The Excella® E-24/24R Benchtop Incubator Shakers use a UniCentric™ counter-balanced drive
mechanism. They provide horizontal plane rotary motion in a ¾-inch (1.9 cm) diameter circular
orbit. A Proportional/Integral (PI) microprocessor controls the speed and temperature over the
entire range.
The incubated and refrigerated E-24R operates from 15ºC below ambient (with a minimum
setpoint of 4ºC) to 60
C, and the incubated E-24 from 7ºC above ambient to 60ºC. Both these
ranges depend on relative humidity and other ambient factors. Ambient temperature is measured
one meter from the front of the unit.
Erlenmeyer flasks, 2.8-liter Fernbach flasks, and a wide variety of tubes and plates can be
accommodated using the New Brunswick shaker accessories described in Section 9.
The E-24/24R 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, while the temperature is maintained
at its setpoint.
For safe operation, the E-24/24R shakers are designed with a safety switch that automatically
stops the shaker mechanism when the lid is opened.
Both the E-24 and the E-24R are equipped with visual and audible alarms that alert the user to
the following conditions:
The end of a timed run
Deviations from speed setpoint (5 minutes after lid is closed)
Deviations from temperature setpoint (5 minutes after lid is closed)
Power failure
Lid open
To accommodate customer needs, a wide variety of platforms can be used with the Excella
E-24/24R:
Universal platforms are the most flexible, providing hole patterns for flask clamps,
test tube racks and other accessories.
Dedicated platforms are supplied with flask clamps attached; they are designed solely
and expressly for this purpose.
