3.4
Features
The Galaxy 48 R CO2 incubator is microprocessor-controlled and designed to ensure accurate and reliable
operation.
3.4.1
Operating controls
The incubator incorporates a sophisticated control system that allows for easy programming, control and
monitoring of the chamber conditions.
3.4.2
Direct heating system
The direct heating system, utilizing a thermal heating element, completely surrounds the incubator,
providing an even temperature within the chamber. The independently and directly heated outer door is
designed to ensure an even distribution of heat. This system ensures a rapid, controlled return to optimum
chamber conditions after an outer door opening while also preventing any overshoot. The incubator’s
direct heat system provides for optimal use of laboratory space by allowing the most efficient internal
volume for the footprint of the instrument.
3.4.3
Infrared sensor
A solid-state infrared sensor controls the level of CO2. It provides excellent reliability while remaining
unaffected by humidity. The CO2 system has a semi automatic zero system (Auto-zero) to re-reference the
sensor baseline to atmospheric CO2 levels at regular intervals. This provides accurate CO2 control.
3.4.4
Water tray
A water tray at the bottom of the incubator creates a high, uniform relative humidity (RH) while preventing
condensation in other parts of the chamber. Perforated shelves are provided as standard to facilitate
recovery of RH conditions in the chamber.
3.4.5
Seamless chamber
The 48 Liter chamber is seamless, and provides a sanitary and easy-to-clean environment. All internal
components are manufactured from polished stainless steel. The non-tip shelves, shelf racks and water tray
are easily removeable without tools for thorough cleaning and are able to be sterilized. Air circulation is
achieved without the use of a fan, which eliminates ductwork (a potential source of contamination),
simplifies cleaning, eliminates vibration, and facilitates use of microplates and low-volume culture.
3.4.6
Standard features
The Galaxy 48 R contains many standard features usually seen as options. It has a sealed glass door with a
covert window to allow viewing of the cultures without compromising the internal atmosphere. Also
available is a 2-split-door option (to coordinate with shelves), which is ideal for critical hypoxic studies. In
addition, there is a 25 mm (1 in) access port to allow for seamless integration of independent probes or
other equipment through the chamber. A building management system (BMS) relay is standard on every
incubator and allows alarms to be transmitted to a central monitoring system. All units are also equipped
with an RS-232 port that allows the incubator to be connected to a PC for the recording of operating
parameters.

Product description
New Brunswick™ Galaxy® 48 R
English (EN)
3.4.7
Multiple options
The incubator features multiple options that can be installed to simplify maintenance and provide superior
control over experimental conditions.
For example, high-temperature disinfection quickly and conveniently disinfects the incubator’s chamber at
120 °C, without the need to remove interior components or the CO2 sensor (except the optional O2-sensor).
A warning system warns the user before the water tray runs out of water, preventing dehydration of
samples. The water tray must be emptied and the device must be clean and dry prior to running
high-temperature disinfection.
Oxygen control provides for conditions that require below-ambient oxygen levels. For a complete list of the
available options, (see Available options for device on p. 73).
3.4.8
Two-level alarm system
The incubator incorporates a two-level alarm system. The system alarms occur only, if a problem develops
with system components that require user intervention to rectify. The incubator also incorporates an
over-temperature safety system that operates independently from the main control system.
3.5
Stacking devices
The incubator is not designed to be directly stackable. A second incubator may be safely stacked on top of
another identical incubator by using the custom-designed stacking stand available as an accessory. It is not
possible to put any other type of incubator or heavy apparatus on top, as the top cover and stacking stand
were not designed to support any other device.

