Understanding lab shaker uses helps control and predict research outcomes. Whether you want to mix, agitate, or aerate samples, there is a shaker for your research needs. 

We will examine different types of lab shakers in detail. We will also look at the criteria for choosing suitable shakers.

What Is a Laboratory Shaker?

A laboratory shaker is a very common tool in research centers. It is used for moving samples in a controlled environment to observe or achieve different outcomes.

How it works

A lab shaker is used to agitate or mix substances. It moves in a specific direction, such as in a circle or along a line. 

Purposes

This popular piece of lab equipment can achieve different purposes. You can use them to mix reagents, promote microbial growth, and enhance chemical reactions.

Applications

You will find lab shakers in most facilities. From pharmaceuticals to cosmetics to biology, they are the basic equipment.

Orbital Shakers

They are the most common type of shakers for general mixing. While they are not suitable for high-viscosity samples, they are an excellent choice for low-shear samples.

Motion

It works by moving the samples in a circular motion. It offers gentle, uniform mixing. You can adjust the speed and the orbit diameter accordingly.

Applications

Common usage includes cell culture, microbial growth, solubility studies, and general mixing. They are a cost-effective choice for laboratories.

Advantages

There is low shear stress. It is suitable for delicate samples. The consistent aeration offers stable, reproducible results.

Platform (Reciprocating) Shakers

A platform shaker is a more aggressive mixing tool that can handle vigorous mixing needs.

Motion

It moves back and forth in a linear motion, providing stronger agitation than orbital shakers. 

Applications

Since it can handle heavier and denser samples, a platform shaker is used for washing membranes and the extraction process.

Advantages

It can handle materials with higher viscosities. It is also suitable for large-batch mixing. However, it should be noted that a platform shaker should not be used for sensitive samples due to its vigorous motions.

Incubator Shakers

These are high-performing shakers with built-in environmental controls to create a stable setting.

Motion

It is usually an advanced version of an orbital shaker. It moves in circular motion with temperature control. You can precisely manage the temperature, humidity, and even CO2.

Applications

Incubator shakers are great for cell growth and protein expression thanks to their environmental-controlled features.

Advantages

It combines shaking and incubating, which is convenient and useful for advanced facilities. The upfront costs are higher, but it meets the needs for large-scale labs better.

Vortex Mixers

A vortex mixer is almost a standard piece of equipment in every lab, regardless of the size.

Motion

It produces a high-speed circular, eccentric motion. 

Applications

It is designed to handle small volumes for rapid mixing, homogenization, or suspension. Vortex shakers can also be used for sample preparation. 

Advantages

This mixer is fast and efficient. It saves time and is easy to operate.

Rocking Shakers (See-Saw Shakers)

Created for low-impact agitation with adjustable tilt angles and speeds for flexibility.

Motion

It goes in a gentle, seesaw-like tilting motion. Its low-speed, low-shear mixing makes it a great choice for delicate samples.

Applications

Researchers use rocking shakers for gel staining, cell culture, and hybridization.

Advantages

It produces minimal stress on the samples and prevents foaming, protecting sample integrity.

Magnetic Shakers (Stirrers with Shaking Function)

Magnetic shakers are slightly different. Some models offer optional heating features as well.

Motion

It combines magnetic stirring with optional shaking or heating using a magnetic stir bar inside the container.

Applications

Most labs use magnetic stirrers for mixing. From chemical reactions to dissolving solids, they are a versatile tool.

Advantages

It offers precise control without direct mechanical contact with the material. For low-viscosity samples, it produces stable results.

Microplate Shakers

Designed specifically for multi-well plates, such as 96-well and 384-well, microplate shakers are compact and high-throughput compatible. 

Motion

It works in orbital or linear motions, typically.

Applications

Microplate shakers are usually used for ELISA assays and drug screening.

Advantages

It provides uniform mixing across all wells and is ideal for an automated workflow.

Key Factors When Choosing a Lab Shaker

Choosing a lab shaker does not have to be complicated. Consult with a professional like IKA to make the best choice

Sample type

Do you work with high or low-viscosity samples? Do you need vigorous or gentle mixing? What is the container size you work with?

Budget

Set a budget for your next equipment purchase. From that, you can determine the right combination and optional features to get.

In conclusion

Every lab needs shakers. Getting the right one will boost efficiency and performance. Choosing a shaker depends on your needs and budget. You can discuss with experts to find out how different shakers can benefit your work.
