The development of scientific methods and technologies has simplified the experiments carried out in laboratories and research labs. Magnetic stirrers are the most popular method of mixing. Stirring is done to achieve homogenous mixes and to increase heat and mass transfer in the mixers. There is a mixing of liquids and bulk solids under the condition of matter aggregation. Stirring is primarily done in vessels equipped with mixing gear. The type of mixing and how intense it is determined by the design of the devices and mixers. Magnetic stirring can be performed in open and closed systems, under pressure or vacuum, and across a large temperature range and with any chemical agent.
Working Principle of Magnetic Stirrer
Also known as a Magnetic mixer, the working concept of a magnetic stirrer is repelling for like charges and attractive for different charges. The 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. The stirring speed may be adjusted, and it may be used to stir solvents of various viscosities. It is equipped with a temperature control system that can heat and adjust the temperature of the sample as per requirements, ensuring that the mixed liquid fits the experiment necessities.
Applications of Magnetic Stirrer with Hot Plate
A hot plate is a self-contained electrical warmer where temperature control is done via heating components. Hot plates are commonly used in science to heat materials in glass beakers, flasks, vials, bottles, and other containers. They are tiny enough to fit on laboratory tabletops and have a modest footprint. Electronic hot plates are usually more constant and reliable than gas burners.
Magnetic stirrers are used to mix fluids of various viscosities using a fast-spinning stir. They are commonly used in biology labs, chemistry labs, and pharmacy labs for sample preparation and analysis, as well as for organic synthesis, oil analysis, soil suspension extraction, dialysis, pH monitoring, producing buffer solutions, among other laboratory tasks to get homogenous mixtures.
Today many manufacturers let one buy magnetic stirrers with hot plates online. Based on the specifications provided by the companies, it becomes easy to choose the best magnetic stirrer for the work. The magnetic stirrer with heated plates is consistent, versatile, and simple to use, and it complies with all safety regulations. It’s important to think about the oscillation’s intensity, duration, and potential heating. Modern magnetic stirrers are capable of completing these works and provide the necessary conditions.
How do keep a Magnetic Stirrer with a Hot Plate in Good Working Condition? 1
1- Place the bottle on the countertop.
2- When you turn on the power, the indicator will light up.
3- Choose heat; turn on the ‘heating power’ switch. This will light up the heating indicator that shows that the heater is now operational.
4- Adjust the ‘thermostat’ knob to the desired temperature scale after inserting the sensor solution.
5- Rise to the necessary speed by adjusting the speed control knob.
6- Set the ‘speed control’ knob to the lowermost speed position after work, the heating switch should be off, turn off the power switch, and turn off the power supply.
7- Make sure the working area and sensor are clean and free of dirt and water.
A 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 field. The stir bar revolves at various speeds. The risk of contamination is reduced because the sample only requires a short magnet bar that can be readily washed and sanitized.
In glass jars, magnetic stir bars function effectively. The substance that does not affect a magnetic field is glass. Because the stir bar is limited in size, it can only be utilized for smaller experiments. Magnetic stirrers have a variety of service capabilities and technical specifications. When selecting a magnetic stirrer, consider the capacity of the liquid container, the oscillation intensity, the speed of rotation, and heating if you require increasing the temperature of the mixture.