Preparing for operation
WARNING! Risk of personal injury
 Do not forget to remove the sensor protective covers when putting the device into routine
work. If the covers remain on the sensors, e.g. CO2 will continuously flow into the
incubator and possibly leak out of the device.
1. Remove the black protective cover from the CO2 sensor, taking care not to remove the white porous
cover.
Save the black cover for reuse when the incubator is to be cleaned.
2. Connect the incubator to a earthed/grounded power supply.
3. Switch the incubator on.
The display will illuminate immediately.
4. Turn on the CO2 gas supply. The pressure regulator of the gas supply is to be set to 0.05 MPa (0.5 bar/
7.2 psi) unless operating with N2 or O2.
5. The chamber setpoints are pre-programmed at 37 °C and 5 % CO2. Leave the incubator on until the
programmed chamber temperature and CO2 concentration have been reached.
• The CO2 valve is disabled until the incubator reaches the temperature setpoint. After the
temperature setpoint is reached, the CO2 valve is activated.
• If power is interrupted to the incubator long enough for the temperature to drop below
setpoint, the CO2 valve will be deactivated until temperature setpoint is achieved again.
This procedure serves to avoid spurious CO2 readings.
6. Leave the incubator running for at least two hours (preferably overnight) to allow conditions to stabilize.
CO2 sensors are calibrated at the factory to control accurately at 5 % CO2 and 37 °C. Changing the
temperature or the CO2 value setpoints leads to deviations in accuracy.
 Close the outer door properly to avoid condensation or contamination.

Using the water tray
NOTICE! Risk of material damage
 To avoid possible damage to the CO2 sensor, never leave water in the water tray while the
incubator is switched off, or when a high temperature disinfection cycle is initiated
(optional feature).
 Allow a clearance of 15–20 cm (6–8 in) to allow access for oxygen sensor removal.
• The water tray has to be left in place at all times.
• Use distilled water only in the water tray. The usage of any other types of water including
deionized water and chlorinated additives will cause corrosion inside the incubator.
• Do not move the incubator, when the water tray is filled. Spilled water could cause
corrosion in the chamber.
If humidification is required:
1. Fill the water tray with 0.5 L of warm distilled water (around 37 °C).
2. To reduce the risk of contamination, clean the tray every 10–14 days with a solution of 70 % isopropyl
alcohol and 30 % distilled water.
Refill the tray with 0.5 L of warm distilled water when clean.
The humidity level within the chamber is not adjustable. The chamber will reach between 85
and 95 % relative humidity at 37 °C (depending on ambient humidity) using the water tray.
5.3
Programming
5.3.1
Programming CO2, O2 and temperature
Perform the following steps to set the desired operating temperature, O2 and CO2 level.
1. Press the PROG function key.
2. In the PROG screen that appears, press the desired function key, TEMP, O2 or CO2, then use the
and
direction keys to adjust the value.
If the incubator is supplied with the option of oxygen control, the setpoint for the oxygen level
can be selected and changed like the temperature and CO2 setpoints.
3. When the desired setpoint is displayed, press the ENTER function key.
4. After making adjustments (if any were made), allow the incubator to stabilize at the setpoints before
continuing.
If the chamber temperature goes above the temperature setpoint by 1 °C, the
over-temperature system will activate.
Operation
New Brunswick™ Galaxy® 48 R
English (EN)
Program the required oxygen level in the PROG screen, following the onscreen instructions.
If you are running an O2 level programmed between 0.1 - 0.9 %, you should know that the
control system is set to operate in the following way to minimize N2 consumption after the
outer door has been opened:
• The N2 valve is switched on continuously until the O2 level is within 0.1 % of setpoint.
• The CO2 valve is then switched on to allow the CO2 level to reach setpoint. If the O2 level is
above setpoint 15 minutes after the N2 valve has been switched off, it is switched back on
for 40 seconds and the CO2 valve is switched on for 20 seconds. The CO2 valve will then
pulse until setpoint is reached.
• The process described above will repeat itself until the O2 setpoint is reached.
• The same process will also repeat if the O2 level rises above setpoint, and if the O2 level
should rise toward 0.2 % above setpoint, the N2 valve will open again continuously until
the O2 level returns to setpoint.
• The CO2 autozero, which would normally take place after a CO2 alarm, will be cancelled to
avoid the introduction of additional O2 into the chamber. For the same reason, we
recommend canceling the programmed CO2 autozero.
5.3.2
User access code
Programmable user access code allows you to restrict access to the PROG, USER, and ALARM screens
(where settings can be changed) to authorized persons only.

1. Press the PROG function key to enter the PROG screen.
The user access code will be displayed as a series of 4 asterisks.
2. Use the left and right direction keys to move to each code position, and the up and down direction keys
to select a number from 0 – 9.
3. Once the number is selected, press the ENTER function key to save the code.
4. After returning to the main screen, programming access will require the code to make any further
programming changes.
Take care to note your password somewhere. If a password is forgotten, you must contact a
customer service representative to recover or delete the forgotten password.
5.3.3
Removing user access code
1. In the PROG screen, enter the current access code.
2. Now program 0000 as the new access code.

