The Excella
®
E-25 Classic Incubator and E-25R Classic Refrigerated Incubator Shakers are large
capacity shakers utilizing a UniCentric single eccentric counterbalanced drive to provide
horizontal plane rotary motion in a 2.54 cm (1 in) circular orbit. A Proportional/Integral (PI)
Microprocessor controller with instantaneous digital feedback controls the speed over a range of
50-400 rpm.
The E-25 provides temperature control over a range of 7C above ambient to 60C, while the
E-25R provides temperature control over a range of 15C below ambient (minimum 4C) to
60C. Ambient temperature is defined as the temperature within one meter of the shaker.
The shakers may be operated either continuously or in a timed mode via a programmable timer
for shaking periods of 0.1 hr. to 99.9 hrs.
For safe operation, both the E-25 and E-25R are designed with a safety switch that automatically
stops the shaker mechanism when the lid is lifted.
In addition, the Excella E-25 and E-25R are equipped with visual and audible alarms that alert
the user to the following conditions:
The end of a timed run
Deviations of shaking speed
Deviations of temperature setpoint
Power failure
Lid open
A wide variety of platforms can be used with the E-25 or E-25R. Dedicated platforms are
available for a variety of flask sizes. Universal platforms, utility trays, utility carriers and test
tube racks are also available.
