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 80 C,
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 Scientific 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
Lid open
