Innova 2300 Orbital Shaker Overview

The New Brunswick Innova 2300 was designed for laboratories requiring more capacity and mechanical durability than a compact benchtop shaker can provide.

Its 18 x 30-inch platform provides ample space for flask clamps, test tube racks, microplate racks, and other shaker accessories. A laboratory can configure a universal platform for mixed vessel sizes or install a dedicated platform when maximum capacity for a single flask size is required.

The unit's low-profile body measures only about 6.4 inches high, allowing it to fit beneath shelving or inside suitably sized environmental chambers.

This combination of a large platform and relatively compact chassis makes the Innova 2300 useful both as an open-air laboratory shaker and as the agitation component of a temperature-controlled experimental system.

New Brunswick Innova 2300 Key Specifications

Common Applications

The New Brunswick Innova 2300 is well suited for microbial culture, bacterial and yeast cultivation, recombinant protein expression, fermentation research, media agitation, cell suspension work, biochemical mixing, plasmid preparation, protein production, seed culture expansion, and general laboratory mixing.

The large 2-inch orbit makes this particular configuration especially attractive for laboratories working with larger culture vessels where increased fluid movement and oxygen transfer are desirable.

Ideal Laboratory Types

The Innova 2300 is a strong fit for biotechnology companies, pharmaceutical research laboratories, microbiology facilities, molecular biology laboratories, fermentation and bioprocess groups, university research laboratories, contract research organizations, protein-expression laboratories, industrial R&D groups, and other facilities performing routine or continuous flask-based shaking.

Its large platform also makes it attractive for shared laboratories that need a single orbital shaker capable of supporting a wide variety of vessel sizes.

2-Inch Orbit for Large-Flask Shaking

This Innova 2300 is configured with a 50.8 mm / 2-inch circular orbit.

Orbit diameter is an important consideration when choosing an orbital shaker because it affects fluid movement inside the flask.

A larger orbit can produce strong bulk fluid motion at lower rotational speeds and is especially useful with larger vessels such as:

• 1 L Erlenmeyer flasks

• 2 L Erlenmeyer flasks

• 2.8 L Fernbach flasks

• 4 L flasks

• 5 L flasks

• 6 L flasks

For microbial cultivation and fermentation-related applications, this can promote effective mixing and gas exchange while allowing larger culture volumes to be processed on one platform.

Why the 2-Inch Innova 2300 Is Limited to 300 rpm

New Brunswick manufactured the Innova 2300 in both 1-inch and 2-inch orbit configurations.

The two versions do not have the same maximum operating speed.

The 1-inch-orbit Innova 2300 operates from:

25 to 500 rpm

The 2-inch-orbit Innova 2300 operates from:

25 to 300 rpm

The larger orbital diameter generates greater mechanical movement for each revolution, which is why the manufacturer specifies the lower maximum speed.

This distinction is important when replacing an existing shaker or reproducing a validated culture protocol.

Large 18 x 30-Inch Platform

The Innova 2300 uses an 18 x 30-inch platform, providing significantly more usable shaking area than many compact orbital shakers.

New Brunswick offered both universal and dedicated platform configurations.

A universal platform allows different flask clamps and accessories to be installed simultaneously, making it useful for laboratories that frequently change applications.

A dedicated platform is optimized around one flask size and can generally accommodate more vessels because clamp placement is optimized at the factory.

Flask Capacity with a Universal Platform

According to manufacturer documentation, the 18 x 30-inch universal platform can accommodate maximum balanced configurations of approximately:

Actual capacity depends on the platform, clamp arrangement, flask geometry, load distribution, and installed accessories.

Dedicated Platform Capacity

For laboratories using only one flask size, New Brunswick also offered dedicated platforms with pre-positioned clamps.

Dedicated platform capacities include configurations for up to approximately:

108 x 50 mL flasks
60 x 125 mL flasks
40 x 250/300 mL flasks
24 x 500 mL flasks
15 x 1 L flasks
12 x 2 L flasks
6 x 2.8 L Fernbach flasks
6 x 4 L flasks
4 x 6 L flasks

This makes the Innova 2300 particularly useful for laboratories running repetitive production or culture protocols with one standardized vessel size.

Shaking Large Erlenmeyer Flasks

The ability to accommodate flasks as large as 6 liters is one of the Innova 2300's most important advantages over smaller benchtop orbital shakers.

Large-flask capability is valuable for:

Microbial seed cultures
Recombinant protein expression
Fermentation preparation
Bioprocess development
Culture scale-up
Media preparation
High-volume suspension mixing

For laboratories transitioning from small shake-flask experiments toward larger bioreactor or fermentation processes, the Innova 2300 can serve as an effective intermediate-scale culture platform.

Microbial Culture & Protein Expression

Orbital shaking is widely used for growing bacteria and yeast because agitation improves both suspension uniformity and gas exchange between the culture medium and flask headspace.

The Innova 2300's large platform makes it possible to run multiple cultures simultaneously or use large flasks for increased culture volume.

This can be particularly valuable for recombinant protein workflows in which bacterial or yeast cultures must be expanded before cell harvesting, cell disruption, centrifugation, protein purification, chromatography, and downstream analysis.

