1. Product introduction
Magnetic stirrers are laboratory instruments for liquid mixing, mainly for stirring or simultaneously heating and stirring low-viscosity liquid or solid-liquid mixtures. The basic principle is to use the magnetic field of the same-sex repulsion and opposite-sex attraction principle, and use the magnetic field to push the magnetic stirrer placed in the container to rotate in a circle, so as to achieve the purpose of stirring the liquid. With the heating temperature control system, the sample temperature can be heated and controlled according to the specific experimental requirements, maintaining the temperature conditions required by the experimental conditions, and ensuring that the liquid mixing meets the experimental needs.
1. Product principle
Magnetic stirrer, English name Magnetic Stirrers, is an instrument that uses magnetic force to stir the liquid to make it uniform. It has two effects on the liquid, one is the stirring effect, the magnetic field generated by the base drives the stirring rod to make a circular circular motion to make the liquid mix evenly, and the other is the heating effect, and the high temperature is more conducive to the uniformity of the liquid. Magnetic stirrers are highly efficient and portable, and are now widely used.
The magnetic stirrer uses the principle that magnetic substances of the same sex repel each other in the magnetic field. The change of the polarity at both ends of the base drives the stirrer to make a circular motion, so that the liquid rotates and gradually reaches uniformity; the base also contains a temperature control board, It is used to heat the liquid, which is more conducive to the mixing of the liquid; in some magnetic stirrers, it also contains a heating power adjustment part, which is used to control the temperature. It is often used to accurately control the temperature during the experiment to reduce Small number of replicates.
2. Product use
The heating magnetic stirrer adopts DC motor, which has low noise and stable speed regulation. The fully enclosed heating plate can be used for auxiliary heating. The constant temperature magnetic stirrer can set the temperature and temperature display, can be used for long-term heating, and the digital display is intuitive and accurate. The stirrer is made of PTFE and magnetic steel, which is resistant to high temperature, wear, chemical corrosion and strong magnetic properties. It can be mixed in a closed container, which is ideal and convenient to use.
3. Product description
Magnetic stirrers are mainly used for dissolving, heating and batching in food and other industries. What role does it play in this, and what are the advantages compared with ordinary mixers? Now I will introduce it to you.
The first function of stirring is to mix the reactants evenly and make the temperature uniform; the second is to heat in a closed container, which needs to prevent bumping. For example, in the process of distillation, zeolite can be added, or Use a magnetic stirrer; the third function is to speed up the reaction, or evaporation, and shorten the time.
