Laboratory stirrers play a crucial role in mixing and agitating samples before analysis. Since it is not always easy to choose the right equipment in front of a multitude of manufacturers, we have produced this buying guide with tips and recommendations to help you make the right purchasing decision.

Laboratory Stirrer: A Comprehensive Guide

There are various types of laboratory stirrers, each catering to different needs.

1/ Magnetic Stirrers

Magnetic stirrers are the most common laboratory stirrers. The base houses an electric motor and a plate. This is where the solution container is positioned. An electric motor then rotates a magnetic bar inside the container, effectively stirring the sample.

2/ Overhead Stirrers

Overhead stirrers are designed for stirring, mixing, and homogenizing liquids, especially those with high viscosity. Unlike magnetic stirrers, they are placed on top of the container.

3/ Vortex Stirrers

Vortex stirrers are commonly used in molecular biology. They allow rapid mixing of solutions directly within test tubes or microtubes. These devices feature a sturdy base topped with a rubber receptacle. When the operator presses down on the receptacle using the bottom of a test tube, the electric motor activates, creating a low-amplitude, high-speed orbital motion within the test tube and its contents.
