  • Stirring is a technique for obtaining homogenous mixes and (or) intensifying heat and mass exchange in mixers. In accordance with the state of aggregation of matter, liquids and bulk solids are mixed.
  • Most stirring occurs in vessels equipped with mixing equipment. Design of devices and mixers determines the kind and intensity of mixing. Magnetic stirring can be utilised over a wide range of temperatures and with any chemical agent, as well as in open and closed systems, under pressure or vacuum.
  • Using magnetic stirrers is the most prevalent method of mixing. The device comprises of two major components: a motor with a mechanism for stirring and control electronics.
  • Stir bars are rotated by a motor with a magnet on top, which mixes liquids. The control electronics monitor motor RPM and keyboard functionality.
  • Magnetic stirrers are designed to mix fluids of varying viscosity using a stir bar (sometimes known as a “flea”) that spins very rapidly.
  • Commonly used for sample preparation and analysis in chemistry, biology, and laboratory operations such as organic synthesis, extraction, oil analysis, pH measurement, dialysis, soil suspension, and buffer solution production.
  • The service performance and technical specifications of magnetic stirrers vary. The primary difference is in the design, which determines whether mixing occurs through rotation or oscillation.
  • When selecting a magnetic stirrer, you must consider the volume of the liquid container, the rotational speed, the oscillation intensity, and heating if you need to increase the temperature of the mixture.
  • A magnetic stirrer is an electromechanical device that mixes using an external magnetic field to rotate a stir bar placed in the mixture.
  • The stir bar revolves at various speeds and may mix up to one litre of liquid. Due to the fact that only a little magnet bar that is readily cleaned and disinfected must be inserted into the sample, the risk of contamination is reduced.
  • Magnetic stir bars function effectively in glass jars. The substance that has no effect on a magnetic field is glass. Due to its modest size, stir bars can only be used for relatively minor investigations (under 4 liters).
  • They may have problems with viscous liquids and thick solutions. The device’s plastic casing provides a decent barrier against spills.
  • Magnetic stirrers utilise a magnetic field and have no moving parts. The majority of magnetic stirrers use polypropylene housings. Ferrite is encased in polypropylene to create the stir bar.
  • These gadgets are trustworthy, universal, user-friendly, and compliant with all safety norms.
  • It is vital to consider oscillation intensity, time, and the possibility of heating.
  • Modern magnetic stirrers accomplish these jobs and create the necessary conditions with success. In addition, this device is a must-have for uniform, reproducible mixing or combining over lengthy periods of time, such as for sample mixing over multiple hours or overnight.
  • Magnetic stirrers are superior to motorised stirrers. They are more efficient and quieter. They have no external moving parts that can break or wear out.
  • For cleaning stir bars, lubricants that could cause product contamination are not required. Occasionally, magnetic stirrers are equipped with a hot plate for heating the liquid.
  • Magnetic stirrer safety is ensured by built-in fault diagnostics and automatic thermal shutdown. Magnetic stirrers are user-friendly and offer great productivity and precision.

Magnetic Stirrer Principle

The functioning concept of a magnetic stirrer repels like charges and attracts unlike charges. Micro motor drives a magnet to generate a rotating magnetic field to agitate the stirring bar in a jar, ensuring that the solution undergoes a well mixed reaction; stirring speed is adjustable; broadly applicable to solvents of varying viscosity. It is equipped with a temperature control system that can heat and regulate the sample’s temperature according to the experiment’s specifications, preserving the required temperature conditions and ensuring the mixed liquid fulfils the experiment’s specifications.

Types of Magnetic Stirrers

1. Mini Magnetic Stirrers

  • Mini stirrers are compact, take up little space, operate quietly, and have low vibration, making them easy to use.
  • It is resistant to dangerous and caustic laboratory chemicals.
  • Additionally, you may regulate the speed so that it does not exceed the maximum speed.
  • These miniature magnetic stirrers are utilised in laboratories and take up less space due to their diminutive size.
  • The presence of corrosive chemicals in the laboratory has no effect on this stirrer.

2. Magnetic Stirrer with Timer

  • This stirrer includes a built-in timer that allows us to control the established settings for a specific period of time, as its name suggests.
  • The rotations are stopped automatically when the timeout expires.
  • These stirrers are useful if you want the motor to switch off on its own.

3. Heavy Duty Magnetic Stirrer

  • Heavy Duty Magnetic Stirrer is chemically resistant and has a high mixing capacity.
  • A built-in electronic management system automatically regulates the speed in relation to the load.
  • The Heavy Duty Magnetic Stirrer may be the ideal tool for both laboratory and industrial applications.
  • With a great mixing capacity, these stirrers may be one of the best options for achieving satisfactory results.
  • They are also chemically resistant and durable.

