Gas mixing and gassing
Gas mixing system
The gas mixing system integrated in the DASbox is fully mass flow controlled and supports software configurable gassing schemes.
It has 4 gas inlets as well as 4 device channels, each of which can be assigned to a bioreactor.
The gas inlets are supplied by default with N2, Air, O2 and CO2. Each device channel is equipped with two
outlets for submerged or overlay gassing (see below "Integrated splitter function").
4 x 4 independently operating mass flow controllers for each gas and each channel allow for continuous
mixing of individual gas compositions.
Variants
For different applications the DASbox Gas Mixing System is available in two versions:
• Microbiology: 0 .. 30 sl/h (for CO2 max. 18 sl/h*)
• Cell culture: 0 .. 5 sl/h (for CO2 max. 3.5 sl/h*)
• *Due to the physical properties of the gas, the same maximum flow rates cannot be guaranteed for CO2 as for the other gases with which the DASbox Gas Mixing System is operated.
• The accuracy of flow values can not be guaranteed above the maximum flow rates.
• Nonreturn valves are integrated inside the device on the gas output side. They prevent
medium from flowing back into the interior of the device.
Integrated splitter function
The DASbox Gas Mixing System features a splitter function.
For each channel it can be determined which of the connected input gases should be directed through proportional valves to one of the two output channels ("Overlay" or Submerged"). Defining the supply of gas
types either to the headspace of the bioreactor or directly into the medium is thus possible.
The assignment of the gas types to the gas outlets is defined via the DASGIP Control software.
Find more information in the User Manual DASGIP Control.
Hardware and operation

5.1.2
Temperature control
The DASbox is equipped with a quick and accurate temperature control for each individual bioreactor.
It operates in a range of 10 – 60°C (at an ambient temperature of 25°C).
Pt 100 temperature sensors (class A RTD) ensure high temperature measurement accuracy.
The cooling system is completely free of liquid. An additional supply of coolant is not required.
Find more information in chapter 6.2.2 and in the User Manual DASGIP Control.
5.1.3
Agitation
The highly accurate DASbox agitation control enables a working range of between 20 and 2500 rpm.
For single-use vessels, the upper speed limit is 2000 rpm.
In DASbox Systems for cell culture applications, the maximal permissible speed is limited to 500 rpm
within the DASGIP Control software.
Depending on the type of application, DASbox Bioreactors are equipped with Rushton type impellers or
Marine type respectively pitched blade impellers.
The glass reactors have miniaturized industry standard lip seal assemblies.
The impellers are driven by brushless overhead drives offering long service life and minimal operating
noise.
Support for online calculation of the stirrer torque provides feedback on culture viscosity.
Notice! Risk of damage to overhead drive.
The overhead drives are not waterproof.
Do not immerse the overhead drives in liquid.

Deicing the off-gas condensers - Deice function
DASbox Off-Gas Condensers always operate at maximum cooling capacity. Longer periods of operation
may result in condensate freezing on cooled components.
If this happens, the temperature control actuator can no longer be detached from the condenser adapter
plate.
A setting in the DASGIP Control software therefore ensures that the operation of the Peltier elements is
automatically briefly reversed after each process is completed. For five minutes the off-gas condenser is not
cooled but heated in order to facilitate the disassembly of the temperature control actuator.
The DASGIP Control software also provides the "Deice" function by means of which the off-gas condenser
can also be heated during a process run for five minutes.
As soon as the actuator is separated from the adapter plate, the control switches back to standby mode.
Cooling operation starts again as soon as the actuator and the adapter plate are brought together again or
after the short heating period has elapsed.
Starting the "Deice" function
During the process run, click on the symbol for
temperature control T Controller in the process view of the
software.
The window containing the temperature control
parameters is opened.
Activate the Deice function by clicking on the Deice button.
The actuator briefly switches from cooling to heating

