Capillary Tubes
Product Code : LSK-EAST-11174
Capillary Tubes (SKU LSK-EAST-11174) are clear glass tubes of 1 mm diameter for general laboratory use, including capillary rise and surface tension work in physics. They are heat and chemical resistant, so they also serve routine tasks in chemistry and science teaching labs. As a laboratory equipment supplier in India, Science Lab Supplies sources the tubes and sends them out of Ambala to schools, colleges, training institutes, tender contractors and distributors with the rest of their glassware.

Applications and Experiments for Capillary Tubes
Narrow glass tubes show capillary action: water rises inside them because of surface tension and adhesion to glass. They support the mechanical properties of fluids chapter of Class 11 physics, including the NCERT practical on surface tension by capillary rise, and general tasks in school and college laboratories.
- Class 11 physics: surface tension of water by the capillary rise method, with the tube held upright by a Retort Stand with Boss Head and Clamp.
- Showing that liquid rises higher in narrower tubes, dipping them into water in a graduated 500 ml Plastic Cylindrical Vessel.
- Middle-school science: simple demonstrations of capillary action.
- General chemistry and biology lab work that calls for fine glass tubes.
Standard Scope of Supply
Capillary Tubes are supplied as clear 1 mm glass tubes in the quantity agreed on your quotation. Stands, troughs and other apparatus used in capillary rise experiments are separate items, and each can be quoted alongside the tubes if your laboratory needs it.

Frequently Asked Questions
What diameter are these capillary tubes?
The tubes have a diameter of 1 mm and are made of clear glass that is heat resistant and chemical resistant, which suits capillary rise work as well as general laboratory tasks.
What are capillary tubes used for in a physics lab?
They are used to study capillary action and to measure the surface tension of water by the capillary rise method, where the height of the water column in the tube is measured.
Who supplies the Capillary Tubes?
Your quotation for these tubes is prepared by Science Lab Supplies in Ambala, India, and the tubes can be packed and dispatched together with the rest of the glassware and apparatus on the same order.
How should glass capillary tubes be handled?
Thin glass breaks easily and broken ends are sharp. Students should handle the tubes gently, dispose of broken pieces in a glass waste container, and work under teacher supervision.
