A laboratory magnetic stirrer is a vital piece of laboratory equipment whose function is to mix liquids rapidly and effectively. This type of device is commonly found in pharmaceutical labs, chemical industries, biotechnology research labs, academic facilities, and quality control laboratories where there is a need for proper mixing of solutions free from human input. A laboratory magnetic stirrer is more advanced than traditional stirring devices, because the device mixes liquids through rotation of a magnetically controlled stir bar.
Many laboratories opt for the use of a magnetic stirrer hot plate where both heating and stirring of liquids can take place simultaneously from a single compact source of laboratory equipment. The combination serves well in saving space and improving efficiency.
Bionics Consortium produces and distributes high-quality laboratory equipment for use in various laboratories. We produce our own magnetic stirrers that are suitable for precise mixing of liquids during preparation of solutions and other laboratory processes.
With emphasis on quality, innovation, and customer satisfaction, Bionics Consortium provides laboratory equipment that ensures professionals receive precise and reliable results from their laboratory work.
A magnetic stirrer is an electronically powered laboratory equipment used to agitate solutions by means of a rotating magnetic field. This equipment contains a magnetic stir bar that is made from PTFE and placed inside the solution to be stirred and a magnet placed at the base of the equipment and rotated.
In contrast to mechanical stirrers, the magnetic stirrers do not contain any rotating parts that may touch the solution hence there is minimum risk of contamination and makes them ideal for use in laboratory setups.
For temperature-sensitive laboratory experiments, the combination of the magnetic stirrer and hot plate will serve both purposes of heating and agitation.
The magnetic stirrer works according to the principle of magnetic coupling where there is a magnet present inside the device. The magnet rotates to create a magnetic field which causes the rotation of the stir bar that is placed inside the container.
This method of mixing is without any physical contact and it makes the process much safer and easy to maintain with consistent results. Therefore, the use of magnetic stirrers has become one of the most trusted devices used in scientific laboratories.
However, in addition to that, it is essential to adhere to safety rules in laboratory practice. Additional information regarding laboratory safety can be found at Laboratory Safety of the Occupational Safety and Health Administration.
The rotating magnetic field turns the stir bar and generates a vortex. A magnetic stirrer is composed of the following parts: stirring base, magnetic drive system, speed control knob, heating base, power switch and magnetic stir bar.
There are different types of magnetic stirrers that are used in different experimental setups depending on their suitability.
The standard magnetic stirrer is useful for mixing liquid without the need for heat. This is commonly found in educational institutions such as schools, colleges, research laboratories, and quality control processes.
This is a combination of magnetic stirrer and hot plate; this is effective in synthesis of chemicals, mixing solutions, and pharmaceuticals research.
This is useful for efficient mixing of low viscosity to medium viscosity liquid.
For simultaneous stirring of more than one sample at a time.
The magnetic stirrer comes with some benefits that include:
Good for conducting experiments in the laboratory on a regular basis.
Flexibility of operation offered by the magnetic stirrer makes it an invaluable equipment for many industrial sectors.
Laboratory magnetic stirrer is employed extensively in the production of drugs, preparation of buffer solutions, dissolution tests, and quality assurance.
Reagents' preparation, mixing of solutions, chemical reactions, and titration are some common uses of magnetic stirrer in a chemical laboratory. A heated magnetic stirrer is particularly handy when a reaction requires heating along with continuous mixing.
In biotech and microbiology labs, researchers use the magnetic stirrer to prepare culture media, enzyme solutions, biological buffer solutions, and microbial samples without any risk of contamination.
In environmental and food laboratories, a magnetic stirrer plays its role in the preparation of water, wastewater, soil, and food samples before conducting laboratory tests on them.
In selecting an appropriate magnetic stirrer for laboratory use, one needs to have a particular consideration for what his or her laboratory needs. Some of the things that ought to be considered before making purchases include stirring capacity, range of speeds, heating function, temperature controls, among others. A good magnetic stirrer must offer accurate speed controls and efficient performances as well as durability of its surface against chemicals.
The magnetic stirrer price is determined by its specifications while the magnetic stirrer with hot plate price is relatively high because of the heating component.
The specifications of a magnetic stirrer may vary depending on the model and laboratory application. The table below provides a general overview of the key features to consider before purchasing.

The magnetic stirrer is a scientific instrument which uses the magnetic field to rotate and stir the liquid using the magnetic stir bar.
It functions on the basis of magnetic coupling where the rotating magnetic field rotates the stir bar.
Its uses include preparing solutions, mixing chemicals, pharmaceutical research, microbiology, and laboratory testing.
The magnetic stirrer can only stir the solution while the magnetic stirrer hot plate both stirs and heats the solution.
Yes, the magnetic stirrer for laboratory purposes is perfect for research and quality control testing.
These are widely used in pharmaceuticals, chemical, biotech, food, environmental and educational laboratories.
Cost depends on its stirring ability, heating capability, range of speed and temperature control and build quality.
The magnetic stirrer is suitable for stirring low to medium viscosity liquids. Thick solutions may need a mechanical stirrer.
Proper cleaning, usage of the right stir bar, no overloading and regular inspection of electrical parts are recommended.
