Product Description
The heating magnetic stirrer combines the principle of the magnetic stirrer with the heating technology to generate a magnetic field in the bottom container by rotating the magnetometer, so that the magnetic stirrer in the container will rotate accordingly to achieve the stirring of the solution. At the same time, the container is heated by a heating element (such as an electric heating rod or electromagnetic induction heating), thus achieving the heating process of the solution.

A magnetic stirrer with heat is a fundamental piece of laboratory equipment designed to simultaneously mix and heat liquid samples. By utilizing a rotating magnetic field generated beneath a heated plate, the device drives a Teflon-coated or glass-coated stirring bar placed inside the vessel. This mechanism ensures efficient homogenization without the need for mechanical shafts that could contaminate the sample or introduce vibration. The integrated heating element allows users to precisely control temperature, typically ranging from ambient levels up to 350°C, depending on the specific model. This functionality makes it indispensable for applications such as dissolving solids, accelerating chemical reactions, maintaining constant temperatures during titrations, and preparing culture media in microbiology.
When operating this equipment, several critical safety precautions must be observed to ensure user protection and equipment longevity. First, always verify that the stirring speed is appropriate for the viscosity of the liquid; excessive speed can cause the stirring bar to jump out of the solution or damage the vessel. Second, never operate the heater if the hotplate surface is empty or if no container is present, as this can lead to overheating and permanent damage to the heating element. It is also vital to use heat-resistant glassware, such as borosilicate, to prevent thermal shock and breakage. Additionally, avoid placing flammable solvents directly on the hotplate unless the unit is specifically rated for such use, as open flames or high surface temperatures can ignite vapors. Always allow the unit to cool completely before cleaning or moving it to prevent burns. Regular maintenance, including checking the integrity of the stirring bar coating and ensuring the cooling fan vents are unobstructed, is essential for optimal performance. Properly used, a magnetic stirrer with heat serves as a versatile, reliable tool that significantly enhances efficiency and reproducibility in scientific research and industrial processes.
