The magnetic stirrer consists of two main parts: motor with stirring mechanism and control electronics. Motor movement with a magnet on top causes rotation of stir bars which mix liquids. Control electronics supervises motor RPM, keyboard functions. Magnetic stirrers are designed for mixing fluids of different viscosity with the help of a stir that spins very quickly. They are commonly used for sample preparation and analysis, in chemistry Lab, biology lab, Pharmacy Lab and in such laboratory works as organic synthesis, extraction, oil analysis, pH measurement, dialysis, soil suspending, preparing buffer solutions where it is often needed to mix several types of liquids to get homogeneous mixtures. Magnetic stirrers have different service performance and technical parameters. The main difference is in the design which means that mixing occurs by rotating or oscillating processes. When you choose a magnetic stirrer, you should take into consideration the volume of the liquid container, the speed of rotation, the oscillation intensity, and heating if you need to raise the temperature of the mixture. A magnetic stirrer is an electromechanical device that mixes with the help of an external magnetic field that rotates a stir bar placed in the mixture. Stir bar rotates at different speeds and can mix volumes up to one litter. Since only a small magnet bar that can easily be cleaned and sterilized has to be put inside the sample, the risk of contamination is minimized. Magnetic stir bars work well in glass vessels. Glass is the material that doesn’t affect a magnetic field. The stir bar has a limited size that is why it can be used for relatively small experiments. They can have difficulties with viscous liquids and thick suspensions. The plastic case of the device serves as good isolation from spills. Magnetic stirrers have no moving parts and use a magnetic field. The housing of the most magnetic stirrers is made of polypropylene. The stir bar is made of ferrite enclosed in polypropylene. 

Magnetic Stirrer with hot plates is reliable, universal, and easy to use and meet all kind of safety standards. It is necessary to consider the oscillation intensity, time, and possible heating. Modern magnetic stirrers successfully deal with these tasks and provide the right conditions. Besides, this device is a must be an instrument for consistent, reproducible mixing or mixing over a long time, for example, for multi-hour or overnight sample mixing. Magnetic stirrers have an advantage over motorized ones. They are quieter and more efficient. They have no moving external parts to break or wear out. For cleaning stir bars, you don’t need lubricants which could be the reason for contamination of the product. Sometimes magnetic stirrers include a hot plate for heating the liquid. Built-in fault diagnostics and automatic thermal shutdown ensure the safety of magnetic stirrer usage. Magnetic stirrers are easy to use and they ensure high productivity and accuracy. 

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

The magnetic stirrer is used in many biological labs, including microbiology labs also. A magnetic stirrer is a laboratory device consisting of either a rotating magnet or stationary electromagnets creating a rotating magnetic field. This device is used to cause a stir bar immersed in a liquid to spin very quickly, agitating, or mixing the liquid. A magnetic stirrer often includes a provision for heating the liquid. Stirrers are often used in laboratories, especially in the field of biology and microbiology. They are preferred over gear-driven motorized stirrers because they are quieter, more efficient, and have no moving external parts to break or wear out (other than the simple bar magnet itself). Due to its small size, a stirring bar is more easily cleaned and sterilized than other stirring devices. Magnetic stirrers avoid two major problems with motorized stirrers. Firstly, motorized stirrers use lubricants, which can contaminate the reaction vessel and the product. Secondly, in motorized stirrers, the sealing of the connection between the rotating shaft of the stirrer and the vessel can be problematic, especially if a closed system is needed. Magnetic stirrers also have drawbacks. For example, the limited size of the stirring bar means it can only be used for relatively small experiments. In addition, viscous liquids or thick suspensions are extremely difficult to mix using this method, although there are some stirrers with special magnets to overcome this problem. 

Components of Magnetic Stirrer with Hot Plate:

1. Base with power switch, two control knobs, and LED indicators
2. Teflon-coated magnetic stir bar (1-inch length)
3. Power cord
4. Support stand (2-piece support rod, right-angle clamp, and thermometer holder)

How does a magnetic stirrer work (Working Principle)?

