Why use a heating magnetic stirrer?
The heating magnetic stirrer is designed to meet two simultaneous needs in the laboratory:
- Maintain constant agitation of liquids to homogenize mixtures, ensure dissolution or avoid sedimentation.
- Precisely control the temperature with an adjustable heating plate, essential for many chemical or biological reactions.
Its use has become essential in various fields: analytical chemistry, molecular biology, pharmaceutical industries, cosmetology and even materials science.
How a Magnetic Heating Stirrer Works
Principle of magnetic stirring
A rotating magnet placed under the plate generates a magnetic field that drives a magnetic bar placed in the liquid. The bar rotates and stirs the contents of the container, without direct mechanical contact.
Integrated heating
The magnetic stirrer plate contains thermal resistors that ensure a rapid and even temperature rise. Most modern models incorporate precise electronic control, often via a thermostat or an external temperature sensor (Pt100 probe or thermocouple).
The advantages of a magnetic heating stirrer in the laboratory
Choosing a heating magnetic stirrer offers many benefits:
-
Space saving : two pieces of equipment combined into one.
- Energy saving through targeted control of heating and agitation.
- Reduced risk of contamination due to the absence of submerged mechanical parts other than the bar.
- Ease of use with simple controls (analog or digital).
- Wide compatibility with different types of containers: beakers, Erlenmeyer flasks, test tubes.
Criteria for choosing a heating magnetic stirrer
Before investing in a magnetic stirrer heater , consider:
- Mixing capacity (maximum volume in liters).
- The temperature range and accuracy of the thermostat.
- The display type (digital or analog).
- The material of the plate (stainless steel, ceramic, coated aluminum).
-
Adjustable stirring speed (in revolutions per minute - rpm).
- Compatibility with an external probe to measure the temperature of the liquid and not that of the plate.
The choice of model will depend heavily on your specific applications: delicate chemical synthesis, cell culture, dissolution of solids, etc.
Common Applications of Magnetic Stirrer Heater
The uses of the heating magnetic stirrer are numerous:
- Dissolution of chemical compounds requiring a constant temperature.
- Preparation of microbiological culture media .
- Agitation of colloidal suspensions in materials chemistry.
- Enzymatic reactions in molecular biology.
- Maintaining viscous substances in solution during heating.
Thanks to their versatility, they have become standard equipment in academic research as well as in the pharmaceutical and chemical industries.
Magnetic Stirrer Heating Price: What to Expect?
The price of a heating magnetic stirrer depends on several criteria:
- Mixing capacity : a model designed for 1 liter will be much cheaper than a model supporting 20 liters.
- Temperature range and accuracy : The more the equipment is capable of rapid and controlled increases, the higher its price.
- Materials used : A chemical-resistant ceramic plate costs more than a simple painted aluminum plate.
- The presence of an external probe : some stirrers offer direct control of the liquid temperature, which improves precision but increases the price.
On average, here are the price ranges observed:
- Basic heating magnetic stirrer: between €150 and €400.
- Professional model with digital display and external probe: between €600 and €1500.
- High-end devices for large volumes (>10 liters): over €2,000.
Best price for a heating magnetic stirrer: how to choose the right one?
If your goal is to get a magnetic stirrer heater at the best price , here are some practical tips:
- Identify your needs precisely: there is no point paying for superfluous features if your application remains simple (e.g.: stirring aqueous solutions at moderate temperature).
- Compare several brands and models: some brands offer excellent value for money without compromising on safety (e.g. Stuart, IKA, Velp Scientifica).
- Consider refurbished : A certified pre-owned model often provides access to a high level of performance at a reduced cost.
- Check the warranty: choose a reputable seller who offers at least a 6-month warranty on the device.
At Rewake, we select refurbished models from major brands, tested and guaranteed to ensure optimal performance at a lower cost.
Used magnetic heating stirrer: a smart alternative
Investing in a used magnetic stirrer heater is a great option for:
- Reduce your equipment budget while accessing professional models.
- Access advanced features normally unaffordable in new builds (temperature controlled by probe, variable speed, high resistance ceramic plates).
- Limit your environmental impact by extending the lifespan of equipment that is still fully operational.
However, be careful to check certain points before purchasing:
- Perfect operation of the agitator and heating system.
- Visual condition of the plate (absence of cracks or excessive wear).
- Possible presence of accessories (magnetic bar, temperature probe, manual).
- Availability of a minimum guarantee to secure your purchase.
On our site, you will find a selection of reliable equipment such as a laboratory vortex mixer suitable for all types of scientific and industrial applications.
