Transparent
For transparent/translucent liquids
Suspended Level
For transparent/translucent liquids. Ideal for testing at multiple temperatures because they have the same viscometer constant at all temperatures.
Dilution
For dilution of polymer solutions to provide an estimate of the molecular size and shape.
Reverse Flow
For transparent and opaque liquids. Must be cleaned, dried and refilled between repeat determinations.
Vacuum
A special type of reverse-flow viscometer for highly viscous samples (transparent or opaque). Accurately controlled vacuum is required to pull the liquid through the viscometer.
