22

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 2.54 cm (1 in) 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 10.3.

7.1 Platform Assemblies

The I-26/26R can be used with a New Brunswick universal, dedicated, or Sticky Pad
platform. Universal platforms accept a variety of clamps for flasks, test tubes, etc.
Dedicated platforms are supplied with clamps already installed. Sticky Pad platforms do
not have holes because they do not require clamps; the adhesive quality of the Sticky Pad
or Sticky Tape applied to the platform holds flasks in place.

Sticky Pad and Sticky Tape are options that are sold separately.

A platform is a separate item, not included with the shaker assembly, but which is
required for operation. (See Section 7.3 for details about installing and removing
the platform, and Section 10.3 for details about available accessories.)

7.2 Installation of Clamps

If you are not using a New Brunswick Universal Platform, skip this section. Flask
clamps purchased for use with universal platforms require installation. All New
Brunswick clamps are shipped complete with hardware. Clamps are installed by securing
the base of the clamp to the platform with the smaller Phillips head (+) screws supplied
with the New Brunswick clamps.

Clamps for 2- and 2.8-liter flasks are shipped with an additional girdle to keep the flasks
in place. We strongly recommend the use of this additional girdle because it keeps the
flask from spinning inside the clamp. The girdle is an assembly of springs and sections
of rubber tubing. One girdle is already in place on the clamp, the other is packed
separately. To install these double girdle clamps:

1. Place the clamp on the platform, aligning its mounting holes with holes on the
platform. Secure the clamp in place using the flat Phillips head screws provided
(#S2116-3051, 10-24 x 5/16-inch); see Figure 11b to help you identify them.

2. With the first girdle in place, as delivered, on the upper part of the clamp body (see
Figure 11a), insert an empty flask into the clamp.

3. After making sure the sections of tubing are located between the clamp legs, roll the
first girdle down the legs of the clamp as far as it can go. The tubing sections will
rest against the platform, and the springs will be under the clamp base.

4. Place the second girdle around the upper portion of clamp body (just as the first
girdle was initially). Make sure that its spring sections rest against the clamp legs,
while its rubber tubing sections sit against the flask, in between the clamp legs.

7.3 Installing/Sliding out Platform

The I-26/I-26R is delivered with the subplatform bolted in place on the bearing housing.
The addition of a platform is required for shaker operation.

Installing a platform of any variety is very easy:

1. Remove the two knobs and washers on the front of the subplatform.

2. Using the side handles of the platform (see Figure 12), place the platform on the
guide strips on the flat of the open door.

3. Push it toward the rear of the unit, aligning the bottom of the platform with the top of
the subplatform, and making sure the sides are squared up with the subplatform sides.

4. When it is fully inserted and mated to the subplatform, replace the washers and knobs
on the subplatform.

During operation, if the temperature of the chamber is more than 1.0C higher or lower
than the temperature setpoint, an alarm is triggered. This alarm consists of a flashing C

INDICATOR

achieves the set temperature.

8.7 Temperature Offset Calibration

The temperature probe and the temperature controller are calibrated together at the
factory. The temperature probe measures the temperature of the air at the probe’s
location, near the heat exchanger return vent. The controller uses the probe input to
adjust air temperature, up or down, to match the temperature setpoint.

Depending on various conditions within the chamber, such as flask placement and size,
the heat produced by growing organisms, heat losses due to liquid evaporation from
flasks, etc., the display temperature may differ from temperatures within the flasks
themselves.

If you wish to have the temperature display (“Indicated Temperature”) match the
temperature at a given point, or match the average of a series of points within the
chamber (“Actual Temperature”), proceed as follows:

1. Let the unit equilibrate at or near the desired temperature. Record the Indicated
Temperature.

2. Record the Actual Temperature.

3. Calculate the temperature correction value: Actual Temperature – Indicated
Temperature = Temperature Correction Value.

4. Press the
