Function: 1. Efficient and stable: The magnetic mixer adopts 5W high power brushless motor, which runs smoothly and efficiently, has a compact and strong structure, and has a long service life. 2. No noise: The middle position of the strongest magnetic force is marked on the panel, which helps to fix the mixing rod and prevents it from shaking, no noise and quiet operation at night. 3. Compact: small magnetic stirrer, saves work space, easy to store, large capacity, maximum mixing volume of 1L, can be used for containers of different sizes, lightweight and portable. 4. Universal: widely used in scientific research, industry, agriculture, health, medicine, etc., and can also be used for homemade beer such as beer yeast, brewing, sos, etc. 5. Liquid mixing: The magnetic mixer is mainly suitable for mixing liquids, mainly for mixing low viscosity liquids or solid liquid mixtures, not suitable for high viscosity solutions.
