Magnetic stirrers are often used in chemistry and biology.
They are preferred over gear-driven motorized stirrers because they are quieter, more efficient, and have no moving external parts to break or wear out (other than the simple bar magnet itself).
Because of its small size, a stirring bar is more easily cleaned and sterilized than other stirring devices. They do not require lubricants which could contaminate the reaction vessel and the product. They can be used inside hermetically closed vessels or systems, without the need for complicated rotary seals.
Magnetic stirrers may also include a hot plate or some other means for heating the liquid.
A device that can be found in almost every laboratory and is used to mix liquids and solutions in a simple way, without the need for a stir bar.
How a magnetic stirrer works
The vessel with the liquid is placed on the magnetic stirrer, a magnet is thrown into the vessel a magnetic stirrer.Inside the stirrer there is a motor with a magnet that rotates theThe magnet inside the vessel without any contact between them.The larger the motor and the larger the magnet length and diameter the larger the amount of liquid can be mixed,A magnetic stirrer is not suitable for mixing high-viscosity liquids but only for aqueous liquids.
-Useful for small volumes up to 8 liters, there are models with extremely powerful engines up to 30 liters
