Instrument to study superficial tension Manufacturer,Supplier and Exporter in India

Product Code : SCL-MH-12741

The Instrument to Study Superficial Tension by Educational Instrument India is a practical physics laboratory apparatus designed to demonstrate and study the surface tension of liquids. Surface tension, also known as superficial tension, is the property of a liquid surface that allows it to behave like a stretched elastic membrane.

This apparatus helps students understand important concepts such as cohesive force, adhesive force, molecular attraction, liquid surface behavior, capillary action, and the effect of impurities or temperature on surface tension. It is widely used in school physics laboratories, college science labs, STEM classrooms, and educational training institutes.

The Instrument to Study Superficial Tension is suitable for teacher demonstrations and student practical experiments. It provides a clear and hands-on learning experience for understanding how liquid molecules at the surface create tension and how this force affects liquid behavior.

How to Use

Place the instrument on a clean and stable laboratory table.

Clean the wire frame, ring, or plate used for the experiment to remove dust or oil.

Fill the liquid sample, such as water, into a suitable container or tray.

Attach the ring, frame, or plate to the measuring arrangement as per the experiment method.

Slowly bring the liquid surface in contact with the ring or frame.

Gently lift the ring or frame and observe the force required to detach it from the liquid surface.

Record the reading using the spring balance or measuring scale, depending on the apparatus design.

Repeat the experiment for accuracy and compare readings with different liquids if required.

Discuss how molecular attraction creates surface tension.

Clean and dry the apparatus after use and store it safely.