PROGRAMMABLE CO2 AUTOZERO
When you select this feature, the PROGRAM CO2 AUTOZERO screen (see Fig. 5-2 on p. 33) allows you to
program the autozero frequency and time, or to run the autozero function manually.
We recommend that you autozero the CO2 system:
• Prior to using the incubator for the first time.
• Once a month when your incubator is operating, to ensure that the CO2 level is as accurate as possible.
• After the incubator has been in storage (or transit) for a while.
The autozero system automatically re-references the CO2 Sensor to atmospheric CO2 in the following way:
1. A pump activates for two minutes, pumping atmosphere at 0.3 liters/minute into the sensor’s measuring
chamber. This displaces the chamber atmosphere completely from the sensor.
Abb. 5-2: PROGRAM CO 2 AUTOZERO screen
Fig. 5-2:
PROGRAM CO2 AUTOZERO screen
This procedure does not affect the internal chamber environment and will not affect your cell
culture as it is being performed.
2. After the pump shuts off, the control system adjusts the autozero Factor to reference the sensor to 0.05
% CO2, which is the approximate atmospheric level.
3. The pump switches off and the chamber atmosphere diffuses back into the sensor’s measuring
chamber. This takes three minutes, after which the normal CO2 control system takes over.
4. The result of the autozero (listed as A/Z on some screens) is sent to the DATALOGGER ALARM EVENTS
screen so that a record of the results will be kept.
The frequency of autozeroing can be set in steps between once a day and once every 28 days. The default
setting is once every 28 days. If not required, it can be disabled (see DISABLE on p. 34).
33
34
Operation
New Brunswick™ Galaxy® 48 R
English (EN)
The default time setting is 7:00 am. This can be altered to suit your requirements. We recommend that you
only change the time setting shortly before you start to use the incubator.
The autozero will only occur if the temperature is at setpoint. If the temperature is not at
setpoint, the system will postpone autozero until the setpoint is achieved.
If the autozero function is to be run manually, simply press the START function key, within the PROGRAM
CO2 AUTOZERO window.

TEMPERATURE GRAPH + DOOR OPEN BAR CHART
When you select this from the DATALOGGER screen, the Door Open bar chart is shown at the top of the
screen to associate it with a temperature disturbance (see Fig. 5-5 on p. 37). A temperature reading is
recorded every 18 seconds while the temperature is outside the specification of ±0.1 °C and each reading is
shown as a single pixel.
When the temperature has settled within specification, the recording is compressed to one pixel
representing (10) 18-second readings (as long as the temperature remains in specification). This allows up
to 10 hours of readings to be displayed on one screen. When the temperature moves outside specification,
for instance if the outer door is opened, the graph reverts to individual 18-second readings until
temperature is within specification again.
When the data is compressed or decompressed, a light dotted line is displayed vertically on the screen to
signify that the time axis is changing from 18-second to 10 x 18-second increments or vice versa (see
Fig. 5-6 on p. 37).
A heavy dotted line (not shown) is displayed when the incubator is switched on.

