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.

This Manual is intended to provide the user with a complete understanding of
how the Innova 4300 Digital Incubator Shaker operates, its basic components,
and information about preventative maintenance and service issues. This
Manual also includes a complete guide to the installation and operation of the
Innova 4300.
The manual is divided into three basic sections. Chapters 1-2 provide an
overview of the Innova 4300 and all of its features and options. Chapters 3-4
detail the set-up, installation and operation of the instrument. Chapter 5
outlines troubleshooting and service procedures, which should be utilized only
by a qualified service engineer. Chapters 6-9 provide additional details of
interest: specifications, lists of accessories, drawings and ordering
information. Finally, Chapter 10 is an index to important terms used in the
manual.
It is recommended that you completely familiarize yourself with this manual
prior to actually operating the Innova 4300.
The Innova 4300 Digital Incubator Shaker will provide you with the reliable and
maintenance-free operation which is characteristic of all NBS shakers. The Innova 4300 is

2.1 General Description
The Innova 4300 shaker incorporates a triple eccentric counterbalanced drive to
provide horizontal plane rotary motion in a 1” (25.4 mm) circular orbit. A
Proportional/Integral (PI) Microprocessor controller with instantaneous digital
feedback controls the speed over a range of 25-500 RPM. It also provides temperature
control over a range of 5°C above ambient to 60°C. The internal chamber is 34¾
inches (88.3 cm) wide, 22¼ inches (56.6 cm) deep, 19¼ inches (48.9 cm) above the
platform and will accept flasks up to 6 liters. It is equipped with a foot-pedal lid lift.
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 4300 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
A wide variety of platforms can be used with the Innova 4300. Dedicated platforms
are available for a variety of flask sizes. A Universal platform and test tube racks are
available. (See Chapter 7 for accessories.)
Additionally, the Innova 4300 has analog outputs for a chart recorder that will record
speed and/or temperature. (See Chapter 5 for recorder adaptation.)
See Figures 1, 2 and 3 for the front, rear and side views.

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 and
accommodate both 50 and 60 Hz frequencies.
WARNING!
It is critical that you check the voltage setting before you
plug the unit into a power source. Make sure the voltage
set on the voltage selector switch (see Figure 2) matches
the voltage specified on the CAUTION label located over
the power cord connection on the rear panel. For details,
see Section 3.2.

2.3 Control Panel
The control panel (see Figure 4 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 display on the Innova control panel is 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
• “Lid” (cover open & shaker operation stops)
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
Remains lit after 10,000 hours of use. Accumulated running time is
internally monitored and may be displayed as a guideline.
• SET
Indicates that the shaker is in the SET mode and setpoints are being
displayed and 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 hr. to 99.9 hrs. without stopping an
ongoing run. The timer can be disengaged or reset.
• MUTE
Indicates the status of the audible alarm. When the MUTE indicator is
illuminated the audible alarm device is disabled.

INNOVA 4300 •M1193-0050 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
• Hours Time Remaining
• °C: Temperature
2.4 Platform Assemblies
The Innova 4300 can be used with a wide variety of NBS 18 inch x 30 inch (46 cm x
76 cm) platforms which will accept a variety of clamps for flasks and test tubes (see
Chapter 7 for accessories).
2.5 Quick-Change Platform Kit
This easy-load accessory enables the user to snap in platforms without tools or
hardware. Recommended for speeds up to 400 RPM.
2.6 Triple Eccentric Drive
The Triple Eccentric Drive (see Figure 5) used in the Innova Shakers employs the
same proven technology which has driven New Brunswick Scientific’s shakers for
over 30 years.
This drive mechanism utilizes a counterweight system to stabilize the rotary motion
produced during operation. When the workload moves in one direction, opposing
forces are generated to stabilize the shaker. This action will help eliminate the
problem of “walking” which may occur with less precisely balanced instruments.
Vibration is minimized and the life of the unit is extended.
