In the same category of capillary viscometers, tube viscometers (Figure 2C) use a horizontal tube fed by a pressurized tank to determine viscosity.2 In these instruments, the pressure is determined at ...

WHEN a capillary-tube viscometer is used for determining the apparent viscosity of a suspension of discrete, solid particles in a liquid, it is found that the measured viscosity varies with the bore ...

In this interview, AZoM speaks to Dr Larry Spino about Viscosity analysis, what is constant pressure viscometry and its benefits and what PAC L.P. offers to fulfil viscosity analysis needs. Viscosity ...

Traditional viscometers rely on capillary flow, and falling balls are simple and effective means for measuring fluid viscosity over a large range. However, their low measurement throughput and lack of ...

This article discusses how using the hand-held, solvent-free SpectroVisc Q3000 Series in the field delivers accurate kinematic viscosity measurements immediately, even when compared to conventional ...

The United States Pharmacopeia has stated that references to General Chapter <911> "Viscosity" will be changed to General Chapter <911> "Viscosity-Capillary Viscometer Methods," <912> "Rotational ...

Viscosity, or a fluid’s resistance to flow, is independent of the rate of shear or shear stress, at a given temperature, for Newtonian fluids. Non-Newtonian fluids such as polymer solutions often ...

Capillary viscometer and flow cups (orifice viscometers) The working principle of these instruments is based on the determination of the time needed for a standard volume of fluid to pass through a ...
