Convection Demonstration Tube

Convection Demonstration Tube for Educational Demonstrations

Educational aid in the shape of a bent rectangular glass tube with a top inlet, designed to effectively demonstrate the convection phenomenon in liquids.

The experiment consists of filling a fixed tube with water, adding a coloring agent (food coloring, ink, potassium permanganate), heating one corner of the tube, and observing how the water in the tube begins to circulate (convection), which is clearly visible due to the movement of the colored water in the tube.

During the demonstration the aid is best held with a laboratory clamp or suspended on a stand (not included).

Dimensions: 20 x 15 cm.