For disconnecting the tubing, press down the small ring of the tube connector and pull out the
tubing.
5.13.2
Setting up oxygen control (0.1–19 %)
Oxygen control lets O2 and CO2 levels achieve at approximately the same time, via control of the N2 valve's
duty cycle (but within the range of 0.1–19 % O2).
1. Remove the black plastic protective cover (making sure that the hydrophobic filter cap is not removed
with it) from the port inside the chamber. Retain the cover for use when you clean the chamber.
2. Open the nitrogen gas supply from the tank and set the N2 tank’s outlet pressure gauge to 1.5 bar.
3. Set the N2 inline pressure regulator to 0.1 MPa ( 1.0 bar, 14.5 psi). The gas flow rate is approximately 20
liters/minute.
Operation
New Brunswick™ Galaxy® 48 R
English (EN)
• If the programmed O2 level is close to the ambient oxygen, it may be necessary to reduce
the cylinder pressure below 1 bar to stop the oxygen level from undershooting the
programmed value.
• When working at 0.1 % O2, set the CO2 pressure to 0.1 MPa ( 1.0 bar, 14.5 psi).
Be sure to humidify the incubator and leave it overnight to stabilize before proceeding further.
To automatically calibrate the sensor to atmospheric oxygen levels, select OXYGEN SENSOR – REF TO
ATMOSPHERE in the USER menu, and then follow the onscreen instructions.
The oxygen reading is automatically adjusted to 19.7 %, which is the true reading taking into account the
relative humidity in the chamber.
Under normal humidity conditions (95 - 99 % RH), the sensor is unaffected. If for any reason
(such as a large spill inside the chamber or the incubator being switched off while fully
humidified) liquid condenses around the sensor, the result may be restriction of gas flow and a
low sensor signal. Should such condensation appear on the chamber walls, normal operation
can be easily restored by removing the humidity tray, drying the chamber completely, and
then running the incubator at 37 °C for one hour. This will dry out the sensor. After the hour
has elapsed, the humidity tray can be reinstalled and the incubator humidified again.
5.13.3
Setting up oxygen control (1–19 %)
This oxygen control option is designed to cover the 1 – 19 % range by adding nitrogen to bring the level
below ambient.
1. Remove the black plastic protective cover from the hydrophobic filter cap (making sure that the
hydrophobic filter cap is not removed with it), located in the rear wall of the incubator chamber. Retain
the cover for use when you clean the chamber.
2. Open the nitrogen gas supply from the tank. Set the N2 tank’s outlet pressure gauge to 1.5 bar
3. Set the N2 inline pressure regulator to 0.1 MPa ( 1.0 bar, 14.5 psi). The gas flow rate is approximately 20
liters/minute.
If the programmed O2 level is close to the ambient oxygen, it may be necessary to reduce the
cylinder pressure below 1 bar to stop the oxygen level from undershooting the programmed
value.
4. After the incubator has been humidified and left overnight to stabilize, select the USER menu; then,
using the
or
direction key, select OXYGEN SENSOR-REF TO ATMOSPHERE and follow the
onscreen instructions to automatically calibrate the oxygen sensor to atmospheric oxygen levels. The
oxygen reading is automatically adjusted to 19.7 %, which is the true reading taking into account the

Operation
New Brunswick™ Galaxy® 48 R
English (EN)
We recommend that you repeat the OXYGEN SENSOR-REF TO ATMOSPHERE procedure in step 4 (see
Referencing to atmosphere on p. 49), and further details once a month to ensure that any long-term drift in
sensor output will be corrected. Be sure to do it at the chamber operating temperature.
When you are cleaning the chamber, be very careful not to wet the oxygen sensor or CO2 sensor. Never use
solvents on the sensor membrane; rather, be sure to cap the hydrophobic filter before you clean. It is good
practice to replace the filter each time you clean the incubator chamber, to avoid the possibility of filter
contamination.
Under normal relative humidity conditions (95 – 99 %), the oxygen sensor’s performance should not be
affected. If, however, liquid condenses around the sensor, gas flow may become restricted, giving the
sensor a low signal. This may occur if there is a large liquid spill inside the chamber or if the incubator is
turned off while it is fully humidified. Should such condensation appear, normal operation can be restored
by:
1. Removing the humidity tray,
2. Drying the chamber completely,
3. Running the incubator at 37 °C for one hour.
This will dry out the sensor(s). The humidity tray can then be reinstalled and the incubator can be safely
re-humidified.
5.14
Referencing to atmosphere
The oxygen sensor is a self-powered electrochemical cell with a finite life that is dependent on the ambient
oxygen level. A typical lifespan is 1 – 2 years at atmospheric levels. During the sensor's lifespan, the signal
produced will slowly degrade until it is ultimately unuseable. For this reason, we recommend that you
reference the sensor to atmospheric oxygen levels on a monthly basis.
To reference the sensor to atmosphere, enter the USER menu and select OXYGEN SENSOR-REF TO
ATMOSPHERE.
This procedure has 3 possible outcomes:
1. The test was completely successful, and no further action is needed until the next month's test.
2. The sensor needs to be replaced soon (see Replace sensor soon on p. 50).
3. The sensor needs to be replaced immediately (see Replace sensor now on p. 50).

