The hotplate stirrer (or hot plate stirrer or hot plate magnetic stirrer) is used for mixing and heating aqueous solutions for a great variety of chemical reactions such as synthesis. VELP hotplate stirrers are available in various models and combinations in both analog and digital configurations.
Likewise, people ask, how do magnetic hot plates work?
This vessel, usually made of glass, is placed on the stirring unit’s platform. Underneath the platform, a rotating magnetic field is created by either a rotating magnet or by running electric current through stationary electromagnets.
Simply so, how does a stirrer work?
Magnetic stirrers use a rotating magnetic field to move a stir bar around in liquid samples. The movement of this stir bar mixes the sample thoroughly with rapid movement and agitation. The speed of the magnetic field is controlled by the user, so it can be customized to the specific sample that’s being stirred.
Is magnetic stirrer hot?
A standard piece of laboratory equipment, the hot plate stirrer / hot plate magnetic stirrer keeps liquids circulating as they are heated for a faster, more even reaction.
What are the two types of stirrer?

What does stirrer mean?
What is a laboratory hot plate?
Hot plates are frequently used in the laboratory to perform chemical reactions, to heat samples, and for numerous other activities. Hot plates are conceptually simple – a flat surface with heating elements. They do not produce open flames and are well suited for oil or sand bath use.
What is a stirrer made of?
Stir rods are generally made of borosilicate (commonly known as Pyrex) glass or polypropylene plastic. They are usually between 10 and 40 centimeters in length and about half a centimeter in diameter. Glass rods are created from a single length of thin glass that is then cut into smaller segments.
What is a Teflon stir bar?
Scientists have discovered that stir bars made of PTFE, more commonly known as Teflon, can introduce errors into a standard lab reaction used to manipulate the properties of carbon or boron-nitride nanotubes. Stir bars are pellet-like rods of ferromagnetic metal covered in PTFE that sit in the bottom of a beaker.
What is hot plate or stir plate?
A hot plate stirrer or a hot plate magnetic stirrer is a laboratory instrument that is typically used to stir and heat the solution simultaneously. This helps the person performing the experiment speed up the reaction and properly dissolve the solute in the solvent.
