Torricelli’s apparatus Manufacturer,Supplier and Exporter in India
Product Code : SCL-MH-12740
The Torricelli’s Apparatus by Educational Instrument India is a practical physics laboratory apparatus designed to demonstrate atmospheric pressure and the principle of a mercury barometer. It helps students understand how air pressure supports a column of liquid and how atmospheric pressure can be measured using a liquid column.
This apparatus is commonly used in school physics laboratories, college science labs, STEM classrooms, and educational training institutes. It is useful for teaching concepts such as atmospheric pressure, vacuum formation, liquid column height, pressure measurement, and the working principle of barometers.
Torricelli’s Apparatus is based on the famous Torricelli experiment, which showed that the atmosphere exerts pressure and can support a column of liquid in a tube. The apparatus provides a clear and practical demonstration of how pressure differences create a stable liquid column and how this principle is used in barometers.
It is suitable for teacher demonstrations, student observation, and laboratory practicals related to fluid pressure and atmospheric science.

How to Use
Place Torricelli’s Apparatus on a stable laboratory table.
Ensure the glass tube, reservoir, and supporting stand are clean and properly fitted.
Fill the tube carefully with the suitable demonstration liquid as per laboratory instructions.
Invert the filled tube into the reservoir, ensuring no air enters the tube.
Observe the liquid level falling and then becoming stable inside the tube.
Notice the empty space formed above the liquid column, known as Torricellian vacuum.
Measure the height of the liquid column using the provided scale.
Explain that atmospheric pressure supports the liquid column in the tube.
Record observations and compare the reading with the expected pressure value.
After the experiment, clean the apparatus carefully and store it safely.