Magnetic stirrer working principle is repulsive for like charges and attractive for unlike charges. Micromotor drives magnet to generate rotating magnetic field to stir the stirring bar in a vessel, making solution conduct completely mixed reaction, stirring speed is adjustable, widely applies to solvent stirring in different viscosity. It equips with a temperature control system, which can heat and control the temperature of the sample according to experiment requirement, maintaining the needed temperature condition and guaranteeing the mixed liquid meets the experiment need. 

How to maintain a magnetic stirrer with Hot Plate?

1. Put the bottle on the working table.
2. Switch on the power switch, the indicator will light.
3. Choose to heat, turn on the heating power switch, the heating indicator will light, this means the heater is working now. Insert the sensor solution, adjust the thermostat knob to the desired temperature scale.
4. Adjust the speed control knob, rose to the required speed.
5. After work, set the speed control knob at the lowest speed position, the heating switch is in a non-working state, turn off the power switch, cut off the power supply.
6. Clean the working surface and sensor, make sure no water and dirt on it.

Precautions when using a magnetic stirrer with Hot Plate:

1. Instrument housing should be properly grounded to avoid accidents.
2. When unused for long periods, should cut off the power, store a dry and ventilated place.
3. The instrument should be kept clean and dry, prohibit the solution flows into the machine, to avoid damage to the machine, cut off the power when not working.
4. During mixing, when find stirrer is beating or non-stirring, reduce speed or disconnect the power to check whether the flat bottom of the beaker, location is positive.
5. Stirring heating time not too long, intermittent use can extend the life, not heated without stirring.
6. The medium-speed operation can continuously work for 8 hours, high-speed operation can continuously work for four hours, to prevent severe vibration during operation.

Let us see and try to understand the basic apparatus used in School chemistry laboratories and what are their specific uses when performing any chemical experiment. The first and foremost apparatus that every student or member entering the chemical laboratories should be aware of is of the safety apparatus. Safety protocols should be followed very strictly in these areas as a small mistake or misfortune can lead to big casualties and severe outcomes. One should always make sure to wear fully covered shoes and not sandals or slippers in any laboratory.

