Liquid Convection Apparatus, 1 Each

The United Scientific® Liquid Convection Apparatus is a rectangular borosilicate glass loop with a filling funnel for demonstrating convection currents in a liquid. The 20 mm outer diameter tube forms a rectangle of approximately 200 x 150 mm, so a colored liquid heated at one bottom corner can be seen circulating around the whole loop. Physics and physical science teachers use it for lessons on heat transfer and density. A stand, clamp, heat source and liquid are required.
