Why use a laboratory stirrer?
A laboratory stirrer is used to create a controlled movement in liquids or viscous mixtures. This agitation is essential for:
- Homogenizing chemical or biological solutions.
- Facilitating chemical reactions that require optimal contact between reagents.
- Maintaining particles in constant suspension.
- Avoiding precipitation or phase separation.
By adjusting the rotation speed, temperature (with a heating stirrer), or type of movement (magnetic, orbital, mechanical), process optimization is possible depending on the viscosity of the liquids being handled.
The different types of laboratory stirrers
Magnetic stirrer
Using a magnetic field to drive a stir bar rotating at the bottom of the container, the magnetic stirrer is perfect for moderate volumes of low-viscosity liquids. Compact and quiet, it is ideal for small experiments in chemistry or molecular biology.
Mechanical stirrer
For denser mixtures or larger volumes, a mechanical stirrer equipped with a rod and impeller provides more powerful agitation. It is often used in the pharmaceutical, food, or chemical industries.
Heating stirrer
Combining heating and agitation, this device allows for a constant temperature to be maintained while mixing. It is widely used in chemical syntheses requiring thermal activation.
How to choose your pre-owned laboratory stirrer
Before investing in a new laboratory stirrer, here are the key points to evaluate:
-
Sample volume to be mixed: from a few milliliters to several liters.
-
Liquid viscosity: requiring a higher or lower motor torque.
-
Type of agitation: magnetic for light fluids, mechanical for viscous fluids.
-
Rotation speed: variable to adjust the dynamics of the mixture.
-
Plate or rod material: stainless steel, ceramic, Teflon for chemical resistance.
-
Ergonomics and control: digital display, speed regulator, timer, etc.
A well-chosen stirrer improves the reproducibility of your experiments and reduces the risk of errors associated with poor mixing.
Pre-owned magnetic stirrers: a smart choice for your laboratory
Acquiring a pre-owned laboratory stirrer is an excellent solution to combine performance with a controlled budget. At Rewake, we select magnetic stirrers from major brands like IKA, Heidolph, or Velp, which are rigorously tested before being resold.
The advantages of a refurbished magnetic stirrer are numerous:
-
Substantial savings: up to 50% discount compared to buying new.
-
Guaranteed performance: each model is verified to ensure rotation speed, uniformity of movement, and temperature accuracy.
-
Eco-responsibility: extending the lifespan of equipment reduces the environmental footprint.
A pre-owned magnetic stirrer is therefore an intelligent alternative for effectively equipping your laboratory without compromising on quality.
Laboratory stirrer price: what budget to plan for?
The price of a laboratory stirrer depends on several factors:
-
Type of stirrer: magnetic, mechanical, heating, or orbital.
-
Agitation capacity: small model for 500 ml or a powerful stirrer for 10 liters and more.
-
Options: temperature regulation, digital display, cycle programming.
-
Brand: certain recognized brands like IKA or VWR offer high-end equipment that is more expensive but very robust.
As a guide:
- A simple magnetic stirrer: between €250 and €800.
- A heating stirrer: from €500 to €1500 depending on precision and capacity.
- An industrial mechanical stirrer: from €1000, up to several thousand euros.
At Rewake, we offer refurbished equipment at highly competitive rates, without sacrificing technical performance or reliability.
Laboratory stirrer on Leboncoin.fr: beware of the traps
If you are considering looking for a laboratory stirrer on Leboncoin.fr or other general-purpose sites, be extremely cautious. Unlike specialists like Rewake, these platforms offer neither:
-
Serious technical inspection of the device.
-
Professional warranty covering breakdowns and hidden defects.
-
After-sales support for advice, installation, or maintenance.
A poorly maintained stirrer may have invisible defects such as a loss of precision in rotation speed, poor thermal uniformity, or a degraded motor. For demanding applications in biology, chemistry, or quality control, it is better to invest in validated equipment rather than taking unnecessary risks.