1. Safety goggles: One must wear safety goggles in the chemistry lab. It protects the eyes from irritation that may arise from any chemical or fumes coming out during the experiment. In case of any accidental splashing of chemicals or acids, it also protects us from the blindness of the eyes 
2. Lab Apron: Lab apron has a similar role as the safety goggles, but here the difference just being that instead of protecting just the eyes, it is usedprevention of any injury in case of spills or splashes. for prevention of any injury in case of spills or splashes. 
3. Latex gloves: These gloves are useful in handling chemicals, acids, or any solutions to prevent direct contact from these chemicals with the bare hand sand skin.  
4. Beakers: Beakers are cylindrical utensils made up of borosilicate glass, with a flat bottom and the upper opening having a rim around it along with a spout. The spout on their rim’s aids in the proper pouring of solutions and they do not have any covering on the top. Most of the time watch glasses are used to cover their solutions. They are of varying sizes and are used to hold, heat, or mix substances with a proper measure. Although they come with graduated calibrations, they are not meant for precise calculations of solutions, and as such other apparatus come handy in this.
5. Conical flasks: Conical flask, also known as Erlenmeyer flask, is an apparatus having a flat bottom and a long narrow neck, which allows easy mixing of the solution without spilling out the content. Since the flask has a narrow long neck, it is also used to gently heat the content inside with a gentle swirling motion of the flask. The flask can also be covered using a rubber cap or cork. One should always remember never to heat any flask with its cap on as it will lead to pressure and gas build up inside the closed flask and lead to explosions.
6. Boiling flask: Boiling flasks, also known as Florence flask, has a round bottom with a long neck. It can be capped using rubber or glass stoppers and is mostly used to hold solutions that can be easily heated with proper swirling motions for proper mixing.
7. Test tubes: The next very common apparatus are the test tubes. They are usually cylindrical pipes made up of glass, with a circular opening on one side and a rounded bottom on the other. They come in different sizes but the most common standard size is 18*150 mm. Test tubes are one of the most important apparatus as they are functional from storing to mixing reagents in any chemical or biological reactions. They become very handy when a large number of samples need to be tested for qualitative assessment of any test.
8. Watch glass: This apparatus is made up of a concave piece of glass. It is normally used to hold solids, evaporate liquids, and heat small quantities of different substances as per the need of the experiment. Sometimes, they also become functional in serving as a lid for the beakers.
9. Crucibles: Crucibles are made up of porcelain and are used to store and heat substances when required to be heated at high temperatures since glassware is not always suitable for such high heat involving experiments.
10. Funnels: Funnels are necessary equipment to pour substances and solutions in narrow-mouthed test tubes and conical flasks. There is variety of its available, the most common ones are filter, thistle, and dropping funnels.
11. Graduated cylinders: These are some cylindrical apparatus with several markings up and down the length of the container with the primary function dealing with proper measurement of a specific volume of liquid with precision. While taking readings, one needs to be careful to take into consideration the reading with respect to the meniscus of the liquid. 
12. Volumetric flasks: This is one of the most important glassware of any lab, which is made up of glass and is calibrated to hold a precise volume of liquids at any precise temperature. Different sizes of volumetric flasks are available, each calibrated for exact measurement of liquids and solutions. It is mostly used in the preparation of standard solutions. 
13. Droppers: The dropper, also known as Pasteur pipette, is a common small apparatus, usually made up of plastic or glass cylinder, having a small nozzle on one side and a rubber holder on the other. It is used to put the liquids or solutions in any medium dropwise, that is, one drop at a time, necessary equipment when any reagent is required in an extremely small amount in a solution. 
14. Pipettes: Pipettes are of varying sizes, designed for accomplishing specific goals of volumes. These are narrow glass cylindrical pipes, used for measuring an exact volume of liquid and placing it into another container. 
15. Burettes: A very popular equipment, mostly used in the titration reactions, and is a handful in delivering a known volume of any substance to other equipment. This apparatus is a long-graduated tube, with a stopcock present at the lower end and a narrow opening at the bottom. They are usually set up by using a burette clamp in combination with a ring stand. It usually comes in the sizes of 10ml, 25ml, or 50ml. 
16. Ring stands, rings, and clamps: These are the apparatus that are used to suspend burettes, flasks, crucibles, etc. either above other containers or above Bunsen burners for heating purposes. While heating these flasks, wire mesh is a necessary apparatus for the even distribution of the heat. 
17. Tongs and forceps: Tongs, though not much in use, are common and basic apparatus in any lab. They are used to grasp and lift hot vessels and harmful substances during any kind of reaction taking place in the lab. Forceps are used to grab small things like solid chemicals that are broken into chunks. 
18. Spatulas and scopulas: These laboratory spatulas are very much similar to the kitchen like spatulas found in our home but they are just very smaller in size in comparison. The spatulas are usually resistant to heat and acids, hence making them suitable for large range use in the laboratory experiments. 
19. Thermometer: Every lab is equipped with a basic thermometer as many a time, certain chemical or biological reaction can be carried out in any particular temperature range only and so to proceed, the thermometer becomes very necessary to measure the temperature of the required solution before moving forward with further reaction procedure. 
20. Bunsen burner: This apparatus produces a single open flame and it is used for heating and sterilization purposes in the various experiments conducted in labs. 
21. Litmus and filter papers: These two cannot be called apparatus in a proper way, but they serve as one of the most important and basic things that will be required in any kind of laboratories. The litmus paper serves to identify the pH of any solution by changing colors whereas, the filter paper serves in the filtration process. 

These items are the basic and must apparatus of any chemistry laboratory. Along with these, we will also get to see weighing balance, brushes to clean test tubes, wash bottles which are also used for cleaning purposes. As these apparatuses serve the basic, every student must get familiar with all this equipment and their working to have safe and sound practical experiment experiences in the chemical laboratories.
