An Overview of Magnetic Stirrers

If you are new to the world of magnet stirring or are still trying to figure out how best to use this equipment, this article explains what these instruments entail. Below, we discuss the uses of magnetic stirrers and some of the benefits they offer. 

What Is a Magnetic Stirrer

A magnetic stirrer is an equipment with a plate containing a rotating magnet and a small bar magnet used to create a rotating magnetic field. This bar magnet is coated with plastic, allowing the plate with the rotating magnet to create the rotating field. When a magnetic field is applied to the stirrer during operation, this enables you to mix solutions as needed. This is facilitated by the rotation of the small magnetic bar which is placed in your desired mixture. 

Uses of a Magnetic Stirrer

The magnetic stirrer helps mix components such as liquids and solids, allowing you to get a homogenous liquid mixture. Most of these experiments are biology and chemistry-based, with some examples of commonly used samples being bacterial growth media or solutions that need buffering. 

Generally, magnetic stirrers come in handy when you need to agitate liquids, improve mixtures, or need help speeding up reactions. 

Advantages of Using Magnetic Stirrers

Minimizes Contamination

If you need to carry out lengthy procedures on one sample, magnetic stirrers reduce any risk of contamination. Since you only require one magnetic bar for your experiments, your need for utilizing other instruments is lowered, helping you keep your samples free from contaminants.

They Are Easy To Clean

Unlike other stirrers that will often involve multiple devices, magnetic stirring eliminates the need for extra equipment, making your clean-up easy. This allows you also to undertake more work with half your usual number of devices.

If you are looking for dual-purpose equipment that offers you heating and stirring functions, a magnetic stirrer is what you need. It will especially be helpful if you are looking to reduce your maintenance costs while offering you high-quality performance.
