The magnetic stirrer is easy to operate, has stepless speed adjustment, and can perform precise and stable stirring of liquid solutions in a wide speed range. It is especially suitable for testing small-volume samples. Magnetic stirrers can be divided into three categories: unheated, heated, and constant temperature. Some models have added two-way and multi-head stirring functions. It is a necessary and satisfactory tool for modern petroleum, chemical industry, medicine and health, environmental protection, biochemistry, experimental analysis, education and scientific research.
