The 3B Scientific UHH-VISKOS Hoppler-type falling sphere viscometer has a 0.5 to 70,000 millipascal seconds (mPa s) measuring range and is suitable for measurement of dynamic viscosity of transparent Newtonian fluids. It includes six spheres of size #1 and #2 borosilicate glass, size #3 and #4 nickel-iron, and size #5 and #6 steel for testing a variety of fluids. The 40mL viscometer tube is housed in a water bath for temperature-controlled viscosity testing.The viscometer includes a test certificate with data values for sphere constant K and density â´ for converting the sphere fall duration to viscosity. This falling sphere viscometer is suitable for testing a variety of fluids, such as oils, gases, polymers, cosmetics, detergents, and foods for use in a variety of industries.

A viscometer, also called a viscosimeter, is an instrument used to measure the friction caused by the relative motion of a Newtonian fluid and a known surface, and is usually expressed in units of poise (P), centipoise (cP), pascal seconds (Pa s), and millipascal seconds (mPa s). Viscometers have several forms, including but not limited to falling ball, rotational, vibrating, capillary, funnel, and bubble. A falling ball viscometer measures the time it takes for a ball of known diameter and density to fall through fluid in a cylinder of known diameter. A rotat...
