How does a magnetic stirrer work?
A magnetic stirrer operates on a simple yet highly effective principle:
- A rotating magnet (driven by a motor located under the plate) generates a rotating magnetic field.
- A magnetic stir bar (or stirring bar) placed in the container follows this field and rotates the liquid.
This system allows for the homogenization of liquids in beakers, Erlenmeyer flasks, or sealed vials, while avoiding contamination or sample loss through direct mechanical contact.
The advantages of a magnetic stirrer in the laboratory
The magnetic stirrer offers numerous advantages:
-
No heavy maintenance: no mechanical parts in direct contact with the liquid.
-
Sterile stirring possible: the magnetic stir bar is autoclavable.
-
Suitable for small volumes: ideal for volumes from 50 ml to several liters.
-
Compactness: takes up little space on the laboratory bench.
-
Compatibility with hot plates: some models combine stirring and heating simultaneously.
Whether for chemical preparations, biological mixtures, or analytical tests, it represents an essential gain in time and precision.
Essential criteria for purchasing your magnetic stirrer
To choose your magnetic stirrer wisely, consider:
-
Maximum stirring volume: adapt the model to the volume of your usual samples.
-
Rotation speed: some models offer variable speeds from 100 to 1500 rpm to adjust the vortex strength.
-
Thermal stability: check for compatibility with hot plates if necessary.
-
Materials: stainless steel or ceramic plate for increased chemical resistance.
-
Precise control: digital display or manual controls depending on your need for precision.
It is also important to adapt the size of the magnetic stir bar to the diameter of the container for maximum stirring efficiency.
Why opt for a refurbished magnetic stirrer?
Investing in a refurbished magnetic stirrer has many benefits:
-
Reduced price: savings of 30 to 60% compared to buying new.
-
Checked equipment: each device is tested to ensure speed, stability, homogeneity, and heating (where applicable).
-
Professional warranty: peace of mind guaranteed.
-
Eco-friendly approach: limiting the production of new equipment.

Magnetic stirrer price: how much should you budget?
The price of a magnetic stirrer varies according to several criteria:
-
Stirring capacity: a model designed for 1 liter will be much cheaper than a model supporting 20 liters.
-
Heating function: a heating magnetic stirrer is on average 1.5 to 2 times more expensive than a model without heating.
-
Quality of materials: stainless steel, ceramic, and chemically resistant plates directly influence the price.
-
Precision and control: digital display, fine adjustment of speed and temperature increase the final cost.
As a guide:
- A basic magnetic stirrer starts around €100 for small volumes without heating.
- A high-performance heating model can cost between €400 and €1200 depending on the features.
- Specialized equipment for large volumes or very precise applications can exceed €2000.
By choosing a refurbished model from Rewake, you can obtain high-end stirrers for 40 to 60% of the new price, without compromising on quality.
