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.
A magnetic stirrer uses a rotating magnetic field to manipulate a magnetic stir bar or stir stick also called a flea immersed in a liquid for the purpose of mixingMagnetic mixing technologies often are preferred to mechanical mixing technologies as magnetic mixers are much quieter more efficient and require little to no maintenance.
Apr 24 2021nbsp0183321Most of the designs here are fairly simplistic but we’ll start with perhaps the most straightforward designThis set of instructions uses a fanbased setupThe main component of the stirrer is an old computer fan with magnets glued to itHere are the materials needed Computer fan.
Apr 26 2019 Locating your Freeze DryerFreeze drying machines eat up a fair amount of real estateThis is not a toaster oven or blenderThe main unit is about the size of a dorm fridge plus it has a hose and vacuum pumpMany owners buy a heavy duty rolling table to hold the unit but a counter top or table can get the job done.
Aug 22 2019nbsp018332Some 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 solidsInsufficient mixing You may find that your sample is.
