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.

the unit.
4.1 Tools Required for Installation
To install the I-26/26R on an optional base and/or to stack I-26/26R units, the following
tools will be needed:
• Number 2 Phillips head screwdriver
• Level, ≥10-inch (25.4 cm)
• Two adjustable wrenches
• Forklift or other lifting equipment to lift more than 370 lbs (168 kg)
• Metal leveling shims
4.2 Leveling a Single Shaker
NOTE:
Do NOT use feet if you are stacking shakers or adding a base.
Make sure that the shaker is placed on a level surface and that all four feet are solidly on
the surface. If the shaker is not level, adjust the feet as needed to achieve leveling:
1. Immobilize the top lock nut against the unit with one wrench whenever you adjust
the foot, to keep the threaded stud from falling out.

New Brunswick Scientific Co., Inc. User’s Guide
2. With a second wrench against the flats of the threaded stud, just above the foot:
rotate clockwise to lower the foot or counter-clockwise to raise the foot.
3. Place a level on the top of the unit.
4. If necessary, make further adjustments by repeating all steps until the unit is level.
5. Fully load the shaker and do a test run at normal speed. Make additional leveling
adjustments if necessary.
NOTE:
The maximum foot height adjustment is ~ ¼ inch (6.4 mm). If a higher
adjustment is required, you will need to add metal shims.
4.3 Adding a Base
There are three bases available for your I-26/26R shaker(s). The height of the base
depends on whether you are installing one unit on the base, or stacking two or three units:
Table 1: Optional Bases
Number of Shakers Base Height
1 17 inches (43.2 cm) One 4-inch base & one 13-inch base,
bolted together at the factory
2 stacked 13 inches (33.0 cm)
3 stacked 4 inches (10.2 cm)
4.4 Preparing the Optional Base
1. Place the base on a sturdy (capable of bearing the weight of the combined base
shakers and shaker contents), level surface, making sure that all four corners are
solidly on the surface.
2. If the base is not level, place metal shims as needed under the base until it is level.
3. If you are mounting a single shaker, use the 17-inch base as shown in Figure 3b. Bolt
the shaker to the base using the hardware provided.

Figure 3b: Optional 17-inch Base
4. As shown in Figures 3a-b, depending on the height of your base, install the front side
braces and rear corner braces on the base with the hardware provided, matched to the
holes in the base.

4.5 Mounting the I-26/26R on the Optional Base
1. Using a forklift or lifter, raise the I-26/26R so that its back end is tilted toward the
rear of the base.
2. Remove all six feet from the bottom of the shaker. They will not be needed for
stacking, but you may want to keep them for future use.
3. With two assistants, each holding the shaker on one side, lower the unit onto the base,
rear panel first. Slowly and gently remove the forklift or lifter and lower the front of
the unit onto the base by hand.
NOTE:
Optional handles are available to facilitate maneuvering the shaker onto the
base. See Section 9.3.7 for details.
Figure 4: Mounting Shaker on Base
4. Using the ½-13 x 1¼-inch Allen head screws, ½-inch lock washers, and washers
provided, secure the rear of the I-26/26R to the corner braces in the base. With the
remaining ½-13 x 1¼-inch Allen head screws, ½-inch lock washers, and washers,
attach the front corner braces to the unit.
5. Attach the front corner braces to the base using the two sets of ½-13 x 1¼-inch Allen
head screws, lock washers, and washers provided, and secure as shown in Figure 5.

6. Make sure the shaker is level; add metal shims under the base as needed to level the
unit.
7. Fully load the shaker and do a test run at normal speed. Make additional leveling
adjustments if necessary.
