Glass Capillary Tube - Physical Experiment Equipment for Schools and Labs - Teaching Instrument

Use: For secondary schools to demonstrate capillary phenomenon.Construction: A plastic cup holder and three glass capillaries with different inner diameters.Instructions for use: Insert three capillaries into the wells and slowly add the colored water to the reservoir until it is immersed in the capillary. At this point, it can be seen that the rise temperature of the colored water in the tube is different, and the smaller the inner diameter of the capillary, the higher the color water rises.Matters needing attention: Colored water is required to avoid clogging the capillary.

• 1. Ideal for demonstrating capillary phenomena in high school science classrooms.
• 2. Includes a plastic cup holder and three glass capillaries with varying inner diameters.
• 3. Simply place the capillaries in the designated wells, add colored pyridine water to the reservoir, and observe the different water rise levels. Smaller inner diameters result in higher rises.
• 4. It is crucial to use pyridine as the colored water to avoid capillary blockages.
• 5. Enhance students' comprehension of capillary action principles in physics and chemistry with this visually engaging educational tool.