Humidity alert and monitoring package
The humidity alert package includes a humidity tray warning system and humidity display and alarm
function, both providing optimal feedback on relative humidity inside the incubator chamber.
5.17.1
Humidity tray warning system
The humidity tray warning system is designed to prevent the water level in the humidity reservoir from
becoming too low. The water level is continuously measured by an optical water level sensor. If the water
level in the humidity tray become too low a HUMIDITY WATER LOW ALARM is displayed. This alarm can be
cancelled by pressing any key, but it will re-activate when the door is opened and closed.
The humidity alarm system can be deactivated as follows:
Humidity tray warning system with high temperature decontamination option.
NOTICE! Risk of damage to equipment
The humidity warning sensor can not be dismantled.
 Never bend the metal tube which came from the back side of the chamber. Just flip the
downward part (with the sensor) with the rubber tube to take out the water tray.
1. Press USER.
2. Select DISABLE and toggle HUMIDITY WARNING from ON to OFF using the
keys.
3. Press ENTER.
4. Refill the humidity tray with 0.5 liters of warm (~37.0 °C) distilled water.
When the water level has been replenished and the door is closed the system will re-arm.
5.17.2
Humidity display and alarm system
The humidity display and alarm system is designed to measure the relative humidity level (rH) in the
chamber and to display the chamber rH on the display screen. Under normal operating conditions and
using the supplied humidity tray, the rH level will reach a maximum of 95 - 96 % after being left overnight.
The humidity sensor will activate an alarm if relative humidity falls below the preset limit of 88 %. The
sensor is located on the rear wall of the chamber, below the CO2 Sensor. The humidity display is always
active, but the alarm system can be deactivated as follows:
1. Press USER.
2. Select DISABLE, and toggle RELATIVE HUMIDITY from ON to OFF using the
keys.
3. Press ENTER.
The alarm system is disarmed for 1 hour or when it achieves 88% R/H, when the incubator is switched on,
or if the door is opened and closed.
Operation
New Brunswick™ Galaxy® 48 R
English (EN)
An alarm is signaled by a flashing RH LOW ALARM message. If the humidity level rises above 88 % during
the 1 hour time out period, the humidity alarm system will be armed. The alarm will then be triggered when
the R/H level falls below 88 % and will be recorded by the alarm log. The alarm can be acknowledged by
pressing any key. No further alarms will occur unless the door is opened and closed, or power to the
incubator is removed then restored.
The humidity sensor is protected by a white porous plastic cover, care must be taken not to
spill any liquid into the sensor. The white porous cover should be protected with the black
plastic sleeve provided when cleaning the incubator. The white porous cover can be removed
and autoclaved but care should be taken not to touch or wet the sensor when the cover is
removed.

RS-232 interface
An external computer can be connected to the serial interface for data logging using optional BioCommand
SFI software, or by remote control with a communication program. Data from the incubator can be
downloaded for record keeping or validation documentation. The device can be controlled remotely and
operating parameters can be transmitted and recorded using third party software. Information on installing
and operating the communication program can be found in the corresponding software documentation.
The RS-232 interface port provides a connection for the incubator to a personal computer or terminal. This
allows the incubator’s operating status to be viewed on the screen.
The computer should be connected to a mains/power supply outlet as close as possible to the
incubator.
Prerequisites
• A PC or terminal, capable of RS-232 communication, with one serial com port free for this connection or
a serial interface box.
• A null-modem screened cable of suitable length. To ensure reliable communication, the cable should
not exceed 15 m (49 ft) in length. One end must have a 9-pin female D connector, to connect to the
incubator’s RS-232 port, and the other end must have either a 9-pin or 25-pin female D connector,
whichever mates to your PC or terminal.

6.1
O2 sensor
If the oxygen sensor fails suddenly, it is very likely that the sensor inlet membrane has become blocked by
condensation. This can be seen on the DATALOGGER screen as a sudden drop from the programmed value
to nearly zero.
To dry the membrane:
1. Remove the humidity tray.
2. Remove the hydrophobic filter holder assembly (see Replacing the filter disc on p. 53) by unscrewing it
(counter-clockwise).
3. Program the incubator for a temperature of at least 37 °C (or higher if you normally operate the
incubator at a higher temperature).
4. Close the door and allow the temperature to recover.
5. Reopen the door for 15 seconds to release any build-up of humidity.
6. Repeat steps 3 and 4 every 30 minutes while monitoring the DATALOGGER O2 Graph. The oxygen level
should recover after a few hours.
7. Leave the incubator for a few more hours to be ensure that the sensor membrane has thoroughly dried
out.
8. Replace the hydrophobic filter disc (see Replacing the filter disc on p. 53).
9. Re-humidify the incubator.
10. After 2 to 3 hours, carry out an OXYGEN SENSOR-REF TO ATMOSPHERE (see Referencing to atmosphere
on p. 49). When the referencing has been successfully completed, the incubator is ready for use.

