A magnetic stirrer or magnetic mixer is a laboratory device that employs a rotating magnetic field to cause a stir bar (or flea) immersed in a liquid to spin very quickly, thus stirring it. The rotating field may be created either by a rotating magnet or a set of stationary electromagnets, placed beneath the vessel with the liquid.
A laboratory hot plate with magnetic stirrer. Hotplates are used in laboratories, outside the domestic environment, mainly for heating, and possibly continuously stirring, liquids. [5] In laboratory settings, hot plates are generally used to heat glassware or its contents. Some hot plates provide an integrated magnetic stirrer, allowing a ...
A stirring rod is used for mixing liquids, or solids and liquids. Stir rods are used as part of proper laboratory technique when decanting supernatants because the contact helps to negate the adhesion between the side of the glassware and the supernatant that is responsible for the liquid running down the side. Using a stir rod also grants more ...
Paramagnetic Fe3O4 particles are extracted from a petroleum–based ferrofluid or synthesized in a laboratory and then suspended in water. When exposed to a strengthening magnetic field these particles organize into chains that diffract light and cause the solution to change color from a brown to red, yellow, green and then blue.
A temperature-controlled shaker, as used in biochemistry work. A shaker is a piece of laboratory equipment used to mix, blend, or agitate substances in a tube or flask by shaking them. It is mainly used in the fields of chemistry and biology. A shaker contains an oscillating board that is used to place the flasks, beakers, or test tubes.
An agitator is a device or mechanism to put something into motion by shaking or stirring.There are several types of agitation machines, including washing machine agitators (which rotate back and forth) and magnetic agitators (which contain a magnetic bar rotating in a magnetic field).