Addition of media - the MP8-pHpO module
The DASbox MP8-pHpO Module combines the functions of the DASGIP MP8 Multi Pump Module and the
DASGIP pHpO Sensor Module in a single device. This chapter describes the main functions of the
MP8 multi pump module.
Eight electronic speed-controlled feed pumps ensure the supply of DASbox Bioreactors with liquid media.
In standard process configurations, two feeding lines are thus available per bioreactor which enable the
continuous addition of nutrients and optimal pH control.
By using different pump tube types, a wide range of different feeding rates from 0 to 420 ml/h are possible.
The integrated calibration of the individual pumps ensures reproducible results.
5.3.1
Feed tubing and feed ranges
DASbox Feed Tubing
DASbox Feed Tubing consists of three individual parts:
The connection line between the reservoir bottle and the pump is connected via a flexible piece of tubing
(pump head tubing) to the connecting line between the pump and the bioreactor.

Pump head tubing
For the operation of the DASbox in standard applications, pump head tubing with an inner diameter of
0.5 mm is used. With this type of tube, a feeding range of 1.3 - 39 ml/h is possible.
Depending on requirements, other ranges can be covered by varying the pump head tubing used.
For information on standard tube types and the corresponding feeding ranges, refer to Fig. 5-4 and the
associated table 5-1.
Fig. 5-4:
Typical feeding rates (F in mL/h) for different pump head tubing diameters (ID in mm)
The table shows the minimum and maximum feeding rates that can be achieved belonging to pump head
tubing as well as the typical calibration factor FCal.
The calibration factor FCal is defined as the number of pump head revolutions per milliliter of the fed
medium. The exact value of the factor is determined during the calibration of the pump head tubing.

Continuous and pulsed feeding operation
Continuous feeding operation
The area limited by the minimum and maximum feeding rates in Fig. 5-4 shows the operating range which
allows a continuous feeding operation of the multi pumps.
• Continuous feeding operation is indicated by the pump
LED remaining constantly lit:
Green: clockwise rotation
Orange: counterclockwise rotation
Pulsed feeding operation
As soon as the values for the minimum possible feeding rates drop below the set-points, the pump switches
to a pulsed operating mode. In this mode, longer periods of pump inactivity alternate with feeding operation phases.
• In this operating mode, the pump LED only remains lit as
long as the pump is rotating.
• When the pump is stationary, a short flashing in longer
intervals indicates that the pump is active and is in the
standing phase of the pulsed feeding operating mode.
For further clarification of this principle of operation, refer to the typical working ranges of the pumps in
the table below.

CAUTION! Risk of damage to pumps by exceeding the upper speed limit!
The upper speed limit of the typical pump operating range (60%) must not be permanently
exceeded. Permanently exceeding the limit will reduce the service life of the tubing and drive.
Use pump head tubing with a larger inner diameter.
If the pump is operated permanently in the minimum speed region within an application, we
recommend the use of pump head tubing with a smaller inner diameter.
This allows feeding accuracy to be improved.

Calibrating pump head tubing
To be able to operate the pumps with defined feeding rates, the pump head tubing must first be calibrated.
The DASGIP Control software is used for calibration:
During this process, each of the theoretical feeding amounts per time unit are compared with the actual
feeding amounts within a preconfigured feeding program, taking into account the density of each media.
In addition, a calibration factor FCal [1/ml] is determined, i.e., the number of pump head revolutions per
milliliter of the fed medium.
For more information, refer to the User Manual DASGIP Control. It describes in detail how to carry out
the calibration procedure.
5.3.5
Sterilizing feed tubing
DASbox Feed Tubing in microbiology applications is usually sterilized using a cleaning-in-place (CIP) procedure. PTFE supply lines are used in most cases.
In cell culture applications, the supply lines are usually autoclaved for sterilization.
For this reason, C-Flex® supply lines are used.
CIP (cleaning-in-place) procedure
The sequential application of ethanol and sodium hydroxide is described in literature as an effective sterilization method, which also exhibits a deactivating effect on spores.
(Source: P. Girot, Y. Moroux, X.P. Duteil, C. Nguyen, E. Boschetti; Composite affinity sorbents and their
cleaning in place; Journal of chromatography, (1990) 510 213-223.)
The DASGIP Control software contains a preconfigured CIP procedure:
During this process, the feed tubing is successively rinsed with ethanol (70%) and sodium hydroxide (2 N).
This CIP procedure can be customized as needed.
Refer to the User Manual DASGIP Control. This manual describes in detail how to carry out the CIP
procedure.
NOTICE! Limited chemical resistance of C-Flex® tubing!
C-Flex® tubing is not suitable for use with alcohols and organic solvents.
Do not carry out CIP procedures on this type of feed tubing. Autoclave the supply lines
instead.
Hardware and operation
DASbox® Mini Bioreactor System