4. Battery operated Magnetic Stirrer

  • When electricity is absent, battery-powered magnetic stirrers are perfect for use in the field, incubators, and other locations.
  • They are also portable and lightweight.
  • These magnetic stirrers are battery-operated and can be useful in areas with a weak or fluctuating power source.
  • For purposes of stabilisation, rubber feet are provided.

5. Air Operated Turbine Magnetic Stirrer

  • Air turbine magnetic stirrers employ low-pressure air to create magnetic stirrer rotations.
  • Ideal for usage in environments with potentially dangerous solvent vapours.
  • Air Operated Turbine Magnetic Stirrer is suitable for stirring up to 1 litre of solution.
  • A low-pressure air supply is employed for its power.
  • This stirrer eliminates the possibility of sparking associated with electrical sources.

Features of Magnetic Stirrer

Capacity

  • The water capacity of the agitator is always specified. It is shown, for instance, for the Maximum capacity: 4 litres.
  • The nominal capacity is significantly higher than the real capacity, as stirring with running water is plainly infrequent.
  • The micro variants have a 3-liter capacity and are suitable for at least 1 litre of surfactant solution and approximately 250 millilitres of emulsion.

Max. speed

  • The speed is denoted as rpm (rotations per minute). The speed is around 1,000 revolutions per minute.
  • Powerful variants have a maximum speed of 2500 rpm. Everything between 1000 and 1500 rpm should be OK for your laboratory.

Max. permitted temperature and humidity

  • If you work in a wet laboratory and your lab is located in tropical regions, or if you intend to mix hot materials, carefully examine the instrument’s maximum allowable working temperature and humidity before purchasing one.

Dimensions of the mounting surface

  • Clearly, the surface area determines the size of the beakers that can be used with each magnetic stirrer. The diameter of your beaker could not exceed that of the plate.

The magnet

  • Clearly, a magnet is required for a magnetic stirrer to function. Magnets are available in every size and shape imaginable, ranging from basic rods to beginnings, ellipsoids, discs, etc.
  • The stirring rod must be sized appropriately for your beaker. Typically 0.5-1 cm smaller than the diameter of the beaker.
  • If you are working with various beaker sizes, as you undoubtedly are, you will require several magnetic rods.
  • There are wonderful variants with several magnetic stirrers on a single plate, models that can be remotely controlled or pre-programmed, and ones with a USB hub.
  • These are highly handy (and perhaps required) in research laboratories and places where chemical reactions occur.
  • In a cosmetics lab, none of these additional features are required unless you have an enormous budget and no substantial expenses.

Parts of a Magnetic Stirrer

The magnetic stirrer for creating mixes is user-friendly and consists of two basic components: a stir bar and a hot plate stirrer device. The internal components of a hot plate stirrer device include a stationary electromagnet, a hot plate, a temperature control knob, and a speed control knob. Similarly, the stir bar retriever is an infrequently employed component of the magnetic stirrer.

Parts of a Magnetic Stirrer
Parts of a Magnetic Stirrer

1. Hot plate/Top plate

  • It helps offer a flat surface for holding and heating the vessel.
  • It is often composed of ceramic or stainless steel, both of which give excellent chemical resistance.

2. Stationary electromagnet: 

  • It is positioned within the stirrer apparatus to generate a magnetic field and rotate the magnetic needle (stir bar) immersed in liquid, so producing a high-velocity stirring action sufficient to homogenise the mixture.

3. Stir bar

  • The word “stir bar” or “spin bar” refers to a tiny, white, rectangular, Teflon-coated magnet.
  • These bars’ main purpose is to stir solutions.
  • They operate in conjunction with a stirring motor.
  • The stir bar is placed in a container containing liquid and then placed over a stirring motor.
  • When the stir motor is activated, the bar spins and the liquid is agitated.
  • The shape of the stir bar, which might be octagonal, circular, etc., is determined by the vessel shape and viscosity of the stirring medium.
  • The dimensions of the stir bar range from a few millimetres to a few centimetres.
  • It is a magnetic bar inserted in a solution-containing container for the purpose of agitating the liquid combination or solution.
  • It is covered with a nonreactive substance (such as polytetrafluoroethylene (PTFE) or glass) that shields the magnet and prevents contamination of the liquid medium in which they are immersed for agitation.
  • Two criteria determine the shape of the stir bar (e.g., octagonal, circular, etc.): the shape of the jar and the viscosity of the liquid being stirred.
  • Likewise, the size of the stir bar ranges from a few millimetres to a few centimetres.

