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 7
C above ambient to 60C, while the
E-25R provides temperature control over a range of 15
C below ambient (minimum 4C) to
60
C. 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.
