1 OVERVIEW

New Brunswick Scientific’s Innova 4200 Incubator Biological Shaker is a very versatile shaker 

for the biological research laboratory. The Innova 4200 provides a temperature-controlled 

environment that can be equipped with various accessories to adapt it for the culture of 

microorganisms, cell culture and hybridization. 

Automatic features include an interlock door that shuts off the shaker when the door is open, 

chamber temperature shutoff, and overload/unbalanced sensor that automatically limits the speed 

of the shaker when an unbalanced or overloaded condition is detected. Audible and visual alarms 

alert the user when the temperature or speed is out of range. 

Microprocessor controller with feedback controls the temperature and speed of the shaker. 

Temperature and speed setpoints are entered and changed using the membrane switch keypad. 

Setpoints and the actual values are displayed on the 3/8” (9.5 mm) bright LED display. The 

shaker operates continuously, or in a timed mode via a programmable timer for shaking periods 

of 0.1 hr–99.9 hrs. An audible and visual alarm indicates the end of a timed cycle. The triple 

eccentric drive is counterbalanced and provides horizontal plane rotary motion in 3⁄4′′ (19 mm) 

circular motion. A 1′′ (25.4 mm) model is also available. 

The Innova 4200 has a (0–5 Volt) analog chart recorder outputs for speed or temperature. 

The 4200 is stackable (up to two units), and accommodates routine laboratory accessories like 

Rollers, Magnetic Stirrers, Rockers, and Shakers. A wide variety of platforms and accessories 

are available for the Innova 4200.

#NOTE:

You can start or stop the shaker by pressing the START/STOP KEY. When 

starting, the unit will automatically return to the last function and setting. 

The alarm will be activated until the speed is within 5 rpm or the 

temperature is within 1.0°C of the setpoint. The alarm will not sound when 

the shaker is accelerating or the temperature is changing to satisfy a new 

setpoint. 

7.3 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 SELECT KEY until the function °C INDICATOR illuminates. 

5. Simultaneously press the Δ (up) and ∇ (down) KEYS. The SET and MAINT

INDICATORS will light. 

6. While the SET and MAINT INDICATORS are illuminated, use the Δ or ∇ KEY to set the 

display to the calculated Temperature Correction Value. 

#NOTE: 

The °C light will pulse rapidly for a short duration to indicate it is not 

operating in the factory default mode. It will pulse for a longer duration and 

less rapidly (with a frequency of approximately one second) to indicate 

temperature is more than one degree above or below setpoint.

After 10,000 hours of operation, the MAINT STATUS INDICATOR illuminates. 

See Section 8.1 to disable the maintenance indicator light. 

7.7 Using the Innova 4200 as a Quiescent Incubator 

The two stainless steel shelves can be used to incubate quiescent cultures. You should 

make sure that your cultures would not be susceptible to very slight vibrations that can 

occur when the shaker is running. If this is a concern, the culture should be tested prior 

to use. 

To install the shelves, perform the following: 

1. Verify that the ON/OFF POWER switch is OFF. 

2. Open the cabinet door. Remove any equipment or platforms from the cabinet interior 

that may interfere or obstruct mounting a shelf. 
27 

Innova 4200 • M1233-0053 User’s Guide 

3. There are four shelf mounting rails located on the side walls of the cabinet (see 

Figure 8 below). Once the desired shelf height is selected, insert one shelf bracket 

into the each of the shelf mounting rails, so that the flat side of the bracket is facing 

up. Ensure that each bracket is at the same level before installing the shelf. 

Figure 8: Shelf Detail 

4. Place the shelf on top of the brackets. Verify that the brackets are positioned inside 

the cutouts on each side of shelf , and the shelf and brackets are securely in place 

before mounting any equipment on the shelf.

5. Repeat steps if it is desired add another shelf to the cabinet. 

7.8 Reducing Dehydration 

Storing cultures in the 4200 for extended periods may dehydrate cultures. Cultures 

grown on agar or liquid cultures using very small volumes are most susceptible. 

Dehydration in the chamber can be limited in several ways: 

• Install the air deflector provided to protect Petri dish cultures from direct exposure to 

air currents. (See Section 7.9 below). 

• Place a container of water inside the chamber to rehydrate the air. 

• Seal the cultures if possible before they are placed in the chamber. 

• Limit the incubation time.

7.9 Air Deflector Installation 

An air deflector kit (M1233-9994) is provided for installation on a shelf, particularly if 

you are using Petri dishes. The deflector acts as a barrier to the direct air currents 

generated by the fan, sending the air to the roof of the chamber. This keeps the Petri 

dishes, or other items placed on the shelves, from drying out. 

To install the air deflector on the shelf: 

1. With reference to Figure 9 below, stand the deflector on the fan side of the shelf. 

2. Using the screws and washers provided, mount the deflector base to the shelf and the 

tapping plate underneath for support.

 WARNING!

 The following sections are ONLY for qualified Electrical & Service 

 Engineers, who will always disconnect the power cord before performing 

 any service on the shaker. 

7.12 Using Ancillary Equipment with the Innova 4200 

The Innova 4200 has a special internal AC socket that is used to power ancillary 

equipment such as magnetic stirrers, rockers, rollers and small shakers. 

In most cases, the equipment used will be light duty rockers or rollers. However, if 

heavier equipment is desired, the operator should verify that the stainless steel shelves 

supplied can support the load. 

In addition, be sure to verify that the equipment operating inside the Innova 4200 does 

not affect the stability of the unit. This is accomplished by operating the particular piece 

of equipment under the expected load and speed conditions. If the Innova 4200 vibrates, 

limit the load and/or speed conditions for the operation of the ancillary equipment. 

If the Innova 4200 is intended to be used as a shaker at the same time, both shaker and 

ancillary equipment should be run under expected load and speed conditions. If the unit 

vibrates, the shaker speed and/or the load should be reduced, or the Innova 4200 should 

not be used as a shaker at the same time the ancillary device is in operation. 

#NOTE:

It has been found that an Innova 2050 orbital shaker weighing 35 lb. 

(15.9 kg) could be operated inside the Innova 4200 at 250 rpm while the 

Innova 4200 is shaking at 250 rpm. 

The outlet is located inside the shaker chamber on the upper right side. It is important 

to note that this AC supply is the same as the main supply of your 4200. If your unit 

operates off a 115 volt supply, then any ancillary equipment you plug into the internal 

socket must also operate at 115 volts. 
31 

Innova 4200 • M1233-0053 User’s Guide 

7.12.1 Electrical Moisure-Proof Plug 

The AC socket (see Figure 11 below), with cover and mating plug (supplied) is designed 

to be used in humid environments. To use the socket, you have to connect the special 

male plug (supplied K0380–0871 with the unit) to the equipment that you use in the 

Innova 4200. If your equipment has a detachable power cord, you may want to obtain a 

different power cord to be used solely with the Innova 4200 shaker.
