A magnetic stirrer or magnetic mixer is a laboratory device that employs a rotating magnetic field to cause a stir bar also called flea immersed in a liquid to spin very quickly thus stirring itThe rotating field may be created either by a rotating magnet or a set of stationary electromagnets placed beneath the vessel with the liquid.

As illustrated by the above example viscosity can creep up without noticeSome reactions turn to thick slurries or form heavy precipitates as they progressSimilarly syrup preparations begin as pure water and end as sludgelike products particularly on cooling.

Aug 31 2021nbsp018332The magnetic stirrer is a stand containing a rotating magnet and a tiny bar magnetThe small bar magnet is typically covered in plastic and the stand has a rotating magnetTherefore this entire setup helps in creating a rotating magnetic fieldThe magnetic stirrer is used in various applications in different industries.

Aug 31 2021nbsp018332The magnetic stirrer is the only object that is immersed in the lab solutionThus human hands will not get into contact with the fluidsAlso it is easy to clean the stirrer and get rid of any contaminationThe benefits of using magnetic stirrers are immenseThey are durable efficient and help avoid contamination.

Because of its small size a stirring bar is more easily cleaned and sterilized than other stirring devicesThey do not require lubricants which could contaminate the reaction vessel and the productMagnetic stirrers may also include a hot plate or some other means for heating the liquid.

CAT Scientific Paso Robles CA provides further examples for putting aside your magnetic stirrer and setting up an overhead mixing system mixtures of water and organic solvents or of soluble and insoluble materials suspensions slurries pastes creams and polymer processes that show a wide range of viscosities.

Feb 25 2021nbsp018332Uses of Magnetic StirrersThe primary use of magnetic stirrer or hot plate with magnetic stirrer is to conduct biological and chemical experiments by mixing two componentsIt is equally suitable for solids or liquid samples to obtain a consistent liquid mixtureExamples include media for bacterial growth and chemical synthesis.

High heat output of 600 watts and white ceramic heating plate ensures rapid heating and a very good chemical resistanceAdjustable safety temperature from 100 to 360 176CSoftstart of the stirring motorIncludes M 10 thread for a support rodStrong magnetic field and wide speed range for volumes up to 15 liters.

Jun 15 2021nbsp018332A magnetic stirrer is an electric motor that stirs a mixture by rotating a stir bar placed in the mixture with the aid of an external magnetic fieldThe stir bar revolves at various speedsThe risk of contamination is reduced because the sample only requires a short magnet bar that can be readily washed and sanitized.

Nov 20 2018nbsp018332These stirrers should be used with glass or other nonmetal beakers to prevent interference with the magnetic fieldDepending on the application you can configure your magnetic stirrer with hot plates to heat your samples as they’re stirredWith the use of heating plates you can mix a wide variety of samples for different applications.

One consistent requirement for laboratory stirrers be they magnetic or overhead is a robust motor and protective motor housingldquoUsers need to be assured that stirrers will work reliably accurately and safely at all timesrdquo notes Nicole Kvasnicka product marketing manager at Heidolph North America Elk Grove Village ILldquoRegardless of the stirrer type the motor must always be protected from the lab environment.

Our magnetic stirrers are designed with various rpm ranges with single or multipoints to meet all laboratory needsOur portfolio includes stirrers with reliable and accurate speed control for general lab use and also unique stirrers that can be submerged in water baths used in CO2 incubators or featuring slow speeds for cell culture.

Overhead stirrers are specified often when either reaction or mixing volumes are very large typically above two liters but even more frequently when the operation is initially viscous or expected to develop significant viscosity.

Put in some more oxide of copper and clean the stirrer in it.

How to Use a Magnetic Stirrer APP.

Stirrer shafts with a diameter of 8 10 and 16 mm are most commonly usedFor standard applications up to a rotation speed of 350 rpm and a maxLength of 600 mm a shaft diameter of 10 mm will be sufficientFor stirring of high viscous products or shaft lengths over 600 mm it should be checked whether the use of a stirrer shaft with 16 mm will make senseFurthermore adequate stirrer bearings and chucks at the agitor should be available.

The high end of the price range for magnetic stirrers is the price entry point for overhead stirrers with the ldquosweet spotrdquo for laboratories in the 1000ndash5000 rangeOverhead designs provide significantly higher mixing stirring capability greater volume capacities and stronger agitation for processes involving highly viscous liquids.
