A hot plate is a heating element used to heat the solutions evenly in the beaker or vessel placed on it. The hot plate can be heated electronically using an electromagnetic field. Hot plates are easy and safe to use. They provide a fast and uniform heating with excellent performance. Working with hotplates saves a lot of time.

Types of Hot Plates
The hot plate comes in various types mainly Aluminium, Stainless Steel and Ceramic Glass. Different types of hot plates are used at different heating levels.
Aluminium Hot Plate - It is used to achieve thermal changes on the plate. This hot plate rapidly cools down and heats up instantly. The Aluminium Hotplate is best used when the experiment is done using adaptors.
Aluminium Hot Plate (Silicon Coated) - This type of hotplate is generally used for 5-Position and 15-Position Magnetic Stirrers. Silicon is skid-free. It prevents the beakers from slipping while the stirring is going on.
Stainless Steel Hot Plate (Polished) - This plate is used at single-position magnetic stirrers. It is a rust free and non-magnetic plate. It is non-reactive to glass beakers and vessels.
Stainless Steel Hot Plate (Ceramic Coated) - The ceramic Coated hotplate is easy to clean. After experimentation, no patches of the vessel or liquid are left on the plate. This plate is non-reactive.
Glass Ceramic Hot Plate- This hotplate is completely made up of glass ceramic. The melting point of this plate is above 1200º C. This type of hotplate is used when the liquids require excessive heat.
A Hot Plate with Magnetic Stirrer is a table top instrument used to quickly spin or mix a solution with the help of a generated magnetic field. The first Magnetic Stirrer was invented by Richard Stringham of Utah in 1917. He named the stir bar as “Flea” after perceiving certain changes while stirring like the way it jumped and spun in the flask. This laboratory instrument has fixed safety circuits and it meets the international safety standards. It is commonly used in the chemistry and biology labs to mix the components of the solutions and write observations.
