Capillary viscometer: what is it?

Capillary viscometers measure the viscosity of liquids by measuring the flow time through a small tube. Viscosity is important in many industries, and capillary viscometers come in various designs. The efflux time is converted to viscosity using a unique conversion factor. Viscosity is measured in units of Pa*s or mPa*s, or in the cgs system, […]

What’s an Ostwald viscometer?

An Ostwald viscometer measures fluid viscosity by noting the time it takes for fluid to flow a certain distance through a U-shaped tube. Other types of viscometers include falling ball, piston, vibrational, rotary, and bubble viscometers. An Ostwald viscometer, also known as a viscometer, is a device used to measure the viscosity of fluid under […]

What’s a Viscometer?

Viscometers measure the viscosity of stable fluids and require a stationary fluid or device. Rheometers are used for fluids that change viscosity. Different fluids require differently calibrated viscometers. Measuring viscosity is important for chemical reactions and quality control. A viscometer is a device made to measure fluids for their viscosity, and scientists, manufacturing plants, chefs, […]
