved oxygen measurement, control of pH, CO2 and O2 using the control systems for the system and external instrument modules used.

Note: Small inoculum volumes may be added by syringe through the sampling port. 4 Restart the rocking motion. 5.3.4 Start culturing For instructions to monitor and set operating conditions for the current system configuration, see relevant parts of Chapter 4 Control systems‚ on page 49. Note: Ensure that the Cellbag is rigidly inflated at all times when rocking. An underinflated bag may crack and leak. The Cellbag upper surface should be drum-tight. WAVE Bioreactor 2/10 and 20/50 systems Operating Instructions 28-9641-23 AA 103 5 5.3 Operation Performing a run Note: Issues with the systems or set culturing conditions are acknowledged by an alarm. An new alarm is indicated by a flashing ALARM button in the main screen of the Touch screen. The Touch screen color also changes to red and an audible beeper sounds. See Chapter 4 Control systems‚ on page 49 for handling Alarms. Step Action 1 Make sure that desired operating conditions are set, see Operating conditions recommendations‚ on page 100. 2 • It is possible to adjust rocking rate, rocking angle, aeration, and temperature, • For some system configurations it is also possible to monitor and/or control dissolved oxygen, pH, CO2 concentration, O2 concentration and conditions for performing perfusion culturing. Start rocking, aeration and other desired monitor and/or control functions. 5.3.5 Culture options Sampling the Cellbag Samples may be taken at least 50 times using the same sampling connector without any danger of compromising sterility. The sample is also completely contained as no aerosols are vented. 104 Step Action 1 Adjust the rocking rate if required. At low rocking rates (<15 rpm) it is sometimes difficult to get a representative samples due to settling. In this situation, the recommended technique is to raise the rocking rate to 15 rpm 5 to 10 minutes prior to sampling. The rocking speed can be lowered after sampling. 2 Remove the dust cap from the sampling connector (see Section 1.6 for a Cellbag description). WAVE Bioreactor 2/10 and 20/50 systems Operating Instructions 28-9641-23 AA Operation 5 Performing a run 5.3 Step Action 3 Wipe the top of the sampling connector with 70% alcohol (or equivalent). 4 Using aseptic technique, attach a sterile disposable syringe onto the connector. 5 Release the tubing clamp and withdraw a sample into the syringe. You may need to push down on the Cellbag to force the liquid up the sample tube. 6 Remove the syringe and wipe the top of the sampling connector again with 70% ethanol and replace the dust cap. 7 Pinch the sampling connector tubing a few times to ensure that any liquid in the tubing drains back into the Cellbag. 8 Close the tubing clamp. Note: A standard syringe or luer connector may be used without a needle. Note: The sampling device has a fairly small orifice. If you are working with large microcarriers or large cell aggregates do not use the sampling connector. WAVE Bioreactor 2/10 and 20/50 systems Operating Instructions 28-9641-23 AA 105 5 5.3 Operation Performing a run Dissolved oxygen measurement and control WARNING Heavy object. Filled Cellbags have a considerable weight and heavy lifts must be done with care. Use 1 person per multiple of 15 kg weight, for example 3 persons for 30 to 45 kg. All lifting and moving must be performed in accordance with local regulations. The WAVE system is designed to provide an excess of oxygen for most culture systems. To ensure desired levels of dissolved oxygen it is important to measure the levels of dissolved oxygen and adjust the dissolved oxygen concentration if required. Step Action 1 To measure the dissolved oxygen level: 2 • Off-line dissolved oxygen measurement can be made by taking samples by syringe (see Sampling the Cellbag‚ on page 104) and quickly determining the pO2 concentration using a blood-gas analyzer. • On-line dissolved oxygen measurement can be done using the microthin flexible optical DO probe. The DO probe fits into the Oxywell2 sheath built into each Cellbag and can be inserted and removed repeatedly for calibration without compromising sterility. To adjust dissolved oxygen concentration: • Using an integrated instrument module or an external instrument modules which can provide any desired O2 concentration. • To increase dissolved oxygen concentration, increase the rocking speed. Note: Dissolved CO2 concentrations are influenced in the inverse manner as dissolved