Equipment Overview
Generally called an inner cylinder rotational viscometer, this device measures viscosity by rotating the inner cylinder in the molten liquid of a container that serves as the outer cylinder and measuring the torque generated.

Features
This system uses the highly stable VT-550 (manufactured by Haake, Germany) for automatic measurement, data processing, and other automated measurement systems.
