NLG – 208 CONVECTION TUBE

To demonstrate the convection of heat in a liquid. Comprises a glass tube of O. D 20 mm. bent into a rectangle of size 350 x 250 mm. In the upper short side is a small tubule for filling, can be mounted vertically by a retort clamp, boss and stand. Convection currents can be generated by heating one of the lower corners of the rectangle. A small amount of Potassium Permanganate crystals dropped in to the tubule will act as an indicator.
