Infinity Rockers


Infinity Rocker™

The Long-Life Laboratory Platform Rocker … accurate programmable tilt platform

The last rocker you will ever need to buy! The Infinity Rockers are designed with constant, heavy-duty use in mind, and they will last for many years – unlike all those rockers with one-year warranties. Ultra quiet, they are ideal for many applications including: mixing, gel staining and destaining, blotting, cell culture, hybridization, washing, etc…

Two Platform Sizes

Infinity Rockers come in models with: 11 x 14 and 8 x 9 inch (28 x 36 and 20 x 23 cm) platforms.

Stacking Trays

Removable Tier-2 stacking trays double the support surface area. The trays just snap onto the platform and their spring loaded legs hold them securely in place.

5 Year Warranty

We offer a 5 year warranty because Infinity Rockers are solidly built in the USA. The rugged construction includes heavy duty chassis and platforms. Long life brushless motors drive the rocking. These rockers are designed to run for many years of continuous use.

Digital Speed Control

The Infinity Rockers have a microcontroller to accurately control the speed. The speed will remain constant, even as heavy items are added or removed from the platform. And the rocking can be paused and resumed by flipping a switch. Rocking speed can be set from 6 rock cycles an hour (0.1 per minute) to 80 per minute in increments of 1 RPM. And rocking can be even slower, or even be stationary with punctuated periods of rocking with custom programs, as described below.

Extremely Quiet Operation

The Infinity Rockers are incredibly quiet due to their high quality motor and vibration isolation mounts inside the unit.


Available soon. Programmable rockers in which the platform can be set to pause at a particular angle, vary rocking speed, etc. For example, the platform can move slowly in one direction, pause, and then return quickly. Or it can be set to have very long pauses between cycles, such as rock for just 3 minutes once a day. Several customers use our rockers for microfluidic applications. For applications such as viral transduction or plasmid transfection, you may want short periods of gentle rocking for mixing, separated by 30 minute stationary periods to allow transduction to occur. And rocking can be asymmetric, meaning fast in one direction, and slowly back, such as for mixing microliter volumes to avoid depletion zones during hybridization.

Custom Sizes

Get a rocker that fits your needs! Upon request, rockers can be made to accommodate specific platform sizes and weights.

Rugged Construction

These very sturdy (and quiet!) rockers sport heavy-duty construction. A top grade brushless motor drives the rocking and ensures very long life.

Tilt Angle Adjustment

Loosen the screw on the back of the rocker and slide the linkage toward the center (to decrease the tilt) or perimeter (to increase the tilt) and then tighten the screw.

Stacking Trays and Additional Platforms

Tier-2 stacking trays are available for all Infinity Rocker models. These rugged trays double the support surface area of single platform rockers. They are constructed of heavy gauge ABS plastic for ruggedness and have a textured neoprene rubber pad.
You can place a stacking tray on a platform, as pictured on an Infinity Rocker Pro, or remove it when desired, without any tools. The spring loaded legs hold the stacking tray in place. There are 4 inches (10 cm) of clearance above the main platform. 


Infinity Rocker™ FAQs


Will these rockers work with different voltages (in different countries)?

Yes. The rocker uses 12V DC supplied by a small external power supply that plugs into a wall outlet. Next Advance will supply the appropriate power supply for the local power and wall outlet configuration.

What is the maximum load?

The rocker can handle 11 lbs. (5 kg).

What is the range for the tilt angle?

The amount that the rocker platform tilts back and forth can be adjusted from as little as +/- 1 degree to as much as +/- 18 degrees.

What is the rocking rate?

For Infinity Rockers, the rocking rate can be as slow as barely moving to a maximum speed of 80 cycles per minute (160 rocking motions per minute).

Can I use these rockers in incubators or cold rooms?

Our rockers can operate in incubators or cold rooms (down to 4°C) if the temperature is kept constant and the humidity is not excessive. Temperature swings which cause condensation will damage the electronics and void the warranty. In fact, the electronic circuitry includes additional heat sinks to ensure reliable operation at elevated temperatures.


How do I adjust the tilt angle?

To adjust the angle, use a flat blade screwdriver to loosen the labeled screw on the rear of the instrument, slide the linkage to the desired position, then tighten the screw.

How do I adjust the rocking rate?

You can turn the knob on the front of the instrument to adjust the rocking speed.

Can I clean the rubber mat?

Yes. You can remove the rubber mat from the platform and clean it with soap and water. Let it dry before placing it back on the platform.
