Liquid Convection Apparatus

Item 3205-00

Use this device to demonstrate the phenomenon of thermal convection in liquids caused by temperature variation. It consists of a rectangular-shaped borosilicate glass tube, 6″ (150 mm) W x 8.25″ (150 mm) H, with a funnel-shaped opening at the top for filling liquids. When this tube is filled with water and heated at 1 corner after adding a dye, potassium permanganate crystals, saw dust, or aluminum powder, the movement of colors or particles illustrates the formation of convection currents.
