Section 6 Delivery & Installation
6.1 Unpacking and Parts Check
Please pay attention to the following advice:
1.A.A.1. Carefully check the outer packaging, the packaging
of the single components, as well as the parts themselves
for damage.
Warning: Do not use culture vessel when damage is suspected.
In such a case, the glass vessel might burst during sterilization
in the autoclave.
1.A.A.2. Check if the delivery is complete. To prevent
scratching, please handle with care when using sharp
objects to unwrap the packaging.
1.A.A.3. Please use caution when loading or unloading to
prevent damage due to collision.
1.A.A.4. When moving or positioning the controller, take
care not to lift it by holding the peristaltic pump heads.
They are not designed to be used as handles, and can be
damaged by lifting a heavy load.
1.A.A.5. If parts are missing or damage occurs in transit,
please inform your local Major Science representative.
23

6.2 Installing the fermentation system, space requirements
2.A.A.1. The system will require an area of approximately W
x D = 1,500 x 600 mm (including the space for the culture
vessel and the cooling circulating water bath)
2.A.A.2. You may vary the arrangement of the components
according to the lengths of the connecting lines. It is
recommended to consider some additional space for
convenient handling of the equipment.
2.A.A.3. Use the (+) Screwdriver to open the back panel for
gas pressure adjustment before first use (Screwdriver is
provided in the standard package). Detailed instructions
are given below.
6.3 Utility Requirements
3.A.A.1. Gas Source: the incoming gas must be reduced to
at least 2 bar (29psi) before entering the air inlet (Fig. 1).
If you are using an air compressor or a cylinder, please be
sure to use an external regulator to reduce the gas
pressure. The inlet gas must be further adjusted to 0.5 bar
(approx. 7psi) using the built-in pressure gauge (Fig. 2),
the back panel must be opened for access). The built-in
pressure gauge will be fully shut off when the
fermentation system first arrives, which means no air flow
will be observed in the rotameter. Open the back panel
and lift up the pressure gauge knob to adjust. Turn
counterclockwise to open the pressure valve and turn
clockwise to close the pressure valve. After adjusting to
0.5 bar, push the knob down to lock and close the back
panel.

Fig. 1 Fig. 2
3.A.A.2. Coolant Source: Please make sure your water
quality is clean (50 micron filter). The hardness of water
should be below 12 German Degree of Hardness in order
to prevent calcareous deposits. The water pressure must
be reduced to 1 bar (14.5psi) to prevent damage to the
valve. To achieve a good cooling efficiency, we
recommend setting the coolant temp. at least 15 20 º C
below the desired culture temp. Using tap water is not
recommended but workable. Please tighten the main
water inlet connection to prevent leaking or bursting.
Damage caused by impure water quality will not be
covered by the warranty.
Suggested tubing size for coolant & air connection (Fittings might be needed
for connecting to your air & coolant source):
For chiller (Main water inlet & Main water outlet port): 3/8 (9.6mm)
For Air (Gas outlet, Air inlet & O2 inlet): 3/16 (4mm)

Note:
The condenser water flow is controlled by a condenser water flow regulator
(See figure below). The cooling coil water flow is controlled by a solenoid
valve. The solenoid valve opens only when the vessel requires cooling
function. When performing temp. control, the valve will open to let water flow
into the cooling coil. At the same time, you will also hear the sound of the
solenoid valve, which means the valve is functioning correctly.
In order to provide constant water flow through the condenser, we must turn
the regulator knob to open the regulator valve halfway. The purpose is to
prevent media evaporation. The condenser helps evaporated media re-
condense back to liquid.