7.1.1
General
WARNING! Risk of injury to personnel or damage to equipment!
 2 stacked incubators should not be moved for maintenance or cleaning.
To ensure that chamber conditions remain stable, minimize the length of time that the door is open. The
magnetic door catches are specifically designed to make door opening and closing as easy as possible.
When you open the door, wipe off any small drops of condensate that may have formed on the inner seal.
This will avoid a build-up of condensation.
If you are using the humidity tray for humidification, (see Using the water tray on p. 30).
7.1.2
Daily checks
1. Check that the temperature and CO2 levels are reading within specification.
2. Check the reserve pressure in the CO2 cylinder (normally 725 PSI (50 bar) when full). The design of the
incubator ensures very low consumption of CO2. During normal working conditions, a typical large
cylinder should last approximately 12 months (frequent door openings will deplete the supply more
rapidly). If there is a significant drop at the cylinder pressure of 725 PSI (50 bar), it means that the
cylinder is almost empty and should be replaced. Ensuring that there are no leaks at any of the
connections will ensure a greater lifetime to the CO2 supply and will help avoid accidentally running out
of CO2.
3. Any spills in the chamber should be cleaned immediately.
4. Check the DATALOGGER screen for any alarms or events that may have occurred overnight.
7.1.3
Weekly checks
Use distilled water only in the humidity tray. Use of any other types of water including
deionized water and chlorinated additives will cause corrosion inside the incubator.
Refill the humidity tray with 0.5 liters of distilled water. The use of warm water will ensure a rapid return to
optimum chamber conditions.
7.1.4
Monthly checks
We recommend routine replacement of the water in the humidity tray, and that you clean the tray at the
same time.
If required, you can take a sample of the gas inside the chamber using the CO2 sample port, and check it
using a CO2 gas analyzer (see Accessories on p. 73).
Displayed chamber CO2 level will drop during sampling, but it will recover once the sampling
is complete. This is merely a sensor characteristic; the CO2 level in the chamber is actually not
affected.
We recommend that you perform a CO2 autozero prior to sampling. We also recommend that
you autozero the CO2 system at least once every 28 days to ensure that CO2 level is correct.

CO2 Sampling with analyzer
The CO2 sample port is located on the rear of the incubator, near the top (see Fig. 3-1 on p. 15).
If you conduct a sampling, please ensure the following:
• Turn off the CO2 gas by re-programming the setpoint for CO2 to 0.0 % to prevent CO2 from being
injected into the chamber and giving a false reading.
• A flow rate ≤ 0.5 liters/minute is used to take a sample.
• The door is kept closed.
• Reset the CO2 setpoint to the desired level after sampling.
We recommend that you perform a CO2 autozero prior to sampling. We also recommend that
you autozero the CO2 system at least once every 28 days to ensure that CO2 level is correct.

7. Wipe the internal components of the chamber twice with the alcohol/water solution. Wipe off excess
liquid and leave it to dry completely.
8. Reassemble the shelf racks, shelves, and water tray before switching the incubator on. Wipe the inner
door seal with the alcohol solution, rinse and leave it to dry.
9. Ensure the protective covers are removed from all sensors. Keep them aside. Be very careful, as you
remove the black CO2 sensor cover, not to accidentally remove the white porous sensor cover. The white
cover must remain in place.
10. O2 option: Check if the hydrophobic filter disc and the hydrophobic filter cap of the O2 sensor are at
their place.
11. Refill the water tray (see Using the water tray on p. 30). When reinstalling, ensure that the water tray is
pushed fully back.
12. Leave the incubator on for at least two hours (preferably overnight) to allow conditions to stabilize.
13. When the incubator has stabilized, carry out an Auto-zero and reprogram the desired CO2 level. It may
be necessary to open the inner door briefly if the CO2 level is too high after performing an Auto-zero.