oxygen. pH control pH control can be achieved by: 106 • use of pH control module (WAVEPOD or standalone unit), which enables on-line control of pH in the Cellbag. • indirect control by control of the CO2 concentration (CO2 Control module, integrated, WAVEPOD or standalone unit). • use of appropriate buffers. WAVE Bioreactor 2/10 and 20/50 systems Operating Instructions 28-9641-23 AA Operation 5 Performing a run 5.3 Scaling up culturing WARNING Heavy object. Filled Cellbags have a considerable weight and heavy lifts must be done with care. Use 1 person per multiple of 15 kg weight, for example 3 persons for 30 to 45 kg. All lifting and moving must be performed in accordance with local regulations. Cellbags have a large range in operating volume. This allows an inoculum scaleup and eliminates tedious sequential transfers. Start at low volume and add fresh medium to the Cellbag as the cells grow. Up to a 1:10 expansion is possible in a single chamber. A typical inoculum sequence is: Step Action 1 Start with 100 mL medium in 2L Cellbag. Add inoculum. 2 When cells reach 2 × 10 cells/mL, add 300 mL medium to the Cellbag. 3 When cells again reach 2 × 10 cells/mL, add more medium to bring the volume to 1 liter. 4 When these cells reach 2 × 10 cells/mL, transfer using a tube-fuser to a 20L Cellbag containing 2 liters of medium. 5 When the cells in the 20L Cellbag again reach 2 × 10 cells/mL, bring the volume to 10 liters and continue cultivation at full volume. 6 6 6 6 In this sequence, only one transfer was made in going from 100 mL to 10 liters of culture. This saves time and reduces the risk of contamination. This scheme can also be used to scale-up inoculum for larger conventional bioreactors. Culture medium exchange WARNING Heavy object. Filled Cellbags have a considerable weight and heavy lifts must be done with care. Use 1 person per multiple of 15 kg weight, for example 3 persons for 30 to 45 kg. All lifting and moving must be performed in accordance with local regulations. For instructions to monitor and set operating conditions for the current system configuration, see relevant parts of Chapter 4 Control systems‚ on page 49. WAVE Bioreactor 2/10 and 20/50 systems Operating Instructions 28-9641-23 AA 107 5 5.3 Operation Performing a run Note: To avoid possible oxygen depletion, the culture medium exchange operation should be performed in less than one hour.

Error symptom Possible cause Corrective action The display shows a CO2 concentration in air which deviates from the expected value (0.0%). A minor deviation from the expected value is not unusual. The tolerance of the CO2 sensor is ±0.38% in the range 0% to 7.5% CO2. If the reading is not within the tolerance, the CO2 offset can be adjusted, see WAVE Bioreactor Instrumentation Manual. CO2 reading keeps drifting down The CO2 gas supply pressure is too low Check that the green CO2 inlet pressure light is lit. The CO2 supply pressure must between 10 and 15 psig. CO2MIX20 and CO2MIX20-R 134 WAVE Bioreactor 2/10 and 20/50 systems Operating Instructions 28-9641-23 AA Troubleshooting 7 External instrument modules 7.4 Error symptom Possible cause Corrective action Faulty CO2 control The CO2 supply is not properly connected Verify that CO2 is connected to the correct inlet port. Check that the air pump is on and that the flow rate is between 0.1 and 0.5 liters/minute. Check that the CO2 switch is on. Wrong setpoint set Check the setpoint on the controller. Obstructed airflow Check that airflow to the Cellbag is not obstructed. Verify that the pump is working by disconnecting the MIX OUT coupling on the instrument. No air flow Verify that there is airflow to the Cellbag. Faulty check valve Check that the check valve on the Cellbag is correctly installed. Close off the Cellbag outlet using the pinch clamp and see if the Cellbag inflates. Then confirm that the check valve is working by connecting a short length of tubing to the check valve outlet and dip it into water. Tubing should be immersed to a depth of 5 to 10 mm. Opening the outlet pinch valve should cause bubbles to appear and bubbles should continue to flow as the flow and pressure stabilizes. Error symptom Possible cause Corrective action The display shows a O2 concentration in air which deviates from the expected value (21.0%). A minor deviation from the expected value is not unusual. The tolerance of the O2 sensor is ±0.6% in the range 21% to 40% O2. If the reading is not within the tolerance, the O2 offset can be adjusted, see WAVE Bioreactor Instrumentation Manual.
