The Innova 44/44R stackable incubator and incubator refrigerated shakers are large-capacity
Product description
orbital shakers that utilize a triple eccentric counter-balanced drive mechanism. They provide
horizontal plane rotary motion in either a 2.54 cm (1 in) or a 5 cm (2 in) diameter circular orbit,
depending on the model. A Proportional/Integral (PI) microprocessor controller with
instantaneous digital feedback controls the speed over the entire speed range.
The Innova 44R provides temperature control from 20 °C below ambient (as low as 4 °C) to 80
°C, and the Innova 44 from 5 °C above ambient to 80 °C. Naturally, both these ranges depend
on relative humidity and other ambient factors, as well as the options installed in the unit.
Ambient temperature is measured at one meter from the exterior of the unit.
Erlenmeyer flasks (up to 5 liters in size) as well as a wide variety of tubes and plates can be
accommodated using the New Brunswick shaker accessories described in a later section
(see Accessories on p. 58). These are easily accessed on slide-out platforms.
The Innova 44/44R may be operated in the following ways:
• Continuously: at a set speed and temperature, until user intervention.
• In a timed mode: run at a set speed, time and temperature for a period of up to 99.9 hours,
after which the shaker automatically shuts off.
• Via the shaker’s programmable controller: run through multiple temperature and speed
changes for an extended period of time.
For more details on these various modes of operation, (see Operation on p. 37).
For safe operation, the Innova 44/44R shakers are designed with a safety switch that
automatically stops the shaker mechanism when the door is opened.

6.9Stack a third shaker
Equipment damage
When stacking three shakers, do not use a base taller than 10.5 cm (4 in).
CAUTION!
When stacking three shakers, all shaker loads must be balanced. These shakers operate
best at maximum speed with a load of 15.5 ( ± 1.4) kg or 34 (± 3) lb, which includes all
platforms, clamps, and filled glassware.
For three stacked 2 in stroke shakers, maximum operating speed must be limited to 250 rpm.
To stack a third shaker, repeat the appropriate procedures provided above to install the stacking
kit, to stack the shaker, and to level the entire assembly.
• START/STOP SWITCH: This switch is used to start or stop the shaker. It will also activate the
timer when a timed run is desired. If the unit is stopped and restarted, the timer automatically
returns to the beginning of a run.
• CONTROL KNOB: This knob is multifunctional. It is used to change screens and to select
and change operating conditions.
• RS-232 PORT: For details (see Software interfaces on p. 31).
• POWER SWITCH: This rocker switch is a circuit breaker that turns power on and off to the

The Innova 44/44R can be equipped with a factory-installed remote alarm component (part
number M1320-8029). When it is hooked up to your relay and receiving equipment, this device
will send notification of an alarm condition to the remote location you choose.
The Innova 44/44R is equipped with a space-saving glide-up door.
When the door opens, the following will happen:
• Heater turns off
• Shaker stops
• Interior light goes on and, when it is in AUTO mode, will remain on for 15 seconds after the
door is closed
• UV germicidal lamp (if so equipped) turns off
• Photosynthetic lights (if so equipped) turn off.
7.7Spill pan/water reservoir
The Innova 44/44R is equipped with a spill pan to protect the drive mechanism in the case of
accidental spills and/or broken glassware. This pan can also be used as a water reservoir to
humidify the chamber and to reduce evaporation. An optional factory-installed humidity monitor is
also available.
7.8Software interfaces
The RS-232 port is located below the Power Switch on the right side of the control panel
(see Fig. 12 on p. 26). It can be used to interface a PC to the shaker for control of operating
conditions or data logging applications (see Appendix A: Remote programming on p. 64).
The customer is responsible for securing the proper driver to interface with the RS-232.