4. Temperature controlling knob: 

  • It aids in temperature management based on the viscosity of the liquid, the volume of the liquid, and the size of the vessel.

5. Speed controlling knob: 

  • The speed control knob is used to modify the stir bar’s rotational speed (rpm) based on the viscosity of the liquid or the requirements of the project.

6. Stir bar retriever

  • Permanently incorporated within these magnets is PTFE (teflon) rod. It makes the recovery of magnetic stirring and spin bars from irritating and corrosive liquid samples in glass flasks safe and simple. However, it is utilised less frequently in magnetic stirring.

Operating procedure of Magnetic Stirrer 

  1. Preparing a container containing the liquid solution
  2. The container should be placed on the hotplate.
  3. Connect the hotplate to the mains to activate it.
  4. Adjust the temperature of the hotplate by pressing the temperature setting button.
  5. Insert the magnetic stick into a container containing a solution.
  6. Then, adjust the speed of the magnetic stirrer by turning the stirrer magnetic adjustment button clockwise.
  7. If the stirring speed is too fast, adjust it by twisting the magnetic adjustment knob counterclockwise on the stirrer.
  8. Stir the liquid solution until it is homogenous.
  9. Remove the magnetic stirrer from the liquid solution container when done.
  10. Disconnect the hotplate from the mains to turn off the appliance.
  11. Grab the container with your warm hands.

Magnetic Stirrer Calibration

Calibration is one of the maintenance activities for the magnetic stirrer. This is helpful for ensuring the precision of the tool. If the magnetic stirrer is utilised regularly, it is calibrated every three months. In contrast, if it is used infrequently, it is calibrated once a year. The temperature will be the focal point of this instrument’s calibration, as the heat energy produced has a significant impact on the results of stirring. Then, how is the magnetic stirrer calibrated?

  • Utilize a 300°C-calibrated thermometer to begin calibration.
  • Place the sample-containing beaker or flask in the centre of the heating plate.
  • To activate the device, press the ON button. Utilize the magnetic stirrer without a stir bar or magnetic stirrer.
  • Turning the temperature knob will adjust the temperature.
  • Insert a calibrated thermometer into one of the beaker’s sides.
  • Record the temperature displayed on the control panel and the temperature of the thermometer being calibrated.
  • Alter the temperature and repeat the procedure. Also, observe the temperature.

Now you are aware of the function of the magnetic stirrer. Hopefully, the reader will gain a better understanding of this scientific instrument. You can also search for additional information on the magnetic stirrer function on other websites.

Maintenance of a magnetic stirrer

  • It is advised that the instrument be stored on a flat, dry, and clean surface.
  • Do not connect the power source until the surface of the base has dried.
  • To prevent corrosive damage to the instrument, we recommend that you do not simply spray the cleaning solution directly onto it.
  • When the stir bar is not stirring during mixing, reduce speed or disconnect power to check.
  • To prevent extreme vibration during operation, medium speed operation can continue for eight hours, while high speed operation can continue for four hours.
  • To clean it, you can use solutions such as isopropyl alcohol and tension-containing water.
  • To prevent accidents, the instrument housing must be correctly grounded.
  • Regularly calibrate, particularly at temperature.

Precautions

  • To prevent accidents, instrument housing should be properly grounded.
  • When not in use for extended periods, power should be turned off and the device should be stored in a dry, well-ventilated area.
  • The instrument should be maintained clean and dry, solution should not flow into the machine, and power should be turned off when not in use to prevent machine damage.
  • During mixing, if the find stirrer is beating or not stirring, reduce the speed or disconnect the power to determine if the flat bottom of the beaker is in the correct area.
  • Not excessively long heating time with stirring; occasional use can extend shelf life; heating without stirring.
  • Medium-speed operation can operate continuously for eight hours, while high-speed operation can operate continuously for just four hours in order to prevent excessive vibration during operation.

Uses of Magnetic Stirrers

  • A magnetic stirrer is a device that is commonly found in laboratories and comprises of a revolving magnet or a stationary electromagnet that produces a rotating magnetic field.
  • This gadget is used to create a stirring rod, immerse it in a liquid, rotate it swiftly, stir or mix a solution, etc. Typically, a heating system is paired to a magnetic stirring system to heat the liquid.
  • It is utilised in microbiology laboratories to prepare a medium for cultivating bacteria.
  • It is used to get the highest possible extraction yield from plant material by minimising organic solvent use.
