Liquid Convection Apparatus

The GISCOM Liquid Convection Apparatus is a specially designed borosilicate glass tube used to visually demonstrate the convection currents that occur when a liquid is heated. It provides a clear and controlled setup for teaching heat transfer principles in physics and general science laboratories. This apparatus is essential for understanding thermodynamics, fluid movement, and temperature gradients, making it highly valuable for academic institutions, research labs, and industrial training environments.
