The I-26/26R large stackable incubator shakers are large capacity orbital shakers that
utilize a triple eccentric counter-balanced drive mechanism. They provide horizontal
plane rotary motion in a 1-inch (2.54 cm) diameter circular orbit. A Proportional /
Integral (PI) microprocessor controller with instantaneous digital feedback controls the
speed over a range of 25-400 rpm.
The I-26 provides temperature control from 5
°
C above ambient to 60
°
C. The refrigerated
I-26R assures temperature control down to 15
°
C below ambient, with a minimum
setpoint of 4
°
C. Ambient temperature is measured one meter from the front of the unit.
The shakers may be operated either continuously or in a timed mode via a programmable
timer for shaking periods of 0.1 to 99.9 hours.
For safe operation, the I-26/26R models are designed with a safety switch that
automatically stops the shaker mechanism when the door is opened.
The I-26/26R is equipped with visual and 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
•
Door open
•
Unstable operating conditions (tilt switch—visual alarm only)
A wide variety of slide-out platforms can be used with the I-26/26R. Dedicated
platforms and universal platforms are available for a variety of flask sizes. Test tube
racks, microtiter plate holders, and test tube rack holders are also available (a universal
platform is needed for all test tube racks and holders). For further information on these
accessories, see Section 9.3.
