Description
Technical Parameters
Small Magnetic Stirrer, it is a widely used small-scale stirring device in laboratories. It drives the stirrer to rotate in the container through magnetic force, achieving various functions such as mixing the solution, uniformly suspending particles, and heating reactions. As an important laboratory and industrial equipment, it plays an irreplaceable role in multiple fields such as chemistry, biology, and medicine. With the continuous advancement of technology and the increasing demand for experiments, it will continue to develop towards intelligence, multifunctionality, modularity, high efficiency and energy saving, ease of use and humanization, as well as big data analysis and cloud computing.
Operation precautions
When using a small magnetic stirrer, the following matters need to be noted to ensure safety and effect:
Select the right magnetic stirrer for the application.
When using for the first time, check whether the instrument is complete by referring to the instrument instructions, such as stirrer, power cord, etc.
It is best to ground the instrument well when using it.
When placing the solution in the container, do not overfill it, and leave enough space to avoid the solution spilling out and corroding the body during the mixing process.
Speed regulation should be gradually adjusted from low speed to high speed, it is best not to start directly from high speed, so as not to cause the mixer to beat out of synchronization.
If the magnetic stirrer is equipped with a heating function, it cannot be heated without stirring, and the continuous heating temperature shall not exceed 2 hours when the temperature exceeds 70 ° C (for some models).
The instrument should be kept clean and dry, and the mixer should be cleaned after use, and the disk surface should be wiped with a clean cloth.
Characteristics of magnetic coupling effect
Contactless transmission of power
As a specific application form of magnetic coupling, magnetic couplers achieve contactless transmission of power through magnetic fields. This transmission method avoids problems such as friction, wear, and leakage in traditional mechanical transmissions, improving the reliability and service life of the system. Meanwhile, due to the non-contact transmission of power, magnetic couplers can also operate stably in harsh working environments such as high temperature, high pressure, corrosion, etc.
Wide adjustment range
Magnetic couplers can adjust the speed and torque of loads within a wide range, achieving stepless speed regulation. This characteristic gives magnetic couplers significant advantages in situations where precise control of speed and torque is required. By adjusting the current of the driving magnet or changing the distance between the magnets, it is easy to adjust the output torque and speed to meet different working requirements.
Energy saving and environmental protection:
Due to the non-contact transmission of power by the magnetic coupler, energy loss and heat emission caused by friction and wear are reduced. Meanwhile, by precisely controlling the load speed and reducing pipeline losses, the system efficiency can be further improved and energy consumption can be reduced. In addition, magnetic couplers also have good sealing performance, which can effectively prevent medium leakage and environmental pollution problems.
Strong adaptability:
Magnetic couplers are suitable for various harsh working environments, including flammable, explosive, humid, high dust content, high temperature and low temperature places. This wide adaptability enables magnetic couplers to be widely used in multiple industries. Whether it is the reaction kettle and storage tank transmission system in the chemical industry, or the leak free mixing equipment in the pharmaceutical industry; Whether it is the transmission system of rotating equipment in the film and electroplating industry, or the transmission system of high-pressure vessels and nuclear reactors in the nuclear power industry; Small Magnetic Stirrer couplers can all exert their unique advantages and functions.