Autoclaving
You can also remove C-Flex® feed tubing from the mini pumps for autoclaving.
This practice is especially standard in cell culture applications:
Autoclave the feed tubing individually or connected with the reservoir bottles for media.
Seal the ends of the supply lines, e.g., with the corresponding Luer caps or aluminum foil.
CAUTION! Risk of product damage to feed tubing from autoclaving!
Only autoclave thoroughly rinsed feed tubing.
Media residues can crystallize in the supply lines and cause them to become irreversibly
blocked.
Do not sterilize PTFE feed tubing by autoclaving.
PTFE feed tubing is not resistant to autoclaving.
Do not seal feed tubing made of C-Flex® with a hose clip for autoclaving. The C-Flex®
material may become irreparably deformed.

Monitoring - the MP8-pHpO module
The MP8 - pHpO module combines the functions of a DASGIP MP8 Multi Pump Module and a pHpO sensor
module in a single device. This chapter contains important information on the functions of the sensor module and the associated sensors.
The pHpO sensor module supports the use of standard pH and DO sensors for the measurement and control of process values.
A separate input for a Pt100 temperature sensor allows for automatic temperature compensation during
calibration and measurement.
In addition, the control of conductivity sensors for level control or as an anti foam probe is supported.
As an alternative to the level option, a redox measurement is offered.
CAUTION! Risk of sensor damage from improper handling.
The sensors supplied with the DASbox are sensitive wet-chemical systems that require proper
handling, good care and regular maintenance.
Make sure to observe the manufacturer's instructions for the respective sensor types.
Please follow the instructions and information in this chapter and in chapter 7.3.
5.4.1
Sterilizing sensors
Please observe the following information:
• The DASbox sensors which are in direct contact with the culture medium can generally be sterilized by
autoclaving.
Before using alternative sterilization methods, please observe the instructions of the respective sensor
manufacturer.
• All Pt100 temperature sensors and the DO sensors for use with single-use bioreactors are not autoclavable.
• The sensors used in DASbox Glass Reactors are generally integrated in the bioreactor and autoclaved
along with it.
• The calibration of pH sensors takes place BEFORE autoclaving (see typical workflow Fig. 5-7).
• The calibration of DO sensors only takes place AFTER autoclaving (see typical workflow Fig. 5-7).
Add a few drops of water into the bioreactor for autoclaving as the sensors should ideally be autoclaved
in a steam atmosphere.
57
58
Hardware and operation
DASbox® Mini Bioreactor System
English (EN)
Seal the connectors of the sensors with the corresponding cap in order to prevent the ingress of
moisture.
CAUTION! Risk of damage to sensors.
Do not autoclave the pH sensors in deionized water under any circumstances.
The electrode gel will otherwise bleed out.
Information on the use of single-use bioreactors
• Autoclavable sensors which are operated in single-use bioreactors can be sterilized in advance and then
fitted into the single-use reactor under sterile conditions.
For more information, also refer to the BioBLU® 0.3c/f Single-Use Vessel Instructions for Use.
5.4.2
Calibrating sensors
The DASGIP Control software contains procedures for carrying out parallel one or two-point calibrations of
pH and DO sensors:
In the navigation tree on the left side, right-click on the
desired calibration entry to open the context menu.
Click on Run to start the calibration procedure.
Refer to the User Manual DASGIP Control. This manual contains detailed descriptions how to carry out
sen‐sor calibrations using the control software.
Observe the following information on calibrating sensors:
pH sensors - information on calibrating
We recommend carrying out a two-point calibration of the pH sensors before autoclaving (see workflow,
Fig. 5-7).
When carrying out calibration, take into account the desired working pH-range for the intended use.
Typically, the buffers pH 4 and pH 7 can be used for calibration.
Note: Do not mix up sensor channels.
During the cultivation process, the sensors must be used for the MP8-pHpO module channels
for which they were previously calibrated. Subsequently mixing up the sensor channels will
make it necessary for the calibration to be repeated.
After disconnecting the sensors from the sensor module (e.g., for autoclaving purposes),
make sure they are reconnected with the correct assignment.
Hardware and operation
DASbox® Mini Bioreactor System
English (EN)
DO sensors - information on calibrating
The following information also applies to DO sensors for use in single-use bioreactors.
• In contrast to the pH sensors, the DO sensors are only calibrated AFTER autoclaving.
The slope of the sensor can be influenced by the autoclaving process.
• We generally recommend a one-point calibration (at 100 % saturation) immediately before the start of
the main procedure (see workflow, Fig. 5-7).
• A two-point calibration is only necessary for processes in very low DO ranges or which require a very
high level of accuracy.
• Calibration must always be carried out BEFORE the culture is inoculated.
• Calibration can be carried out in the culture medium. The medium must be in a state of equilibrium with
the ambient air, i.e., saturated at 100% with the oxygen of the ambient air.
• To achieve the saturation state, set a medium gassing rate, start a light agitation and control the temperature of the medium to the desired operating temperature.
• Ensure that operating conditions are constant.
• As soon as a constant DO value has been reached, the calibration procedure can be started in the
DASGIP Control software.
For more information, refer to the User Manual DASGIP Control.
Redox sensors - verification of the correct functioning
Their correct functioning can be verified with the aid of buffers with defined redox potentials or a Chinon /
Hydrochinon redox test.
Please follow the instructions in the documentation provided by the sensor manufacturer.
The DASGIP Control software features a check procedure which supports such a function test.
If you have any questions, contact a technician at the Eppendorf Bioprocess Center.
Level Sensors
Level sensors do not need to be calibrated.