4.D. DO cascade Setting
4.D.A.1. DO (Dissolved Oxygen) Cascade
Our DO cascade program is specifically designed to meet most of your
experimental needs when running a fermentation/bio-reaction experiment.
DO control usually does not come online until bacteria/yeast starts to grow
exponentially, which consumes tremendous oxygen in a short period of
time.
So the purpose of the DO Cascade program is to maintain the DO level
within the system once the DO set point value has dropped to a significant

level which may affect the result of the experiment. If DO level never
reaches the set value, the DO cascade program will not initiate hence it
will not be activated.
For example, if your DO set point (SV) is set at 40% and the present value
(PV) is 65%, DO cascade will not activate since PV has not dropped below
40%. No action will be taken by the DO Cascade program because it has
not been triggered or activated.
4.D.A.2. DO Set point
DO set point acts as an activator for the DO cascade program (as
explained in the previous section) and also acts as a control point for your
DO level.
This is the set value you require for the DO level during your experiment.
For example, DO level is set at 40.0%, which means when DO Cascade is
triggered, it will maintain DO level at 40.0%.
This setting here allows you to add substrates through your pump feeding
when DO level drops below the set value (e.g. 40.0%). You could select
the feeding pump you assigned on (using the pump setting). Once the
feeding program is triggered, it will run to completion.
4.D.A.3. Setting Menu
51

The DO Cascade setting menu is located under the Setting page. Its
feature can be divided into two sections: Control Strategy and Feeding
Strategy.
Control Strategy (1):
Settings in the black box, this strategy accommodates majority of the user
needs. These settings allow you to adjust DO level using Agitation, O2
enrichment module, O2 with mass flow controller enrichment or Gas
Mixing Station.
Feeding Strategy (2):
52
Settings in the red box, this is commonly used for any user who wants to
harvest secondary metabolites during the experiment or needs to activate
a feeding program at a specific DO condition. Hence with the First Trigger
and Second Trigger options, whereas Second Trigger will not activate

unless First Trigger condition has been met and is true. Details of this
strategy are explained on page 7.
4.D.A.4. Control Strategy
After setting your DO value, lets continue to the right side of the screen,
you should see there are 2 stages available for your DO control. When DO
Cascade is in motion, the program will run stage 1 first, if stage 1 method
fails to maintain the DO level, the system will proceed to stage 2.
Selecting the right method to use:
By pressing the rectangular button, you could select which specific method
you prefer to run for each stage.
Different Methods and related input values:
b.1 Stirr
Select this to use agitation to increase or decrease your DO
level
53

54
Time (sec): duration of each cycle
Step (rpm): this is the rpm value for each increment or
decrement during each cycle
Max (rpm): this is the maximum rpm value for this stirring
method
Min (rpm): this is the minimum rpm value for this stirring
method
b.2 Built-in O2
b.3 Built-in O2
b.4 O2 (GM)
Select this when connecting with MS O2 enrichment module
(FS-O-OE). The cycle duration will follow your O2 setting from
the Maintenance page (please see page 9 for the O2 setting).
All values here are irrelevant.
Select this when connecting with MS Oxygen enrichment with
mass flow controller (FS-O-MF)
Time (sec): the calculation cycle of each time interval for the
increment/decrement, sampling time
Step (%): the % of the increment/decrement of the total time
interval, T1 (which could be adjusted in the
maintenance page)
Max (%): the maximum amount of time for the solenoid
valve to be opened
Min (%): the minimum amount of time for the solenoid valve
to be opened
Select this when connecting with MS Gas Mixing Station (FS-
O-GM) and would like to adjust DO level using O2 only.
Time (sec): the calculation cycle of each time interval for the
increment/decrement
Step (%): the % of the increment/decrement of the total time
interval, T1 (which could be adjusted in the

maintenance page)
Max (%): the maximum amount of time for the solenoid
valve to be opened
Min (%): the minimum amount of time for the solenoid valve
to be opened
b.5 O2/N2 (GM): (FS-O-GM)
Select this when connecting with MS Gas Mixing Station (FS-
O-GM) and would like to adjust DO level using O2 for
increasing DO and N2 for decreasing DO.
Time (sec): the calculation cycle of each time interval for the
increment/decrement
Step (%): the % of the increment/decrement of the total time
interval, T1 (which could be adjusted in the
maintenance page)
Max (%): the maximum amount of time for the solenoid
valve to be opened
Min (%): the minimum amount of time for the solenoid valve
to be opened
Operating procedure using Control Strategy
The control strategy allows you to maintain your DO using the two
methods of your choice.
For the setting given above, stage 1 is using the Stirr method and stage
2 is using the Built-in O2 method. Once the DO level drops below 40%,
55