Laboratories can therefore use the Innova 2300 as part of a broader sample-processing workflow that includes refrigerated centrifuges, superspeed centrifuges, incubators, refrigerators, and ultra-low freezers.

Counterbalanced Eccentric Drive

New Brunswick built its Innova platform shakers around a counterbalanced eccentric drive system designed to produce consistent orbital movement while minimizing unwanted vibration.

The drive uses permanently lubricated ball bearings and is powered by a brushless DC motor.

This design is particularly important on a large-platform shaker because the shaker may need to move multiple liters of culture media continuously for hours or days.

Smooth drive performance helps maintain stable shaking while limiting vibration transmitted to the laboratory bench or surrounding equipment.

Brushless DC Motor

The Innova 2300 uses a 1/8 HP brushless DC motor.

Brushless motors eliminate the carbon brushes found in conventional brushed motors, reducing one source of mechanical wear and routine maintenance.

For laboratories running long-duration cultures or operating a shaker continuously, a durable low-maintenance motor system can be especially valuable.

Digital Speed Control

A microprocessor-based proportional/integral control system regulates shaker speed.

The selected speed is shown on the digital LED display in 1 rpm increments, with manufacturer-specified control accuracy of approximately ±1 rpm.

Consistent agitation is important in biological culture because changes in orbital speed can influence oxygen transfer, mixing, cell growth, culture density, protein expression, and experimental reproducibility.

Digital control therefore provides an advantage over older mechanically controlled laboratory shakers.

Programmable Timer & Continuous Operation

The Innova 2300 can operate either continuously or for a programmed duration.

The digital timer supports shaking periods from approximately 1 minute through 99.9 hours.

When a timed run ends, the shaker stops and activates a status indication.

For long-duration cultures or routine mixing, the timer can be deactivated and the shaker operated continuously.

This flexibility makes the same shaker useful for both short mixing procedures and overnight or multi-day culture applications.

Audible & Visual Alarms

The Innova 2300 includes self-diagnostic alarm features intended to alert operators to important changes in operating conditions.

The system provides audible and visual notification if shaker speed deviates by more than approximately 5 rpm from the setpoint.

An alarm is also generated when a timed run expires.

The audible alarm can be disabled when appropriate while visual status indications remain available.

Automatic Restart After Power Failure

For long-duration experiments, unexpected power interruption can compromise cultures if the shaker remains stopped after power is restored.

The Innova 2300 includes automatic restart capability.

Operating setpoints are retained in nonvolatile memory, allowing the unit to resume operation following an unintended power interruption.

A flashing LED indicates that an interruption occurred so laboratory personnel can determine whether the event could have affected the experiment.

Use in Warm Rooms, Cold Rooms & Environmental Chambers

The Innova 2300 is an open-air orbital shaker rather than an incubated shaker.

However, New Brunswick designed the platform shaker for operation in ambient conditions and compatible controlled environments.

The manufacturer specifies an operating ambient range of approximately:

0°C to 60°C

with relative humidity up to approximately 90% non-condensing.

This means laboratories can potentially operate the shaker in a compatible cold room, warm room, environmental chamber, or large laboratory incubator when temperature-controlled shaking is required.

Environmental conditions and equipment clearances should always remain within manufacturer specifications.

Innova 2300 vs. Incubated Shakers

The Innova 2300 provides orbital agitation but does not independently control temperature.

An incubated orbital shaker combines shaking with a heated enclosure, while refrigerated incubated shakers can provide both heating and cooling.

The Innova 2300 may be preferable when the laboratory already has a temperature-controlled room, ambient-temperature shaking is sufficient, a large external environmental chamber is available, maximum platform access is desirable, or large flasks are routinely used.

An incubated shaker may be preferable when precise self-contained temperature control is required.

Innova 2300 vs. Smaller Orbital Shakers

Compact orbital shakers can be excellent for small flasks, microplates, tubes, and routine mixing, but they typically have much smaller platforms.

The Innova 2300's 18 x 30-inch platform allows much larger culture loads.

It is particularly attractive when a laboratory needs to process multiple 250 mL or 500 mL flasks, several 1 L or 2 L flasks, Fernbach flasks, or 4 L to 6 L vessels.

Rather than operating several smaller shakers, one Innova 2300 can provide substantial platform capacity.

Innova 2300 vs. Innova 2350

The Innova 2350 is the larger sibling of the Innova 2300.

The Innova 2300 uses an 18 x 30-inch platform, while the Innova 2350 uses a 24 x 36-inch platform.

The 2350 therefore offers greater total flask capacity but also occupies more laboratory space.

For laboratories that need high flask capacity while retaining a manageable benchtop footprint, the Innova 2300 provides an excellent middle ground.

Shipping & Installation Considerations

At approximately 108 lb., the Innova 2300 is substantially heavier than a small benchtop mixer and should be installed on a sturdy, level laboratory bench or other surface capable of supporting both the shaker and the loaded platform.

Adequate clearance should be provided around the moving platform.

The shaker should be leveled and positioned so that a fully loaded platform cannot contact walls, shelving, other instruments, or laboratory fixtures during operation.

Large flasks and high shaking loads should always be distributed evenly across the platform.
