Viscosity Apparatus Stokes Method
Product Code : EL-EAST-10421
Viscosity Apparatus (Stokes Method) from Lab Exports demonstrates Stokes' Law for determining the viscosity of a liquid, using a borosilicate glass tube (approximately 30 cm diameter, one metre long) standing vertically between two upright bars on a heavy cast iron base. The lower end takes a rubber cork without holes; the upper end takes a rubber cork with a funnel. It is supplied with two rubber band index marks and six steel balls of different diameters, without lead shot, and both ends of the tube are open. Lab Exports manufactures and exports this apparatus from India to schools, colleges and laboratories worldwide.