Features
7.9Interior light(s)
When the LAMP screen is in its default AUTO mode, the interior (“chamber”) light is activated for
15 seconds whenever you turn the Control Knob. It will automatically shut off after 15 seconds of
Control Knob inactivity.
The chamber light will also go on when the door is open.
In addition, you can set the chamber light to be continuously ON or OFF by selecting either mode
in the LAMP screen.
There are two additional light options for refrigerated units only: interior photosynthetic growth
lamps (see Optional photosynthetic lamps on p. 35) and a UV germicidal lamp located outside
the chamber but in the airflow path (see Optional UV germicidal lamp on p. 35).
7.10Heater
The chamber temperature is sensed by a 1000 ohm platinum RTD. The heater is controlled using
pulse width modulation on a 2.5 s duty cycle. This cycle time is fast enough to prevent noticeable
changes in air temperature due to the cycling.
Whenever the heater is on, the Heater On icon will appear in the display. The heater
automatically stops running when the door is opened.
7.11Refrigeration (44R only)
The refrigeration system in the Innova 44R is a fixed-capacity system carefully designed to
maintain the setpoint, to balance pressure within the system, and to prevent freezing on the
evaporator surface.
When the shaker is powered up, there is a four-minute time delay prior to compressor start-up.
7.12Service accessibility
In the unlikely event that your Innova 44/44R should need service, all electronic boards,
refrigeration and heating components are mounted on a pull-out drawer mechanism which is
easily accessed, by an authorized service technician, from the front of the shaker.
The Innova 44/44R can be used with a variety of Eppendorf platforms that will accept a wide
range of clamps for flasks, test tubes, etc. A platform, which is required for operation, is a
separate item, not included with the shaker assembly. For details on available platforms and
platform accessories, (see Accessories on p. 58).
8.2Installation of platform
In transit, there are two small plastic straps on the side of the bearing housing to secure the

8.3Install flask clamps
Flask clamps purchased for use with universal platforms (see Flask clamps for universal
platforms on p. 61) require installation. Clamps are installed by securing the base of the clamp to
the platform with the correct type and number of screws. All clamps are shipped complete with
hardware.
Clamps for 2, 2.8 and 4 liter flasks are shipped with an additional girdle to keep the flasks in
place. The girdle is an assembly of springs and sections of rubber tubing. One girdle is already in
place on the clamp, the other is packed separately. To install these double girdle clamps:
1. Place the clamp on the platform, aligning its mounting holes with holes on the platform.
Secure the clamp in place using the flat Phillips head screws provided (# S2116-3051, 10 –
24 x 5/16 in). Use figure below (see Fig. 17 on p. 34) to help you identify the proper screws,
as three different types of screws are shipped with the clamps.
2. With the first girdle in place, as delivered, on the upper part of the clamp body (see Fig. 16 on
p. 34), insert an empty flask into the clamp.
3. After making sure the sections of tubing are located between the clamp legs, roll the first
girdle down the legs of the clamp as far as it can go. The tubing sections will rest against the
platform, and the springs will be under the clamp base.
4. Place the second girdle around the upper portion of clamp body (just as the first girdle was
initially). Make sure that its spring sections rest against the clamp legs, while its rubber tubing

The three-step program we have illustrated is designed to start incubating cultures at 37 °C and
hold that temperature for eight hours, shaking at 150 RPM. After eight hours, Step 2 engages,
increasing the temperature setpoint to 40 °C for a temperature induction, holding that
temperature for three hours and increasing the shaking speed to 225 RPM. After this interval, the
temperature will be cooled to 4 °C and held at that temperature for twelve hours; no shaking will
occur during this period, as the speed is set to 0 RPM.
Please note that temperature reductions, even at temperatures above ambient (going from 40 °C
to 30 °C, for example), require refrigeration to be effective.

