ANGNI AM200W-O Laboratory Electric Stirrer 30L/2000rpm

The electronic constant speed mixer is driven by a brushless DC motor and is suitable for stirring and mixing low to medium and high viscosity liquids in the laboratory. The machine has a reasonable and compact structure, ultra-low noise, and maintenance-free. The stirring speed is controlled by a microprocessor, which can promptly and effectively compensate the speed change caused by load changes and power supply Voltage fluctuations, and the constant speed is reliable. The built-in automatic overload protection device ensures the safety of the long-term high-load continuous operation of the experiment; the operating status knob control makes the experimental operation easier, and the stirring speed can be adjusted steplessly to meet the correction of the stirring speed during the experiment; the digital display setting and actual output The stirring speed ensures the intuitive collection of experimental data; the operation Timer Control ensures that the timeliness of the experiment is effective and controllable. Stable stirring speed, capable of stirring high-viscosity media and slurry.

Experimental principle

Stirring and mixing are two of the oldest fundamental human behaviors, with origins dating back to early food preparation. When making soup, you need a spoon to stir in the jar. The process of the spoon acts as the mixing tool, and the hand in a circular motion acts as the mixing drive. Even such a primitive mixing process requires practical experience in order to achieve the desired effect.

Mixing is the process of combining several materials of different origin under the action of external energy. Due to the different aggregation states, compositions, chemical and physical properties of the substances, it is difficult to estimate the form of the mixture. Parameters such as density or density and viscosity of powdered substances are of great importance when performing a mixing process. These parameters determine the energy requirements, possible compatibility, degree of dispersion, and stability of the mixture.

Stirring can be applied to the homogenization of compatible liquids, as well as the dissolution and mixing of solid particles in liquids. Adjusting the balance for differences in temperature or concentration will make the stirring process more efficient. In addition, increasing the liquid stirring speed can speed up the dissolution process and will increase the speed of the chemical reaction. Stirring is widely used in schools and universities as well as biotechnology, chemical, pharmaceutical, food and other industries. Wherever there is chemical product production and processing, there will be mixing.

When the movement or low shear needs of the liquid can be achieved by the specific application, good agitation becomes a convenient mixing process.
