Technical Parameters
DIY hot plate magnetic stirrer is a device that can be made by oneself and used for stirring liquids. It mainly consists of heating plate, electromagnetic stirer, temperature control system, and outer shell. Heat the liquid in the container through a heating plate and stir it with a stirrer to achieve uniform heating and mixing of the liquid. It is a simple and self-made experimental equipment, mainly used for stirring liquids in chemical, biological and other experiments.
DIY heating magntic stirer is a highly practical and innovative self-made experimental equipment designed to meet the liquid stirring needs in fields such as chemistry and biology. Its core components include a heating plate, an electromagnetic stirrer, a temperature control system, and a housing, which work together to achieve uniform heating and efficient stirring of the liquid.
Heating plate, a source of thermal energy, typically uses efficient and durable electric heating elements such as heating wires or electric heating films to ensure fast and stable heating of liquids in containers. Through a precise temperature control system, users can easily set and adjust the required heating temperature to meet the specific requirements of the experiment.
Electromagnetic stirrr, responsible for stirring liquids. It utilizes the principle of electromagnetic induction to generate a magnetic field through internal electromagnetic coils, attracting and driving the magetic stirer at the bottom of the container to rotate. This non-contact mixing method not only avoids the pollution problems that traditional mixers may cause, but also greatly improves mixing efficiency and uniformity.
The shell, as a protective layer, not only plays a role in aesthetics and fixation, but also has certain insulation and anti electric shock functions. It is usually made of materials that are resistant to high temperatures and corrosion, ensuring that the equipment can maintain good performance and safety during long-term use.
The principle of DIY hot plate magnetic stirrer
Our latest projects
The instrument mainly utilizes force to adsorb it onto the hot plate and continuously stir the liquid with the rotation of the hot plate. The principle can be divided into the following parts:
Magnetic adsorption:
It contains magnets inside, and when it approaches the hot plate, force will firmly attach the machine to the hot plate. The effect of it adsorption enables to rotate synchronously with the rotation of the hot plate, thereby achieving stirring of the liquid.
Hot plate heating:
The hot plate is an important component of the DIY hot plate it, which is heated by an electric heating element to maintain a certain heat on the surface of the hot plate. It can be used to heat liquids to reach the desired reaction temperature.
Liquid stirring:
When the hot plate rotates, it adsorbed on the hot plate will also rotate, thereby driving the surrounding liquid to rotate and stir. This stirring method can accelerate the progress of chemical reactions and improve experimental efficiency.

It has a simple structure, convenient operation, and high stability. Therefore, cleaning and maintenance are much more convenient than traditional mechanical mixers.
Automatic stirring:
The automatic stirring function is a major highlight of DIY hot plate, which enables the entire stirring process to be carried out without direct human intervention, greatly improving the accuracy and safety of experiments.
In the process of chemical experiments, manual stirring often requires continuous operation by researchers, which not only increases the complexity of experimental operations, but also easily leads to misoperation due to human factors, such as uneven stirring speed, insufficient or too long stirring time, etc., which may have adverse effects on experimental results. The automatic stirring function of the DIY hot plate can accurately control the stirring speed and time, ensuring that each experiment can be conducted under the same conditions, thereby improving the repeatability and accuracy of the experiment.
Safe and reliable:
Due to its use of a DIY Hot Plate Magnetic Stirrer drive mechanism, there are no safety hazards directly caused by physical factors such as mechanical vibration and electrostatic pressure during operation. Magnetic stirring technology uses non-contact methods to drive the stirrer to rotate by the force of a magnetic field, thereby avoiding the noise, wear, and potential failure risks that traditional mechanical stirrers may experience due to friction and vibration.
In addition, electrical safety is usually emphasized in the design process, including the use of insulation materials, the installation of overheating protection devices, and ensuring the safe connection of power lines to prevent electrical safety hazards such as short circuits and leakage. Meanwhile, the heating plate is usually made of materials that are resistant to high temperatures and corrosion, ensuring that there will be no safety hazards such as deformation or melting during long-term high-temperature heating.