pH sensors - handling instructions
Please observe the following instructions for the correct handling of pH sensors to ensure the proper
function of the sensors.
In addition, always also observe the instructions of the respective sensor manufacturer.
General
• pH sensors generally have a limited service life.
Their aging is essentially accelerated by the number of autoclaving cycles.
• The thickness of the source layer of the sensitive glass increases over the course of time, contributing to
the inertia of the sensor. The sensor becomes slower.
• After several autoclaving cycles, the electrolyte can take on a brown discoloration. This has no effect on
the functioning of the sensor.
• Signs of contamination of the diaphragm include:
•
•
•
•
Long response times
Unstable measurement signals
Strong offset shifts
Low sensor slope
You can find information on the regeneration of pH sensors in chapter 7.3.2.
Correct storage
Store the pH sensors upright in KCl solution
(Mettler Toledo 3.0 mol/l, Broadley James 3.8 mol/l).
You can store the pH sensor in buffer pH 4 for a short period if no KCl solution is available.
Rinse the sensor with tap water and pat it gently dry when you remove it from the KCl solution before
use.
CAUTION! Risk of sensor damage.
Do not leave the sensor in the open air for a long period of time.
Do not store the sensors in deionized water.
The electrode gel will otherwise bleed out.
Visual sensor check
Before each use of the pH sensors, inspect the sensors for the following:
• The plug connector must be dry and free from signs of corrosion and contamination.
Otherwise, the transmission of measured values may be interrupted.
Hardware and operation
DASbox® Mini Bioreactor System
English (EN)
• The sensor cables must not have any sharp bends or be brittle.
• The sensor tip must be completely filled with electrolyte solution.
If necessary, shake the sensor gently like a clinical thermometer, so that it fills up.
• The pH-sensitive glass of the sensor tip must be free of cracks, scratches or deposits.
• Usually, the diaphragm of the pH sensor is white.
Gray-black discoloration indicates contamination with sulfide.
Refer to the chapter 7.3.2 for information on cleaning and regeneration of pH sensors.
Checking the raw signal of the pH Sensors
During the calibration process of the pH sensors, pay attention to the raw signal of the sensor as an
important indicator of its proper functioning.
• Limit values:
pH 7 buffer raw 0 mV ± 5 mV
pH 4 buffer raw 180 mV ± 10 mV
• Regenerate the sensor or replace it if the sensor slope is below 90% after a two-point calibration.
Note:
The raw value (raw) in mV can be displayed during the calibration procedure by clicking on
the pH sensor symbol.
For information on carrying out calibration, refer to the User Manual DASGIP Control.
5.4.4
DO sensors (Clark type) - handling instructions
Please observe the following instructions for the correct handling of DO sensors to ensure the proper
functioning of the sensors.
In addition, always also observe the instructions of the respective sensor manufacturer.
Visual sensor check
Before each calibration and each time the DO sensors are used, check the following points:
• The plug connectors must be dry and free from signs of corrosion and contamination. Otherwise, the
transmission of measured values may be interrupted.
• The sensor cables must not have any sharp bends or be brittle.
• Inspect the sensor membrane for visual signs of damage or contamination.
• Clean contaminated membranes by wiping with a soft, damp cloth.
61

