The Innova 43/43R Incubator Shakers are large-capacity orbital shakers that utilize an eccentric
counterbalanced drive mechanism. They provide horizontal plane rotary motion in either a
1-inch (2.54 cm) or a 2-inch (5 cm) 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 43R provides temperature control from 20º below ambient (as low as 4ºC) to 80C,
and the Innova 43 from 5º above ambient to 80ºC. 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 6 liters in size) as well as a wide variety of tubes and plates can be
accommodated using the New Brunswick shaker accessories described in Section 9.11. These
are easily accessed on the platform.
To facilitate moving the unit, each shaker is equipped with casters that roll freely when the feet
are raised.
The Innova 43/43R 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.
Via computer through an RS-232 interface.
See Section 7 for more details on these various modes of operation.
For safe operation, the Innova 43/43R shakers are designed with a safety switch that
automatically stops the shaker mechanism when the lid is opened.
The Innova 43/43R is equipped with visual and/or audible alarms that alert the user to the
following conditions:
The end of a timed run
Deviations from speed setpoint
Deviations from temperature setpoint
Power failure

5.10 Heater
The chamber temperature is sensed by a 1000 ohm platinum RTD. A 650W heater is
controlled using pulse width modulation on a 2.5-second 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 lid is opened.
NOTE:
Operating the shaker for sustained periods at temperatures above 60°C may
result in a shorter fan lifespan.
5.11 Refrigeration (43R Only)
The refrigeration system in the Innova 43R is a variable-capacity system carefully
designed with self-checks 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.
5.12 Service Accessibility
In the unlikely event that your Innova 43/43R should need service, all electronic boards,
refrigeration, heating components are easily accessed, by an authorized service technician, behind the right side panel of the shaker.

6.1 Platform Assemblies
The Innova 43/43R can be used with a variety of New Brunswick 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. Refer to
Section 9.11 for details on available platforms and platform accessories.
6.2 Installation of Platform
Prior to use, a spill cover and platform must be installed on the shaker. The shaker
is shipped with four Allen head platform screws installed in the bearing housing (see Figure 5 below, which also shows the spill cover that you must install).
Flask clamps purchased for use with universal platforms (see Section 9.11.2) 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-, 4- and 6-liter flasks are shipped with an additional girdle to keep the
flasks in place (see Figure 6). To install these double girdle clamps:
1. Place clamp on platform, secure in place with correct type of screws: #S2116-3051,
10-24 x 5/16-inch flat Phillips head, provided with the clamps (see Figure 6a).
2. Place the loose girdle around the upper portion of clamp body so that it is held in
place by the legs of the clamp.
3. Insert the flask into the clamp, and push the girdle down so the rubber tubes are in
contact with the platform and the flask.

6.5 Optional Gassing Manifold Kit
This option is factory-installed. The manifold delivers gas into the chamber via as
many as 12 ports (see Figures 8 & 9 on the following page). The manifold can be
adapted to the desired tubing configuration by adding or subtracting ports or by
temporarily clamping off unused tubes. You may elect to use splitters (barbed Yconnectors) after the manifold to increase the number of flasks you can serve.
You determine the appropriate gas flow rate using a pressure regulator (which you
supply) on the gas supply.
NOTE:
Gas supply should be regulated and it must never exceed 15 PSIG.
50 feet of 1/16-inch (ID) sterilizable silicone tubing is supplied with the kit. Filters may
be needed: 0.22μ syringe filters (which you supply) can be fitted to the individual
manifold ports to maintain a sterile barrier.
