When to use the R180 ?
The
viscometer R 180 has been engineered for rapid and reliable viscosity
determination in both the laboratory and production environment.
Possible application includes: coatings, food, cosmetics, pharmacy and
many more.
Measurement principle
The Rheomat R 180 is a classical rotation-type viscometer which uses a motor driven bob rotating in a fixed cup. The sample is sheared in the gap between bob and cup. The measured shear stress is used to calculate the viscosity. Because of the versality of the R 180 viscometer a viscosity measurement can be made by immersing the measurement bob in an open vessel or in a closed measurement tube where temperature can be accurately controlled.
Measurement procedure
The
viscosity of a sample is characterized by a flow curve. These are
generated automatically by the R 180 in the measurement programs. Up to
50 flow curves can be stored and outputted to a printer or PC. Of course
single point measurements and constant shear measurements are also
available.