56
DO Cascade will activate the Stirr method by increasing the agitation
speed by 20 rpm per cycle. If the current setting is 200, for every 5
seconds, it will increase 20 rpm to 220 rpm, and check the DO level
again, if another increment is required, it will increase another 20 rpm
to 240 by the next 5 seconds, and if the system reaches your set max
RPM value (in this case, 500 rpm) and still unable to adjust the DO
level to 40%, it will proceed to Stage 2.
For Stage 2, as the example given below, this setting is using the Built-
in O2 enrichment module, as previous stated, if you have purchased
Gas Mixing station, Oxygen enrichment with mass flow controller, or
simply the oxygen enrichment module, you need to select it
appropriately in order for the setting to work properly.
c.1 Flow chart of increasing DO

c.2 Flow chart of decreasing DO
4.D.A.5. Feeding Strategy
Once your DO level falls/reaches your set value (First Trigger value, in %),
it will activate your second Trigger Value, once the DO raises up to the set
value, the feeding schedule (by selecting the Feed you want) will initiate.
The feeding strategy is designed for experienced user who understands
his experience thoroughly and would like to schedule a feeding schedule
based on the metabolic process of his bacteria such as lactobacillus. This
feature allows you to add substrates feeding based on the changes of the
DO level.
Operating procedure using Feeding Strategy (red box)
57

58
As the setting given above, when the DO level drops from 40% to 20%,
it will active the first trigger, which is still in idle mode but waiting for the
second trigger value to be active. Once the DO level rises from 20% to
50%, if a feeding schedule is selected, it will be activate.
Note: if DO level rise directly from 40% to 50%, it will not activate the
feeding strategy because the first trigger value (20%) was not reached.
4.D.A.6. Finding your T1 (total time interval)
Go to Maintenance page, on this page you should be able to locate the
total time interval for the oxygen valve. (for FS-O-OE and FS-O-MF)

T1 = the cycle duration in time for the oxygen valve
T2 = the duration in time the valve will open during each cycle.
Note: when selecting your O2 source, these values (values in blue box
from the picture below) will not apply to O2 enrichment module. Instead,
Cascade will only use the pulse interval of the oxygen cycle (T1 and T2 in
red box from the picture above) to adjust your DO level. All values are
irrelevant.
59

60
Example: In the settings given below:
Once the first stage of the DO cascade has failed to maintain the dissolved
oxygen level, the system will automatically enters the second stage and
introduce pure oxygen to raise the DO value. Make sure to have the
Oxygen selection set to ON in order to have this feature to work properly.
In this case, the Oxygen valve will open every 10 seconds, with increment
of 1 second (10% of 10 seconds [T1] = 1 second) with maximum opening
valve time as 10 seconds (100% of 10 seconds [T1] = 10 seconds) and
minimum opening valve time as 1 second (10% of 10 seconds [T1] = 1
second).
So the system will start with opening valve for 1 second, and close for 9
seconds, if it failed to maintain the DO level, it will proceed with opening
valve for 2 second (1 second initial with increment of 1 second), and close
for 8 seconds, and so on.
For every 10 seconds (Time), the system will monitor the DO level to
calculate the increment or decrement of the solenoid valve.