To reactivate the audible alarm at any time, repeat steps 1 – 3, reversing “off” and “on”.
9.7Temperature offset calibration
The temperature probe and the temperature controller are calibrated together at the factory. The
temperature probe measures the temperature of the air at the probe’s location, near the return
vent. The controller uses the probe input to adjust air temperature, up or down, to match the
temperature setpoint.
Depending on various conditions within the chamber, such as flask placement and size, the heat
produced by growing organisms, heat losses due to liquid evaporation from flasks, etc., the
display temperature may differ from temperatures within the flasks themselves. You can calculate
the correction value for this offset and program the shaker to display a corrected temperature.
9.7.1Calculate the offset value
If you wish to have the temperature display (“Indicated Temperature”) match the temperature at a
given point, or match the average of a series of points within the chamber (“Actual Temperature”),
proceed as follows:
1. Let the unit equilibrate at or near the desired temperature, then record the Indicated
Temperature.
2. Now record the Actual Temperature.
3. Calculate the temperature correction value using this formula: Actual Temperature – Indicated
Temperature = Temperature Offset Value.
4. To set the Temperature Calibration Offset, follow the procedure outlined in the next paragraph
below.
9.7.2Set the offset
To set the temperature calibration Offset:
1. Use the Control Knob to enter the CAL screen (see Fig. 34 on p. 50).
2. Turn the Control Knob to highlight the current setting (0.0 in the sample screen above), then
click the Knob in. The current setting will flash.
3. Turn the Knob (left for negative settings or right for positive settings) to display the desired
setting. As you turn the Knob, each click represents one tenth of a degree Celsius (0.1 ºC).
4. When you reach the desired setting, click the Control Knob in to save the new value.
5. When the Temperature Offset is set to any value other than 0, the asterisk icon will appear
next to ºC in the DISP and SUMM screens.

subplatform, and any flasks present are secured. Run the unit at approximately 250 RPM to
ensure stable operation prior to calibration.
When the shaker is running, the CAL screen shows the indicated RPM value. If you wish to
calibrate the speed, set the speed to a value that can be measured, a setpoint of 250 RPM works
well. The use of a strobe is recommended for accuracy. If, after measuring the actual speed, you
wish to adjust the indicated value:
1. Click the Control Knob in.
2. Set the new value.
3. Click the Knob in again to save the setting.
4. Turn the shaker OFF, wait a few seconds, then turn the shaker back ON.
In the event of a power failure, the Innova 44/44R Shakers are equipped with an automatic restart
function. The shaker’s non-volatile memory retains all stored information.
If the shaker was in operation prior to the power interruption, the shaker will begin to operate at its
last entered setpoints. The alarm/POWER display will flash, indicating that a power interruption
has occurred. Turn the Control Knob in any direction to acknowledge the visual alarm. The
flashing will stop.
The Innova 44/44R is equipped with a slide out platform mechanism as a standard feature. This
allows you to easily slide the platform out of the shaker for easy access to the platform without the
need for tools.
To operate the platform slide-out mechanism:
1. Make sure platform has stopped moving.
2. Rotate cam lever located on the subplatform (see Fig. 35 on p. 51) 180 ° clockwise. It should
be pointing to the left.

Maintenance
WARNING !
It is the responsibility of the user to carry out appropriate decontamination procedures if
hazardous material is spilled on or inside the equipment. Before using any cleaning or
decontamination method other than those suggested by the manufacturer, users should check
with Eppendorf that the proposed method would not damage the equipment.
Commercially available household bleach solutions, when diluted at a 1:10 ratio, are effective in
routine decontamination of the instrument. The method for decontaminating a spill depends upon
the nature of the spill.
Spills involving fresh cultures or samples known to have low concentrations of biomass should be
flooded with decontamination solution and soaked for 5 min before cleanup. Spills involving
samples with high concentrations of biomass, or involving organic matter, or occurring in areas
warmer than room ambient temperature, should be exposed to decontamination solution for at
least one hour before cleanup.
Personnel injury!
Personnel involved in the cleanup of any spill should wear gloves, safety glasses, and a
laboratory coat or gown during the cleanup process. Respiratory protection should be
considered for spills where aerosolization is suspected.
These specifications assume a maximum load of 15.5 kg (34 lb), including platform, clamps,
glassware and contents.

