Liquid Level Apparatus
Product Code : LSK-PL-10341
Liquid Level Apparatus (SKU LSK-PL-10341), a form of communicating vessels, shows that several connected bodies of water settle at the same height whatever their shapes. At an elementary level it demonstrates that pressure is transmitted equally through a liquid under gravity and air pressure; older students can use it for more advanced pressure ideas. Made by Science Lab Supplies at its Saha, Ambala plant (Plot 448, HSIIDC Industrial Area), it reaches schools, colleges, tender contractors and distributors without a middleman.
Specifications
The apparatus links several water bodies of different shapes so that they share one liquid. When water is poured in, every part settles to the same level, showing that liquid pressure depends on depth rather than on the shape or width of the container. The same set also supports more advanced pressure work.

Applications and Experiments for the Liquid Level Apparatus
The apparatus answers a common student question: why does water in a wide vessel not push the level higher in a narrow one? Because pressure in a liquid depends only on depth, all connected parts reach one level. It suits primary, middle and secondary pressure lessons and is a staple of school physics lab equipment in India.
- Primary and middle-school science: water finds its own level.
- NCERT Class 8 science, pressure: liquids exert pressure that depends on depth.
- Class 11 physics, mechanical properties of fluids: hydrostatic pressure and Pascal’s law.
- Everyday links such as water tanks, water (hose) levels and supply systems.
Standard Scope of Supply
The Liquid Level Apparatus is supplied as a single unit as described above. Water, and any colouring you add to make the levels easier to see from the back of the class, are provided by the laboratory. Optional items for further pressure work can be listed on the quotation.
Packing, MOQ and Lead Time
You may request a price for one apparatus or for a batch covering several labs or schools. The quotation will state packing, delivery time and price for that quantity, and further fluid-pressure items can be combined on the same quotation to simplify ordering.
Registered as an exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Kenya, Ghana, Ethiopia, Tanzania, Uganda and the UAE. Schools, distributors and tender buyers can reach us via the contact page or enquiry cart; tender details are on the lab tender page.
Frequently Asked Questions
What does the Liquid Level Apparatus prove?
That connected bodies of water come to rest at the same height regardless of their shapes, because pressure is transmitted equally through the liquid under gravity and air pressure.
Is it only for younger students?
No. It works as an elementary demonstration, and more advanced variations on liquid-pressure principles can also be explored with it in higher classes and college physics.
Is this the same as a communicating vessels apparatus?
It demonstrates the same principle of liquids finding a common level. The related Communication Vessel Apparatus listed below is a separate model with its own construction and can be ordered alongside it.
Where is the apparatus made?
Science Lab Supplies produces it in its own factory in Saha, Ambala, India. You deal with the manufacturer directly, and the quotation is issued by that factory.
Related Fluid Pressure Apparatus
These four Physics Lab items build on the equal-level demonstration: another vessel set, a Pascal’s law demonstrator, a hydraulic press model for pressure transmission and a capillary apparatus that shows where equal levels break down. Together they cover the fluid-pressure topic.
- Communication Vessel Apparatus — four glass pipes of different shapes on a common pipe.
- Pascal's Law Demonstrator — 8 cm metal sphere with nozzles and piston.
- Hydraulic Press Model — two cylinders of different diameters with pistons.
- Capillary Tube Apparatus — six tubes of different bores in a trough.