4.D.A.7. The Restore Delay
The minimum duration in time (only in digits, not decimal points) for which
the system will evaluate before it de-activate the program. (This is to make
sure DO level reaches the set point and is stabilized)
4.D.A.8. The Response dead-band value
As our systems standard value, the response dead-band is 5 %. This
value is the neutral buffer area where no action occurs. The purpose of the
response dead-band value is to prevent oscillation or repeated activation-
deactivation cycles of DO cascade, which may cause great fluctuation of
the DO level and shorten the life of the solenoid valve. This means that if
your DO set point is at 40%, the DO cascade program will not initiate and
until the DO level reaches 35% (40 % - 5% [dead-band value]); vice-versa
the program will sustain in the idle when the DO level reaches 45% (40% +
5% [dead-band value]).
Note: Response dead-band could be adjusted according to your need,
61

minimum setting is 1.5 %.

9.2 Prepare the Culture Vessel and Accessories
2.A. Check the Equipment
While installing the culture vessel and fitting the probes and accessories,
carefully check all parts for damage. Pay special attention to any potential
cracks in the glass vessel, split in the O-rings (especially the one on the
bottom of the head-plate), and any possible harm done to the seals on the
rotating shaft.
82
Warning:

2.A.A.1. When a damaged glass vessel no longer has the
bursting strength required for sterilization in the autoclave
or running fermentation, it must be replaced immediately.
2.A.A.2. Damage to the seal can cause contamination of the
culture during the fermentation process. Seals-on
accessories which are often removed and refitted should
be replaced regularly.
2.B. Vessel assembly and head-plate arrangements
2.B.A.1. Unscrew the screws on top of the head-plate and
remove the head-plate.
2.B.A.2. Attach all parts (not including tubing) meant to be
mounted onto the head-plate:
2.B.A.3. O-ring seal: make sure the O-ring is properly fitted
onto the bottom of the headplate
2.B.A.4. Any port where there are no accessories part
attached must be fitted with a blind port to prevent
leakage.
2.B.A.5. If an O-ring is damaged, it must be replaced. You
may grease the O-rings (especially the one between
glass vessel and headplate) with silicon grease to prevent
the O-ring from deforming over time and to stop air from
escaping from the vessel.
2.C. Set up the air supply
2.C.A.1. Attach two pieces of silicon tubing to either side of
a 0.2 micron air filter (provided). Make sure the tubing
lengths are long enough to reach from the controller to
the vessel. Use clamps to close the tubing on each side
of the filter.
83

84
2.C.A.2. Secure one end onto the To air sparger port on the
vessel and the other onto the Gas out port on the
controller
2.C.A.3. With a storage bottle, connect one port with silicon
tubing to the exhaust port on the top of the condenser.
2.C.A.4. Connect the other port to a filter (an exhaust filter)
with a short piece of silicon tubing.
2.D. Set up the feeding port
2.D.A.1. Fill the 250 ml storage bottles with acid, base,
antifoam reagent, or nutrient.
2.D.A.2. Connect them each with silicon tubing to the
feeding ports on the head-plate. The tubing should be of

Section 11 Cleaning and Maintenance
11.1 Vessel Cleaning
1.A.A.1. Fill the vessel with a mild detergent and water
solution
1.A.A.2. Let the solution stand for 1 hour, and then scrub
thoroughly with a soft brush. A toothbrush may be used
for smaller parts and hard to reach areas
1.A.A.3. Drain, and rinse several times with tap water
1.A.A.4. Rinse a final time with distilled water, and allow to
dry
11.2 Control Station Cleaning
The control station can simply be cleaned by wiping with a damp cloth or
towel
11.3 DO electrode information and maintenance
Please follow the instructions below to maintain your D.O. Probe:
3.A. Cleaning the probe
One effective way to remove contamination from the cathode surface is to
wash it with a toothbrush and toothpaste. Then rinse with D.I. Water.
3.B. D.O. sensor malfunction
10 probable causes of D.O. sensor malfunction are listed below:
106