14.2Disposal
In case the product is to be disposed of, the relevant legal regulations are to be observed.
Information on the disposal of electrical and electronic devices in the European
Community:
Within the European Community, the disposal of electrical devices is regulated by national
regulations based on EU Directive 2002/96/EC pertaining to waste electrical and electronic
equipment (WEEE).
According to these regulations, any devices supplied after August 13, 2005, in the
business-to-business sphere, to which this product is assigned, may no longer be disposed of in
municipal or domestic waste. To document this, they have been marked with the following
identification:
Because disposal regulations may differ from one country to another within the EU, please
contact your supplier if necessary.
In Germany, this is mandatory from March 23, 2006. From this date, the manufacturer has to offer
a suitable method of return for all devices supplied after August 13, 2005. For all devices supplied
before August 13, 2005, the last user is responsible for the correct disposal.
HyperTerminal is only present in Microsoft® Windows XP and older.
You can use the Microsoft HyperTerminal program on your personal computer to communicate
with your shaker:
1. Before you set up HyperTerminal, be sure to check the Mode and Baud Rate parameter
settings (see RS232 Screen on p. 43).
2. While you are in the RS232 screen (see Fig. 26 on p. 43), set the Mode parameter to Slave,
and select the appropriate Baud Rate. The default setting, as you see in your screen, is
19200; your other choices are 9600 or 38400.
3. Connect the RS-232 cable between your computer and the shaker’s RS-232 port (see Fig. 12
on p. 26).
4. Start HyperTerminal, and follow the steps for Setting a New Connection. When prompted,
select the COM port you will be using, then set the COM parameters (see table below).
5. To be sure that you have established a connection with your shaker, turn the shaker OFF,
open the HyperTerminal connection, then turn the shaker back ON. Once a connection has
been made, the shaker will send an OK to HyperTerminal.
6. You may wish to send a trial command to the shaker (see Sample Test below). We suggest
that you enable Caps Lock on your computer, because all commands must be sent as capital
letters.

Flow ControlNone
Sample Test:
1. To request the current setpoint, type RS at the terminal. When you type R, you should see the
R on the computer display. This is an echo character, sent back by the Innova 44/44R. When
you type the S, you should see the echo S displayed at the computer.
2. Use the Enter key to send the carriage return control character. This will move the cursor
back over the first character.
3. RS is a Request command, so your shaker will send back the data corresponding to the
command.
15.2Overview of command sets
Using an optional RS-232 interface, the user has the capability to control various functions of the
Innova 44/44R shakers by computer. A detailed command set follows this introduction.
The serial interface uses an echo character protocol setting that is implemented to indicate that a
valid character has been received by the shaker. For every character sent by the user computer,
the Innova 44/44R will return a matching character. This echo character should be read by the
computer and compared to the character that was sent.

message to last longer than 10 seconds. If it takes any longer, the shaker’s serial port will reset
itself.
In the following example, the Master (your computer) will command (the C in CS) the shaker
(Slave) to set its speed to 150 RPM:
Master sends:Innova 44/44R responds:
In the next example, the Master (your computer) will request that the shaker (Slave) report (the R
in RV) the actual parameters:
Master sends:Innova 44/44R responds:
Then the report:
<Arg1><Tab><Arg2><Tab><Arg3>...<Arg6><CR><LF>
On power-up, even if the shaker is not set in Slave mode at the time, the shaker will always send
these four characters: OK<CR><LF>. Before starting any communications, be sure to clear the
computer’s receive buffer.
If a command has additional arguments, the ASCII space control character separates each
argument. The command is terminated using the ASCII carriage return control character; an
optional line feed control character may also be included but must follow the carriage return
character.
When a command is sent that returns data, the characters returned are in ASCII format. Each
additional argument returned will be separated by the ASCII space or tab control character; refer
to the selected command for the actual format. Data returned is terminated with a carriage return
line feed control character sequence.
The next section provides an Index to the 2 character command codes.
The next four sections provide command sets for your use for Set Commands, Profile Control
Commands, Report Request Commands and Set/Get Date & Time.
