A magnetic stirrer is a device widely used in laboratories and consists of a rotating magnet or a stationary electromagnet that creates a rotating magnetic fieldThis device is used to make a stir bar immerse in a liquid quickly spin or stirring or mixing a solution for exampleA magnetic stirring system generally includes a coupled heating system for heating the liquid Figure 6.
Apr 24 2021nbsp018332The basics of this stirrer are similar to some of those above using magnets mounted on a PC fanAdditional parts include a female power jack and a 12V motor speed controller with LCDThere are three 3Dprinted parts in total the main stirrer housing a stir bar with slots to hold two magnets and a mount for the fan with four slots for magnets.
Aug 22 2019nbsp018332Common Issues With Magentic StirrersSome of the main issues you’ll find with an overhead stirrer are Uncoupling of the bar The magnetic stir bar becomes uncoupled from the drive magnetThe bar becoming stuck The bar stops spinning for example in a viscous sample or in a mixture with lumps of agglomerated solids.
Aug 22 2019nbsp018332Magnetic stirrers are equipped with an internal drive magnet the size and strength of which limit the capabilities of the stirrerIf you’re using a unit with a relatively small weak internal drive magnet with too large a volume or too viscous a substance then you could run into issues including the bar becoming stuck and insufficient.
Aug 31 2021nbsp018332Helps To Reduce ContaminationMost laboratory ingredients are poisonous to humansThe 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 immense.

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 2021nbsp018332Working Principle of Magnetic StirrerAlso known as a Magnetic mixer the working concept of a magnetic stirrer is repelling for like charges and attractive for different chargesThe micromotor powers a magnet to create a spinning magnetic field that stirs the stirring bar in a vessel causing the solution to conduct a thoroughly mixed reaction.

Single point magnetic stirrers are designed with various speed ranges for use in all labsBasic Standard and Advanced stirrers are designed for general lab operating conditions and specialty stirrers are used for particular operating conditions as submersion in water or in CO 2 incubators.
So the magnetic stirrer took shape pretty quicklyI would feed the fan motor 24V through the pulse width modulation speed control board which would give it more power and more speed to handle big stirring jobsI added a switch so that the motor would run from 12V for lighter loads or from 24V for higher loads.