3.B.A.1. Punctured membrane
3.B.A.2. Torn or ripple membrane
3.B.A.3. Dirty cathode
3.B.A.4. Dirty or fouled anode surface
3.B.A.5. Damaged O-ring
3.B.A.6. Missing O-ring
3.B.A.7. Damaged cathode
3.B.A.8. Dirty membrane
3.B.A.9. Corroded connector
3.B.A.10. Electrolyte level too low
Reference: Summer 1998 Broadley-James corporation
3.C. Testing the D.O. Sensor membrane
One simple way to test the membrane puncture is to connect the membrane
cartridge with a syringe using an adapter. Monitor the bubble formation during
pumping (See figure). Bubble formation may indicate leakage of the
membrane.
107

3.D. Membrane replacement and electrolyte refill
3.D.A.1. Keep the sensor in an upright orientation, then
unscrew the old membrane cap.
3.D.A.2. Remove the membrane, expose the glass body in
the air.
3.D.A.3. Clean the tip of the glass body with a soft tissue.
3.D.A.4. Gently introduce 1.5 ml DO solution into the new
membrane cap.
3.D.A.5. Carefully screw the new membrane cap onto the
sensor shaft.
How to replace the DO solution
108

3.E. Membrane kit
3.E.A.1. DO solution, 20ml
3.E.A.2. Spare O-rings
3.E.A.3. Pipette
3.E.A.4. Polishing strip
3.E.A.5. Membrane cartridge
3.F. Storage and electrolyte replacement
The DO probe can be stored in 3M Potassium Chloride solution. The DO
solution is used for inner cartridge electrolyte replacement. After using the
probe a few times, you can check the solution condition by nude eye (check if
there is precipitation or color change). If precipitation or color change occurs,
please replace with new solution.
11.4 pH probe information and maintenance
Please follow the instructions below for your pH electrodes maintenance:
109

4.A. Cleaning the measuring electrode
4.A.A.1. Remove any deposits from the membrane or
diaphragm by rinsing the electrode with mild detergents.
4.A.A.2. For calcium deposit, soak the electrode in a 0.1M
HCl solution for a few minutes.
4.A.A.3. For proteins, soak the electrode in a solution of 1%
pepsin and 0.1M HCl for several hours.
4.A.A.4. Inorganic coatings can be removed using
commercially available glass cleaning solution (e.g.,
Windex).
4.A.A.5. Silver sulphide deposits, caused by the reaction of
sulphides containing solution with silver chlorides in most
electrodes, can be removed by soaking the electrode in a
0.1 M thiourea/HCl solution until the diaphragm is totally
bleached.
4.A.A.6. To remove highly resistant deposits, hydrogen
peroxide or sodium hypochlorite is recommended.
4.A.A.7. Rinsing the electrodes in a 0.1M HCl or 0.1M
NaOH solution for a few minutes may be able to remove
the acid or alkaline soluble deposits.
4.B. After cleaning
After the cleaning process, soak the TrupH electrode in the storage solution
(3M KCl) for 12 to 24 hours. Cleaning solution may penetrate the diaphragm
during cleaning. It is necessary to calibrate the pH measurement after the
hydration process.
110

4.C. Storage of the electrode
For long-term storage, immerse the pH electrode in a 3M KCl solution.
4.D. Aging
Aging is unavoidable. However, proper maintenance can delay the process.
Typical symptoms of an aged measuring electrode includes:
4.D.A.1. Increased response time
4.D.A.2. Increased membrane resistance
4.D.A.3. Declining slope, especially in the alkaline region
4.D.A.4. Shift of the asymmetry potential (zero point shift)
Lifetime of each electrode depends on the operating and handling conditions.
The electrodes have a maximum operating lifespan of 18 months if handled
properly. The lifetime may only last 2 months if operated at the temperatures
exceeding 90°C. The electrode stops working after only 2 weeks when
exposed to strong base (pH > 13) and high temperature (> 90°C).
In most cases, we will find that pH electrodes age gradually. An increased
response time is the most direct indication of aging. If the response time
becomes unacceptable for your fermentation process control, we recommend
replacing the pH electrode with a new one.
4.E. Storage solution
To prevent dehydration of the probe, we recommend storing the probe in the
3M Potassium Chloride solution every time after use.