DASbox® Mini Bioreactor System
English (EN)
• Replace membranes with strong signs of wear or scratches.
• Replacing the membrane body can also be useful in the case of non-calibrated sensors, long response
times, unstable measured values or significant drift of measured values.
• Replace the electrolyte solution at regular intervals (see chapter 7.3.1).
Note:
A baggy membrane has no effect on the functioning of the sensor, as long as the membrane is
intact.
Checking the raw signal of the DO Sensors
During the calibration process of the DO sensors, pay attention to the raw signal of the sensor as an
important indicator of its proper functioning.
• Limit values:
100% DO raw between 50 nA and 100 nA (slope)
0% DO raw 0 up to 3 nA (offset)
Polarize
The sensors must be allowed to polarize for approximately 10 h before use.
For this, connect the sensors to the corresponding connectors on the pHpO sensor module and switch
on the device.
Note:
Polarized sensors may be temporarily disconnected from the sensor module. However, an
equally long subsequent polarization time should always be observed afterwards.

Functions
6.2.1
Gassing
When configuring cultivation processes, any profiles for gassing rates and gas compositions can be defined
in advance.
For the duration of the process, several options are available to intervene in the control and to change current process values:
In the DASGIP Control software process view, click on the
Gassing symbol to display the gassing control parameters.
Change current set-points by clicking on the desired fields
and overwriting the respective values contained there.
Gassing as part of DO cascade control
The cascade control for the oxygen concentration which is implemented in the software ensures that the
parameters listed below are successively increased in order to maintain the predefined set-point for the O2
content of the culture:
• Oxygen content in the inlet gas (XO2)
• Gas flow (F)
• Stirrer speed (N)
The order of the parameters changed depends on the field of application.
• With cascade control in microbiology applications, the gassing rate is increased as the last
step as the possible formation of foam is a critical factor here.
• In contrast, high shear forces are not desired in cell culture applications. Consequently, the
stirrer speed is not considered, or optionally only increased as the last parameter, in the
cascade for cell culture applications.
Please refer to the User Manual DASGIP Control for detailed information on configuring gassing profiles, setting specific parameters, special gassing strategies and options for intervention during the process run.

Only devices which meet the requirements of IEC 950/EN 60950-1 (UL 1950) standards may be connected
to the interfaces.
CAUTION!
The maximum load capacity of the relay contacts is 30 VDC / 1 A.
9.4.2
RS485 (optional)
The RS485 communication ports are galvanically insulated from the rest of the device electronics.
The pin assignment complies with the specification "Modbus Over Serial Line Specification and Implementation Guide Version 1.0". The B/D1, A/DO and Common supply lines of the two RJ45 connectors are
directly connected to one another.
