Capillary Tubes Apparatus, Each

Details

This Capillary Tubes Apparatus is perfect for demonstrating the relationship between capillary pressure and the bore diameter of a capillary tube. The apparatus consists of a metal frame arrangement with a base trough, an upper part that supports six capillary tubes, six bore holes fitted with corks, and six corresponding capillary tubes. When the trough is filled with water, the difference in heights of the resulting columns of water in the tubes is readily apparent. The metal frame measures approximately 5.5 inches long, 3 inches wide, and 5.5 inches tall. The bottom trough is approximately 0.8 inches deep. The total apparatus measures approximately 7.5 inches tall, 3 inches long, and 5.5 inches wide. The outer diameter and inner diameter of each tube are as follows: Tube 1: 8mm OD, 4mm ID; Tube 2: 7mm OD, 2mm ID; Tube 3: 8mm OD, 3mm ID; Tube 4: 6mm OD, 1mm ID; Tube 5: 8mm OD, 2mm ID; and Tube 6: 5mm OD, 1mm ID.
