SCOPE :-

The hot plate is a single device that can heat liquids. A hot plate is used to heat objects or containers. Flasks or beakers containing solutions can be heated directly or indirectly depending upon the shape of the container and the desired temperature. Always use the lowest temperature setting possible when heating.

Beakers and Erlenmeyer flasks can be heated directly on a hot plate, Hot air oven price in India. These containers have a flat bottom and heat will be spread evenly throughout the solution especially if the solution is also stirred. Controlling the temperature of the solution is more difficult when using direct heating. Even low temperature settings on the hot plate may reach temperatures in excess of 100°C and the temperature of the plate will fluctuate due to air currents or room temperature changes.

When the container does not have a flat surface or more control over the temperature is required, indirect heating should be used. To indirectly heat a container, set up a bath on the hot plate. Assemble a bath by placing a liquid or solid in a large beaker (or a similar container). The bath is heated and the sample is placed in the bath.
Selection of the liquid or solid can help to control the temperature of the bath. If a sample is not to be heated above 100°C, then water can be used in the bath (since liquid water cannot be heated above its boiling point). Likewise, other liquids could be chosen to control the maximum temperature. Liquids should not be flammable or present any other hazards.

Remember to replace the liquid as it evaporates. Sand is a common solid used in heating baths. Sand can be heated to very high temperatures without having to be replaced due to evaporation.

NOTE:-NEVER heat a volumetric flask. You might change its volume by distorting the glass.
