Viscometry

 Viscometry is the study of the viscosity or resistance to flow of fluids and to continue the progression, measured using a viscometer!

There is an excellent introduction to Viscosity in the Wikipedia web site for those of us who need to remind on the basics, terms and the concepts..

Viscometers differ from Rheometers in that they take measurements under only one set of flow conditions.

There are numerous different approaches to measuring viscosty in fluids from falling balls to Ostwald viscometers, vibrating viscometers and to rotational viscometers and they each have their place in a laboratory.

Particular Sciences is only concerned with the latter ones; and if course with Rheometers that study fluids under differing flow conditions.

But viscosity is also seen with GPC and SEC systems – as an approach to characterising molecular weights without tedious and inaccurate calibrations. This was pioneered by Dr. Max Haney who founded Viscotek in 1984.

Viscosity as a topic was much studied by famous physicists-  in the 19th century by George Stokes, by Robert Hooke and Isaac Newton who wrote the definitive equations across the 17th and 18th centuries.
