Laboratory shakers are a critical piece of equipment found in almost every lab designed to agitate, mix, or blend samples and solutions in test tubes, Erlenmeyer flasks, beakers, and other various glassware.

Shaker devices are also referred to as rockers, rotators, vortexers, or vortex mixers. However, they differ somewhat from mixers. Rather than mix, shakers apply different styles of motion, such as rotating, rocking, reciprocating, and orbiting to homogenize ingredients and achieve results. 

Shakers are an ideal device for many fields of study and development, including chemistry, biochemistry, molecular biology, clinical diagnostics, and cell culture and analysis. They are designed to deliver quality performance and accuracy, provide reliable sample preparation of liquids and suspensions, and ensure reproducible results. 

These machines have been a necessary part of experimentation, cell growth, and sample preparation for as long as scientists have understood the impact of motion on a substance. While choosing the right shaker can be a daunting task, there are a number of ways to help narrow the field. Without the proper instrumentation, your laboratory’s research can suffer.

Shaker Types, Applications, & Price

Each type of shaker has different capabilities and configurations, and comes in a range of sizes, including benchtop, stackable, and floor models.

It is important to consider what experiments you wish to perform and which style of motion those experiments require.

Some other factors to consider include speed range, accuracy, temperature, and load capacity of the vessel used. A few of the many lab shaker styles include:


Benchtop orbital shakers move at varying speeds in a circular orbit, making them ideal for tasks like bacterial cell growth, studies of dissolution, washing blots, and staining electrophoresis gels. Their design allows for minimal vibration on benchtops, and generates less heat than other types of motion.

Digital orbital shakers have many applications in the field of molecular biology, but are also suitable for simple preparations like washing blots and general mixing.



Reciprocal shakers produce two different types of motion: side-to-side or back-and-forth. They are most commonly used for mixing samples inside of Erlenmeyer flasks, separation funnels, and other glassware for many different applications. The level of mixing can range from gentle to intense. nnThese shakers can be used for many different applications: gentle swirling, intense mixing or homogenizing, and even dry sieving or sifting.

There are various types of reciprocal shakers available, which are used to achieve different results. Some of the models include linear reciprocal shakers, rocker arm shakers, long stroke reciprocal shakers, and short stroke reciprocal shakers. nnDepending on the model and manufacturer, you’ll have a number of configuration options available, including volume capacity, speed, temperature control, and more.



An incubator shaker, as the name implies, is a mix between two devices. This device will incubate a sample while simultaneously shaking it. Much like an orbital shaker, the shaking incubator can employ orbital motion to a sample while also promoting cell growth and cell aeration through temperature control and motion.

Shakers that are capable of controlling environmental factors are often referred to as refrigerated incubator shakers, and have a range of 20°C below ambient temperature to around 80°C above ambient temperature.

The shaking motion provided by refrigerated incubator shakers introduces oxygen and nutrients evenly around the culture, and the temperature control prevents any fluctuations that may damage the sample. They are ideal for the growth of cells in tissue cultures and bacterial cultures.



A platform shaker can be considered a type of catchall term for laboratory shakers, because they are capable of different styles of agitating that include orbital, rocking, and rotating.

Equipped with a table board that moves horizontally, these shakers are quite versatile, since they can easily be moved around the laboratory. This allows you to treat the shaker like an open-air shaker or an incubator shaker.

The speed control, load capacity, and size of the platform of the shaker varies, as does the shape and texture. The style of agitation can also change from model to model, so it is important to know exactly what your requirements are. Platform shakers are the most common type of shaker.



The vortex shaker was the invention of the Kraft brothers, while working for Scientific Industries. Also known as a vortex mixer or vortexer, it works by oscillating a sample in a circular motion, creating a turbulent flow much like a vortex. This works similar to magnetic stirrers, but without the aid of a stirring rod, and at much faster speeds.

In order to mix reagents used in an assay or diluents in an experimental sample, high speeds are required. The use of high-speed mixing can also suspend cells. However, it is different from a centrifuge.

On a vortex mixer, the liquid is swirling inside a test tube, while in a centrifuge, the test tubes containing the liquid are held in a fixed position inside of the centrifuge’s rotor, and the rotor spins inside of the device, producing centrifugal force perpendicular to fixed axis of spin.


Shaker Leases to Fit Every Lab’s Need

Sample mixing is an essential part of many preparative steps during research, making lab shakers a vital part of any facility.

Whether you need to vigorously mix or homogenize substances, or gently shake them to achieve the desired results, having the proper laboratory equipment with the exact shaking speed abilities you need is a must.

However, sometimes capital expenditures can add up, making purchasing equipment more difficult than you’d expect.

With our leasing program, you won’t have to worry about the upfront costs of purchasing, making it easier to acquire all the equipment you need while freeing up much needed monthly capital for other aspects of your lab. 

We also include preventative repair and maintenance coverage, so you can have peace of mind and minimize your downtime. Reach out today to learn more about our leasing program and receive a laboratory shaker lease estimate.

Operating Lease

This off-balance sheet financing structure provides three options at the end of the term. The lessee has the option to return the equipment to the lessor, renew at a discounted rate, or purchase the instrument for the fair market value. Monthly payments are also 100% tax deductible which yields additional monetary savings.


If you recently bought equipment, Excedr can offer you cash for your device and convert your purchase into a long-term rental. This is called a sale leaseback. If you’ve paid for equipment within the last ninety days, we can help you recoup your investment and allow you to make low monthly payments. This also frees up money in your budget rather than tying it down to a fixed asset.
