The magnetic stirrer is easy to operate and has stepless speed regulation. It can precisely and stably stir the liquid solution in a wide speed range, and is especially suitable for the test of small volume samples. Magnetic stirrers can be divided into three types: non-heating type, heating type, and constant temperature type. Some models have added two-way and multi-head stirring functions. It is a desirable tool for modern petroleum, chemical industry, medicine and health, environmental protection, biochemistry, experimental analysis, education and scientific research.
HJ-2A digital display double-head constant temperature magnetic stirrer is widely used in various colleges and universities, environmental protection, scientific research, health, epidemic prevention, petroleum, metallurgy, chemical, medical and other equipment. This instrument has good performance and no noise.
