Equilibrium Tubes are perfect for demonstrating that liquid levels are independent of the shapes of the containing vessel. Liquid will rise to the same level across the vessel, regardless of its shape or size of the various tubes. This set of equilibrium tubes consists of a reservoir and 3 tubes of borosilicate glass, each with the same internal diameter but differing shapes.

• Plastic base is diameter 4 3/8″ (110 mm)
• Reservoir measures 5 1/2″ tall by 1 3/8″ diameter (140 mm tall by 35 mm diameter)
• Borosilicate glass

Note: Image shows blue liquid in the tubes for demonstration purposes only. Tubes are actually clear glass.
