Capillary Phenomenon Demonstrator Glass Capillary Demonstration Physical Experiment Equipment Teaching Instrument

1. Use: For secondary schools to demonstrate capillary phenomenon. 2. Construction: A plastic cup holder and three glass capillaries with different inner diameters. 3. 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. 4, matters needing attention Colored water is required to avoid clogging the capillary.

• 1. Use: For secondary schools to demonstrate capillary phenomenon.
• 2. Construction: A plastic cup seat and three glass capillaries with different inner diameters.
• 3. Instructions for use: Insert three capillaries into the wells and slowly add the colored water into the liquid 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.
• 4, note: colored water should be pyridine, so as not to block the capillary.
