Innova Shakers are warranted by New Brunswick Scientific Co., Inc.
for two years or 10,000 hours of actual shaker use, whichever comes later.
This warranty covers parts and labor for the entire machine, with the exception
of glassware and its contents. This warranty covers faulty components and
assembly, and our obligation under this warranty is limited to repairing or replacing
the shaker or part thereof which shall, within two years after date of shipment or
10,000 hours of operating time, prove to be defective after examination. This
warranty does not cover any loss of time, materials, biological or biochemical by-
products caused by any work interruption resulting from shaker failure, nor does it
extend to any Innova Shaker which has been subjected to misuse, neglect, accident
or improper installation or application. In addition, the warranty does not apply to
any Innova Shaker that has been repaired or altered outside the NBS factory without
prior authorization from New Brunswick Scientific. For a period of two years (or
more) after the shipment date, the Innova warranty will be in effect as long as
the shaker has not been in operation for a total of 10,000 hours. After the
10,000 hours of operating time have elapsed, the Innova warranty may
still be in effect, as long as the two-year minimum warranty period
has not been reached. Operating time is based on actual usage
of the shaker, as determined by the shaker’s internal
electronic clock. Any tampering or alteration of
the clock will void the 10,000-hour
warranty.

2.1 General Description
The Innova 3100 is a shaker that incorporates a triple eccentric counterbalanced drive
to provide horizontal plane rotary motion in a ½ inch (12.7 mm) circular orbit. A
Proportional/Integral (PI) microprocessor controller with instantaneous digital
feedback controls the speed over a range of 25-400 RPM. It also provides temperature
control over a range of 5°C above ambient to 99.9°C. For lower temperatures an
optional water bath cooling coil is available.
The shaker may be operated either continuously or in a timed mode via a
programmable timer for shaking periods of 0.1 hour to 99.9 hours.
The Innova 3100 is equipped with audible and visible alarms which are activated
when an alarm condition exists as follows:
•The end of a timed run
•Deviations of shaking speed or temperature outside of tolerance limits
•Low water level
•Water overflow
A wide variety of platforms can be used with the Innova 3100. Dedicated platforms
are available for a variety of flask sizes. A Universal platform and test tube racks are
also available. (See Chapter 7 for accessories.)
The Innova 3100 has a built-in water level control system which is infinitely
adjustable over a wide range. To compensate for evaporation, water is automatically
replenished to the preset level.
Additionally, the Innova 3100 has analog outputs for a chart recorder that will record
speed and/or temperature. See Chapter 5 for recorder adaptation.
See Figures 1 and 2 below for the front and rear views of the Innova 3100.

2.2 Universal Power Capability
A voltage selector switch is used to select the appropriate voltage. This universal
system adapts to worldwide power requirements. Voltage has been set prior to
shipment. Innova shakers are available in 100V, 120V, 220V and 240V versions, and
accommodate both 50 and 60 Hz frequencies.
WARNING!
It is critical that you check the voltage settings before
you plug the unit into a power source. See Section 3.2.

2.3 Control Panel
The control panel (see Figure 3 below) is located on the front of the instrument. It serves as
the operator interface. The keypad has four keys marked START/STOP, ∆, ∇, and
SELECT. A three-digit LED display provides numeric values as well as some letter codes.
There are four function indicators and four status indicator lights on the control panel as
well. A general description of the display, user interface keys and indicators follows.
For operation of the control panel, see Chapter 4.
2.3.1 LED Display
The Innova control panel has a 3-digit LED display. During normal shaker
operation, the display will indicate:
•Shaker status (on/off)
•Shaking speed
•Setpoints
•Hours remaining (timed run)
•Measured temperature
•Low water level
Figure 3: Control Panel

Innova 3100 M1231-0050 User’s Guide
2.3.2 User Interface Keys
•START/STOP
This key is used to start or stop the shaking motion. It will also activate or
stop the timer when a timed run is desired.
•SELECT
This key is used to change the displayed parameter.
•∆, ∇
These keys are used to adjust the setpoint of a displayed parameter up or
down. They also allow the user to enter the SET mode for setpoint
changes.
2.3.3 Status Indicator Lights
There are four status indicator lights, located to the left of the LED display:
•MAINT
Lights to indicate that 10,000 hours have elapsed since the unit was last
serviced. Accumulated running time is internally monitored and may be
displayed as a guideline.
•SET
Indicates that the shaker is in the SET mode, that setpoints are being
displayed and that they can be altered.
•TIME
Indicates that the timer is in operation. Innova shakers can be programmed
to run for a preset time from 0.1 hour to 99.9 hours. The timer can be
disengaged to reset without stopping an ongoing run.
•MUTE
Indicates the status of the audible alarm. When the MUTE indicator is
illuminated the audible alarm device is disabled.

New Brunswick Scientific User’s Guide
2.3.4 Function Indicator Lights
There are four function indicator lights, located to the right of the LED display.
They indicate the current parameter being displayed:
•RPM Revolutions per minute
•HRS Time remaining
•°CCurrent Temperature
•* Low Water Level
2.4 Platform Assemblies
The Innova 3100 can be used with a wide variety of NBS 12 inch x 16.5 inch
platforms which will accept a variety of clamps for flasks and test tubes.
Additionally, a subplatform is available to adapt half platforms for flasks and test
tubes used on the NBS Model G86 Aqua Therm Water Bath Shaker.
2.5 Cooling Coil Option
The Innova 3100 can be ordered with a cooling coil factory-installed. The cooling
coil provides the ability to operate at temperatures below ambient.
2.6 Accessories & Options
The following accessories are available for use with your Innova 3100:
•Gable Cover (plexiglass or stainless steel).
•Portable cart or space saving dolly.
For operation below ambient temperature, the following kits are available for retrofit
(by an NBS-authorized service technician only):
•Cooling coil kit.
•Coolant Circulating System.
