The infinity Rockers (IR)
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
/
Three Platform Sizes
Infinity Rockers come in models with: 11 x 14, 8 x 9, and 20 x 16 inch (28 x 36, 20 x 23, and 51 x 41 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.

Triple and Quadruple Deckers
Stack-3 and Stack-4 versions provide 3 or 4 times as much capacity. The 3 or 4 platforms each tilt about their own axis. 

4 Year Warranty
We offer a 4 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.

Programmable
We can provide custom rocking programs for your Infinity Rockers upon request at checkout for an additional cost (limitations apply for XL). 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.
