Torricelli’s experiment apparatus Manufacturer,Supplier and Exporter in India
Product Code : SCL-MH-12758
The Torricelli’s Experiment Apparatus by Educational Instrument India is a physics laboratory apparatus designed to demonstrate atmospheric pressure and the principle behind the mercury barometer. It is widely used in school science laboratories, college physics labs, STEM classrooms, and educational training institutes.
This apparatus helps students understand how atmospheric pressure can support a column of liquid in a tube. Torricelli’s experiment is a classic demonstration that proves air has weight and exerts pressure on the surface of liquids. It also explains the formation of vacuum at the top of the tube, commonly known as Torricellian vacuum.
The Torricelli’s Experiment Apparatus is useful for teaching atmospheric pressure, barometric pressure, vacuum formation, liquid column height, and the relationship between pressure and fluid levels. It is suitable for teacher demonstrations and guided student observation in physics and general science classes.

How to Use
Place the Torricelli’s Experiment Apparatus on a clean, dry, and stable laboratory table.
Fix the glass tube vertically on the stand using the provided clamp or support.
Fill the tube carefully with the recommended liquid as per the laboratory procedure.
Invert the tube into the reservoir or trough without allowing air bubbles to enter.
Observe the liquid column inside the tube after it settles.
Note the empty space formed at the top of the tube, known as Torricellian vacuum.
Use the scale to observe or measure the height of the liquid column.
Explain that atmospheric pressure acting on the reservoir supports the liquid column.
Compare the observation with the principle of a barometer.
After the experiment, carefully release the setup and clean the apparatus as per lab procedure.
Store the apparatus safely after drying and inspection.

Frequently Asked Questions
- What is Torricelli’s Experiment Apparatus used for?
Torricelli’s Experiment Apparatus is used to demonstrate atmospheric pressure and the working principle of a barometer.
- What does Torricelli’s experiment prove?
It proves that air has weight and exerts atmospheric pressure, which can support a column of liquid in a tube.
- What is Torricellian vacuum?
Torricellian vacuum is the empty space formed at the top of the tube when the liquid column falls and settles due to atmospheric pressure.
- Is this apparatus suitable for school laboratories?
Yes, it is suitable for school science labs, college physics labs, STEM classrooms, and educational institutions.
- Does the apparatus require electricity?
No, the apparatus does not require electricity. It is a manual physics demonstration setup.
- Can students perform the experiment themselves?
Students can observe the experiment and may assist only under teacher or laboratory supervisor guidance.
- What concepts can be taught using this apparatus?
It can be used to teach atmospheric pressure, barometric pressure, vacuum, liquid columns, and pressure measurement.
- Is mercury required for the experiment?
Traditional Torricelli’s experiment uses mercury, but due to safety concerns, handling should be done only by trained personnel. Safer model demonstrations may be preferred in school laboratories.
