Laboratory shaker are devices that are used in laboratories to mix liquids. In a laboratory, there are several equipments that are used for various research and development projects as well as for handling and preparing of chemicals. So, laboratory shaker are used for carrying out these experiments and for mixing or stirring liquid.

Mixing and stirring are extremely important in performing different kinds of experiments, as they act as catalyst which is used to promote the molecular reactions of chemical substances. How frequently and fast a laboratory shaker mixes the chemicals, is what determines its efficiency. There can be different types of shakers some may be slow in speed and some may be fast, depending upon the material that needs to be mixed.

The most popular type of shakers that are used in a laboratory is magnetic stirrer. Laboratory shakers has been replaced by the Magnetic stirrer as it is provided with the latest and advanced technologies. Laboratory shakers are double walled convection units, the outer body of this is made up of thick PRPC sheet and the inner chamber is made of heavy gauge stainless steel of SS-304 grade. The gap between these two walls is filled with high grade mineral glass wool which actually ensures maximum thermal efficiency. The shaking speed of these shakers is between 80RPM to 400RPM.

Now if we discuss about magnetic stirrer, they are comprised of a flat base, and a power cord. A magnetic pellet is coated with plastic so that it cannot hinder with the chemical reactions that is placed inside the container, surrounded by the medium that is to be mixed. After this, the unit is switched on which makes the motor to function and is ready to spin. The shaft is connected to second magnet that spins the material which is inside the mixing container. In these materials coating can be done, and this can be for reactive uses and non reactive uses. These shaking machines can also come in heating or cooling element that somehow helps in the catalytic reaction. This process is particularly useful to chemists as there are times when the reaction is reduced with certain temperature. There are different types of mixers; some are based on swirling technology while some come in different shapes and sizes. There are large platform mixers and inverting mixtures which are used in microbiology and several other bio technical equipments. These equipments are extremely important for a laboratory.
