Pellat’s apparatus Manufacturer,Supplier and Exporter in India
Product Code : SCL-MH-12739
The Pellat’s Apparatus by Educational Instrument India is a useful physics laboratory apparatus designed to demonstrate the principle of liquid pressure and the hydrostatic paradox. It helps students understand that the pressure exerted by a liquid at a given depth depends on the height of the liquid column and density of the liquid, not on the shape or total volume of the container.
This apparatus is commonly used in school physics laboratories, college science labs, STEM classrooms, and educational training institutes. It is ideal for demonstrating hydrostatic pressure, liquid pressure at the bottom of a vessel, Pascal’s law, and the effect of liquid height on pressure.
Pellat’s Apparatus usually includes vessels of different shapes that can be fitted on a common base. When the same height of liquid is maintained in different vessels, students can observe that the pressure at the base remains the same, even though the vessels have different shapes and hold different amounts of liquid.
This apparatus provides a clear, visual, and practical way to explain an important concept in fluid mechanics and is suitable for teacher demonstrations and student practical experiments.

How to Use
Place Pellat’s Apparatus on a stable laboratory table.
Select one vessel and attach it properly to the common base or pressure chamber.
Ensure all joints are properly fitted to avoid leakage.
Fill the vessel with water up to a marked height.
Observe the pressure indication at the base, depending on the apparatus design.
Empty the vessel and repeat the experiment with another vessel of a different shape.
Fill the second vessel to the same height as the first one.
Compare the pressure indication at the base for both vessels.
Explain that pressure at the base depends on liquid height and density, not the shape of the vessel.
Record observations and repeat the experiment if required.
After use, empty the water, clean the apparatus, dry all parts, and store safely.

Frequently Asked Questions
- What is Pellat’s Apparatus used for?
Pellat’s Apparatus is used to demonstrate hydrostatic pressure and show that liquid pressure at the base depends on the height of the liquid column, not on the shape of the container.
- What principle does Pellat’s Apparatus demonstrate?
It demonstrates the hydrostatic paradox and the principle that pressure in a liquid at a given depth depends on liquid height and density.
- Is this apparatus suitable for school laboratories?
Yes, it is suitable for school science laboratories, college physics labs, STEM classrooms, and educational institutions.
- Does the shape of the vessel affect liquid pressure at the base?
No, if the liquid height is the same, the pressure at the base remains the same, even if the vessels have different shapes.
- Does Pellat’s Apparatus require electricity?
No, it is a manual physics demonstration apparatus and does not require electricity.
- What liquids can be used with this apparatus?
Clean water is commonly used for classroom demonstrations. Other safe liquids may be used depending on the experiment requirement.
- Why is Pellat’s Apparatus useful for students?
It helps students visually understand hydrostatic pressure, Pascal’s law, and the relationship between liquid height and pressure through practical observation.
