Why use a laboratory stirrer?
The laboratory stirrer allows you to create controlled movement in liquids or viscous mixtures. This agitation is essential for:
- Homogenize chemical or biological solutions.
- Facilitate chemical reactions requiring optimal contact between reactants.
- Maintaining particles in constant suspension.
- Avoid precipitation or phase separation.
By adjusting the rotation speed, temperature (with a heated stirrer) or type of movement (magnetic, orbital, mechanical), process optimization is possible depending on the viscosity of the liquids handled.
The different types of laboratory stirrers
Magnetic stirrer
Using a magnetic field to drive a rotating bar at the bottom of the container, the magnetic stirrer is ideal for moderate volumes of low-viscosity liquids. Compact and quiet, it is ideal for small chemistry or molecular biology experiments.
Mechanical agitator
For denser mixtures or larger volumes, a mechanical stirrer equipped with a rod and propeller provides more powerful agitation. It is often used in the pharmaceutical, food, and chemical industries.
Heating stirrer
Combining heating and stirring, this device allows for maintaining a constant temperature while mixing. It is widely used in chemical syntheses requiring thermal activation.
Choosing the right used laboratory stirrer
Before investing in a new laboratory shaker, here are the key points to evaluate:
- Sample volume to be mixed: from a few milliliters to several liters.
- Viscosity of the liquid : requiring a more or less high engine torque.
- Type of agitation : magnetic for light fluids, mechanical for viscous fluids.
- Rotation speed : variable to adjust the mixing dynamics.
- Plate or rod material : stainless steel, ceramic, Teflon for chemical resistance.
- Ergonomics and control : digital display, cruise control, timer, etc.
A well-chosen stirrer improves the reproducibility of your experiments and reduces the risk of errors due to poor mixing.
Used Magnetic Stirrers: A Smart Choice for Your Lab
Purchasing a used laboratory stirrer is an excellent solution for combining performance and budget. At Rewake, we select magnetic stirrers from leading brands like IKA, Heidolph, and Velp, rigorously tested before being put back on sale.
The advantages of a reconditioned magnetic stirrer are numerous:
- Substantial savings : up to 50% off new.
- Guaranteed performance : each model is checked to ensure rotation speed, movement consistency and temperature precision.
- Eco-responsibility : extending the lifespan of equipment reduces the environmental footprint.
A used magnetic stirrer is therefore a smart alternative to efficiently equip your laboratory without compromising on quality.
Laboratory stirrer price: what budget should you plan for?
The price of a laboratory stirrer depends on several factors:
- Stirrer type : magnetic, mechanical, heating or orbital.
- Stirring capacity : small model for 500 ml or powerful stirrer for 10 liters and more.
- Options : temperature control, digital display, cycle programming.
- Brand : Some well-known brands like IKA or VWR offer high-end equipment that is more expensive but very robust.
For information:
- A simple magnetic stirrer: between €250 and €800.
- A heating stirrer: from €500 to €1500 depending on precision and capacity.
- An industrial mechanical agitator: from €1,000 to several thousand euros.
At Rewake, we offer refurbished equipment at ultra-competitive prices, without sacrificing technical performance or reliability.
Leboncoin fr laboratory stirrer: watch out for traps
If you're considering searching for a laboratory stirrer on Leboncoin.fr or other general sites, be extremely careful. Unlike specialists like Rewake, these platforms do not offer:
- 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 can exhibit invisible defects such as a loss of rotational speed precision, poor thermal uniformity, or a degraded motor. For demanding applications in biology, chemistry, or quality control, it's better to invest in validated equipment rather than take unnecessary risks.
