Capillary vessels Manufacturer,Supplier and Exporter in India
Product Code : SCL-MH-12720
The Capillary Vessels apparatus by Educational Instrument India is a practical physics laboratory instrument designed to demonstrate capillary action, surface tension, adhesion, cohesion, and liquid rise in narrow tubes. It helps students understand how liquids behave in small-diameter vessels and why liquid can rise or fall inside capillary tubes depending on the nature of the liquid and tube material.
This apparatus is ideal for school physics laboratories, college science labs, STEM classrooms, and educational training institutes. It provides a clear visual demonstration of the relationship between tube diameter and capillary rise, making it useful for teaching fluid mechanics, hydrostatics, surface tension, and real-life applications such as water movement in plants, ink flow, and liquid absorption in porous materials.

How to Use Capillary Vessels
Place the Capillary Vessels apparatus on a flat, stable, and dry laboratory table.
Ensure that the capillary tubes or vessels are clean and properly fixed in the stand.
Pour clean water or a suitable colored demonstration liquid into the container.
Carefully dip the lower ends of the capillary vessels into the liquid.
Allow the liquid to rise naturally inside the narrow tubes.
Observe the height of liquid rise in each capillary vessel.
Compare the liquid levels in tubes of different diameters if available.
Record the height difference and discuss the effect of tube diameter on capillary rise.
Use the observation to explain surface tension, adhesion, cohesion, and capillary action.
After use, empty the liquid container, clean the vessels carefully, and store the apparatus in a dry place.
Educational Applications
Capillary Vessels are widely used in physics laboratories to teach capillary action and surface tension through direct observation. The apparatus helps students understand why liquids can rise in narrow tubes and why the height of rise is greater in smaller diameter capillaries. It is useful for explaining water absorption in soil, movement of water in plant stems, ink flow in pens, towel absorption, and other real-life examples of capillarity.
