MAGNETIC STIRRERS

MAKE DINESH SCIENTIFIC

DESCRIPTION:

A magnetic stirrer is a type of lab instrument that generates a magnetic field that rotates, causing a stir bar, sometimes called a flea, to spin and mix the liquid it is submerged in. This device is frequently used in biology and chemical labs for a variety of tasks, such as homogenizing liquid samples, dissolving solutes, and mixing solutions.

THE MAIN PARTS OF A MAGNETIC STIRRER ARE DESCRIBED AS FOLLOWS IN GENERAL:

MOTOR:

• The rotational force required to rotate the magnetic stir bar is produced by the motor.
• Typically, a low-speed electric motor is used to guarantee a steady and regulated stirring action.

PANEL OF CONTROL:

• Magnetic stirrers frequently have a control panel that lets the user change how quickly the stirring occurs.
• Additional features like temperature control or programmed settings might be included in some advanced versions.

ACTIVATING SURFACE:

• A flat or curved surface on top of the base unit is usually available for placing containers or vessels.
• This is where the magnetic stir bar is immersed in the liquid stirred.

GENERATOR OF MAGNETIC FIELD:

• A magnetic field generator sits beneath the stirring platform. A magnetic field is often produced by a revolving magnet or set of magnets.
• The magnetic stir bar interacts with the magnetic field that penetrates the bottom of the container.

STIR BAR:

• Often called a flea or stir rod, the stir bar is a small, oval- or cylindrical-shaped piece of magnetic material (such PTFE or PTFE coated).
• The stir bar spins when submerged in a liquid on the stirring platform, swirling the liquid as a result of the magnetic field.
