A Good Shaker Design is Paramount

Engineering is in our culture and these laboratory shaker units are an excellent example. Each unit has a built in timer for timed laboratory procedures and advanced speed control for mixing reproducibility. The bright OLED display is housed under tempered glass for protection and visibility. Each unit has familiar dial controls for adjusting the speed and timer features. The real time speed is displayed on the screen to confirm correct operation. The setpoint is easy to change and these units have built in alarms and safeties for years of service.

When it Comes to Laboratory Mixers, Choice is Good!

No lab is the same and protocols can change. Therefore, Four E’s offers four types of motion in our shaker line. The Orbital and Linear Shaker can easily switch between two types of mixing motion. An orbital motion is great for standard Erlen Myer Flasks, shaker flask, or baffled shaker flask and bacterial cultures such as yeast or E. coli. The reciprocating motion of the linear shaking is excellent for staining, washing blots and general laboratory mixing. The 2D rocker is also good for staining and cell culture, especially with wave type single use cell culture bags. Our 3D Wave Nutating Mixer uses the familiar corner tipping method to agitate samples and cultures. The Belly Type shaker is adjustable and can operate in a flat orbital mixing motion or a 3D Wave Motion. Four E’s Shaker line has your laboratory mixing needs covered.

Frequently Asked Questions

Everything you need to know about product and billing. Can’t find the answer you are looking for? Please write your question to us at

Does the Unit Come with a Warranty?

Yes, all Four E’s Laboratory Shakers, Rockers, and Rotators have a two-year warranty.

What unit is best for Western Blotting?

We find that the Orbital motion works well for Western Blotting and Hybridization but we have seen customers using 2D units for gels.

What unit should I use for bag type cell culture?

The 2D rocker is best for using a bag type culture to ensure proper gas exchange with the headspace.

Can the units be used in an Incubator?

Yes, the shakers can be using in a standard incubator.

How does the Universal Bar attachment work?

The universal bars are adjustable with thumbscrews on the side of the platform. This allows positioning flasks on the platform and trapping the neck of the flask with the bar. The bars can also be removed if you would like to place the samples directly on the platform. Dedicated flasks holders are available for 25ml, 50ml, 100ml, 250ml, and 500ml shaker flasks.

What does Nutating mean?

Nutating is a Latin word that means swaying. It is used to describe the motion of the platform as it tilts around a center point of a fixed height. This is great for general purpose low foaming mixing or gas exchange in cell cultures.

Can you repair a damaged unit?

If a unit is dropped or damaged we can repair the item in our New Jersey facility. Onsite repair may be available based on location.
